Have this equipment some reviews read and trusts that this device is working properly with me. However, I realized that it did not meet my expectations. The reason is that permanent buzzing in the final beneficiaries is available, which is not wegbekommt. The background hum is perceived as very annoying both when playing music on a home radio as well when playing music from I-Phone on the car radio and heard is, at least from me. I can not recommend this device, unfortunately.
