Yesterday I played same content with AirPods Pro, the Fit Pro, older AirPods, other bud type, my Sony and B&W headphones. I know other beats from my daughter's. What the new Fit Pro are if anything is just more balanced than many of their products are and more like AirPods Pro as far as seal.
Where the balanced nature really stood out was putting on my wired B&Ws. Those B&W didn't have the spatial audio or punchy definition but they showed the fit pro to have good overall tone.
The Fit Pro seemed less fiddly to me after handling them differently. I pinch them from sides not touching the buttons.
Nothing's really perfect here. I've pointed out in other posts how my winter helmets (bike, ski) can activate them more easily than others but they sure stay in and sealed compared to AirPod Pro. I can hear surroundings and don't feel plugged or pressure like some buds.
If someone doesn't want to ask Siri to change volume, there's a perfect excuse to get an Apple Watch.
I found that all wired headphones that I tried out sounded better than any wireless headphones that I ever tried (including the Air Pods Max).
Of course not the cheapest of the cheap wired ones. But also not top high end headphones. I usually use good quality middle class headphones in the $/€ 150-300 price range.
So whenever I really want to sit back and actively listen to music, I always use wired headphones.
I'm using the Beats when being too lazy to fiddle with cables, or when being on the road, or in the gym, or when making phone calls.
I agree with a little practice and holding them differently, the BFPs are less fiddly to put them on. However, I'm way more afraid of dropping them than the PBs. On the positive side, thanks to the tiny size of the BFPs, you don't have a wobbly piece of something standing out from your ear like a cork from a wine bottle. And something that fits many ears better and more firmly than the Air Pods.
On changing the volume with an Apple Watch: I have one, but this doesn't work well for me. Only for Spotify, it instantly displays some controls, including one for the volume. This is not always (or not always instantly) the case with Apple Music, and I don't know why.
When making phone calls - and this is my most common use case for volume changes - it mostly does not give me the volume adjustment option at all, or if it does (usually when I was listening to Spotify before), it moves the volume slider, visibly even on the phone, but it does not react, the volume does not change. I guess this is still the Spotify volume change, and not for the phone call. Although it says 'iphone' on the Watch's screen, not Spotify. I am confused.
So, either user errors (or improper handling), or software issues, or both.
