How do these compare with regular in-ear earbuds?

They sit outside the ear canal on a hook, so nothing presses inside your ear. You get more comfort and awareness but less bass and isolation than sealed in-ear buds.

Can I wear them with glasses or a helmet?

The titanium hook wraps behind the ear, so it can sit alongside glasses arms. Fit varies by ear shape, and a helmet strap may press on the hook.

How long does the battery last?

Up to 6 hours on a single charge, with four full recharges in the case for up to 48 hours total. Call time and volume will shorten that.

Do they block noise on a plane or train?

No. The open design lets ambient sound in and there is no active noise cancellation, so they suit awareness more than quiet listening.

Are they good for running?

The light weight and hook shape keep them stable, and the open fit lets you hear traffic. No water or sweat resistance rating is stated, so treat them as not sweat-proof.
