enclosed my review of the product. I set photos and a video still follows.
The BT receiver is really a small dwarf. It is high-quality.
I could not detect any gaps, sharp edges or Lackpatzer.
It is managed with a plastic sheet that you can deduct. There is a round button on the top, then an on / off switch and the line out and the charging socket. I had charged him by means of external USB charger.
I have my phone in the BT mode is switched, then pressed the button on the top of the unit. Now it is ready to receive and if you look on the smartphone for new devices it is found directly.
Man can now connect via jack to 2 x RCA or jack to jack with another device. Now may be just fine, the music from the smartphone to the external device transmit and hear of this.
How long the battery holds out for that I can not say anything. But it would have to be a couple of hours
So if you looking for a solution to music from his smartphone should send to other devices via Bluetooth to look at this product times.
