- Search for available devices and select "EW310" from the list.

Operation
Basic Controls
The Lecoo EW310 earphones feature touch controls for various functions. While specific touch gestures are not detailed, common functions typically include:
- Play/Pause: Single tap on either earbud.
- Answer/End Call: Single tap on either earbud.
- Next Track: Double tap on the right earbud.
- Previous Track: Double tap on the left earbud.
- Activate Voice Assistant: Triple tap on either earbud (if supported by your device).
- Volume Control: The product specifications indicate volume control is supported. This is typically managed via your connected device or specific touch gestures (refer to the quick start guide if included for exact gestures).
Single Earbud Mode
Thanks to the dual host transmission, you can use either the left or right earbud independently. Simply take one earbud out of the case, and it will automatically connect to your paired device. The other earbud can remain in the case or be used by another person (if paired separately, though typically only one earbud connects to a single device at a time for audio).
