Super solution for cable free.

The tightly integrated battery lasts min. 7, hours of audio playback through and recharges via USB in 2 hours completely on.

In my case, it is relatively unimportant, since I the device beitreibe while it loads - so to speak with USB power adapter.

The operation is otherwise as simple as you possibly can:
The Mini jack the transmitter is (in my case, a television) connected to an audio playback device and this audio signal is then the Bluethooth A2DP protocol to a Bluetooth speaker (or whatever for a Bluetooth device) transfer where you will hear the corresponding sound can.

The fields of application for a transmitter are indeed obvious: But all this does not sound output via Bluetooth can although one would like.
This can also be an older iPod Nano, which is to be connected to the car radio or a TV that is to output its sound on headphones.
Quickly, easily and efficiently on realizing.

The sound is very good (depending on the quality of the origin) and of course in stereo!

The transmitter has said as a mini jack and comes with an adapter cable to RCA and USB to micro-USB charging cable.

From the size of the transmitter would probably fit in a matchbox, but weighs only 13 grams and can thus be so very good at hiding.

All in all, highly recommended the transmitter if you need something like this - please do not confuse with a Bluetooth receiver.
