Features in detail
Bluetooth 5.3
Newer Bluetooth pairs quickly and holds a steady connection up to about 10 metres, with good audio stability for music and calls.
Open-ear stereo speakers
The speakers sit by your ears without sealing them, so you keep hearing traffic, people and the environment, which is safer outdoors than in-ear earphones.
Hands-free calling
A built-in microphone lets you answer and make calls without taking out your phone.
UV-protective lenses
The tinted lenses shield your eyes from strong sunlight during outdoor activities.
Universal compatibility
No app is needed: they work like any Bluetooth headset with phones, tablets and laptops.
About 4 hours of music
A full charge covers a long drive or an afternoon outdoors, and recharges in 1.5–2 hours over USB (DC 5V).
Compatibility
They pair over Bluetooth with any modern iPhone or Android phone, and also with tablets and laptops that support Bluetooth audio. Cadence does not translate and has no app. Prescription lenses cannot be fitted.
Setup and use
- Charge the glasses fully with the included USB cable (1.5–2 hours).
- Switch them on and hold until they enter pairing mode.
- Select them in your phone's Bluetooth menu.
- Play music or take calls as with any Bluetooth headset.
- Switch them off after use to save battery.
Care and maintenance
Wipe the lenses with the included microfibre cloth; avoid paper tissues, which can scratch the coating. Keep the charging contacts clean and dry before charging, store the glasses in their bag when not worn, and do not leave them on a car dashboard in direct sun, as heat shortens battery life. Rinse off salt water or heavy sweat with a damp cloth rather than running water, and never submerge them.
