Sennheiser  RS-65 Wireless RF Circumaural Headphones with SRS Surround Sound Processor (Black)
very poor plastic construction, but can be fixed; bulky
Plastic pivot axes were broken after about 1 year of occasional usage. But sound is still there, range is satisfactory (not 300 feet as advertised, but sufficient for a regular house, 50 feet). Rechargable battery still works after 4-5 years no replacement, but capacity has dropped and need recharging every 2h. <br /> <br />Because it still works I gave 2 stars. Otherwise construction is very poor. It will certainly break on you even if you do not abuse them at all. First ear peace was broken after 6 month. I fixed it with duct tape, but it did not last. So I put a metal bracket (from used computer slots) and taped both peaces. Looks ugly and bulky, but it works for last 3 years. After about one year second ear peace was broken I fixed it (you guess) same way. <br /> <br />I doubt this product has ever passed ANY quality control. Buy only if you have spare metal brackets and know how to tape it.
