Sennheiser  RS-65 Wireless RF Circumaural Headphones with SRS Surround Sound Processor (Black)
Not perfect but I love the mobility!
I really enjoy the mobility and the light weight. The sound isn't bad either. Typical of the better Sennheisers with decent bass and a nicely balanced high end. The downside of the cordless design though is that they lack the extreme detail of the best headphones and the highs aren't extended enough to get a silky topend.<BR>I hesitated to buy these though based upon some comments by reviewers. There is some truth to these comments but they don't bother me. Yes, the headphone cup is a bit small and they do seem a bit tight at first. But I'm an over six foot male with a large head and average size ears. My ears fit fine and after just a couple of minutes they don't feel tight at all. I can wear them for hours comfortably. And reception isn't perfect. I can use them most anywhere in my large house but there are some deadspots based more on how I turn my head than distance. The good news though is that just a tiny head adjustment clears it up.<BR>And lastly I recommend the SR65 as the sweet spot in the line. It has the autotuning feature which I suspect is important to decent reception and it has the surround sound feature which basically seems to feed the deeper bass to both channels. It does give more ambience and better bass. It definitely does enhance the sound of some recordings. The SR85 lacks the surround and substitutes dynamic noise reduction. That's evidently a compander system that according to the SR85 reviews seems to compress the dynamics. No problem here on dynamics.
