Maintenance
To ensure the longevity and optimal performance of your Mifo O5 Plus Gen 2 earbuds, follow these maintenance guidelines:
- Cleaning: Regularly clean the earbuds and charging case. Use a soft, dry cloth. For stubborn dirt or stained contacts, lightly dampen a cotton swab with alcohol and gently wipe the charging contacts on both the earbuds and inside the case.
- Storage: Store the earbuds in their charging case when not in use to protect them and keep them charged. Avoid extreme temperatures (below -15°C or above 55°C).
- Water Exposure: While IPX7 water-resistant, ensure earbuds are dry before placing them back in the charging case to prevent damage to charging contacts.
Troubleshooting
Here are solutions to common issues you might encounter:
- Earbuds cannot be charged normally? After prolonged use, contacts may become stained. Clean the charging contacts of both the earbuds and the case with alcohol and cotton. If the earbuds flash red when placed in the case, charging is normal.
- Intermittent signal? Wireless earbud signals can be affected by weather, network stability, mobile phone model, and distance. To resolve, clear the Bluetooth pairing name of the device and reset the earbuds.
- Pairing fails? In the rare event that pairing fails, attempt to initiate a reset. Press and hold the power button on either earbud for 8 seconds until the indicator flashes pink and purple.
