Frequently Asked Questions - BT-330 DEXP
How do I pair the DEXP BT-330 earphones with my smartphone?
Remove both earbuds from the charging case; they will automatically enter pairing mode. Enable Bluetooth on your smartphone and select 'DEXP BT-330' from the list. If they do not enter pairing mode automatically, press and hold the multifunction button on both earbuds for 5 seconds until the LED flashes red and blue.
How do I control music playback and calls?
Use the touch controls on the earbuds. A single tap on the right earbud plays or pauses music; a single tap on the left earbud answers or ends a call. Press and hold the right earbud to increase volume, and the left earbud to decrease volume. Double-tap either earbud to activate the voice assistant.
How do I charge the earphones and the charging case?
Place the earphones inside the charging case; they will begin charging automatically. Connect the case to a power source using the included Micro USB cable. A full charge takes about 1.5 hours for the earphones and about 2 hours for the case. The LED indicators on the case show the charging status.
How long does the battery last on the DEXP BT-330?
The earphones provide up to 4 hours of music playback on a single charge. With the charging case, you can extend the total listening time to approximately 16 hours. Actual battery life varies depending on volume level and audio content.
Are the earphones water-resistant?
Yes, the DEXP BT-330 earphones have an IPX4 rating, which means they are resistant to water splashes and sweat. They can withstand light rain, but do not submerge them in water or expose them to heavy moisture. Always dry them after use.
Can I use the earphones with a computer or TV?
Absolutely. The earphones support Bluetooth 5.0 and can connect to any Bluetooth-enabled device, including laptops, tablets, smart TVs, and game consoles. Simply put the earphones in pairing mode and select them from the device's Bluetooth settings.
What should I do if one earbud is not working?
First, check that both earbuds are charged. Re-pair the earphones: delete the Bluetooth pairing on your device, place both earbuds in the case, close the lid for 10 seconds, then open and re-pair. If the issue persists, perform a factory reset by pressing and holding the touch area on both earbuds for 10 seconds.
How do I reset the DEXP BT-330 earphones?
To reset, place both earbuds in the charging case and close the lid for 10 seconds. Then take them out and simultaneously press and hold the touch area on both earbuds for about 5 seconds until the LEDs flash red and blue. This clears all pairing information and restores factory settings.
Can I use only one earbud for calls or music?
Yes, you can use either earbud independently for stereo or mono operation. When using one earbud, keep the other safely in the case. The active earbud will handle audio playback, calls, and voice assistant functions normally.
How should I clean and maintain the earphones?
Wipe the exterior with a soft, dry cloth regularly. Remove the ear tips and rinse them with warm water, then let them dry completely before reattaching. Avoid using alcohol or harsh solvents as they may damage the silicone. Keep the charging contacts clean and dry.
