Galaxy Buds3 Pro

For me, wingtips or hooks are pretty essential in the gym for the best fit otherwise they'll just fall out. Foam tips can also really make a difference but they'll quickly ruin in the gym The Soundcore X20 work really well as do any of the Bose buds with wings.  I also have had good experiences using the OnePlus 4 with Foam tips or the Galaxy Buds 3 with azla crystal tips. The majority of other buds just fall out or need readjusting often. 

There's a lot of recommendations for clip ons, but just be aware you're going to lose a lot of sound quality with them v in ears. You may also find them uncomfortable too as the part of them that sits behind your ear starts to irritate me after a while For comfort on in ears, I like the denon pearl pros and galaxy buds 3 pro (with foam tips). You could always consider something with a hook too like the Soundcore X20 which are also pretty comfortable

The buds 3 pro is a pretty weird comparison. There's a huge amount of buds with better anc than them to compare to, and Samsung aren't one of Sonys biggest rivals in the audio space 

What's bad with them? I'm pretty happy with my Buds Pro 2 and Buds Pro 3...

Can't comment on the airpods, but the Buds 3 Pro have a better mic than xm5. Sound quality is good too. For reference, I have a Pixel 8 Pro.

I haven't tried Sennheiser, so I won't comment on them. The Samsung Buds 3 Pro for 155 euros could be a good option; I would recommend them (knowing the issues they have) if you have a Samsung phone to get the most out of them. Another alternative I offer, which might be cheaper, is the Huawei FreeBuds 4 Pro. For me, it's the best in terms of versatility compared to the Samsung.

I would not recommend these, especially the momentum 4. The galaxy buds are pretty much locked to samsung phones and the momentum 4 has a horrible microphone(i have a pair and my calls sound horrible). On the note of bass, I can comment on neither, since I use my momentums with a balanced tune, they have less bloated sound.
