Nothing new here then. Back when I used to DJ some 20+ years ago, people would complain back then that Sony headphones would constantly break on them.
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.
Yeah, I had a pair of MDR-V700 back in the day, and they broke in about 2-3 years max, without any abuse, just randomly.
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!
