In my experience, Apple's offerings are only marginally better than the average, and are still vastly outperformed by something external.

You don't need to spend a lot, but it really comes down to a couple things:

* External, dedicated DAC

* The software doing playback has exclusive control over the device (no Windows/Apple/Android audio mixers messing it up)

* Set it for bit-perfect playback (this will disable any mixers available in the application)

* [If possible] Play a lossless copy of the audio or use a streaming service that offers that option (space is cheap in 2023)

Bam. Those steps will be night-and-day over anything integrated, it's not even close.
