Product information

Description

Wireless Bluetooth headset designed for active lifestyles. The earbuds are shaped with attention to ear anatomy to provide a secure fit that feels lightweight while staying fixed in place. The set includes a storage and charging case with a 300 mAh capacity that protects the earbuds during transport and provides additional charging on the go.

Advantages

Ergonomic in-ear design ensures comfortable long-term wear and stable fit during movement. Built-in microphone and multifunction control button on the earphones allow hands-free calls and easy media control. Compact charging case both stores and recharges the earbuds, extending usable time away from a power source.

Key specifications

  • Connection: Bluetooth wireless
  • Charging case capacity: 300 mAh
  • Battery life (earbuds): up to 4 hours
  • Operating range: up to 10 m

How to use

Take the earbuds out of the charging case and they will enter pairing mode. Enable Bluetooth on your device, select the headset from the available devices list, and confirm connection. Use the multifunction button on the earphones to answer or end calls and to control playback. Return the earbuds to the charging case after use to recharge them and store them safely.

Recommendations

Charge the case before first use. Keep the charging contacts clean and avoid exposing the earbuds and case to moisture. For best fit, insert each earbud so it sits comfortably and securely in the auricle.
