I use this headset THOMSON HED655 for about a month. His biggest default is to be extremely durable material. It is not comfortable trs. The sound is OK for the price (40 euros). I am not an Ironbreaker, I have an AKG 242 for 30 years and it still works. It would have been enough of a month to put the thomson HS. A speaker has begun to dcoller and stroll in the atrium. Then it carrment any headset that has dcroche of the hoop. Discoveries that I held the headband headset with a small plastic tton absolutely undersized compared to the efforts it supports, especially since the tton is perpendicular to the efforts more common, as when we map the atria to set or remove the headphone. In my life I've used a lot of headphones, all prices, I have never seen such junk. The price quality ratio is close to zero-because of this extreme fragility. If I re c'tait n'achterais not this headset. T prvenus you!
