The use of this headset is not recommended and can lead to unsightly hearing. Apparently there is a volume-level control that surrounded at a certain level at a frequency noise the headphones. This is as follows: We hear, for example, an online radio station. If you're doing the volume set too low, it can happen as I said, that the headphones thinks there are no more data sent to him, even though the radio station is still running. The headphones switch then without warning with an extremely loud crack on as extremely loud continuous noise to which not only leads to scaring sure of oneself.
