Terrible range and sound quality even in car (bought it to go wireless in a small room - no chance)
As electronics engineer decided to try U tube modification to increase range - some improvement but sound still not good...lots of hiss. Very poor product.
Sound quality poor at best. Too much interference for my liking.
Listening to audio books is impossible. To be honest I feel it is a waste of money.
I gave it 3 stars only because it works, but not well. Feels cheap and nasty.
