Which bluetooth headphones should I choose ?

Again with that question, but I'm naturally picky and with all these new headsets on the market and the dozen hours I put into research, Im still having a hard time to choose. The XM5 seems like the best overall for a fairly honest price, which is not that big of a deal since I can buy on second-hand websites. (Still staying away from 1000+ euros headphones, as I might not know how to appreciate the sound to its full extent)

I also saw the B&W px8 in terms of real good sound, but I haven't tested anything yet.

Sound quality is my biggest criteria, followed by decent noise cancelling.

Coming from a pair of Liberty Pro 2, loved them for years, one flew away in the streets. I think a headset will be a nice upgrade for me. I listen to everything but I like bass.

Thanks for reading all that, and I hope you can help me with my choice :)
