Shox Open Run Pro 2 sound level?

Currently using the regular Open Run Shox. I use them mainly in an industrial setting where I have to be able to hear certain production equipment and a radio. My shox work great but they could be a little louder. Some of the equipment we use tends to get pretty loud.

Im wondering if the Pro 2 is a worthwhile upgrade for my needs. Other than the sound quality, im happy with everything else, though I wish the battery lasted a 12 hour shift.

Thanks for your advice.
