My unit makes a difference BUT you must have the software running on your device and you’ll need to update it periodically
Also, you need to plug the device in first solo, then plug your headphones in
Does very well with my Fostex headphones
Taking off one star for the problematic 3.5mm input connector. If it wasn’t so finicky then 5 stars
Vision1Update: Stopped working on 03.24.19 Suddenly none of my devices would recognize it? Worked great until... Sad it died off. Not sure what the cause was as it was physically in pristine condition and not exposed to excessive heat or moisture. good while it lasted.
