Summary: i totally would like to believe that there is no earphone brand as admired as hifiman , at least admired by purists , and the small and cute re-400 is not an exception , its a total value phone and all every penny is best invested .
yes these phones lack some sub bass and dont hit big like a bass phone cuz its nothing close to it , it is more of a mid centric phone and is as balanced as i wish , now im not a fan of booming bass so i like re-400 more than S5 or ckx-9 ,...
Pros: bass decay , speed , details , clarity , instruments separation , top end spark , nice cable .
Cons: some veiling in the mids , bad cable clip , if that is a thing .
Summary: HiFiMAN RE-400 Waterline - Ultimate Review w/ pictures
1)Equipment and cabling
HiFiMAN RE-400 Waterline
Type: Closed, tiny, in-ear, dynamic driver monitor
Frequency response: 15 - 22.000 Hz
Impedance: 32 Ω (may vary by up to 10%)
Efficiency: 102 dB
Weight: 16 g (with cable)
This was my first in-ear-monitor purchase. Also the very first IEM made by HiFiMAN. Their cheapest headphone yet, priced at 100 USD. How will these compare?
Pros: smooth sound, good detail retrieval, forward midrange, tight bass, extended smooth highs, excellent imaging and separation, decent soundstage width
Cons: bass a bit soft in punch at times, initial build quality
Summary: After I bought the HD 598s, I was soon looking for a portable set of headphones or IEMs for casual use on the bus or outside. Sure enough, I found the lauded HifiMAN RE-400 to be an interesting option and even with concerns of durability and the possibility that a neutral sound signature wasn't for me, I bit the bullet. Were they worth it?
Pros: Balanced yet slightly warm and sweet, beautiful and realistic mids, price
Cons: Lack of sub-bass and a tad sparkle, microphonics
Summary: Arrived in a very elegant package, this "waterline" labeled RE-400 model looked very sharp. Just like with HM700/RE-400B, a lot of attention was paid to presentation of the product to the point where they actually had to include the storage hard zippered case with extra eartips in a separate bag so it doesn't interfere with a slim profile of the original RE-400 package. The headphones were sitting inside of a felt lined foam insert with cutouts for extra eartips.
Pros: very detailed warm neutral sound which is fun to listen to!
Cons: bass (I know its neutral and I shouldn't have high expectations for it :))

The RE-400 is quite easy to drive, but not the easiest. Better than the 64ohm RE-0, but like other 32ohm phones I owned, these need some extra volume to sound better and a bit more to shine. No amping is needed, though.
The new RE-400 is not just an improvement in design, fit and isolation but especially in sound.
Summary: Packaging and build:
The packaging is minimal and exquisitely so. The extra tips filters and manual are behind the felt coated foam holding the earphones. As I gingerly dislodged them from the grooves, I was struck by how tiny they are. I always try to avoid gripping the strain relief as a precaution, but it was difficult considering the size. The shiny bead blasted aluminium back goes well with the brushed aluminium housing. Which brings me to the build.
Pros: Magical mids. Warm lilt in the neutral sig. Fast, accurate and punchy mid-bass. Extremely comfortable. Easily driven,
Cons: Lack of sub-bass. Treble might be too smooth for some. Build quality could be better. Isolation is average
Summary: I got these as a backup to my RE-262. I wanted something I could run without an amp. The 400 provides that refined HiFiMan sound I have come to admire. The 400 absolutely squares up with my 262 when amped, but I really got them so I could run lighter (just a dap), they totally impress in this regard.
I think I may be the only one that really liked the twist-to-lock fit of the 262, they just work perfectly for me.
Summary: Along with the summary below, I have posted a Youtube video review of the RE-400. If you like the video, check out my channel for more reviews :)
The RE-400 has a sensible, well thought out design. Of special note is the half-rubber / fabric cord which cuts down on microphonics. The RE-400 is comfortable to wear with cable up and the metal earpieces seem quite durable.
Pros: Sensible and comfortable design, balanced sound quality, fantastic value
Cons: Overly large plug, sparse included accessory selection
Summary: I ordered these when my Astrotec AM-90s finally bit the bullet. Liking them so far, however the Left side is cutting out possibly due to a short on the plug.
Messaged HiFiMan and hope I get a replacement. I would had given a 5/5, but I'm knocking off 1 1/2 stars due to the durability problem.
I hope its just this one and it doesn't happen on the replacement.
Pros: Great Sound, Very good design, very comfortable
Cons: Slight durability issues, as Left side of the IEM is already cutting out
Summary: Basically, these IEMs blow away the cheaper stuff I've owned (CX300-II, MH1C). They really make a slew of genres and tracks sing with great presence and detail without a "harsh" sound or sibilance.
Coming from bass-heavy IEMs, they definitely lack sub-bass. But for most genres it's not an issue. And for the most part, the E11 amp (EQ bass boost option) can kick that up to where it's needed when it's needed.
Pros: Presence and detail are fantastic. The hint of warmth really makes for a smooth sound. No sibilance that I can find. I received a zip clamshell case!
