It works & what is handy.

In the first tests, the couple Transmitter / Headset & not working so I sent this comment:
1) Pairing with my bluetooth headset it's done without problems, which was not the case with all the devices I tried to pair him. The sound is fine. After first use, the next day I will retry the blow> Nothing. No sound.
I recharge helmet & Transmitter & I retries> Still nothing. So I do not know exactly what is happening [If we réappairer whenever the headset so the sound goes, it would be a nonsense ... If there is a special procedure (?) ... ] but I consider that once paired, Bluetooth devices must operate with batteries charged. I left the transmitter plan for now, I do not have time to fool around to look where the bug is. Perhaps a prior single bluetooth escapes me, I do not know, I am not a technician does not account & become a pro bluetooth. I buy a product, I'm the manual, I would expect it to work. Perhaps this come from the helmet?
In the end, my opinion on the issue as a customer is that the operation of this transmitter should be more transparent. I followed the procedure manual & it worked well at first use, why not the 3rd as the two aircraft were recharged?
Now if a technician explains why / how, I'm interested ...
Apart from all this, which is already sth, the basic idea of ​​this transmitter is very interesting. If only he refonctionnait ...

2) Sunvalley sent me a 2 Transmitter & I now have a bluetooth headset TaoTronics TT-BH03. The combination of both works fine. Sunvalley thank you.
