Well the sony is nice but older firmwares of k790 do not display the name of track playing. . So do upgrade your firmware. . . Also there is a nice stereo bluetooth comparo on Mobile Phone News and Reviews (MobileBurn). . . Go and search there. . Sorry i do not have the link . . .
thx guys...guess sony bluetooth looks more obvious then.
As per the review the sound quality is even better than hmp-70 .
Just the ear plugs that i dont like. It becomes more like a one person use ear plug. Also hope i dont have the problem with bluetooth headsets like the RF ones which used to suddenly lose connectivity with the transmitter in certain angles.
