HD600 are hard to drive, they should sound notificably better on a dedicated headphone amp versus a ThinkPad. Many years ago I did this comparison and the difference was very significant, I've never used a stock headphone jack since.

This can vary across onboard sound devices, like for my HD600 headphones, I ended up doing a quick check across various headphones jacks and got very mixed results:

- 2 of my 3 monitors audio outputs: Good

- Desktop rear audio port: Good

- MacBook Pro audio port: Good

- Third (different model) monitor: Usable

- Desktop front audio port: Usable

- Framework laptop: Usable

- Nintendo Switch: Poor

- Surface Go tablet: Poor
