It is not the quality of the helmets to 300 euros, but at this price there is nothing else as good. The bass is powerful and well distinguished, the rest is quite correct, it is far from the level of simple atria. Numerous much more expensive headsets I've tried are worse. By cons ergonomic comfort issue and it's not always tip top, the wire is too long, the insulation is incomplete, but given the price it does not matter, a helmet with a good sound and comfortable as you would 5 times more expensive, take right away!
