Excellent bluetooth device!

Regarding the seller, no problem!
The delivery was done very quickly and very properly protected product.
Now about the product:
The use of the module is done rather simply.
As described in the product it is possible to use the product as quémetteur or as a Bluetooth receiver.
Small note, however, here is either one or the other, the device is not intended for use in 2 directions simultaneously.
And to confirm this protocol, the jack used to transmit or receive sound is unique.
This is the mode selected when starting the device will choose the "meaning" of operating the jack and Bluetooth module.
In receiver mode, it turns any auxiliary input on an amp or a stereo A2DP-compatible Bluetooth audio broadcaster. May have even plug in any wired headset to transform bluetooth stereo headphones (not in headset, micro function is not implemented).
In transmit mode, any kind headphone output, line out, or whatever is the type of low power can be used to be "streamed" in Bluetooth to any Bluetooth headset or another type of module configured in receiver mode.
This is for example what I do between my TV and my bluetooth headsets to active noise reduction, can watch TV without disturbing those around me or overnight to let people sleep at home.
Pairing is easy and reliable, but it will still pay attention to a detail in transmitter mode.
The module can only be paired with devices with keys dappairage equal to "0000", "1111", "8888" or "1234".
The range is very reasonable although I've had cameras in hand most powerful on this aspect but it captures the signal really far despite several obstacles between the headset and the module.
The battery that the team is great in terms of autonomy and you can count on it for long listening period.
Recharging via micro-USB is super convenient because any cable (including one supplied) connected to a 5V source may be used for recharging; See the phone charger directly exercising the same connector.
A great product that I know too that you recommend, the only worries I board found him being that it does not include the type of cable 3.5 mm Jack / Double RCA (White / Red), although there Jack has a 3.5mm / 3.5mm jack and a USB cable / Micro-USB.
The package does not include either of charger, and I am a little surprised given the price not too surprised given the quality.
I am anyway very satisfied and a second control module for my brother who is also enamored of the concept.
