Bests & Worsts Reviews from Amazon

Two major problems with this headphone. 1. Very small transmittance range. If I walk to a different room just 30 feet away from the TV, the sound in the headphone starts breaking. 2. There is no access to the battery compartment. I contacted Sony customer service about this, and they confirmed that the batteries are not user replaceable. If I need to replace them, I have to send the headphone to the service technician. So their specs published on Sony official website is deceptive. It states that this headphone can use both Ni-MH and simple AAA batteries. I would not recommend this product to anybody unless you are going to use it next to the TV and dispose it in two years when your original batteries go bad. Update. After using it for almost two years I would like to change my rating from 2 star to 4 (maybe 3.5)stars. The problem with battery replacement still exists but my battery is still good and shows no signs of going bad so far. Hopefully it will last a few more years. The limited transmittance range is probably a problem of my house (other people have no complains). The quality of materials is good and the headphone is still looks like new.
