I own the original branded Aftershokz and still like really them, few years in ownership now.

Bought my wife the newer branded Shokz and the only difference I noticed was a slight shape change and the connector went proprietary from the USB C on mine.

She runs as a hobby and prefers them to other in/over ear styles.

They're very handy being open ear to oncoming sounds toward you or someone trying to get your attention.

I was amazed what the bone conduction produces in sound. Not great super high fidelity but impressive nonetheless
