I'm on my second copy, and still good in sound. I confirm with regard to the quality of materials ... very fragile, you have to be gentle with this headset. It remains none the less very comfortable, easy to adjust (it pulls the hair), very light. This helmet remains and this for almost 30 years a reference. You must add in addition a strong transportation house and it's good. Its weaknesses are the son who cut the sotie HP and exit of Jack, which involves playing the soldering iron to repair, and fixing HP that break, then you have to play the glue gun. This headset is very complete ..... we listen to music and a craft workshop.
