This Motorola Bluetooth receiver is a gem. The packaging is beautiful and brings into focus before the product while protecting it effectively. The package contains: the receiver, a jack / RCA cable, USB charger US format and adapter US plug / French plug and a small documentation. The connection is very simple: the jack into the receiver, the RCA in its audio system, USB for power ... and voila. It is therefore essential to have an audio system with an RCA input. If necessary it will buy a jack / jack cable. No optical output either. Just press the button positioned on the receiver facets and it starts with a little deep and enjoyable. Pairing is very simple, on iOS is looking for a new Bluetooth device and voila! On Android, if only to have an NFC device, a "pat" and it's done. One advantage of this receptor is the visual part. With other receivers you never know if it is connected ... no worries there. The faces light up depending on what happens: pairing, music distribution, new connected device, ... Everything is visual and rather pretty. My only criticism that makes me remove a star, besides the adapter US / Europe we will never see once laid, it is the lightness of the object. At the start I found it rather "heavy" but in the end it is not enough to hold the weight of the cables connected to it (audio cable and USB charger). Thus, resting on the edge of a piece of furniture, with long wires, the finished product by tirelessly "raising the head", we must move forward a little so that the cables do not draw too much on the receiver with the risk dropping it. A heavier coat would have been perfect.
