Don’t forget that there are different methods of encoding and decoding music: if the source material is of low quality, it won’t matter what subsequent equipment you use, it will still sound pants.

For 3k (USD?) you should be able to get anything you like. Think about your use case; where will you use them (home, office, travelling), will you be consuming nor creating music as well (studio ones are always wired), can wireless ones be charged and used at the same time etc..

My Beyerdynamic ones are used daily, are very comfy but require an external DAC/amp when used with a ‘phone, which is fine for me but may be totally unsuitable for you.

Have a think about how you will use them, then get some reviews.
