The best quality / price / performance possible, much better than some of its more popular cousins (the brand with the big B, among others) we immediately feel the quality of manufacture, the helmet is really strong and it shows. It isolates very well from the outside noise delivers excellent audio quality: is fun to rediscover his favorite music (FLAC if possible).
If you want a headset in a price that remains correct please, after more than a week of searching I have not found better in the 150-200 euros.
