Hifiman RE-ZERO | Hifiman RE-400 |
---|
Bit nasal tonality (5k bump), too forward mids | Neutral tonality, mids neither forward nor recessed |
Shimmer cut (8.5k null) | Neutral shimmer |
Much more pronounced highest end shelf
(6 dB) | Very slight if any high end shelf |
Slow highest end rolloff
(17kHz; better than B2, similar to GR07) | No highest end roll off
(can hear up to 19.5k)
|
Somewhat gritty feel to the sound
(mids distortion?) | Smooth sound with only a hint of extra crunch or midbass boost |
Very long mids reverberation | Less reverberation in mids, more in highs |
Very solid bass impact | Slightly softer bass impact, but felt more |
Definitely rolled-off subbass, a bit wide-band boosted bass (2 dB) | No apparent subbass rolloff, perhaps even a neglible low bass boost |
Best performance only with aftermarket tips
(hard to get Fostex elliptic single flange for me) | Best performance with stock large biflange (crunch & reverb) or Comply Ts400 (midbass, non-reverbed, analytic) |
Medium depth insertion (reference plane?), "just" achievable with single flanges | Shallow insertion (-3 mm?); deeper cuts highs, upper mids and boosts midbass a tiny bit |
Somewhat uneven decay | Very even, smooth decay |
Trapezoid soundstage (sides noticeably closer to head) with slight hole in the middle | Linear soundstage, superbly coherent |
Decent soundstage height rendition | Very good soundstage height rendition |
Uneven soundstage depth rendition - "in the face" vocals, bass sometimes in-head | Very good soundstageome depth rendition |
Definitely hardened cable | Probably the same cable at the top |
Flat wide minijack (not exactly Macbook friendly) | Tapered minijack |
Balanced cable with adaptor | Normal unbalanced wiring |
Does not work that well with Comply T400/Ts400 in any form
Reduced "nasal" feeling, grittiness, and reverberation, but also much reduced bass impact and subbass amount | Works extremely well w/ Comply Ts400 normally mounted - faster bass impact, notably less reverb (almost like B2 anechoic room), no extra crunch, wider soundstage, warmer?, superbly extended subbass
Generally way more analytic (not brighter!), but warmer
|
Not too sensitive wrt insertion depth, but picky about tips | Not picky about tips, but instead about insertion depth |
Medium-high sensitivity for an IEM
(100 dB/mW, 16 Ohm) | Generally half (-3 dB) as loud (102 dB/mW, 32 Ohm) |
