LEWITT Space Replicator

Worth it for the headphone correction alone.

Useful spatial references and headphone compensation with smart safety features. Hopefully they add more spaces with future updates.

Sounds like it’s coming from "outside" my headphones!

That annoying "inside-your-head" feeling is gone. Now I can mix like there are actual speakers right in front of me. It’s not 100% perfect, but it’s a total game-changer.

Listening environment simulation

There are a few other brands making that sort of utility software but what I like in this one is the calibration of my headphones which then may be saved as different profiles. Then it become very interesting to switch headphones and simulated spaces to appreciate different aspects of the mix behavior.
