I once found this damage on my headphones on both sides, it is unclear what caused it, and the continued uses causes the damage to expand. I’m seriously concerned as I’m sensitive to such issues. The headphones are less than a year old.
Solution: Glasses have been the problem, read one of the many replies below for more details.


I wear glasses, using the same headphones since 5 years and they never caused any damage. All the recommendations saying “just get new ones” are pure consumerism and what got us into this state of filling up our oceans with rubbish. Buy quality headphones not cheap crap and you won’t have this issue.
I appreciate your comment, but I most correct you on the “cheap crap” part. I wouldn’t consider the Accentum Sennheiser Plus Wireless “cheap crap”, but rather a bad design choice on the manufactures end.
These being senns, I don’t think they fall into the “cheap crap” category.
Also, replacing the foam is far better than replacing the whole unit. If you have a recommendation for foam pad replacements that will last years, that would be awesome!
Thank you for the response, and I would love to know too. /gen
Last time I had the pads on mine disintegrate, I found some replacements that were made of real leather. I haven’t had to replace them since. Some brands also make fabric pads; I’m sure they probably last longer than polyurethane, but I would expect them to wear out eventually.
I would prefer materials that weren’t sourced from animals (no judgement).
Ah yes, the famous “repair worn out pieces”, that consumerism is known for
Buying cheap crap only to replace it with another piece of cheap crap soon is consumerism, yes
you don’t seem to understand what people are saying. but good for you for trying
Buy new ear pads is consumerism, but buy another pair of headphones is good?
