Headphone/Speaker/Receiver No Sound and Not Working - General

Check Point 1: Have you Connected/Paired it Properly?
Check on your device Bluetooth device list, it should say "Connected" on the menu. If not, please try to pair it to your device again.

Check Point 2: Have you been Switching between APPs?
Sometimes when you're listening to music and a call comes in, the Headphones/Speaker can have issues switching back-n-forth... this is a common Bluetooth issue and happens to every Bluetooth Headphone/Speaker. 
Please choose the headphone/speaker again (if applicable) or reboot the headphone/speaker and pair them up again.

Check Point 3: Have you Charged the Headphone/Speaker?
This might seem like a simple solution but when the device is low on battery, a wide variety of issues may occur. Please make sure that it has sufficient battery level.

If you've checked everything above but still no sound, please try the methods below.

Method 1: Try it on a Different Device.
If you have another phone, another laptop etc... try to connect the Headphone/Speaker to it and see if it works on the other device. 
If yes, it's probably something to do with the settings on your original device, please try again.
If no, please contact us for support, you may have a faulty unit.

Method 2 (For Laptops/Computers): Check the Audio Settings.
For Windows, go into Sound Settings and Sound Control Panel. For Mac, go into Sound Preferences.
Make sure that the Headphone/Speaker you'd like to use has been selected as the Audio Output/Input device.
If you're using a Meeting Software such as Skype or Zoom, you may need to go into the app itself and adjust the settings in there as well.

Method 3: Factory Reset.
If none of the methods above work, please factory reset the Headphone/Speaker and pair again. Please remember to delete the Avantree device from the paired Bluetooth device list on our sound source device, before attempting to pair again.

If factory reset still can't get it to work or if you have any more questions or need further assistance, feel free to contact us at support@avantree.com
