This is getting a lot of favorable reviews in the home studio and mixing/mastering groups -

You can choose different studios, cars, airpods or pricey planar headphones in the software (depending on how much you pay) to do comparisons to see how your mix holds up in those different scenarios.
I'm of the mind that "you can't please everyone" when it comes to a mix but for folks that are creating commercial mixes it's important for that to translate to different delivery formats and listening end games.
Pretty neat.
