Summary: Build / Fit
They are much smaller than I expected. The aluminum casing is nothing too special, it looks very clean, and simple. The wires above the split are very thin with a feel like they could break easily if you use then regularly on the go.
Pros: Neutral, good to have, 45 degree plug
Cons: Neutral, could use a bit more bass, Microphonics
Summary: I have been using RE400 for over few months now. these are rather well known and well documented so I will only put stand out points that I think make it unique.
Light weight, made out of aluminium. Chord is fabric covered below y splitter. above that its plastic.
Pros: tactile balanced sound, good details for price, light and comfortable that looks good as well.
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.
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.
Pros: Great Sound, Very good design, very comfortable
Cons: Slight durability issues, as Left side of the IEM is already cutting out
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 every penny is best invested .
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: 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...
Pros: Balanced yet slightly warm and sweet, beautiful and realistic mids, price
Cons: Lack of sub-bass and a tad sparkle, microphonics
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.
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!
Summary: I bought these in early May based on nearly unanimous recommendation from people on a bunch of websites, and I must say they don't live up to their reputation. Some of the common things people pointed out were that they are excellent for the price, they have great mids, and they have bad build...
Pros: Excellent mids, decent price
Cons: bad sibilance, comically weak bass, unattractive, poor build quality, not very comfortable, 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...
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 :))
