Sennheiser  RS-65 Wireless RF Circumaural Headphones with SRS Surround Sound Processor (Black)
Sound is good, but..
Sound quality is good. Can hear clearly in the next room. Rechargeable batteries are special type; may have to purchase only from the same manufacturer; could be costly. On/off button  and volume control are too small to use, particularly in darkness. Headphones sit with some diffuculty on the base for recharging of the batteres. Difficult to know the charging status. Poor operating instructions.
