Do these work with Android phones?

Yes, any device with a USB-C port that supports USB audio, including most recent Android phones. Some phones without a headphone jack still route audio over USB-C fine.

Do they work with iPhone?

Yes, on iPhone 15 and later models with a USB-C port. Older Lightning iPhones need a different version or an adapter.

Do they have a microphone?

Yes. The inline remote includes a microphone plus volume, play/pause and answer/hang-up buttons.

Do they need charging?

No. They draw power over the USB-C cable, so there is no battery and no charging case.

Are they good for running or the gym?

Not ideal. They are listed as not suitable for training, the hard tips can loosen with movement, and the cable gets in the way.

What comes in the box?

The earphones with their fixed USB-C cable and a storage case. There is no adapter, no charging case and no spare tips, since the tips are molded into the housing.
