HIS QUALITIES: Already when we put it on the ears: comfort is incomparable! A sound of excellent clarity (it is like in nightclub with nuisances less) A true DJ headphones ......... It is isolated from outside noise (car, TV): one feels alone! The bass is folly - the term "excellent" is not strong enough to express the quality of this helmet OPTIMUM the adjustment of the helmet in him is classic mm the price / quality ratio is perfect! this is the first time a Philips multimedia conquered me so much. FAULTS: none yet - only use on the duration may be able to contradict me I highly recommend the purchase of such a helmet
