Query: Very bad product

After looking around a few weeks I decided to buy this wireless headphone.They spent two days at home and send them back to amazon. What a bad quality of sound !!! I could not even watch a film, listen to music or play any PS3 game because of the noise and interferences.Now I still want to buy a pair of headphones but I think I will stay away from wireless.PS. I am very satisfied with Amazon service, as they gave me a refund with no problems.
