Im in the market for a decent paid of wireless headphones, mainly for use on my pc. I currently have the Sennheiser RS130 but they drive me mad as they always auto switch off after beeping a number of times when there is no sound being received. Im sure this feature is fine when watching a movie but on a pc its annoying because I can go for a couple of minutes online without hearing sound but this doesn't mean I want a series of annoying beeps before having my headphones switch off.

Any ideas? Or any that don't beep all the time?

Thanks
