i find H200 having pretty enough bass, actually sometimes even too much, however where H200 struggles is bass tightness and clarity, do not get me wrong, bass articulation is pretty good but if we talk drums, percussions, bass guitar and similar i must cincur layering is not perfect. mind this the only relatively cheapo i heard able of stellar bass is Sony MDR7550, yes i did not like Sony sig but bass on them is one of the best i heard irrespective of price.
so when i talk bass on H200 i rather wish it would have detailed punch, crispness and immediacy, but the only IEM i know is able is 1p2 and another one bass only is 7550. so i wonder what lack of bass we talk?
as regards mids and vocals i find H200 being even a bit mid centric but still offering more linearity than some mid centric in your face IEM.
trebles are not strong point of H200 and upper mids have some harshness which makes them bit aggressive and adds a bit sibiliance... but come on, tell me from top tier IEMs which are not possessing some sibiliance? even 1p2 or ASG or even famous UERM have a bit of this to less or more degree...
yes, i like "analogish" warmth in mids and bass but i never liked warmth which eats down detail and this is well known compromise you habe to balance out in many tube gear and perhaps in choosing IEMs too. so yes i like warm but tight and crisp bass. Consider me insane contrarian here
