Hifiman IEM's: RE-400 and RE-600
Nov 3, 2014 at 12:36 AM Post #2,341 of 3,507
Just got the B3 Pro-1 a week ago. In my opinion, Havi B3 Pro-1 even when properly amped is definitely not an upgrade from RE-400 SQ-wise. Preference-wise, it's a different story. If you prefer a slightly (very slightly) v-shaped sound sig with slightly (again, very slightly) boosted sub-bass, more extended highs but still has a very good sense of transparency and micro detail retreival, B3 is in your favor. But if you want a real neutral, accurate, transparent sound especially in the mids department, RE-400 wins by a large margin IMHO.
 
B3 beats RE-400 in terms of soundstage though.

In terms of isolation, is the GR07 better than the RE-400? Considering the B3, the RE-400, and the GR07, but I need as much isolation as possible; I'm pretty sure the B3 has the best isolation, but I think it'll have too much soundstage for my main genres (rock/metal & rap). GR07 seems to have the best sound signature for my tastes, but I've heard that isolation isn't great (I'll be on a loud bus everyday, which is where I'd use these mainly). If the RE-400 has more isolation than the GR07, I'll grab it now that build quality issues have been said to be fixed.

I think I prefer very slightly v or u shaped sound again very slightly, and boosted and extended bass-treble (not fully analitic), also very good sense of transparency and micro detail retrieval, and great soundstage and imaging, and better cable. 
 
I prefer my RE400 for its ergonomics, isolation and for long listening sessions (untiring)

RE400 isolates 2-3db more than other two I believe, B3 isolation is good enough

for me, GR07 isolates more than the B3 as it has adjustable nozzle to adapt to your ear canal. B3 and RE-400 has about the same isolation.

At 1000Hz?
Isolation is difficult because of the greatly varying degrees of different frequencies.

Also, holy f*%# the B3 he got must've been a complete dud... Those distortion numbers, from either driver, whichever is less screwed up, are really high...

If you listen your music at 90-100 dB then it is better don't worry too much about the distortion, your equipment produce, but your pitiful ears for near future

Haha =)
They say you can listen to almost 90dB for several hours a day without hearing damage :blink:

But anyway, just cuz you listen to your music at 80dB doesn't mean the distortion figures will drop to zero. At 90dB, you're looking at 5% at the lower midrange... Which is apparently significant and pretty audible. Then again Tyll doesn't post separate order distortion plots, just THD+N so there's also that limit. It doesn't particularly matter as it looks like he got a potentially bad set, but having both drivers perform poorly is a bit of a concern.

i own all three, the havi, the re400 and the gr07 (but mines is the be) in this case it doesn't matter
 
for pure isolation
 
id say the havi and the re400 are almost on par with the havis edging out the re400s just a bit (both have 1 vent on them)
 
the gr07 is probably the worse of the bunch, its average i would say. passable for outdoor, and downtown use (with good situational awareness) but the re400s and havis will block out more.

how is it possible the BE version isolating more than the original gr07?! not complaining as i own the BE but that doesn't seem right......

  Re-400 to B3 Pro 1 upgrade feels like "that's what I'm looking for"
 
proedros, you are a hifiman fanboy (I (have been) also one loved Re-0 and Re-400) but you gotta try it...

 
i think their about on par with each other rather than a outright upgrade.
 
what i mean is that getting both will cause too much overlap imho!
 
both are transparent and have great extension from top to bottom.
 
and as stated previously the havis are slightly ever slightly so V shaped with a bit more oomph in the subbass and a bit more in the upper midrange right before siblance.
 
the re400s being a warmer more easy going ( i think a bit more likeable sound) 
 
the havis easily outpacing the re400s in terms of soundstage depth, separation, width and height
 
both are on the dry side with the havis being a bit "drier" and leaner than i would like. 
 
that said if you have the re400 and your looking for a similar sort of sound but a bigger soundstage go for the havis! its relatively inexpensive in a sense
 
and if your a havi owner and you want a more intimate performance with a bit more body in the vocals (especially female vocals) the re400s would be a great alternative
 
hope that helps!

Looks like I'll be buying these this Friday; was going to join the Havi family, but these seem to be the best for me. I might wait until I get my FiiO X1 to open them though; I'd hate to listen to these on my iPod Touch, I'd rather have my complete set up.

What's an RE-400 without the generally laid-back treble (but not a bright IEM), and with better build quality, within say, 200 USD?
 
I have a VSonic GR07 MkII, which I feel lacks realistic fullness and weight to the overall presentation (I find the low-end lacking in body) and I find the top-end peaky and often 'hot' because of the spikes/resonances. This is after coming from studio monitors and studio headphones that I work with.
