I needed headphones to use with my new killer 4k home theater system since I live in a condo with paper-thin walls and and only have time to watch TV late at night. I also run Spotify on my HTS more than I watch Tv. I purchased the rs175 and rs185 and compared over a week.

Replacing a pair of Sennheiser 450x with these. Reception around the house is MUCH better and am not getting the battery warning I kept getting with the 450x. Also like the recharge stand vs the 450x recharge.

The Sennheiser RS185 are wireless headphones, but quite unlike the sea of wireless sets you'll see elsewhere. They don't use Bluetooth, but a bespoke RF system that offers much better range and an uncompressed audio stream. That's right, these are ‘hifi' wireless headphones.

Very comfortable; Good sound quality; Reliable wireless with good range

I've auditioned a number of wireless Sennheiser models over the years and was always satisfied with the sound. Sennheiser claims their latest 'phones are better than ever, and the RS 185 is the best sounding of the twelve wireless models the company currently offers.

New lossless wireless audio technology; Two-year warranty; Lightweight design

Wireless 'phones can't play loud
