I’ve been using my Shure SE 535 with the newest Bluetooth cable for the past couple years. Incredible sound isolation so my fans and drivetrain noise are a non-issue. Sweat has not been a problem at all. I use the black foam tips, but if none of the standard tips work for your anatomy, you can have an audiologist mold tips specifically for you.
I also own Bose QC35ii and like them for what they are, but would never wear them on the trainer due to heat and sweat.
