Bluetooth audio headphones

Even if Bluetooth is not the hottest technology in Japan, there are
manufacturers that believe in it. Princeton is one of them and they
prove their love for Bluetooth by unveiling the BTST-9000D, a
Bluetooth audio headset with audio adapter. It is Bluetooth 1.2
compatible and has a battery life of 6h in use and 320h in standby.
the design is quite mediocre though, so it's not with products
looking like this that the Japanese will be converted to the Bluetooth
technology...
