Query: Junk - lasted 6 months

Don't purchase these headphones. I have purchased Sony headphones several times and all have failed. This model was purchased 6 months ago and the right side just stopped working. In fact, I just looked at the Best Buy site and their reviews said the same thing that we experienced. I saved the Sony packaging and the Amazon receipt almost expecting these headphones to fail and they did. I just got off the phone with Sony and they offered to "exchange" the headphones for $19.20 - I paid $19.99 for them and this was no bargain so I passed. The warranty was for only 90 days and we had them 6 months - I think that expecting them to last a little longer is not unrealistic. Take my advice, don't invest in Sony headphones - look for a longer warranty and something that is made a little better.
