Wireless earphones: No Bluetooth here

Interesting review of a new way to listen to music with no wires and no Bluetooth technology. It says that music quality suffers when listening to music on bluetooth headsets as the technology does not have enough bandwidth and compression is needed. But with these headphones/earphones no compression is needed. The video shows Spencer Kelly strapping an N95 with a transmitter whose other end goes into the earphone jack.
The transmitter's range is 10 meters and it costs 300 GBP.

Now thats really expensive for a headphone. Instead, if I am really a music buff I'll buy a BOSE headphone and would not mind the wires.

Here's the link to the video.
