I've been using it for 2 days now, works great. Quite a miniature thing made of good materials (to the touch). The sound is good, I didn’t notice a difference with the aux wire (I’m not special in sound). The only thing is that low frequencies (bass) are rather strong in some compositions, and the speakers start to rattle. But I don’t know if this is related to the speakers or this adapter. I made the basses smaller in the radio settings and everything is fine. . It's been in the car for a year now and it's great. The only point is that after some non-working time, you need to turn it off and on again in the cigarette lighter, otherwise the phone does not see it.
