Same here. I own Peltor Bullseye 1, Peltor X4A and Toennesen ear defenders. The longest I was ever able to wear any earmuffs from the Peltor series was for 2 hrs max. Usually with breaks as your head starts to feel like it's in a vice soon. This is because these earmuffs need to create protective seal around your ears → resulting in excess pressure around that area. The pads are usually quite firm. If it's cold outside, it's even worse.
I feel you can certainly give yourself some inflammation and TMJ issues, if worn often & for prolonged periods of time. Not to mention it doesn't help hyperacusis, and all these hearing protectors have some degree of occlusion effect.
What you can do:
- get the DAA Silicone Gel Replacement Ear Pads 3M edition (make sure they fit with your Peltor model - I got them for my X4A and found out I can't replace the pads with these ones)
- alternatively you could get some noise cancelling headphones (though, I don't recommend this option as some cheaper models create literally just hiss that doesn't cancel out anything, and the good quality ones work by generating a sound that's phase-inverted by 180 degrees to the unwanted noise; with this some people report ear fullness and weird sensations in their ears) note: don't rely on the 'earplugs under the ANC headphones' advice: 1. Overprotecting, 2. No evidence it actually does something to reduce the risks.
- if you want to play it on the safe side, you could get some good quality passive noise isolation headphones (e.g. the Focal Listen would be a good option - high isolation, and it even starts at lower frequencies than many others, also the cushion pads are nice and comfy)
or..
Many issues arise here, though: 1. the
occlusion effect, 2. can vibrate in a piston-like manner within the ear cannal
[1], 3. pushing back cerumen with debris (earwax buildup & blockage), 4.
cochlear suppresion via chronic ear plugging may even cause tinnitus [2] , etc.
To reduce the occlusion effect in earplug fitting depth of insertion is important, and perhaps ear plugs with membrane technology could also help (like the
ProGuard Lin-Ear PR20 musician earplugs).
I hope this helped a little.
