Cautions

2. Do not connect the full-charged headset to the charging circuit for a long time. Overcharging will shorten battery life.
3. Please keep the headset battery safe. Do not put the battery or the headset into fire or water to avoid explosion.
4. Do not use headset with high volume for extra long time, which may cause hearing loss. Always listen at a moderate level.
5. Don’t charge with high voltage device, which may cause damage to the headset. 6. Make sure that the headset is fully charged before using it if unused for a long time.
6. Lifetime of the battery will be significantly reduced if your device is left uncharged for a long time. We therefore recommend that you recharge your device at least once a year.
7. Please reset the headset if it cannot work well.
