I can't remember ever dropping my headphones, or any of my cameras either. My iPhone fell out of my shirt pocket into the toilet once which was a near catastrophe, but I blamed that on me not being careful enough. I didn't blame it on the iPhone case.
I have a canvas tote bag that holds all of my portable audio stuff... It has my cans, my bluetooth speakers, battery packs, AirPods Pro, cables, chargers, memory cards full of music, Car Alexa, etc. I've got everything in there in canvas bags to keep it all organized. No big bulky cases. I take care of the bag. I don't throw it on the ground or swing it into chair legs or anything like that. It seems to protect everything just fine.
I bought a round case like the photo at Amazon. It was cheap. I haven't used it yet though. I usually just put on the bra and put the APMs in the canvas bag. It's funny. I see all the reviews complaining about the bra, but I thought back and whenever I buy something like an Oculus or a camera or something like that, I go out and buy one of those semi hard shell cases with the zipper, but I never end up using them. They just take up too much space like that, and I don't like having to unzip to extricate them from the case every time. But I'm using the bra. Go figure. Maybe there is a concept behind the simpler case.
