I needed to acquire a new USB headset as part of a new job based at home. Convenient. No break in. The neck is very wide and baby will grow out of this before the neck fits! Einfach den großen Knopf auf dem Kopfhörer drücken, dann die Bluetoothverbindung suchen und zack, fertig. The headset has 2 volumes, off or on, on is fine, its perfectly comfortable, it sounds good, it wont be damaging your hearing, but it just is not adjustable. The fact they are wireless is really convenient, no more tripping over wires! The piece just about where the cups attach to the headband is notorious for cracking. Buddha ears, the earmuffs are quite narrow, it feels good for 25-30 minutes, but more than that; it starts feeling uncomfortable. We attached this to our fifth wheel bumper, and it is very sturdy.
