How to use
Charge the earbuds and case via the USB Type-C port before first use. Open the case and remove the earbuds to power them on and initiate Bluetooth pairing; follow device prompts to complete pairing with your phone or player. Fit each earbud into the ear canal for secure intraaural coupling and adjust by testing fit and seal. Use the touch-sensitive controls on the earbuds and the touch bar on the case to change noise-cancelling levels, control playback and answer calls. For LDAC or additional settings, install and use the manufacturer’s companion app on compatible devices.
Usage recommendations
Select an ear tip size that provides a proper seal to maximise passive isolation and ANC performance. Use fast charging for short top-ups when time is limited and fully charge the case regularly to preserve overall battery availability. Enable LDAC in the companion app only on compatible Android devices when higher wireless audio bitrate is required. Clean earbud contact points and ear tips periodically and avoid exposing the charging case to extreme temperatures or moisture.
