Recommendations

Use the supplied ear tips to achieve a snug, noise-isolating fit; this improves sound quality and stability during exercise. Avoid prolonged exposure to high volume to protect hearing.

Charge the device fully before extended use and follow local regulations for safe disposal of batteries.
