Shipping much faster than expected! The product is fully compliant and works perfectly; no hiss or interference generated by the engine! Volume good, not BESOI to the bottom drive. Works well on Android and Iphone 3G safe (there no headphone icon that appears near the battery but the sound goes very well !!). Finally I recommend to buy with, it will save you from going to the super corner market to buy an extension cable male / female because in height with silicone or other shell; transmitter is not plugged well. With the plug of the cable no problem which allow more to bring the transmitter near the cigarette lighter to recharge, by cons quite often; but the charger and cable provides are really well made again !! In conclusion, I recommend !!
