Pro tip is a spl meter. Mine is set to 70 SPL measured at my desk. It's a nice way to reference. If the levels differ between the reference and your track you can perceive one as more bass and shiny (Fletcher Munson Curve). So, a SPL meter medicates that. You can also loudness match after you set your playback volume via LUFS if you like to really nerd out and have a fair reference.
