Following my disappointment, the seller contacted me to offer me a new shipment. Material well received on time, conforms to descrptif. I tested it and there it works very well. I connected a headset and a bluetooh pregnant, 2 work very well. Not together, separately, but very good. The pairing is good (always a scare when all LEDs flash ...), the range is average (about 5-6 meters with wall-obstacle), the sound is good. Surprisingly, there is a small shift in the sound between my speakers and headphones (period which does not occur with headphones san wireless / radio frequency). Minimal detail. Conclusion: If the product does not suit you, refunded or exchanged => zero risk.
