I use these to listen to the television when I do not want to bother anyone else that may be reading or studying and I can hear it without any problems and it has good sound quality. It is also nice that it comes with a rechargeable battery so I am not spending a lot of money on batteries. The only bad thing is that if anything gets in between the unit and me the sound cuts out.
I purchased the Sony headphones to replace an old wireless JVC set, which always needed fresh batteries and the sound quality vared with tuning. The new Sony set has a rechargable battery and no tuning, and the sound is crystal clear. Also the new Sony set is lightweight and very comfortable. Extremely satisfied so far.
