The unit itself is very simply decorated, a RX / TX switch to toggle the mode, a single 3.5mm stereo jack socket, which serves both as an input and as an output, plus a charging socket. Slightly larger than a matchbox, but flatter. For a size comparison I placed the next time an iPod Classic.
Included in addition to a very limited useful operating instructions in English and German 2 adapter cable for the audio signal - even at 3.5mm, once on 2x cinch, and a charging cable to the necessary hollow plug at one end and a USB A connector on the other side ,
Pairing works without problems, with the long press (about 7 seconds) of standby let out for pairing mode be guessed from the manual. As a transmitter, he has grabbed the nearest BT receiver is in pairing mode, already ran the whole thing. A later test with another receiver (ie, the second partner) ran without any problems.
In Test my iPod Classic was allowed on the device in transmit mode to send to the stereo - an application that will happen here now quite often after DLNA is rather unwieldy on my devices run at the size of my music collection and AirPlay by the need the computer to leave, was not as convenient. With increasing capacity of mobile music players and smartphones no longer so relevant, but at least for now the 160GB iPod are still very practical and easy to join now with the system.
At the sound quality can not be faulted, clear, detailed, no noise. The counterpart is incidentally also a very effective receiver with built-in power supply, the entire chain speaks well "only" A2DP, but it sounded neat.
The opposite direction, I have only briefly tested with a boombox, again no problems and a decent sound quality.
What is certainly more interesting - apparently can not load all the products at once and their BT-functionality - with this device that folds easily, I have in the middle connected the charger both in reception and in station operation and everything went on as expected.
Incidentally, I once had looked at the latencies because of the desire to connect musical instruments wirelessly to the stereo, is still present, but Bluetooth is not as definitely the way. Due to the technically necessary buffering there are latencies of 100ms more appreciated, as this device can change anything. In order to play "live" an instrument is virtually impossible.
Overall - perfect for retrofitting non-Bluetooth enabled sound sources, the receiver role works fine, which extends the range a bit, just by the design and the weight does that well in the pocket on the go.
