Pros: Sound - lows, mids and highs are realy great. Epic soundstage, mids and lows
Cons: Size, im afraid to use on public, because i will look like Frankenstein.
Bought these locally brand new for $195. For that money they are amazing. I have owned XBA-4, but H3 are much better. Sound quality wise they are comparable to Audio Technica CK100Pro and other top tier iems. Tf10, xba-4, westone 2 is easily inferior to these.
But you need burn in H3 and your brain to apreciate H3 sound.
There are 2 groups of people - who dislike them and who love them. In first week i disliked them - they lacked highs, bass was bloated and they were very warm. Thats because i used CK100pro, which is very dry and bright. But after week suddenly i started to love H3.
