Pairing with a Device
The Picun W20 earbuds feature a Hall Switch for fast pairing.

- On your device (smartphone, tablet, etc.), enable Bluetooth and search for available devices.
- Select "Picun W20" from the list of found devices.
- Once connected, you will hear a confirmation tone, and the earbuds will be ready for use.
- Subsequent Pairing: After the initial connection, the earbuds will automatically connect to the last paired device when you open the charging case lid, provided Bluetooth is enabled on your device.
The Bluetooth range is up to 50 feet (approximately 15 meters).
Wearing the Earbuds
For optimal sound quality and comfort, choose the correct ear tip size and ensure a secure fit.
- Select the ear tips (S, M, L) that best fit your ears. A good seal is crucial for bass performance and noise isolation.
- Gently insert each earbud into your ear canal.
- Rotate the earbud slightly until it feels secure and comfortable.
It is recommended to take off the earbuds every 2 hours to allow your ears to relax.

Maintenance
Cleaning
Regular cleaning helps maintain sound quality and hygiene.
- Gently wipe the earbuds and charging case with a soft, dry, lint-free cloth.
- Remove ear tips and clean them with water and mild soap if necessary. Ensure they are completely dry before reattaching.
- Use a cotton swab or a small, soft brush to clean the charging contacts on both the earbuds and the case.
- Avoid using abrasive materials, alcohol, or chemical cleaners.
Water Resistance (IPX8)
The Picun W20 earbuds are IPX8 waterproof, meaning they are protected against continuous immersion in water beyond 1 meter. This makes them suitable for sports and exercise, resisting sweat and rain.
- Do not intentionally submerge the charging case, as it is not waterproof.
- Ensure earbuds are dry before placing them back into the charging case to prevent damage to the charging contacts.
- IPX8 rating applies to fresh water. Exposure to salt water, chlorinated water, or other liquids may cause damage.
Storage
When not in use, store the earbuds in their charging case to protect them and keep them charged.
- Store in a cool, dry place, away from extreme temperatures and direct sunlight.
- Avoid dropping or subjecting the earbuds and case to strong impacts.
