"The search for the perfect set of wireless headphones is often one fraught in disappointment and annoyance. First you have to decide between two technologies: Radio Frequency (RF) and Infrared (IR). At the very first step of the decision to go wireless, you are making a compromise since neither is perfect. RF is often plagued by interference and IR requires line of sight between the headphones and the base station. IR headphones tend to be interference free, since good placement of the base station can ensure a good connection. Either the connection is there and you have sound, or the line of sight is interrupted, and you have no sound. Quality is very binary: either the sound is present and at maximum quality, or it isn’t there at all. RF headphones operate on a gradient of connection quality. Depending on radio interference, your connection is almost never at maximum possible quality, but you have a more reliable connection." Designtechnica has a detailed review of a wireless headphone that might be a good read if you don't know much about how wireless headphones work and what the pitfalls of them are. Beyond that it appears that the Sennheiser RS-130 headphones at about $150, are a good choice for those wanting to enter the world of wireless headphones.
