its noted but with the use of an external source even something analog i think an external device would sound better to convert the audio

Why would it sound better?

To obtain the best "hi-fi" audio quality (i.e. higher fidelity), the best way to use the PX is via USB-C.

Use of the 3.5mm input is the least recommended use, as it is the least hifi one.

That said, the concept of "higher quality" is mostly subjective so it's even possible that you'll find a more pleasant sound while using them with 3.5mm cable
