This is an all-time low for the OpenMove, which originally sold for $100 -- and actually one of the best deals on record for any AfterShokz headphone.
These things are hugely popular with runners and bikers, as they allow you to comfortably listen to music, podcasts and the like without blocking ambient noise. That means you're less likely to miss hearing, say, an oncoming truck, which a noise-canceling earbud might block out.
I'm a fan, and my super-active brother-in-law Bill will talk your ear off about AfterShokz if you let him. "Literally life-changing," he tells me often.
Note that at this writing, all four colors are on sale at this price, but are showing "out of stock" for a few days. Thankfully, you can still get your order in.
