Question about Shokz OpenSwim

Hi, as far as I know, Bluetooth technology does not work underwater (for physical reasons, the water is too dense).

I keep reading that the Openswim USB connection to the MAC does not work optimally. Does anyone have any experience with this?
I have a MacBook Air and don't want to bother myself with it ;-)
Thanks in advance.

HIFI Walker T10 Air, unfortunately not available from digitec, has both Bluetooth and an (8x larger) memory for MP3 or other audio files. When submerged, the Bluetooth connection is of course interrupted, but you can switch to a randomly selected file in the memory at the touch of a button. The sound is much stronger under water, the head acts as a sound box. I wonder if that's why other bathers looked at me so strangely when I came up for air?

I bought Bluetooth headphones some time ago - for swimming. Doesn't work, Bluetooth is interrupted under water.
But it works in the shower... 😉

Now I have the Shokz OpenSwim - they're not as "sexy" when it comes to putting music in them (just like before, with connection to a computer 🤓), but they work great under water.
