I found the little ‘wings’ on the Galaxy Buds to be the perfect little addition to help lock the Buds in my ears. I’d insert the bud and give it a slight little clockwise twist, which would slide that wing just under a ridge in my ear. Of course everybody’s ear shapes are different so I might’ve just had a coincidentally good ear shape.
I’ll agree with the accidental touches though..just slightly messing with their position in my ear would usually lead to be accidentally pausing whatever I was listening to. And after using quite a few different truly wireless earbuds, I’ll have to agree about the fit of the AirPods Pro. I suffer from the least amount of ’earbud’ fatigue wearing those, with my Powerbeats Pro following right behind. That being said, I also customized the fit by doing the ‘memory foam’ hack on my AirPods Pro (there’s a thread over in that subforum outlining how it’s done) and I swapped the stock silicone tips on my Powerbeats Pro for foam versions.
