Sennheiser has got their own pair of wireless headphones coming out called the MX W1, which use Kleer's wireless audio transmission technology to produce cd quality sound wirelessly to your headphones. The heaphones receive audio from a wireless tranmitter that can be plugged into any mp3 player and if your device happens to integrate Kleer tech, you won't need the dongle at all.

MSRP - $600.00 USD
