Sennheiser  RS-65 Wireless RF Circumaural Headphones with SRS Surround Sound Processor (Black)
Good Compromise of Cost and Features
When I bought these (about a year ago) I very nearly purchased an Infrared headphone system instead, but I'm glad I didn't.  I mainly use these for watching TV later at night so as not to disturb others, and the line of sight limitation with Ir headphones would be a big detriment.<BR>Sound quality wise, there are two things to consider with wireless headphones; the headphone quality and the reception quality.  As I mainly use these for TV viewing, I haven't done a lot of critical audiophile listening, but the quality for TV is great, and music is plenty adequate for casual listening.  Reception wise, they are acceptable.  I live in a very dense apartment building in NYC, but by flipping around the three 'channels' provided by the unit, I can always get an acceptable level of clarity.  If you turn your head, there can often be little snippets of brief static, but by increasing the gain on the audio source, and lowering the volume on the headphones, a lot of this can be mitigated. I can't comment on range, as my 500sq ft apt. doesn't let me wander very far.<BR>All in all, the biggest complaint is battery life, a measly 4 hours, so you may want to purchase an extra battery to keep charged if your doing long term listening.  Comfort wise, I find the headphones pretty good, they don't tend to hurt my ears for the couple of hours at a time I'm using them, and although I've never had a problem with their construction, the headband connects to the headphones by a less than rugged plastic connector; so although they're mobile, you want to be careful of putting too much pressure on them.
