Supported audio formats include MP3 and WAV.
The IPX8-rated construction is designed for swimming and water-based exercise.

After swimming:
Rinse the headphones gently with clean fresh water.
Dry them thoroughly using a soft cloth.
Allow the charging contacts to dry completely before charging.
The exact permitted depth and immersion time should follow the manufacturer’s instructions.
Bluetooth 5.4 provides a stable, energy-efficient wireless connection with compatible smartphones, tablets and other audio devices.
