Do these glasses block out noise?

No. They are open-ear, so your ears stay open to traffic, wind and people around you. That is the point for outdoor sport, but it means loud environments can overpower the audio.

Can I wear them with wet or sweaty hands?

Yes. The touch controls are designed to respond with wet hands, so you can change tracks mid-run without drying off.

Are the lenses polarized?

Yes. The silver mirror lenses are polarized, which reduces glare from roads, water and bright sky.

Can other people hear my music?

Some sound escapes from the open speakers. At high volume in a quiet place, people close by may hear it.

Do they work for calls?

They are Bluetooth eyewear with built-in speakers and a microphone, so they pair with a phone for audio and calls. Sound quality on calls depends on wind and background noise.

How do they compare with Ray-Ban or Bose audio glasses?

The Octane is aimed at sport: polarized lenses, a secure athletic fit and wet-hand controls. Ray-Ban and Bose models lean more toward everyday style and music fidelity, so pick based on whether you want a workout pair or a daily pair.
