This bidirectional Bluetooth Audio interface offers many wireless connection possibilities. It is battery operated and benefits from an extremely compact design. Its clever design is capable of acting as a transmitter and receiver respectively, making it an ideal accessory for enjoying Bluetooth Audio connectivity in all circumstances. For example, it can be used to connect a wired headphone to a remote device. The interface is capable of acting as a Bluetooth transmitter and receiver respectively. Two simultaneous connections can be made in order to link several devices of different types.

Intuitive and ergonomic

In spite of the many features offered, the device is very easy to use.  Simply connect the 3.5mm jack port to the device you wish to extend connectivity to. A sliding button on the side of the housing is used to configure the interface in either the transmitter (Tx) or receiver (Rx) position.

In receiver mode (RX) the interface will receive from an external source (cell phone, tablet, file reader...) the digital audio stream, decode it and send it in analog form to the 3.5mm jack port or digital in Toslink Optical format. The uses of the receiver mode are as numerous as they are varied: using a fixed source without sacrificing mobility, connecting speakers that are difficult to access or in a more trivial way, listening to and controlling the music on your phone without having to manipulate it. 

In Transmitter (TX) mode the interface samples any analog audio signal submitted to its 3.5mm Jack or Toslink Optical port and transmits it via Bluetooth to paired devices.

Either way, the device supports apt-X and apt-X HD standards to enjoy the best compromise in audio quality and listening comfort.

The device benefits from extensive connectivity. Thus, Bluetooth, 3.5mm jack and Toslink Optics can be connected and disconnected. 

Easy to carry

The device is equipped with a 160mAh lithium-ion battery. It provides approximately 18 hours of activity in transmission and reception. Charging is easy thanks to the presence of a 5V micro-USB port. Charging takes approximately two hours. Its advantageous dimensions (square of 4.37 side x 1.9 cm) for only 22g make it a comfortable object to carry that can be easily forgotten.

Pairing with model of the same type

If none of your remote devices have Bluetooth connectivity, you can use two such interfaces to pair them together. In this configuration, any device with an analog input/output can be used for remote connectivity.  This solution can bypass many integration problems.
