Its 40 mm drivers reproduce sound across a wide 20 to 20,000 Hz range, with a sensitivity of 115 dB. The headset supports the A2DP, AVRCP, HFP and HSP profiles and pairs wirelessly with smartphones, tablets and other Bluetooth devices within a range of up to 10 metres.

The built-in microphone, rated at -42 dB sensitivity with a 20 to 16,000 Hz frequency response, keeps your calls clear. A 200 mAh battery is rated for up to 25 hours of continuous use. When you prefer a wired connection, you can use the 3.5 mm jack or the USB-C charging port.
