Frequently Asked Questions - BTHT-4189-BLK Avantree
How do I pair the Avantree BTHT-4189-BLK earphones with my phone?

How long does the battery last?
The earphones provide up to 8 hours of playback on a single charge. The charging case holds an additional 16 hours, giving a total of up to 24 hours. Actual battery life may vary based on volume and usage.
Can I use these earphones for sports?
Yes, they are rated IPX5 which means they are sweat and splash resistant. They are suitable for workouts and light rain, but not for submersion.
How do I charge the earphones and the case?
Place the earphones into the charging case and close the lid. The case itself charges via the included Micro USB cable. Connect the cable to a USB power source (e.g., computer or wall adapter). The LED indicators show charging status.
The earphones are not connecting to each other. What should I do?
Ensure both earphones are placed in the charging case and then remove them together. This should trigger a re-sync. If the issue persists, reset by holding the multifunction button on each earbud for 10 seconds (until LED flashes red/white), then re-pair with your device.
Are these earphones compatible with iPhone and Android?
Yes, they work with any Bluetooth-enabled device, including iPhone, Android phones, tablets, and laptops. They support standard Bluetooth profiles like A2DP and HSP.
How do I control volume and skip tracks?
The multifunction button on each earbud handles controls: Single press to play/pause or answer/end call; Double press to skip to next track; Triple press to previous track; Long press for volume up (right earbud) or volume down (left earbud).
What should I do if the earphones won't charge?
First, clean the charging contacts on the earphones and inside the case with a dry cloth. Make sure the earphones are correctly seated. Try a different charging cable and power source. If still no charging, the battery may be defective; contact Avantree support.
Can I use only one earbud (mono mode)?
Yes, you can use either the left or right earbud independently. Simply take one earbud out of the case; it will pair as a mono headset. To switch back to stereo, place both in the case and remove together.
How do I reset the earbuds to factory settings?
