These are SoundMAGIC's 2nd full size headphones, after the excellent HP100
I have just recieved these for review, but unfortunately they have a channel imbalance problem, will see if i sort it out or if i have to send them back.
They look great with their open air design and they are super comfortable like the HP100
Sensitivity：98±3DB at 1KHz/mw
Maximum input power：100mw
Connector：3.5mm,L style plug gold-plated
They will retail at $250
