Lots of noise

May 31, 2013

This product is easy to use, install and comfortable. The only problem I have experienced is the Noise (Cracking sound) every few seconds or so. I bought a Similar Sony head phone but slightly newer model for the same price from C***** and it doesn't have that problem.

wonderfull must have

March 10, 2013

I originally ordered one wireless headset then after several months of great service I decided to order another for my wife. the headsets are a joy to use. No problem with battery charging as it wireless recharges in its stand. always ready. The sound is so clear that we use it for foreign (BBC) shows and movies with low sound. It is great for not bothering others when only one person is wanting to watch their show or sport. I use both at the same time with audio only feeding one transmitter.
