How to use

Charge the case and earphones using the supplied USB‑C cable before first use. Remove the earbuds from the case to power them on and pair with a Bluetooth 5.1-compatible device; follow on-device prompts to connect. Use touch controls on the earbuds to play/pause audio, skip tracks and answer or end calls. After use, return earbuds to the charging case to recharge and extend total runtime with the case's power bank function.

Recommendations

Use silicone tips that best fit your ear canal (S, M or L) for optimal sound isolation and secure fit. Avoid submersion — IPX5 protects against splashes and sweat but not full immersion. Charge regularly and store the earbuds in the case to maintain battery life and ensure they are ready for use.
