Works great

The only problem was that I expected the cables to use to plug into a TV would be included, but they were not. THis is the Cable that plugs into the TV L and R audio outputs. I had a problem finding them in order to make them work.

Great Service

Purchased Sennheiser RS165 headphones at a price lower than anybody.

They were shipped FREE and I received them in TWO days.

Would not hesitate to do business with Audio Geeks in the future.

Sennheiser RS 165 Closed Back RF Wireless Headphones

I bought these headphones for my 88 year old mom. She has hearing aids and these headphones fit nicely over her ear with the hearing aids in. She can use the volume button on the TV remote and doesn't need to use the buttons on the phones like she did on her last pair. She has arthritis in her fingers so this is so much easier for her. She LOVES these headphones and has told me no less than 10 times how clear they are, how easily she can now understand the spoken word on TV - she can enjoy her old movies and favorite tv shows again! They amplify the sound from the tv so she also has a lot of headroom. (The first few nights she used them, her right hearing aid wasn't working, so she turned up the TV volume to compensate. Now that both hearing aids work again, she turned the TV volume down by half.) This isn't a complaint at all, just a comment. Because these phones block out ambient noise so well, Mom can't hear her phone when it rings now! Highly recommended!

Long time interest in H F audio

Delivered on time--The unit is excellent and worth the money. The quality of sound is excellent and would recommend the unit to anyone.

The unit is connected to a Panasonic smart TV. I use a optical to analog converter to get the sound into the unit. I have about 50 audio channels on my satellite service and listen to them through this system. I can roam any place in the house and not use the audio. I have not tried it outside as yet, that comes when the temp reaches 80 or better.

I shopped and read way too many reviews but I am so glad I bought these for my husband who listens to the TV so the neighbors can also hear. They are clear with no background noise or static. Wonderful purchase and would definitely buy Sennheiser products again. Audio Geeks has a great site, prices, and delivery; received them in two days. Very satisfied with the product and the site.
