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