I don’t really feel the wingtip. I wouldn’t say it is pressing “hard,” it’s just filling up enough space to give a needed assist.

With APP, the left one stays in decently well (unless I trip while running, which has happened before), but the right one I can only get to stay in if I replace the silcone tip with a foam one. And even then, if I eat while wearing them or something, the chewing motion works the APPs out of my ears. That doesn’t happen with BFP.

For comfort— Just now I reached up to look at my BFP and was surprised to pull an APP out of my ear— I usually wear the BFPs while working but forgot the in the other room this morning. So, yeah, equal comfort for me. Just more security and longer battery life with BFP. No other differences that matter to me. I’m not much of a music listener— Zoom calls, podcasts, audio books.
