These are really good to have sound wise,but far as quality you might only want to get these as a back up pair.My very first pair that came with my sony walkman mp3 player lasted about 4-5 years,I can deal with that.I bought my first pair of these to replace them and i pulled them from my bag wrong and one of the earbuds came of killing the sound from it,o.k. partially my fault.I got another pair and while i was at work i was jamming and then i litteraly tapped the wire and the left ear went dead WTF.Long story short good sound bad quality,buy for back up only!
