So uh, I had a bit of an impulse buy moment and bought these on the pre-sale. Got them this morning, and begun putting them through their paces.
First impressions (no burn in yet)!
+ Soundstage is huge! Very airy.
+ Bass is tight and accurate, though also quite restrained. Powerful where it should be, but not a step further.
+ Vocals especially are quite well balanced in the mix. I'd say they are closer to transparent than most IEMs I've heard. Just a touch recessed, without losing any clarity.
+ Accuracy and detail in the upper mids and highs is excellent. Really good resolution. Hearing a touch of smearing in the lower mids. Will see how it develops.
- Very bright! Probably a little too much, as I can see them becoming fatiguing. Though I've been able to control it a little with the hard-centre silicon tips when compared to default soft silicon. Foam tips just make it worse so far as I've tried.
- Similar to above, they are not especially full or warm-sounding in the midrange. Which is not to say detached or unmusical, just closer to the analytical side.
They kind of remind me of Grado RS1 in terms of sound signature. But early days yet
Having not heard the H-200 I can't compare the difference unfortunately.
