You don’t need lossless audio. Seriously. AAC is transparent in all the conditions you’d use these AirPods in. Lossless is a total gimmick and shame on Apple for ever enabling that 24bit nonsense.

You don’t have golden ears. You aren’t listening closely while walking around town. Noise cancellation removes some of the frequencies. Lossless would drain battery for literally no gain in quality.

Edit: as others have noted, these do feature the ability to receive lossless audio. You should disable it.
