IP54 Water Resistance
The Picun H3S headphones feature an IP54 waterproof design, providing effective protection against sweat and splashes. This makes them suitable for various activities, including:

- Outdoor activities
- Everyday use, even in light rain
While they are water-resistant, it is important to note that they are not designed for submersion in water. Avoid prolonged exposure to heavy rain or direct water jets.

Troubleshooting
Connection Issues
- Headphones not pairing: Ensure Bluetooth is enabled on your device and the headphones are in pairing mode (usually indicated by a flashing light). Try turning Bluetooth off and on again on your device.
- Frequent disconnections: Ensure the headphones are within the effective Bluetooth range of your device (typically 10 meters/33 feet). Avoid obstacles that might interfere with the signal.
- Only one earbud connecting: Place both earbuds back into the charging case, close the lid, wait a few seconds, then take them out again to re-establish the connection.
Battery & Charging
- Headphones not charging: Ensure the charging cable is securely connected to both the case and a power source. Check if the charging pins on the earbuds and in the case are clean and free of debris. The LED display on the case should indicate charging status.
- Short battery life: Ensure the headphones and charging case are fully charged before use. Reduce volume levels, as higher volumes consume more power.
Sound Quality
- Low volume or poor sound: Ensure the headphones are correctly positioned on your ears, with the sound port aligned towards your ear canal. Adjust the volume on both your device and the headphones.
- Distortion: Reduce the volume on your device. Ensure there are no obstructions between the headphones and your device.
