Specifications are subject to change without notice.

There are other WiFi 2.4G and Bluetooth devices in the use environment, 

which is prone to interference, which may lead to unsuccessful connection, 

or sound freeze, or even interruption of playback.

Bluetooth also affects effective transmission due to too long a distance or 

being blocked by a block (such as a wall). It is recommended that the 

straight-line distance for obstacles is generally about 8-10 meters.

For some Android mobile devices, Bluetooth may not be fully compatible, 

which may result in abnormal playback. Please confirm that there is no 

compatibility issue with the mobile phone before use.
