Recommendations: wireless headphones?

God, I’m writing some exciting headlines today… anyway, I’m just looking for a bit of advice. Winter is the season for console gaming, but unfortunately I usually want to fire up the Xbox late at night when my better half is in bed. For some strange reason, Liz doesn’t appreciate the sound of gunfire, grenades and spaceships when she’s trying to get some sleep. So can anyone recommend a decent (and not desperately expensive) pair of wireless headphones? Ideally something reasonably lightweight, with a transmitter that isn’t the size of a brick and without stupid ear bits that won’t fit on your head if you wear specs.

Any suggestions appreciated.
