Yeah, I was looking for SOMETHING different. About a decade ago I was in a Sprint store and they were promoting the 'Jawbone' which worked by using bone conduction. So, I just thought something like that had to exist in the year 2021. A Google/eBay search turned up good results.
Aftershokz is the Apple of this business market so if you try it, I'd go with them. But as with Apple, they have lower specced products. I wouldn't mess with anything other than the Aeropex. The Titanium, which is their lesser product is fairly bulky. They do have one product you can use while swimming.
Their products work well with Apple devices though. You can answer calls, pause and resume music, skip, etc. It's all integrated into the headset. The one annoying thing (and all of the products experience this) is volume. If you play volume loud, expect the set to vibrate against the sides of your cheekbones. That's how they work, it's just at lower volumes you don't feel it.
It's just a really cool alternative to traditional headsets/buds. For those that use hearing aids, the iPhone also has hearing aid apps that will leverage this via BT.
EDIT: Apparently they have changed their name to just Shokz now and renamed some of the product. The Aeropex is now the 'OpenRun' while a new release (9th generation) is 'OpenRun Pro'.
