Exactly. Look at something like the Sony XM5s that have a defective design that breaks in a light wind. There a class action against them for the crap they pulled and refusal to warranty. Not that I’m bitter at them or anything.
Meanwhile I had Sennheisers and they could take an absolute beating and still work fine. While also being plastic and cheap looking in comparison to other brands in the same price packet.
I gave them to a friend who "quick-fixed" them with a screw at the pivot point, but they lost all their flexibility after that. He didn't mind because he was using them solely for drumming, but I couldn't use them anymore.
That being said, I have had some nasty experiences with Sennheiser's IEMs as well. Had to send 2 of them in warranty within a year, products that were in the 300-600 euro range back around 2010!
