Not exactly a budget pair but... I'm not going to start another whole new thread on non-budget IEMs am I? Not like I'll get enough of them to justify its own thread
(B1) Hifiman RE0
reviewed 2012-11-30. Thanks to
kalbee for exchanging these and a pair of Hisoundaudio Popo for a pair of MH1C!
Currently available at: ~$49
Driver:
Dynamic
Impedance: (higher is better) 64ohm
Minimum volume setting required from Fiio E17 (lower is better): without EQ: 24/60 with EQ: 26/60
Cable: Y-split slick plastic cable with 45 degree plug, length down to trouser pocket
Nozzle Size (widest part of tip): 5.5mm | Preferred tips: stock biflanges
Wear Style:
Straight down or over ear
Accessories
(3.5/5) – Single-flange silicone tips (3 sizes), biflange silicone tips (2 sizes), replacement nozzle filters, shirt clip
Build Quality
(5/5) – All metal housings and long strain reliefs, solid (but not too solid) plastic cable
Isolation
(3/5) – two vents on the back of the housing apparently connect to the ear side of the housing as vacuum seal does not occur with any tip combination.
Comfort
(4/5) – Light and small housing, medium sized nozzles and a generous selection of tips should mean that you will find a comfortable fit.
Sound without EQ: (9.0/10) (expect to see some low scores even from many $200+ heavyweights here; I am not tolerant of sound not matching my sound sig preference here. That's for sound *with* EQ)
These phones have a very neutral sound signature, matching my tastes very well. The lower mids and bass will tend to the lean side for most people, making for a cool note presentation. The treble is not the smoothest (that crown currently goes to the MH1C) but it is very well proportioned. The sound with and without my custom EQ for these share more similarities than differences, something that can not even be said for the MH1C (because of its bass boost). The main difference lies in a higher tendency toward sibilance, mainly explained by a peak above 10kHz using the stock small biflanges. However it is better in this regard than the Etymotic series with similar sound sig, mainly because the latter's main resonance peak is lower in frequency and higher in magnitude (unless you manage the past-the-second-bend deep seal that the etys were designed for. kiteki calls it "Earrapic" I believe
)
FR curve (on my ears, using small biflanges)
Gentle subbass rolloff
Various small peaks and dips in the treble
Main peak over 10kHz (higher is better)
Sound with EQ: (19/20)
The RE0 finds the usual gains in refinement with EQ applied but the difference is less than with most other phones. The main difference lies in a reduction of sibilance and an improvement of timbre, and a darker sound in the sense of better blackness between instruments for better detailing:
Quote:
They sound quite nice without EQ. I'd even be tempted to say they sound airier without EQ than with EQ but the airiness makes and breaks the sound at the same time. It is airy even when no air is necessary--like listening through Darth Vader's breath mask. No offence to the RE0 though--every phone I've heard sounds like that to some extent without EQ, with the exception of the MH1C.
On the other hand, because of the ported design, there is more air to the sound and a more reliable seal (doesn't become muffled in the first few minutes as sometimes can be the case with completely sealed models) over the likes of the MH1C and the Etymotic MC5.
Standard disclaimer: sound with EQ of course changes with the EQ used. Despite the use of tone sweeps and the equal loudness filter standardizing much of the EQ process (and the resulting FR charts), it is still possible to get better sound with further fine tuning of the EQ to real music. The score with EQ is affected by how well I've profiled the EQ for a particular pair of phones. Still I find it worthwhile to dedicate a section of each review to EQ because phones always sound so much better with EQ (
reason).
Value (no EQ available): 9/10
Value (with parametric EQ): 5/10
Pros: fantastically neutral sound signature; highly detailed; quite smooth
Cons: not exactly budget
