Can I use these sunglasses for prescription lenses?

No, the lenses are non-prescription and not designed to be replaced with prescription lenses. You would need to wear contact lenses or have prescription inserts made by a specialist.

How long does the battery last on a full charge?

The exact playtime is not specified, but the manufacturer notes the headset must be charged once a month even if unused. Expect a few hours of listening or talk time per charge, typical for small Bluetooth speakers.

Are these sunglasses waterproof?

There is no official water-resistance rating. They are not waterproof, so avoid wearing them in heavy rain or while swimming. Sweat may also affect the electronics over time.

Do they work with both iOS and Android?

Yes, they use standard Bluetooth and should pair with any Bluetooth-enabled phone or tablet, including iPhones and Android devices.

Can I replace the lenses with different colors?

The lenses are not described as interchangeable. The detachable temples allow you to use the frames as regular glasses, but swapping lenses is not mentioned as a feature.

Is the sound quality good for music?

Sound is adequate for casual listening and calls, but bass is limited and audio may leak at higher volumes. They are not designed for critical music listening.
