For optimal fit and to prevent displacement during vigorous swimming, consider wearing a swim cap over the headphones.
Maintenance
Cleaning
- After use, especially after swimming or intense exercise, rinse the headphones with clean fresh water.
- Wipe the headphones dry with a soft, clean cloth.
- Do not use abrasive cleaners or solvents, as these can damage the waterproof seals and materials.
Storage
- Store the headphones in a cool, dry place away from direct sunlight and extreme temperatures.

Water Resistance
The Hostena SwimBeats X16 headphones are IP68 rated, meaning they are protected against continuous immersion in water up to 2 meters deep. This rating ensures protection against dust, sweat, and rain. However, it is important to:
- Ensure the charging port is dry before connecting the magnetic charging cable.
- Avoid exposing the headphones to saltwater for extended periods without rinsing, as salt can cause corrosion over time.
- Do not intentionally submerge the headphones beyond the specified depth or duration.
