already owner of a SHB9000, it was nice, but uncomfortable, sore pillow after 45 min. there, I now have the SHB9100, it's great. basically it is like 9000, a great sound, light but with good bass present, good battery life, a good look, a proper finished (often advertised as his weak point but I think it is very correct. sufficient to 'take care of.). comfort is finally at my expectations! ie equivalent to AKG K830BT (I also but a slight BT compatibility with my galaxy S2 I do not know why). I highly recommend this brief 9100. He got a perfect for me.
