SoundID Reference for Speakers & Headphones with Measurement Purchased used. The previous owner bought it new from Soundhouse in December 2024. The condition is good, and there are no operational issues. I have only used it twice for speaker setup. After that, it was returned to the box and stored. The license has been deactivated. The software can be downloaded from the official website. You can use it by registering the license key (written on the included card). In addition to the license key, a domestic support ID is also included. Thank you.
