Counter Experience -
I've used my Etymotic ER4P for 7-8 years thus far wearing them for 4 - 8 hours a day, every day.
No running just gym work, studying, commuting (bus, train, plane). They've protected my hearing incredibly well.
I replace the silicone covers regularly and filters whenever they get dirty (once every year to 2 years since I clean my ears once a day).
I put them in the pouch they were provided with otherwise let them lay out uncoiled at home.
My Beyerdynamic DT880s (read as big headphones) are still my primary headphone, 7 years running at home.
I also bough a pair of Hifiman HE400i over the Christmas break because they are great and were selling for half their normal price on Amazon (plus I wanted some planar magnetic headphones).
I will probably get some Audio Technica A1000z for work as when I have canal phones in and the development team breaks out into discussion or I need to talk to a tester, it can be a bit annoying for both parties while I take time removing them. Plus my 2 head phones at home are both open back.
When I used speakers they would be too loud for the neighbours (I was living in an apartment at the time). So I switched to headphones and canalphones for personal use as I seem to be the exception to the rule in that I don't destroy my audio gear .
