The BluWavs Headset from Mozaex is the first truly discrete 7.1-channel headphone, with 10 individual and individually driven drivers. They come with a console that provides full amplification for a package price of $1299. An optional multiband graphic equalizer (for the front channels only) adds $300. They were effective, though the frequency balance of the prototypes on display needs a little more TLC, as does the comfort for this large, heavy design.
