Waterproof Usage Guidelines (IPX8)
The ANSTEN S950 headphones are IPX8 waterproof, meaning they can be submerged in water up to two meters deep for up to one hour. They are suitable for swimming, surfing, and other water activities.
- For Underwater Use: Always switch to MP3 mode before entering water. Bluetooth signals do not transmit effectively underwater.
- After Water Exposure: Ensure the charging port is completely dry before connecting the magnetic charging cable to prevent damage.
- Earplugs: Use the provided silicone earplugs for an enhanced audio experience while swimming, as they can help block out water noise.
