Been using brain.fm which claims to do similar with their cerebrally-engineered audio. Anecdata point one can report feeling much more focused and engaged when it is playing.
Unless you're wearing an EEG device, it's probably different from what's being studied here. Audio entrainment without feedback has been known for 40+ years and hasn't shown meaningful benefits AFAIK.
It can have positives, not sure if they tested it alone
