I bought these headphones for my hobbies: music, television, video on computer, without disturbing those around me, and I subtract as much as possible to outside noises. Command time: a few days as agreed. Solid Packaging: transparent and rigid plastic Sennheiser and Amazon cardboard. Aesthetics of the helmet: it is a matter of taste, so everyone's opinion. Helmet: it is not used too much, it can be worn for several hours without inconvenience. The ears are well wrapped. Sound quality. I am pretty fussy about sound quality for music or all media platforms incorporating sound. I am very happy with this helmet. The sound is pure, without pronounced distortion. The different frequencies (treble of the log drives) are well distributed: all sounds are evident and do not jostle or mask. After several different plays (classical music, Lisa Gerrard, but also Bauhaus, Joy Division, etc.), this helmet keeps its promises is the greatest happiness! Slight downside, especially as we see in rock: the bass is slightly increased. But this deliberate modification alters very little LOEUVRE recorded by the artist. A small bass boost is not unpleasant to the ear. Moreover, as all helmets with head movements, rubbing on the son of the neck sweater or jacket agree somewhat; but nothing serious. With three meter cable, you can even use it to watch a screen placed three meters. In short, I highly recommend this helmet for those who want to have fun without breaking the bank!
