Common questions about manuals, registration, and support for this brand.
Take the earbuds out of their charging case; the lights should flash to indicate they are automatically pairing with each other. Once synced, open your smartphone's Bluetooth settings, search for your earbuds' model name (e.g., GT27), and tap to connect.
Touch controls vary slightly by model, but generally: tap once to play/pause or answer a call, tap twice to switch tracks, and tap three times or hold for 3 seconds to summon your device's voice assistant. Please consult your specific product manual for exact control mappings.
Many YOSINT earbuds, such as the Bluetooth 5.0 headphone models, feature IPX7 sweat- and water-resistant nano-coating. This protects them from sweat during workouts and light splashes, but they should not be submerged in water. Always check your specific model's manual to confirm its IP rating.
First, check if both earbuds are fully charged. If they are, place both back into the charging case and take them out simultaneously to force them into pairing mode. You may also need to 'Forget' the device in your phone's Bluetooth settings and re-pair them as a fresh connection.
