I have had another set of Sony headphones for about four years but the wire became exposed so I decided to get a new pair. After two weeks of listening to music one of the ear buds started to static. Now listening to music isn't enjoyable due to the constant static over the music.The pair I had four years ago still work perfectly fine so I guess it's just this particular set.
