For anyone interested, just a short write up
Okay, upon spending some time with the RE-400, I am ready to post some more impressions [they will be of course added to the review but probably not today]
Comfort - nice fit, deep insertion, if you focus on the music, you can almost forget you have them
Overall 8/10
Build quality - quite nice, aluminium shells, with shiny plates on the back. Very small but feel sturdy
Overall 8.5/10
Cable - perhaps the only disappointment, the cable itself is fine, it is sleeved in a rubber sleeve.
Overall 6/10 [8 quality, 4 convenience]
BUT it gets tuck on everything it touches and then it moves with it or slides down. I will really need to get it tucked with the included clip.
SOUND - I HIGHLY recommend using some sort of bass boost [in my case a preset in my phone] as without it the HP feels a little mediocre to my ears, very mid centric. The bass boost bumps up the treble and bass noticeably and balances everything out quite nicely, save for vocals perhaps.
Without the boost, the HP are just too mellow for me.
Works great right off your phone :]
Bass - well initially it was mostly texture and no punch. BUT the bass boost EQ preset in my phone essentially fixes it. you lose a bit of resolution but gain a tremendous amount of nice tight bass [actually the only HP that does that. It goes from little bass to plenty] So with this preset the bass is really nice. Detail texture, punch. Obviously not as deep and detailed as the HE-6 bass, but can quite compete for an IEM It punches a bit more [with bass boost on though]
Overall - 9.0/10
Mids - Very nice. Also can quite compete with the HE-6. Of course not as detailed and full but still really nice overall.
Overall 9.0/10
Vocals - Okay this is perhaps where the difference is most apparent. HE-6 has just awesome vocals, perfect. Now, RE-400 still has nice vocals, BUT there is a slight dip somewhere in the high mids/lower treble where vocals appear and as such it affects vocals only and it makes certain sound too mellow while others are a bit too pronounced. It varies from artist to artist. For example Michael Jackson is a bit too mellow while Mike Shinoda is a little harsh. But nonetheless even through these nitpicks, they are still quite nicely detailed. The bass boost might be partially responsible for this
Overall 7.5/10
Highs - here the bass boost helped a lot. Kinda a cure it all. It gave instruments the attack they needed as they were a bit mellow before.
Overall 8.5/10
Instrument separation - is perfect. Seriously really, really nice. I dare say almost as good as the HE-6, and we are talking the fraction of it's price.
This is the one area Hifiman has perfected. No matter which HP, the separation is just phenomenal.
Overall 10/10
Soundstage - I haven't got much experience with IEM soundstage but I'd say it's marginally different than with HE-6
With them you get more of a speaker soundstage with these IEM, you get left-center-right. But I didn't find anything bad with it. Much like HE-6, it's not large, but quite nice, more so for an IEM
Overall 8/10
Value - Okay. For a 100 USD [130 in my case] it performs excellently. I now can perhaps understand why people were called it a new benchmark between entry/mid level IEM. The sound signature and overall presentation is close to its bigger brothers but for the fraction of their price and you can put them in your pocket.
You get a worthy HP that performs exceptionally for it's price.
Overall 10/10
Overall 9/10
I think even if they have their kinks, the asking price simply makes this a bargain. No doubt about it. You get a performer that can almost compete with balanced armatures [okay almost] for less than 1/3 of their price.
Recommended just for curiosity sake
