Many Teufel products in the Bluetooth category also feature aptX®. What does aptX® mean?
The addition aptX® identifies a codec for audio signal transmission via Bluetooth. The special feature of this technology is that an audio signal is compressed - as required by wireless transmission - but the audio signal after decompression shows hardly any loss compared to the original track.
You should pay attention to the following
Both devices, i.e. the transmitter (e.g. smartphone) and the receiver (e.g. Bluetooth box) must support Bluetooth with aptX® codec. Before buying a device, you should look for the aptX® symbol or the manufacturer's specifications in the technical data. If both devices support aptX®, the user simply has to connect the devices. The integrated codec will now start on its own. So it doesn't get any more practical than this.
