I have to say, I'm really impressed by the sound of the H-200, impressions were something I did promise everyone, so initial ones are below. Final impressions will come up in my full review.
I'm going to start out with the midrange, I feel that is the part of the H-200 that is more or less the most accurate. Really, T-Peos did a good job of finding an IEM that would produce the midrange in such a beautiful fashion. The lower instrumentals have a hint of aggression to them making guitars sound a little alive and detailed while the clarity up top is strong, but never harsh. Vocals were something that I originally did find sibilant, they have toned down quite a bit; some are still though. A beautiful balance down low and up top allow for proper vocal reproduction. The mids are extremely linear in comparison to the rest of the spectrum.
The low end of the spectrum has a strong focus on the sub-bass. The bass as a whole has a huge focus graphically. Quicker decay allows the bass to retain strong accuracy. Texturing is strong, with good presence. It's a little more solid than it is fluid while the lower bass is strong offering good impacts that actually remain quite controlled and tighter than you'd expect. That said, the mid-bass punch of the 'phones actually sounds in-line with the rest of the bass. That said, the graph makes the bass on the H-200 look well out of place and overly strong, it's quite controlled.
The treble does still have its spike at that 10 kHz. This can create an upper treble that is a little too metallic and a little sibilant unfortunately, the main complaint I have with the T-Peos. However, the rest is actually quite strong. The treble does have good detailing overall with ample extension. Separation seems a little hindered as it can feel like the upper treble smears a bit more than I'd like. The lower treble has a very nice presence to it with great extension and overall detailing.
There's quite a bit that the H-200 does splendidly, the midrange, bass, even much of the treble. There is some stuff that it makes mistakes on, that 10 kHz spike is the main issue; the dip at the 6k makes it a little worse as well. By definition, the H-200 is v-shaped, quite honestly, it doesn't feel that way to me... It just doesn't.
