Philips SHD9100 Wireless Headphone

Its new $345 SHD9100 headphones transmit sound wirelessly via the 2400-2403.5 MHz frequency, which Philips says results in less interference, lower power consumption and better sound quality than analog FM transmission systems.
The headphones employ a pair of 50mm drivers and will operate in a 30 meters range. They come with a docking station that doubles as a recharger, giving up to six hours of continuous playback time.
An ultra-lightweight headband and breathable fabric ear cushions are intended to make them more comfortable during long listening sessions, and automatic tuning means set-up should be straightforward.
