Does the Bluetooth work underwater?

Some of the cheap ones aren't real bone conduction. After a fake pair I bought a pair of Shokz, wear them in the shower all the time, usually after getting them (and myself) sweaty.

Beware of poor fitment though. I got some cheap wired ones years ago (from Amazon), didn't work so well because they had bad contact and no mechanism for adjustment. Kinda also needed a preamp, though if contact were perfect maybe that'd matter less.

I also am not so sure I'd trust them to be waterproof, and anything that is would likely have a heftier pricetag. That, and I'm pretty tired of everything having batteries.
