4. Wearing the Headphones

Proper fit is crucial for both sound quality and waterproof performance.

1. Select Ear Tips: Choose the appropriate ear tips. Use the dual-layer swim earbuds for water activities to create a waterproof seal. For land use, the single-layer earbuds offer comfort.
2. Positioning: Place the ear hooks over your ears. Gently insert the earbuds into your ear canals, ensuring a snug and comfortable fit.
3. For Swimming: To enhance the waterproof seal and secure the headphones, it is recommended to wear a swim cap over your ears and the headphones.

5. Operating Modes

The MTYBBYH S25 headphones support two primary operating modes: Bluetooth for land use and MP3 for underwater use.

5.1 Bluetooth Mode (For Land Use)

Bluetooth mode allows wireless connection to your smartphone, tablet, or other Bluetooth-enabled devices.

1. Power On: Press and hold the Power button until the indicator light flashes (usually blue/red alternately) to indicate pairing mode.
2. Pairing: On your device, enable Bluetooth and search for "MTYBBYH S25". Select it to connect. Once connected, the indicator light will typically show a steady blue light or flash slowly.
3. Controls: Use the integrated buttons on the headphones for playback control (Play/Pause, Volume Up/Down, Next/Previous Track) and call management.

Important: Bluetooth signals do not transmit effectively underwater. Always switch to MP3 mode for swimming or diving.

5.2 MP3 Mode (For Underwater Use)

The built-in 32GB MP3 player allows you to enjoy music without a connected device, ideal for underwater activities.

1. Transferring Music:
   • Connect the headphones to your computer using the USB magnetic charging cable.
   • The headphones will appear as a removable disk drive.
   • Drag and drop your MP3, WMA, APE, or FLAC audio files directly into the headphone's storage.
   • Safely eject the device from your computer before disconnecting the cable.
2. Switching to MP3 Mode: (Specific button press or sequence to switch modes, e.g., double-press the Power/Mode button). Refer to the quick start guide for exact button functions.
3. Controls: Use the integrated buttons for playback control (Play/Pause, Volume Up/Down, Next/Previous Track).

6. Waterproof Usage Guidelines

The MTYBBYH S25 headphones are IPX8 rated, making them suitable for swimming and other water sports. Follow these guidelines for optimal performance and longevity.

1. Activate MP3 Mode: Always ensure the headphones are in MP3 mode before entering the water. Bluetooth connectivity is not effective underwater.
2. Secure Fit: Use the dual-layer swim ear tips and ensure they form a tight seal in your ear canals. Wearing a swim cap over the headphones can provide additional security and seal.
3. Depth and Duration: The headphones can withstand submersion up to 8 meters (26 feet) for a maximum of 6 hours. Avoid exceeding these limits.
4. Post-Swim Care: After use in chlorinated water, saltwater, or sweat, rinse the headphones thoroughly with clean fresh water. Allow them to air dry completely before charging or storing.
