The connection type has nothing to do with it though. Modern bluetooth is basically transparent with 256kbps AAC, like you'd have to be an omega-expert listening in a silent room to identify it vs lossless. Certainly the difference you're noticing is just the headphone quality.
Honestly for me the Airpods 4 with ANC are one of the greatest feats of audio engineering ever. For such a tiny form factor they reproduce really great sound, big soundstage, AND they have good ANC without needing a closed earbud seal. They also have internal mics that listen to the response of your ear to adjust the sound profile, which you can hear happen in real time after bumping the earbuds. Obviously you can get better sound if you make different tradeoffs and wear over-ears, but they are absolutely cutting edge for what they are.
