HiFiMAN RE-400 Review

HiFiMAN RE-400 Review

Thanks to Head Direct for the sample.

First Impressions:  Since these are pre retail they aren’t in anything fancy.  I don’t mind that though, I’ve heard a bunch of HiFiMAN IEM’s and everyone one of them has been jaw droppingly good.  I have little doubt that the RE-400 is going to be any different but given they seem to be replacing the aging yet still stunning RE-0 I don’t know quite what to expect but I do expect greatness.

First listen and they are not disappointing.  They seem to have the same RE-0 level of detail but seem vastly easier to drive and much bigger sounding.  The bass too feels far more vigorous as that was always a complaint of the old 0.  Oh god, are these maybe big and balanced enough to be GR07 challenging?  Oh because if they are and I think they will, they I think will be besting them in the detail retrieval department.  Oh my, suffice to say after a couple of hours listening is pretty impressed that it’s going to kick the snot out of just about everything near its price!

Source: Hisoundauido Rocoo BA predominantly.

Lows:  To many out there this is still going to be lacking in the lows.  Quantity wise it’s a step up from the RE-ZERO and 0 but a bass monster this is not.  That said the quality is just as you expect, outstanding!  As lightingly fast and agile as you’ll find on a dynamic.  Tight and just super cleanly delivered.  Sure the best BA’s can best it but, and it’s a big but, HiFiMAN have tweaked the 400 to be a little less 0 like.  The 0 when it came out was a dynamic but sounded just like a BA, exactly like a BA and the lacking a sense of fullness in the lows that brings.  The 400 offers a low end that’s that bit fuller and more expansive.  It seems physically larger in the way a multi BA IEM might.  It lets you have a greater sense of feeling the note rather than simply being made aware of it in a cold and lifeless manner.  The 0 while stunningly accurate wasn’t ever one for capturing the soul of a song and bringing it to life.  The RE-400 on the other hand is so much more wonderfully alive in the low end, convincingly vibrant unlike the colourless 0.  Depth here is pretty good too, the spec says down to 15 Hz which should beat human hearing but at that level it’s more about feeling than hearing and the 400 feels right.  The 0’s lack of that, like many BA IEM’s, leaves many to be unsatisfied by that sort of sound without bumping up the audible bass level dramatically.  The 400 introduces a hint of that dynamic fullness. 

So, yes the quality is superb and it’s gloriously full bodied for the linear nature of its sound.  There is still the fact that this can’t roar and rumble like the GR07 can.  The GR07 can thunder out of nowhere, the RE-400 just won’t.  It’s very lively with a fab dynamic range and it can really kick it up for pop music but nothing ever runs away with itself.  The bass is stunning and likes to party but won’t go too far (or as far as some would like.)  It’s still got that seated sense of self control of a truly audiophile product than the wild abandon of a “consumer” orientated product. 

N.B.  For those that have asked about how these compare to the RE-262, I don’t think of them as 2 things id naturally compare as they are aiming for different things.  The 262 is about smooth, lush sound that ever so laid back and relaxed.  The 400 is far more exciting and excitable.  Bass levels are rather more in the 400 too to go along with that hint of consumer type fun.

Mids:  Fabulous is every possible way.  Sure they don’t really come in the creamy liquid lusciousness of the RE-262 but they are so very much more alive than those in the RE-0.  The 0 as I’ve said was stunningly good but a bit soulless.  The 400 is still a bit dry but no more of that thinness.  They feel so very much bigger and dynamically vibrant.  The dynamic range on these is quite stunning btw.  They seem so easy to drive too.  The clarity and openness is faultless.  They are superbly detailed and acoustic guitars snap and twang perfectly.

They may be a bit forward compared to many mainstream things but the mids are spot on linearly balanced to my ears.  That said they seem a little easier to make loud in the upper mids than the lower mids.  The deepest male vocals don’t have the Joie de vivre that the girls manage, most male vocals do too.  That seems a very small quibble though as these are otherwise amazeballs good for this price. (Pretty damn good at any price!)

Highs:  A traditional strength area for dynamic drivers and HiFiMAN.  It’ll come as no surprise to anyone that the highs here are truly excellent.  Hand on heart though I do believe the 0 just beats them but it’s so close who cares, it’s not like anything else for this money can.    They are wonderfully extended and can shimmer and portray a decaying cymbal like little else can.  For all my love of BA drivers and the things they can do the highs they never quite nail like the best dynamics can.  This is one of the best dynamics so long as you feed it quality stuff.  The highs are the first thing to die in compression.  Feed it good stuff and it just shines! Mr Johnson’s “Staple it together” the highs are cleanly recorded and aside from the 0 nothing priced like this is as good. 

The only negative ish is that many who like a trebly IEM are more familiar encountering it in a BA like the ER4 or DBA-02 where the treble has a much more abrasive edge to it.  The RE-400 (and the 0) have a much more natural and rounded edge to cymbal impacts.  Therefore it may not have the same attention grabbing, in your face nature if that’s what you want.

Soundstage:  Pretty good!  It’s not a quality HiFMAN’s stuff is known for but these sound pretty reasonably sized.  Vocals are a still a bit tight in but less so than its predecessor.  Where they stand rather better is in the space and separation.  The lows highs and mids are clearly distinct in their placement and feels like a good sized living room.

Fit:  Well they are teeny tiny and they come with a good range of tips too.  Fit was mostly a case of stick in and done but….. while better than the 0 was there is still a touch of air pressure / venting issues.  In a fairly closed dynamic you always will but on the whole it was fine in daily use.

Comfort:  The things are tiny and weigh hardly anything.  I was utterly happy to wear all day long and not notice them.

Cable:  Hmm it’s a woven cable from the Y splitter on down.  If you’re not careful you could get it to kink but it wasn’t bad.  Above it was just plastic and bit of me finds it disappointing but then I remember what they cost.  It’s very ordinary and functional.

Build:  The buds themselves are superb things, little slabs of what I’m guessing is aluminium. They should survive rather well I think.  The jack, while hardly a looker seems very sturdy and the Y splitter seems very solid too. 

Microphonics:  Erm none really.  None that I noticed anyway.  Of course I did wear them up, even down there really wasn’t much to speak of.

Amped/Unamped:  It held up surprisingly well when unamped given what the 0 was like.  The 0 somewhat famously needed a power station behind it to drive it at its best (I think why the ZERO came out) but the 400 seemed pretty happy running off my phone.  The bass suffered a bit in depth and solidity.  Not that it got what I’d call flabby but it lost that granite like quality it has amped.  The highs too lost their magical uber shiney shimmeryness.  How much of that was due to lack of power verses coming out a so so source who can say.  They still sounding stunningly good but if you supply them with better they will rise to the occasion.  Oh and I rather did like adding additional impedance.  When added it rather refined the already very good highs to nearing the RE-0 level.

Isolation:  Pretty not bad.  It’s a dynamic but it’s fairly closed like all its siblings.  Not trip to New Zealand good perhaps but easily enough for normal usage unless you Tube commute every day.  Certainly enough to get you run over because you didn’t hear that bus coming up behind you if you aren’t looking.

Accessories:  4 pairs of tips which seems like an odd number and some weird cable tidy thing.  The cable tidy thing feels cheap, chavvy and personally I’d never use it.  Ignoring its white it’s just too small and personally I don’t like wrapping cables that lightly.  I’d maybe have liked to see a little case but let’s face it, if you want a little case hit up ebay and pick one.  You aren’t buying this for the accessory package.

Value:  Erm as best as I can tell unbeatable.  For US$100 or £63 (today anyway according to google) I know of nothing as good sounding.  Anyone who is in any way serious enough about audio quality to have read all this really ought to buy a pair right now. 

Conclusion:  While I can accept that these may not be to everyone’s tastes and whatever else but these are pretty flawless.  Okay they don’t isolate like a pair of ER4’s and the don’t have bass like an IE8 or mids like the SE530 or RE-262 and they don’t have the mesmerizingly stupendous treble of the RE-272.  So if you’re the sort of person that wants and indeed expects the moon on I stick then these may not be for you but these are so without failing for the money.  The closest thing I can possibly come to a failing is that they won’t be as bassy as some people are going to want but that’s not the RE-400’s fault but the fault of years of consumer conditioning to the notion more bass = “better.” 

Can not being overly coloured be a failing?

If had been told that these were to cost twice their price it would have still been a favourable review, maybe not such incredible value but on the sound quality there is not much that can best them.  If I’m honest the only real competition I see for these are the GR07 and its sibling, the GR01, both rather more costly.  The 7 is however more of an all-rounder with a more vigorous low end talent so it may appeal to the masses a hair more but it’s practically twice the price!  What’s more staggering is that the 400 still beats it on detail retrieval.  Acoustically the GR01 and the RE-400 are oh so very, very close.  It wouldn’t surprise me one jot if the engineers at HiFiMAN had been listening to the GR01.  The differences are the GR01 isn’t as extended in the highs as the 400 but it obviously isolates rather more.  So very, very similar sound signatures but the RE-400 is somewhat more dynamic sounding.  As in acoustically dynamic not BA / dynamic.

The 400 is really up there with pretty much the best you can find regardless of price.  Sure it’s not quite top tier stuff, nether was the 0 but its close enough you won’t care.  Frankly at its current US$100 it’s an utter steal.  For what is practically no money in audiophile terms these offer genuine talent that is for all intents, practically perfect.  Anyone with audiophile aspirations ought to have one of these and could legitimately only have one of these.

Yes, really it’s that good.

HiFiMAN RE-400 Quick Review

HiFiMAN RE-400 Quick Review

Thanks to Head Direct for the sample.

Brief:  HiFiMAN’s stunning RE-0 replacement

Price:  US$100 or £63.50 at today’s exchange rate.

Specification:  Driver: 8.5mm, Impedance: 32  OHM+/- 3.2, Sensitivity: 102dB/1mW, Rated power: 10mW, Maximum power: 30 mW, Frequency response: 15 ~22 KHZ

Accessories:  4 pairs of tips and a cable tidy thing.

Build Quality:  Pretty good, woven cable cover if you like that sort of thing.

Isolation:  Fairly good.  Fine for normal day to day stuff easily but not really flight to New Zealand good.  Still enough to get you run over of course.

Comfort/Fit:  Comfort was great, fit was a bit more sensitive as they did give me a bit of venting / air pressure issues.  Nothing major but pretty closed dynamics always have a bit of that.

Aesthetics:  The buds look not bad with their sculpted metal exterior.  Visually though these are nothing stunning.

Sound:  Exquisite.  The old RE-0 were stunning, unrivalled at their price and I don’t think anyone has ever claimed otherwise.  Their only problem was they were very narrow and unfulfilling in the low end.  The RE-400 fixes those issues while retaining essentially the same stunning, jaw dropping clarity at a price that no one else can touch.  Sure it’s still going to be rather uncoloured a sound for some.  It can’t rumble and roar in the low end and compared to mainstream stuff the mids will feel very in your face.  It also not the greatest at doing laid back and smooth.  It’s a real wonder though, clarity, detail, superb shimming highs are all fantastic.  It’s pretty uncoloured not unlike it predecessor but aside from a slight loss of treble detail these are just as articulate.  Very balanced on the whole, a tiny bump up in the low end, mostly the improvement is in the sound staging.  It’s a real step up from the 0 and makes the 400 sound much more full and sizeable.  The dynamics are outstanding too making for a rather lively, energetic sound that can really fade to a whisper then get very loud in an instant.  It’s a practically faultless sounding IEM that is just full of vim and tremendous balance.

Value:  Arguably the best value of any IEM ever in my opinion right now.

Pro’s:   Insanely good sounding.  Superb detail levels.

Con’s:  Has not the “consumer” levels of bass some might want.

Frogbeats C3 Customs Review

Frogbeats C3 Customs Review

Thanks to Frogbeats for the sample




(A small shout out to http://www.betterhearingscotia.co.uk/ where I had my ear impressions made.  It was really quick, easy and I remember at the time thinking rather cheap too, although I now can’t remember how much it was.)

First Impressions:  It has been with some anticipation that I have been awaiting these.  What feels like many, many moons ago I got to demo all the various options Frogbeats had in their universal form.  They were wildly ungainly things and hideous to boot, not just that they were so hard to get them sitting right that once you did you near dare not breathe for fear of moving.  Now I knew that would not be an issue with the final product but still, as my first set of customs it did cross my mind that perhaps the fit wouldn’t be great or that the acoustic changes that would happen would make the ones that I heard before sound nothing like what the final product would be.  What if I had lead Frogbeats down the wrong path and into some hideous disaster?  So the box then, as it sat before me seemed so unassuming, sans the card sleeve the little blue box, okay maybe not that little blue box.  Inside there they are, they look good.  I had requested they be coloured, red for the right one and blue for the left.  They look just the colours I wanted so that’s certainly a good start.  I know looks aren’t really that important but even as the baby of Frogbeats present offerings at £490 they are hardly cheap so it’s very nice to know that these look spot on.




Sticking them in my ears for the first time, which was a little weird I must say, sort of angling and twisting them then they just slipped in.  It was a curious sensation, I may be very used to sticking soft squishy thing in my ears but this was quite different.  There was no give, there was no adjusting angle or depth.  It wasn’t unpleasant just very different than what I was used to.  Slapping on some music and what struck me most was the bass, the bass was not only very significantly sized but seemed to have terrifying depth.  For something that only has one BA bass driver in there it’s doing a remarkable job.  I don’t feel the bass like a big dynamic but it sounds like loads of air is being moved.  Maybe that’s what you get with incompressible acrylic rather than soft squishy foam?  It’s all very curious.  Burn in time.

Lows:  They have depth, depth that I’ve heard no universal with.  In paper they shouldn’t stand much above things like the Westone W4 which has the same on paper spec, down to 10Hz.  This feels as though it just takes that midbass level that is so easy to do and just takes it all the way down, no fuss or straining it just does it.  The acoustic measurements I’m sure will show the bass as being rather boosted and that’s because it is.  The C3 was never meant to be about going for an on paper spec, let’s do something flat, it was I think always for more concerned with having a party.  The bass therefore was likely to play a leading role in the C3 and the C5.  Now in the old universal fit that demoed so long ago the depth didn’t feel it was all that one might have hoped it to be but it was assured that the real deal with a proper seal makes a big difference and boy there weren’t kidding!  After all the years of multi BA IEM’s using two for the lows and one for everything else you could easily be forgiven for thinking that using just one in the lows might leave them lacking, however it does not.  I haven’t heard the C5 and I don’t doubt that it will be better but it no way means things lack here.  They are thick, weighty and lusciously rich sounding.  One of my Favourite albums Erasure’s Union Street (I know its Erasure but trust me hear it before you judge me) and it sounds so deliciously rich and mellow.  The midbassy combination of the very rich vocals and the slow lumbering lows that abound in the album are the acoustic equivalent to a gooey chocolate pudding. Dark, enveloping, viscous sumptuousness that just melts and flows over the senses.  Its just as that album yeans to be portrayed with the weightiest of lingering notes and the C3 are doing a quite mesmerising job of it.

Moving on to faster and more agile bass and I’m going with “I Turn To You” which I stumbled across but I fear isn’t really all that fast.  It was the Hex Hector remix but dance type music isn’t my sort of thing.  I had slightly feared that the richness and ever so laidback attitude would mean fast would be a problem.  It wasn’t.  The low end has all the agility one would expect of a BA, by that I mean it flies like a rocket on steroids.  I’m not sure this is really what I want as I personally like that as bass rises in quantity the usual thing is that it slows and softens.  Here I feel the low end is hurling itself like a race car cornering, I can’t fault its ability but with the perfect air tight seal of a custom and the bass level I sometimes found myself wanting a little softness.  It could also be that I’m subjecting myself to lots of fast and bassy music which is not my favourite sort. 




Mids:  I love mids and a really am very happy to have them out in front, the sort of stuff I prefer musically suits that sort of thing well.  The mids here are not out in front and are a touch recessed.  They sit on the liquid and rich side of things too and I may have preferred a teeny touch more air about them but what I cannot fault is the detail level.  For something of a liquid nature such as this the detail retrieval is just outstanding, it really is first rate and as I sit and AB with my mids benchmark, the SE530, they sound so much fuller.  They do it so differently, the 530 sticks things right up in your face but the C3 is so much more relaxed about the whole affair.  The detail and nuances are there if sir should care to peruse what’s on offer.  It’s there so effortlessly and casually displayed.  They two styles are so very different, and I’ll admit right now I prefer the 530’s approach. 

That I’ve just said I prefer the upfront mids approach I’m now going to utterly contradict myself, or at least seem to.  Nora Jones is a fabulous artist and her rich, gooey, melodic voice is perfectly suited to the rich and liquid mids of the C3 and the 530 but the 530 sticks her out in front and the C3, well it has her casually strewn across a chaise longue, slowly swirling a glass of Glayva (not sure if you can get it much outside the UK, it’s a whisky liquor and is ever so pleasant on the tongue.)  It’s probably easiest if you just buy a buy a bottle, stick Nora on and I’m sure you’ll get a good idea of what I mean.  Vocally she just oozes delicately and effortlessly, smooth and sultry and it is just wondrous. 

Shifting to something more dry, The Bird and the Bee’s “Ray Gun” has not quite the openness and airy quality that I’d hope but the level of detail there pulls out so much more than I’d have expected.  The thickness that the C3 has and gives everything such body and weight should suffocate any air it finds but it doesn’t, the level of detail it offers ensures that some remains and allows you to hear that it’s a dry, airy song.  It’s peculiar.




Highs:  I find that these have a bit of a V shape and as such the highs are rather abundant.  Ooooh yes, abundant treble so for me that’s like waving a red rag at an angry bull.  Its almost daring me to pick fault and so I shall.  The quantity isn’t for me, it’s too much and I don’t like it.  That of course is an entirely subjective perspective and one that’s not likely to be shared by everyone or indeed by that many.  I was only the other day thinking that the IE7 is indeed one of my favourite IEM’s yet its treble is often found lacking by many.  I don’t like a lot of treble, so sue me.  I have sensitive ears and they are particularly sensitive to treble.  I can hear high and with the state of modern music such as it is where things are dynamically compressed to death the first thing to suffer is the high end.  Recently I’ve been acquainted with the band Nightwish and their album “Imaginagium.”  I really rather like the album but my god, I’d like to take who ever mastered it and beat them with a pointy stick!!!  The highs as oh so effortlessly offered up by the C3’s show you just how the highs were produced in this album.  I’m convinced they just recorded someone going “spssssshhhhhh ssspppssssshhhh” over and over again. 

This is the trouble with the high end here.  Its sufficiently able and abundant that it does utterly no favours to sucky recordings and sucky mastering.  You can hear all that’s there and Nightwish, shame on you!

Another thing, and again its not really its fault, is that it can go high, high enough that it will show up easily hiss in a track, “Somebody That I Used To Know” becomes so frustrating and distracting as to make the song practically unlistenable.  I can’t stop myself from picking out all the crap that’s going on the in the background and what is with the hiss!?!?!?  The C3 has so little trouble picking out details that you would rather you didn’t notice.  If you want a sure fire way to ruin lots of modern songs then this level of clarity and detail retrieval is a great way to do it. 

Enough with the negative, all not the C3’s fault I might add, so what does it do well?  For a BA it has a near dynamic ability in shimmering.  They don’t have the brutally crisp edge that is so common in trebly BA IEM’s.  Listening to Mr Johnson’s “Breakdown” and once the cymbal kicks in it is very convincing.  The impact is cleanly crisp and the shimmering decay that ensues is I believe the best I’ve come across from a BA.  It’s not easy to do and I find myself being more than impressed with ability to just get on with things and making even the hardest things feel effortless.




Soundstage:  Grand, expansive and with a great sense of depth and scale.  The down side to this is that it never really seemed to want to get up close and personal.  It feels like being in a sizeable but closed room, yes there is space but its finite and lacks a truly open airy feel that I might have liked a bit more of.  That of course the C3 is sealed, vacuumed sealed means that’s hardly a shocker.  The clarity though can make for a relatively intimate impression on certain songs, like it’s just you and Nora in a room but she’s strewn over a sofa in front of you rather than being right in your face.

Comfort:  These are the first customs I’ve used and they are rather different to what I’m used to.  Now I’ve heard millions of IEM’s but they all don’t give you the same feel as these do.  These seal perfectly.  The absolute seal made the bass capable of its quite amazing depth, far exceeding that of anything open I’ve heard.  In my ears, the having something sit quite deep and being so unyielding was a little strange.  Particularly the perfect seal I found took a little getting used to.  It wasn’t uncomfortable but it was odd.




Fit:  Being custom moulded they ought to fit you perfectly it take a little twisting to seat them though, then being hard acrylic.

Cable:  Very good.  It’s tightly braided and accordingly is very flexible yet seems rather sturdy.  The cable is replaceable anyway so if you don’t like it you have that option.

Microphonics:  None really, well a bit of foot fall coming through but certainly nothing from the cable.

Accessories:  The stand out is no tips!!!  So numerically rather light but they come with a case.  While it’s not something you’ll slip into your pocket it looks and feels pretty indestructible.  Short of deliberately taking an axe to it or driving a car over it I can’t see how you’d kill them in this thing.




Amped/Unamped:  Here’s a shocker, unamped they still sounded really good.  Now I know my little Shuffle is quite potent but still it’s nothing too special.  It managed to drive the C3’s fine.  Now of course when you moved up to something rather better they made full use of all you could give it.  I cannot ignore though just how well they did with my phones.  They were rather noticeably different between the two phones (Galaxy Nexus and Sensation XE.) the mids on the Sensation were so much more focused and forward with the GN being more flat and slightly more detailed.  Of the two the GN impressed me more but both made the C3’s sound very, very good.  I must say it got me thinking maybe Frogbeats might be persuaded to offer a cable with a mic.  Not that it’s really doing them justice to do so but I was pretty taken back on how well the GN drives them.  I think you could legitimately use the two together and get away with it.  Maybe not all you’d ever use to drive them but I’m just saying you could.  The only trouble with this is that lesser sources, the shuffle, the phones tend to be a bit noisy.  If hiss drives you nuts then, well maybe it’s not for you as the C3 hides nothing.

Reality is though if you’re buying these then you’re probably using something pretty good.  Feed them good and will show.  Out of the Studio V 3^rd and the FiiO E9 they were at their noticeably best.




Value:  It’s always a tricky thing to judge value, not least of which because what is there to compare these to?  As I mentioned before these are my first customs so right of the bat I can’t compare these to any other customs regardless of pricing.  What I do have is a bunch of high end universals.  Grabbing what are off the top of my head the most expensive ones (CK10, TF10, SE530, W4 and the IE8) and the difference becomes quite apparent.  The CK10 especially sounds so needle thin.  Of them all only the IE8 comes close to sounding as rich and full as the C3 and even then it can’t hope to compete with the depth.  The IE8 is really rather open and while having great bass the depth isn’t there like the sealed C3 can do.  I’ve never really been wild about the idea of customs over universals as I really wasn’t convinced they could be all that different.  After all the W4 has 4 drivers in there so there is no obvious gain from moving to the larger enclosures found in customs.  The reality is there is, most notably in the low end where the depth is very clearly superior.  The universals I have here just cannot compete.  So while there is a chuck of price difference, as the C3 are still pretty expensive objects when most people think spending £20 on earphones is a lot of money.  To spend £490 on a pair then is a fairly rarefied crowd and I’m not going to suggest that it’s the wisest thing a person could do with the money but……… a check on Amazon UK has the W4 coming in at £360.  These are simply better, sure they aren’t flat monitors like the W4 but in all other regards they are simply better.  The sound signature too is likely to be a more popular one than that of the W4.  I’m not sure I’d place the C3 as being better value than most high end IEM’s as diminishing returns and all that but it’s pretty apparent you get something clearly superior sounding.




Conclusion:  I had a touch of up and down with these.  When I first got them I had some fit bother and then the worst of timing, I hurt my ear so these sat for some weeks untouched.  Once my ear was no longer in pain I gave them another try and realised that the fit wasn’t just quite right on the right hand side.  They then got to take a trip back the land of their creation.  This as you can imagine took a little bit of time and naturally we had Christmas and new year in there too.  By the time they came back I’d mostly forgotten how they sounded.

When I restarted listening to them I recalled their sound signature and its unassuming nature.  It at first seems nothing special, it has this smoothness and above all effortlessness to it that doesn’t grab your attention.  Some IEM’s, the DBA-02 springs to mind, hurls the treble at you with such wild energy it makes you feel they are amazingly revealing.  Now I’m not saying they suck because they don’t but they trick you somewhat.  It’s like turning the brightness and contrast up to max on your TV.  Everything will look hyper crisp and pop out at you but it won’t actually make the recording itself any better.  I love the old “Walking With….” Series from the BBC.  Dinosaurs and Monsters are both great and I love them but they were made so long ago, they are old PAL 540 x 480 lines and if you compare it to something like the BBC’s “South Pacific”  which is in many ways a lot of rubbish (Hawaii is not in the fcuking SOUTH pacific!)  Visually however that thing is just stunning, just amazing visuals on that programme.  Once you have something of that quality you don’t need to over dramatise things.  You can allow the quality to come thorough just as it is in real life.  No artificial additions or adjustments to make things pop out more.  This is how I’m feeling about the C3 despite its somewhat V shaped sound.




The C3 is subversive.  It as a V shaped slightly dramatic shaped sound yet it does not feel dramatic.  The only universal that I can think of that in anyway comes close in the IE8 but it’s not the same.  The IE8 was clearly a bit of a rollercoaster but it did manage to offer up astonishing clarity in a most unassuming manner.  So much was there but unlike that of an ER4 or DBA-02 where it was thrust at you the IE8 was in comparison almost hiding it.  Things were all there they just didn’t leap out at you with over contrasted edges and this is very much like the C3.  When you listen to them on their own they are so unassuming.  Sure they sound like the have tremendous scale but the nuances are so gently and casually displayed.  It isn’t until you start paying attention to old songs you know very well and you start hearing things you haven’t really noticed before.  That tambourine in there somewhere, that slight echo in the vocals, the over tough fingers sliding along a guitar string.  Things that when you hear them seem so natural and casually placed that you may just ignore them but if you are paying attention, you realise you didn’t know they had been there.




The detail level that the C3 actually give is out and out amazing but you have to pay attention or it shall pass you by.  Even the mighty RE-272 can’t match the level of detail and might I add the 272 sound razor thin in comparison.  Even the body of the IE8 can’t compare, it’s the closest I’ve got in an IEM but it hasn’t the endless depth and the C3 just sounds bigger.  Bigger, richer, more full bodied and endlessly powerful.  This is really what I’m taking away from the C3 is that it seems to have so much power and scale that everything seems so effortlessly presented.  All in all it’s a thoroughly impressive sound that to date tops any universal IEM I’ve listened to, and it’s been a few!

Isolation:  Shed loads.  Hard to say if it’s quite at ER4 levels as it’s hard to gauge external sounds with either in.  In short there’s tons and I’d have no trouble saying these would do you well on a daily Tube commute or long distance flight.  You will not hear road noise so be warned, look where you’re going!

Comfort/Fit:  Good.  I must confess I still find them somewhat peculiar in the ear compared to universal IEM’s.  It’s not uncomfortable in anyway it’s just not what I’m used to and weird.  It does take a little bit of a wiggle to get them in but one done that’s them.

Aesthetics:  How they look will largely be determined by what options you pic, I went with one all red and one all blue so nothing too elaborate.  You can if you want even pick custom colours so how they look is up to you but I like what I have here.

Sound:  Effortless.  They sound so vast, so powerful and with body unlike I’ve heard from an IEM.  Their sound signature is rather V shaped with the bass in particular being quite potent.  It’s elevated in quantity but has excellent depth for a BA, it’s rather more dynamic like in every way.  Of course it’s not a dynamic so it’s still very controlled and agile when required.  Mids are a touch recessed and rather liquid but wonderfully clear and detailed.  Highs are a bit forward but great for a BA, not over crispy.  It can really have a good go at real shimmer and delicate fading away too.  In many ways its sound reminds me lots of the Senn IE8, just improved particularly in bass depth.  It’s such a robust and full sound yet the detail is fantastic.  It may not hurl it at you like the RE-272 but there is vast detail retrieval if you listen for it.  Either way this is more about enjoying the music than it analysing it.

Value:  £490 is the starting point depending on your options and that’s quite a bit of cash.  Customs are not cheap and seeing as these soundly beat the W4 which cost almost as much you could argue you’re getting a bargain!

Pro’s:   Huge, powerful and effortless sound, great bass, great detail.

Con’s:  Have a definite flavour, if you want flat this is not it.
