We offer a 7 day trial to first-time users, but once that has expired, you must upgrade to FxSound Premium to continue improving your system's audio quality.
Once you've purchased FxSound Premium, you will get an email with a serial number. Once you enter that serial number into FxSound Enhancer, you will unlock the fully optimized listening experience! Click here for more help.
You likely need to enter your serial number that you received in an email when you purchased FxSound Premium. See more instructions here.
No problem! Just follow the instructions here
and we will resend you your serial number.
For the FxSound listening experience on mobile, check out our DFX music player for Android!
