Before buying this headset, I had read some reviews posted customers attesting to the unreliability of this helmet. I told myself that paying attention, that he would hold long enough. Following receipt of the latter, I was really pleased with the quality of listening. It is below a beatsbydre in terms of insulation (since it has no system noise), but this does not really bother as the sound quality broadcast and insulation are correct. The headset is lightweight and suitable / adaptable to the head. However, cracks appear after a few months of use, and finally a hoops may break. It is a product to avoid anyway.
