Recently purchased the B200 direct from Brainwavz. They look identical to these. Soundwise I was very disappointed; would ave returned but you have to send to Hong Kong so the effort to go through all that wasn't worth it. They're now my backup travel set. At $80 if the 150's sound similar o the B200 I'd say it's a 50/50 .
I also recently acquired the 1More Triple and IMHO they blow the B200 away. So unless the B150 are markedly superior to the 200 I'd counsel against.
