The Avantree Leaf uses a Class 1 CSR chipset specified at 20m/60ft in an OPEN SPACE environment without any walls or floors in the way.

Here are some common causes of short range / audio dropping out for the Leaf.

  1. The range depends on BOTH the receiving and the transmitting device. Please test your receiving Bluetooth device with a mobile phone to confirm the range is acceptable.
  2. An UNSTABLE Bluetooth connection can cause range and audio issues. Please reset/clear the pairing history of BOTH DEVICES and re-pair/connect them again.
  1. If you've plugged the Leaf into a USB 3.0 port, please change to another (preferably non 3.0) USB port. The USB 3.0 standard has known interference issues with Bluetooth.
  2. If you're watching videos or streaming music from an ONLINE source, please make sure the audio drop out issue is not caused by slow network speed
  3. Unstable power output from the USB port can also cause range and audio issues. If you're using a desktop computer, please try a USB port on the back of the computer using the extension cable. You can also try using a USB hub with a power adapter. 

If you still have issues after trying/checking all of the above suggestions, please contact us at support@avantree.com, and let us know the issues. We'll help to troubleshoot or replace the unit for you if required. Thanks.
