PSB M4U 8 Headphones in original box, with a spare set of new ear pads, and user guide.
With Active Noice Cancellation - prefect for noisy environments, in my view better SQ ( Sound
Quality ) than BOSE headsets I have had in the past.
These are superb headphones, Bluetooth APTX HD ( HD is the higher 24 bit bitrate bluetooth connection,
the very best you can buy ) - easy battery replacement ( normal AAA "Triple A" batteries)
These were £299 new, so grab a bargain
