Well if it makes you feel any better the new Powerbeats fit case is just slightly larger than the pro 3’s so finally now it’s more pocketable.I'll be honest, not a huge fan of the BFP. They stay in my ears well enough, but they are also uncomfortable after a couple hours. That said, my biggest grip was really the case. I've dropped them a couple times just because of the awful slick plastic texture, coupled with the awkward size that makes them not fit that great in pockets. Not sure anything here improves upon that, unless I misread.
Might make a move to try the AirPod Pro 3 going forward and just keep these in the gym bag.
