Quote: I'm going to say they are among the best, yes. Especially given their price point. However, having heard some great dynamics myself (EX1000, ASG-1, HJE900), they all have their pros and cons. But all have one thing in common, musicality and a naturalness that BA just has issues reproducing at the same price point. They can compete with headphones several hundred dollars more expensive. There are some trade-offs though. Like most 300+ IEMs now have some sort of removable cable which is a huge plus. But to say that the RE-400 can match some $200-300 is a very fair statement. To say they can compete with TOTL IEMs (FitEar 334 or 1P2) is another story entirely (and in my opinion ridiculous). I really look forward to hearing the RE-600 and seeing their price point. If they continue like with the RE-400, they might be close to or might even be giant killers. Quote: Yes, I agree with this. I wouldn't say they are reaching basshead status (unless I need better sealing tips, since I'm using what they were shipped with, I'll test that later) they definitely have bass that is less than neutral. Their treble extension is as good as to my ears as my ASG-1s, and have more prominence (kind of annoying really considering the price difference). I can imagine, though haven't tested, the music that sounds a bit dark on my ASG-1s being perfect, or close to being perfect on the RE-400s. However, in comparison to my ASG-1s, the soundstage is markedly better and imaging is better as well. Instrument separation is surprisingly about the same. Vocal separation the ASG-1s inch out a bit. This is mainly due to imaging though. The imaging is a bit... odd on the RE-400s. Some things don't just sound right, like the positioning seems off, while the ASG-1s seem to hit it spot on. The vocals aren't forward as they are on the ASG-1s so that might play a role in being able to pick out position and individual voices on the ASG-1s. I'm really curious to hear the Tzar 350s now. Having had the chance to demo two TOTL Univeral IEMs (the TG!334s and the Tralucent 1P2s), and having extensively auditioned the ER4s, to be told there is something that is as good as the ER4s if not better in clarity and accuracy is intriguing to say the least. If the RE-600s can come close to those and be in the $200 price range, I'd imagine that HiFiMan will have many fans. Note: I don't own these *yet* but I imagine that I will very soon. For the price point, these will be the perfect back-up IEMs (lets face it, they'll probably be my alternate to my main IEMs the ASG-1s (soon to be G-2s)) for me. I always like to have two, and the reason became painfully apparent to me when my HJE-900s died. Having to use the Samsung earbuds that came with my phone for the one day that I needed to use IEMs was just painful.
