I have allowed myself to be convinced by the other 5 star reviews and this Wireless Audio Set ordered. For safety, I have but also the two appointed each more than twice as expensive two sets Marmitek Audio Anywhere 625 and Audio Mate AM8112 Digital Audio Adaptor. Fortunately, because this set, however, is very weak. The sound is distorted, the range shortly. Even the Marmitek Audio Anywhere 625 was not much better (especially fiependes background noise when the USB charging cable was connected to the PC / notebook and not on an extra USB power adapter for sockets). Recommended is ultimately so the audio Mate AM8112 Digital Audio Adaptor, mainly because transmitter and Reveiver are both really practical and above all much more flexible for mobile use, as it can also be used due to built-in battery with no USB power connector and you look so with the small Reveiver can move freely in combination with in-ear headphones (or headset) and can go (with me) even into the next but one room or change the floor, while the sound quality does not decrease (selbstversändlich it cracks when walking, if you are then remains the connection is stable again).
