The Sennheiser RS 175 RF is an excellent product, but when compared to the more expensive Sony's the differences are evident

I have upscale SONY headphones and an old AR pair neither of which has this issue and cost half off what I paid for this unit.

Sony said not compatible.

I purchased was to replace a Sony RF head phone...which worked right from the first time I plugged it in

Yes it's much more expensive than the Sony but considering the Sony had so much noise and frequent signal disconnect, it's worth every extra dollar I spent on this Sennheiser.

We bought much less expensive Sony headphones and don't have problems using 2 sets of headphones to listen to the same audio source.

The Sony's had terrible static (no matter the settings), terrible sound and terrible range

the headphones on the cheaper Sennheiser and Sony would eventually just cut out.

The first three defective ones don't even rate one star!I liked the Sony design a lot better than the Sennheiser's, but sadly Sony discontinued that part number

We got these to replace a pair of Sony wireless which fell apart after 1.5
