How is the EVO II different from a normal true wireless earbud?

It hangs on an over-ear hook and rests outside the ear canal instead of sealing it with a tip. That means less isolation and less bass, but more awareness and no in-ear pressure.

Will it stay on during running?

The hook wraps over the ear, which is generally more secure than a tip-only fit for many people. Fit still varies with ear shape, so check the hook sits snugly before hard use.

Does it block noise on a plane or train?

No. The open design lets ambient sound in, so engine and track noise come through. It is a poor choice if isolation is your priority.

Can I use it for calls?

Yes, it is a headset design aimed at everyday listening and calls. The open fit keeps your own voice natural, but loud surroundings will bleed into the microphone.

What comes in the box?

Expect the ear hook headset and a charging cable. Check the listing for the exact included accessories.

Is the EVO II worth it over the original EVO?

If you already own the original and it fits well, the upgrade case is mainly about refinements rather than a new category. Buyers new to open-fit hooks get the core benefit either way.
