    • It is much easier to insert and remove the muff body clips by rotating them 90°. The plastic stud underneath is oval in shape and is indicated in green on the image.

    • Remove pad by inserting a large flathead screwdriver or butter knife just underneath the plastic backing plate of the padding and continuing all the way through to the muff shell. Then twist forcefully, and the underlying plastic should pop off. Using a finger is nearly impossible on the first attempt, but works on subsequent attempts.

    • Now it's free! But be careful to not twist or yank the cable.

    • Left side speaker and its cavity is 37mm wide and 16mm deep. There is extra space underneath the speaker, maybe for better acoustics. The rubber gasket is glued on. The right side had a similar cavity, although not as deep.

How about the headband? Is it replaceable? Or maybe the ear cup tip?

I don't know if you can find the headband as a replacement part. However, the gel ear cups are replaceable. Just look for 3M Peltor Gel Ear Cup replacements.
