So far, he did not make me very disappointed. I already knew in advance that some noise is present during playback. But if you find a "bad frequency" and relatively close submit it to the radio, almost no noise can be heard. Nevertheless, you should give up music with lots of bass.
The use of the car is AudiaX ideall with the included cigarette lighter plug and necessary because the battery life is only about 10 hours.
For everyone who wants to listen to his music without high quality requirements on its radio without having to buy expensive extra-boxes for iPod or other player that AudiaX FM Transmitter is suitable!
