Hearing safety

High volume can damage hearing. Begin at a low volume, use the lowest comfortable level, and limit prolonged listening. Do not use earphones where reduced awareness of traffic, alarms, instructions, or surroundings could create a hazard.

Water, cleaning, and children

Water resistance varies by model and does not mean the product is suitable for immersion or charging while wet. Clean with a soft, dry cloth and keep charging contacts dry. Earphones and small accessories can present a choking hazard and should be kept away from young children.

Wireless use and medical devices

Follow posted rules for Bluetooth devices in aircraft, healthcare facilities, and restricted environments. If you use a pacemaker or other medical device, follow the device manufacturer's separation and wireless-use instructions.
