Tested AD01 yesterday, wow it sounds really good!
It is not V shape to my ears, bass enhanced, but not V shape. The mids and treble are in pretty good balance, and bass is emphasized in a nice way, powerful and authoritative but doesn't ruin the midrange. I love the bass, the enhancement is just nice, bass is deep and punchy with good sub bass rumble. Clearly for bass lover, but bass is still in good proportion, not overblown. So still a pretty good all-rounder in my opinion. Bass power is actually tuneable to some degree by eartips. I will write more later after using it for a few weeks.
