I highly recommend the Sennheiser RS range. I've had a pair of RS180's for a few years now and they are excellent. Amazon have the RS160's for £99.99. They are closed backed opposed to the open 180's but I have read equally good reviews about them. They use Sennheiser's Kleer Technology which in my opinion is a lot better than Bluetooth. Also, no need for a dongle, just plug the transmitter into the headphone jack. The 160's have a portable transmitter which is battery as well as main powered.
There is a newer range but I would save a bit of money and go for the previous version.
