ADAPT E1 - Leaving the Bluetooth range
The range between the earbuds and the connected Bluetooth device is device dependent. The transmission range largely depends on environmental conditions such as wall thickness, wall composition etc.
With a free line of sight, the transmission range of most Bluetooth devices is up to 30 meters.
If the audio quality gets worse or the link breaks down completely, re-enter the radio range of the Bluetooth device. The connection is re-established automatically.
If you leave the earbuds on your desk and there is no audio signal, the earbuds will automatically go to low power mode to conserve battery.
