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. Although the headphones are IPX4-rated, avoid submersion and rinse with a damp cloth after exposure to heavy sweat or dirt. Charge the device fully before extended use and follow local regulations for safe disposal of batteries.
