Sennheiser RS 140 Wireless Balanced Headphones

I've owned 4 sets of these Sennheiser wireless phones. Not only over priced, they are not compatible with most audio equipment in the sense that they have their own volume control which only works when the input volume is cranked to a disturbing level. These are represented as personal listening devices but when everyone within a 900 foot radius of the input device must tolerate the sound, I'd call these a complete FLOP. IF you seek wireless personal listening device, please locate a seller of TV Ears. They cost less and work flawlessly. Some ENT physicians actually sell them.
