HIFIMAN RE800 Earphone Review by mark2410
Disclaimer:  I work with HFIMAN so feel free not to believe me if you so wish.
First Impressions:  Well this isn’t really my “first” impression.  It 
technically is with an actual retail set but…. Well yeah that working 
with bit I mentioned.  I’ve been playing with these for basically the 
last 6 months and unsurprisingly, I like them.  I like them rather a 
lot.  Okay so I’ve liked every IEM from HIFIMAN I’ve ever heard so this 
is not likely news to anyone.  These are in keeping with the RE262 – 
RE600 vein and it matches up more or less perfectly with my personal 
tastes.  They are bit warm, bit bass boosted, bit middy and a little 
gently sloped in the highs.  So if you’re a treble junky these may not 
be for you but…….. for me and for all day listening.  FCUK yeah!!!  So 
easy on the ear the RE800 is like they took the RE600, dipped it in 
magic sauce then sprinkled pixie dust on it.  Particularly with the big 
Comply’s on, it further just dampens the treble for my treble sensitive 
ears yet has hidden depths of resolution in there.  It’s so nonchalant, 
casually presented which is just how I like it.  If I want to listen out
 for micro details I can, or I can stop and just listen to the big 
picture, the entire grandiosity of it all.  Oh and if you were in doubt,
 they do a glorious rendition of cello’s.  There will be much Elgar this
 coming week.

Lows:  Well its rather glorious.   The natural thing I’m going to 
compare it to is its sibling, the RE600.  The 600 was a tweaked 
evolution form the RE262 and thus when you first hear the 800 its seems 
in the same vein.  It is, sort of, it feels like the natural next step 
up and then you stick the 600 in your ears and wonder what happened.  
The 600 sounds so nasal and mid focused, no breadth, no spaciously open 
smoothly rich low end.  The deepest reaches are a bit boosted yeah but 
it seems to cling on a with a ruthless yet utterly natural feeling 
tenacity.  I mentally get its boosted. I know it is but to know what’s 
in a lasagne you look at the ingredients list but it doesn’t in any way 
describe what the combined sensation is like in your mouth.  These, they
 do that but in your ears.  These are good in such a 
non-attention-grabbing fashion, they lull you into it ever so smoothly. 
 While I’ve been playing with these for about the last 6 months which is
 dramatically longer than I usually spend with an item to review.   
These are so sumptuous and controlled like some hyper control freak yet 
like a swan effortlessly and gracefully gliding across a lake, its 
melodiousness is pure perfection.
Kicking into artificial bass lines like those form Enya, “Even in The 
Shadows” to “The First of Autumn” they just grip on to the note so 
incredibly tightly yet go with it in perfect sync, like some perfectly 
synchronised figure skating.  They sweep, they swoon, they shrink to 
almost nothing then they roar and thunder.  “Your Father And I” comes 
barrelling out at you like a force of nature, you can practically touch 
the articulation of the notes.  These remind in me in same ways of a 
well amped and impedance added IE8 yet when I try the IE8’s they feel 
so, grey.  That spark has gone, the clarity has fuzzied and they just 
feel like a lesser product.  Mars the bringer of war, seems more like 
Mars the bringer of slightly unhappy but can’t be bothered.  The lows 
are just so vague, soft and flabby in comparison and those are not 
things the Senn is normally thought of as, but side by side it is.  The 
RE800 takes what was once thought of as the best by far, single dynamic 
IEM and solidly spanks them.
The quantity, while so far these may have been coming across as a bass 
monster but they are so not.  Not only because they so clean in their 
articulations but that they are not really that bass boosted.  Sure they
 are bit, these are in the RE262>RE600 line, not the RE0>RE272 
more neutral line.  These are not strictly ruler flat, but what is, 
still the bass, is boosted but not ever present like on the IE8 which is
 my go too bass IEM.  It does tail off in the furthest depths but that’s
 really what should happen.  It’s the natural timbre of it all.  The 
lower end ranges of a cello and into that of a double bass, I can 
practically touch the strings.  Good god they feel so alive and natural 
for an IEM.  It’s so unspeakably nuanced for an IEM.  This is more 
heading in the direction of an open backed headphone and yet unlike the 
IE8 and IE7 they haven’t done it at the expense of giving sod all 
isolation.
 
Mids:  Taking those low cello notes and going the other way, well, if 
you like a cello (and I do) then these are not just good but 
breath-taking.  Not so mid focused as the 600 is, the sound staging here
 takes on a breadth but doesn’t then layer on breathy dry, stripping any
 liquidity away from it.  Elgar and his cello concerto is just 
magnificent.  It really is the way these can move from the simple and 
humble, focus on a delicate and almost trembling solitary cello.  So 
meek and unprepossessing, then it symphonically rises up and becomes 
this staggeringly full bodied cacophony of power.  I know part of the 
intention in the creation of these was to give the listener a 
presentation that aims toward that you might find, sat in a concert hall
 and…….. while a big open can can do that semblance of authority and 
majesty better…… these are tiny itty bitty things which fit in your ear.
The flavour of the mid-range means that it’s not so focused and in your 
face.  Moving to a broader spatial presentation they are a smidge of 
distance back and lack that dash of extra fluidity I like.  Vocals 
aren’t as smooth and creamy as I often like but these feel more 
realistic.  I know I like things a little too creamy and buttery and 
while these give the impression they might go that way they never quite 
do.  You see doing that starts to obfuscate their clarity and they can’t
 bring themselves to do so.  The clarity and natural timbre, while I 
hate the term “organic” they do have that feel.  There is something 
real, non-artificial, might I say, no artificial sweeteners.  Both male 
and girly vocals are so persuasive.  Tracy Chapman feels like you’re in 
the studio with her.  Everything so clear, natural sounding, every 
inflection, every note, that sadly mournful, yet clinging to that last 
lingering ounce of hope for the future.  So emotively alive and real.
In strict quantity terms, they aren’t as mid stand out as most other 
reference type products, these have nudged the bass up a smidge and the 
mids are only a teeny bit.  Just the slightest of nudges yet they have 
so much clarity and detail that I don’t care.  Vocals aren’t that Shure 
like, hyper fluid and smooth like, better than the actually vocalist 
sort.  These are aimed at a natural reproduction, tone, body, air and 
breathy nuance.  Be it Barbara’s “Papa Can You Hear Me” or Michael 
Ball’s “Tell me There’s a Heaven”  Or Barbara’s “Send In The Clown’s” 
good lord that woman can sing, these do her so well.  Either belting a 
note out or as softly delicate as you can imagine.  There is a reason 
these have been the IEM I’ve been using most days for the last 6 months.
  They do all the things I care about supremely well.
Highs:  So if there could be anywhere these may not find fans it could 
be here.  These are not bright, in your face and if you wanted a new 
RE272 you’re not getting it here.  Flicking back and forth they haven’t 
that, “neutral” treble, it is like the old 0 , being ever so gently 
tapered off.  While this may not make for the most sparkling 
presentation its one that is so easy on the ear.  Again, there is a 
reason this has been my default thing to pick up for the last 6 months. 
 These are not the most wild of trebles, its’s tamed, its nudged gently 
in the direction of polite.  The detail levels it can do are every bit 
as good as the RE272 ever was and these actually surpass it if you 
listen close and have the right pairing.  These are very VERY detailed 
but it’s not in your face detail.  So much so that you can completely 
get away with so so recordings.  I don’t know about you but a lot of the
 music I like is not well made, mastered or recorded and here I can 
enjoy the finest of recordings and still like the badly made stuff.
The treble though isn’t all completely forgiving, due to the thing being
 so very VERY highly detailed it means that it’s got the clarity and 
speed to hit notes hard.  You feed it a hard-edgy treble, looking at you
 Owl City, and it will impact hard, a little too hard my ears.  I mean I
 can’t fault the RE800 for accurately playing back what they are being 
fed but…. This is the danger with super high-end audio stuff, you find 
music you like isn’t well made so once or twice I was tracking skipping I
 liked on lesser things because it was just to clean and hard edged.  
The actual quality is when you find some really fine recordings which 
unfortunately all seem to be classical the mellitic clash of a cymbal 
comes across with a refinement and natural delicacy to it that is 
unspeakably real.  It is superb and comes the closest in an IEM to truly
 being real yet it’s hard to focus on it alone.  The coherency you get 
from this being a single dynamic means everything is so well integrated 
nothing artificially stands on its own.  Great for listening to, a pain 
in the behind for reviewing and even more so given the lack of superbly 
recorded treble happy music.  Still the Chesky demo disc with “sweet 
Georgia Brown” has a morass of treble notes all splashing in from every 
direction and its hugely impressive.  The detail and refinement these 
display is so great and yet so casually presented it really isn’t until 
you go back to something lesser that you fully apricate the difference.
Soundstage:  It like the treble seems so natural, so beguiling, it’s 
just sort of there and you don’t really have the typical awareness of 
the tiny speakers in your ears that most do.  Even whipping out those 
IE8’s which were once spoken of as a miraculous achievement in terms of 
their soundstage and the vastness of it.  These don’t feel huge, they 
just don’t but they don’t feel enclosed.  They capture that quality the 
RE252 had and I never felt I could really quite describe.  The audio 
seems to come into existence rather be “created” just a fraction of an 
inch from your ear drum.  It is somehow magically just present as though
 it had happened though some space/time portal.  I realise it doesn’t 
really quite make sense as a description but if I could find the words 
I’d use them.  There is a quality whereby things just are, not enclosed,
 not distance, things just are.  It’s a very “natural” sound like 
listening to the real thing but coming form an IEM, I can’t help but 
feel it to be a peculiar sensation.
Comfort:  Great.  Nothing particularly notable or eventful about them.  
They are round, universal in ear things like many others and I could 
wear them happily up or down and for many hours at a time with no 
problems.  A little more bulbous than the 600 before it so a bit bigger 
but I never had any issues in the slightest.
Fit:  Super, shoved in ears and was done.  Given its me I went right to 
the included Comply’s because when reviewing find silicon’s just give 
that little bit of suction when removing.   These are vented so I 
wouldn’t expect anyone to have any real issues with them.
Cable:  Well….. its actually pretty nice.  It’s not blowing me away but 
it’s back to the kind that were on the RE2x2 range and not, the clothe 
weave ones from the RE0 and 400 and 600.  While I know that cable on 
them was selected for its acoustic properties and yes they did sound 
great but……I still never liked the feel of them.  This however is, I 
think, a considerable improvement.  Its rubbery coated and feels very 
flexible though I do strangely like the metal Y splitter and the chin 
slider, while I’m sure a plastic one would have done the job just as 
well, I like that it, the jack and the buds are all matching metal.
Microphonics:  Worn up none.  If you insist on wearing down then yeah 
there was a little but the cable does a pretty good job of absorbing the
 vibrations and you can use the chin slider to remove the issue entirely
 if you want.
Aesthetics:  Well, on the whole I like but….. I’m not wild about the 
gold.  I’ve never been keen on gold and if I’m super honest, I’d rather 
they were just plain brass as there would be a certain honesty and 
purity in that.  Mind you I’m hoping that we might see some limited 
editions in the future with more colours, not that the colour really 
matters but you know.  Yet weirdly while I don’t love the gold buds I 
rather like the golden Y splitter and chin slider, maybe it’s that they 
are next to the black cable?  It least it’s all a matte, sand blasted 
gold finish so it’s not super shiny.
Accessories:  You get the standard, bunch of tips which now includes 
some Comply’s so yey! Then you get the little plain black case and less 
commonly, some ear guide things, if you like that sort of thing.  I 
don’t use the guides but I’m pleased to see them included as it always 
pains me when I see people using a high quality IEM and then are just 
wearing them straight down.
Amped/Unamped:  They do have an impedance of 60 ohms so, don’t expect 
any old thing to do super amazing things with them but…..my itty bitty 
1G Ipod Shuffles actually sounded bloody good driving them.  The hiss of
 the Shuffle got in my a face a couple times with the brighter tonality 
and more brittle nature of it, it made tracks that were hissy, seem 
extremely so.  Still, for a thing so ancient it did a hugely fun attempt
 at high end audio.  Seriously, the slightly warm slant of the 800 took 
on a liveliness that really worked for mainstream pop music.  Dancing in
 your chair, mouthing along to the words, it really was impressively and
 surprisingly fun a combination.  Not the most grown up pairing 
obviously.  Flicking to the Pixel and…. Well the background was much 
blacker and arguably of a more mature tonality and style.  While it was 
really very very listenable for a phone I don’t see me retiring separate
 DAP/s anytime soon.  Still the impedance rating really wasn’t the 
nightmare it could have been, not having a crossover in it meant there 
wasn’t any wild swings (cough Westone, cough) in their tonal balance.  
Ditto with adding the Ety impedance adapter, which you know I love to 
do.  That that pushes the impedance super high for an IEM, so your phone
 or so so DAP wont probably like it if you do.
Isolation:  Well in most regards these are hitting it out of the park by
 most IEM standards but…. These are dynamics and they are vented.  Only a
 little bit vented so while for a dynamic their isolation is actually 
really good but it still won’t hold a candle to a pair of deep seating 
BA IEM’s.  It is the same argument you get with headphones, open vs 
closed.  Open has generally considerably superior properties but they 
don’t block out anything so they are not as useful in all situations.  
While its less extreme as these do isolate pretty well and I have been 
absolutely using them on a bus and on flights, if I had a daily Tube 
commute, probably not so much.
Build Quality:  If there is an area where HIFIMAN traditionally gets 
flack, it’s the build, okay specifically the cables on the 400 and 600. 
 They rubbed many people the wrong way and while year they sounded 
great, I for one shall not be mourning the loss of that cloth weave on 
the outside.  I’ve had no issues so far and I do like the jack.  The 
jack is big and beefy that you will maybe want to keep away from your 
phones screen.  I like it though, big chunky beast of a thing.  Still 
the main improvement is the cable, it feels so much better in the hand 
than the one on the v1 RE600 and 400.
Value:  Well let’s face it, at this price we are into diminishing 
returns and these are not 20 times better than the RE00.  However, 
nothing is, a Ferrari isn’t 20 times better than a Ford but if you go to
 a Ferrari show room and your thinking about which is the best “value 
for money” you have totally missed the point.  If you want the highest 
reaches of performance, then you had best prepare your wallet for a 
beating.  You know, while US$699 is a fair chunk of change, in terms of 
speakers it’s a drop in the ocean so you could say these are super 
awesome amazing value compared to what you’d pay to get this level of 
audio quality in a speaker set up.  To date, these are, I think, my 
favourite IEM out there.  If ever was there an IEM made especially for 
me and my ears, it is basically this.
Conclusion:  Right off the bat I can state with no equivocation that 
these are a magnificent work of acoustic art.  I know bits of their 
design and construction and I realise that saying, oh we painted 
patterns on the driver sounds like, big deal, so what.  However, it 
really actually is a monumental step away from what the industry has 
been doing for years.  Instead of making diagrams ever stiffer to combat
 deformation and ripples HIFIMAN has said, okay so it’s impossible so 
let’s aim to control them instead.  This is not unlike is attempted in 
BMR (Balanced Mode Radiator) speakers and despite being on teeny little 
IEM drivers, it works.  Holy crap does it work too.  It sounds like such
 a simple little thing, I mean how much distortion could there be on the
 driver anyway right?
The tonal balance on these and the purity with which they are capable is
 a real feat of engineering, sure they are a hint warmed so treble 
junkies or those with high end hearing loss may want something more 
bright but good lord, sooooo much detail.  If anything, these are well 
into the territory whereby the biggest problem they face is showing up 
flaws you don’t want to hear.  So much music isn’t well made and while 
these are trying to be forgiving and not thrusting it in your face…… its
 so easy to notice if you have a keen ear.  I did find that some tracks I
 just had to skip because they just aren’t well made and the 800 
presents it all so cleanly its completely noticeable.  It may not count 
as the worst flaw ever but it is a problem.  However, once the music 
industry, as happened with TV when HD came in, they will begin to tidy 
up background rubbish that shouldn’t be there.
So would I buy a pair?  Well my wallet wouldn’t be thrilled but these 
are about as close to what I would make for me if I was making an IEM.  
The tonal purity, the clarity they are capable of, the expressiveness 
that strings and and brass instruments can portray is sublime.  You can 
auraly melt into everything, not just hearing music but it speaking 
directly to your soul, washing over and through your senses.  They are 
so accurate and detailed yet have zero coherency or timing issues which 
you tend to get with crossovers and multi driver setups.  The more 
drivers, the harder it gets and with some things now having 14 drivers 
per ear, the scope there for anyone thing being just even the most tiny 
of hints out smears the audio.  A single driver means none of that takes
 place and no crossover where either drivers have to work over each 
other, smearing as their performance will never be perfectly the same, 
or you dip them so they don’t shout over each other.  Sure some 
multi-drivers are still awesome but I’ve not met one that sounds so 
completely integrated sonically.
In short, the RE800 is a masterpiece of engineering and of audio art.  
It won’t be all things to all men but I would very much doubt that 
anyone who listens to one won’t give it the praise and respect it 
commands.  There is so far, in my opinion, no finer audiophile IEM.  
Timing, coherence, tonality, timbre are all as fine as its sounds 
signature is sublime and beautiful.
