Instant buy, I get mine Friday. I've used Airpods, Beats Powerbeats Pro, Airpods Pro, Beats Studio Buds, and now Beats Fit Pro.
AirPods -> fall out of my ear instantly, even walking. Putting aftermarket "wings" on them fixed the problem but you had to take it on and off every time you removed it from the case which was unacceptable long term. Also the lack of ANC is a big problem since I use headphones extensively on airplanes every week.
Powerbeats Pro -> most secure workout headphones I have ever used (when the car runs you over on the side of the road they will stay on). sound very good if a bit heavy on the bass and because of their tight fit even though they don't have ANC you do "ok" on airplanes. on the side of the road running you won't hear that car coming though. the biggest problem? huge case, huge price, and major problems with the case not charging the headphones after a few months due to wonky fit and this is something that ends up affecting nearly everyone who has bought these over an extended period of time. No wireless charging too.
AirPods Pro -> a much better fit but STILL falls out during runs, great sound, all the cool "Apple Ecosystem" features. the ANC is *very good* and the transparency mode is like magic. The fit is the major issue for me and this became my "non-workout" headphones and then I used Powerbeats Pro for workouts. The two headphone lifestyle was not fun.
Studio Buds -> came out of left field and shocked me. first the sound is near identical to the AirPods Pro which is to say: outstanding. the fit is AMAZING for me and really stays in the ear... they do not fall out during runs although on occasion loosen a bit so I push them back in firmer. They also look so much better to me without the stems. I have been wearing these as my ONLY headphones since they launched... BUT (and there is always a BUT)... the "nice stuff" from AirPods was missing. First off ANC was only 75% as good. Still plenty good for airplanes but it was clearly noticeably not as good as the AirPods Pro. Transparency mode on these SUCK and basically give you a hint of the world outside your music but everything sounds fake and hard to understand. No way I could carry a conversation leaving these in and not nearly as safe on runs. And finally all the nice stuff from AirPods... they don't turn off when you remove them from your ear, no spatial audio, no auto switching when moving between Apple devices etc. The thing is... the small size, great fit, great sound made it still worth it... UNTIL...
Fit Pro -> these look like my loved Studio Buds but with EVERYTHING fixed. Same great fit but with the wingtips that eliminate all remaining worries about loosening or falling out? CHECK. Same great sound? Reviews say even better CHECK. Better ANC? They say it is now the equal of AirPods Pro CHECK. Better Transparency mode? Thank god, the reviews say the same as AirPods Pro again: CHECK! All the nice Apple features like auto stop, spatial audio, switching etc. CHECK! Still no wireless... can't win 'em all.
I obviously have spent way too much on earphones but finally I think my dream buds are here... AirPods Pro with a more secure, fitness focus fit while ditching the stem? Yes please. I'll check back in next week and let you know how it is going.
