1. Avoid leaving the earbuds unused for long periods. To protect battery health, use or charge them at least once a month. Extended over-discharge can significantly reduce battery life and overall performance.

2. To better protect battery health, it is recommended to charge the earbuds before the battery drops below 20%, or before they power off automatically.

3. Do not let the charging case stay in a low or 0% charge state for long periods.

4. Clean the charging pins on the earbuds and case, speaker outlet, microphone holes, rear cavity vents, and ear tips promptly after use (we recommend cleaning charging pins with alcohol swabs or cotton cloth at least 1 - 2 times per month).

5. Keep the earbuds in a dry place. If they come into contact with liquid, dry them using a hair dryer on a cool setting.
