While the bottons are small, too small by far with gloves, it’s not like I need to do more than turn it on or off while on the surface.

I tend to do dive planning the night before with full equipment checks, as part of these checks I load a play list for my dives. No need to skip any music as it’s only got what I want to hear!.

I have the first swimp3 and quite like it, but I’m hoping the new one has a slightly improved sound.

a couple of things:

if you wear earplugs while using it, you get less water noise and can hear the music better.

if you go go below a couple of metres in the water, the sound changes so drastically due to pressure that I doubt that scuba use would be an option, even if the ergonomics of the buttons were perfect.
