Reliable and easy-to-use True Wireless earbuds. Control your music and calls simply by tapping the earbuds, customize them to match your outfit, and enjoy 30 hours of music without cables. True Wireless is the next level of wireless listening. Connect your Twins Core via Bluetooth to your device and listen using just the earbuds. No wires. Since both earbuds have a built-in microphone, you can use them not only as a pair but also individually (just the right or the left one).
