Galaxy Buds3 Pro

I got mine from Amazon from the official listing, which includes 2 years of warranty. I bought mine on this listing https://amzn.to/462kBMj

You should buy the buds 3 pro, but the OEM tips won't be good for the gym. You will need some IEM eartips, I used the azla eartips and they are awesome. I bought my galaxy buds 3 pro on Amazon and they are on sale right now, and I also bought the eartips on Amazon. I bought them from these listings Azla eartips: https://amzn.to/4lFIgI0 Buds 3 pro: https://amzn.to/4o51jNu

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 

I personally like the Galaxy Buds best here with Nothing a close second. I haven't actually tried the freebuds 4 enough to comment however 

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.
