I used this to connect my iphone and my car's aux input. Sound quality is ok, could be better. The base is weak. Communication is reliable, I used it as a receiver mode; I haven't tried the transfer mode yet. The audio cable is a weak point here: it is flimsy and after 1 month of use the cable shield at the junction with the plug is demanding to come loose due to fatigue, I believe, although the installation hardly moves. I need a new quality cable soon. It could also improve the sound quality. Update: after 6 months of occasional use. Bluetooth is not recognized. You get what you pay for. From now on in the trash can
