As the post says, really. My only chance to play games is later in the evening, but our boy's bedroom is right above the lounge, so I need some wireless headphones. Ideally, they might charge when sat on a cradle, rather than eating batteries, but outside of that, not much else required other than being wireless. I'll never be using them for film or TV, so they don't need to rock my world with their sound reproduction, just good enough and able to handle being turned up reasonably loud without distortion. Maybe that's standard these days - it's been years since I bought any headphones! Last pair was some £30 Sennheisers which I thought were just fine for listening to CDs late at night - although they're old, tired and wired!
Budget about £75.
