Soundcore motion boom plus strap mounting area worn off alarmingly

I have a pair of motion boom pluses that I use in stereo mode while outdoors.
I do dance when I have them on my shoulders.
They both show signs of the strap breaching the chassis and rubber surrounding it and have exposed a hole in the cover.
I want to know if this part of the chassis being exposed causes an issue with the ip67 rating and if there is any steps I can take to prevent any further damage.
These pics are the result of only 2 half day outdoor trips
