Holosync’s model
Holosync’s entry level uses a prescribed listening routine with stereo headphones and a multi-month progression. It is sold as a program rather than an all-purpose streaming music subscription.
Brain.fm’s model
Brain.fm offers focus, sleep, relaxation and meditation modes across web and apps. Brain.fm explicitly says its technology is not binaural beats and describes neural modulation methods on its science pages.
Current Brain.fm pricing context
Brain.fm currently lists a monthly plan at $14.99 and a yearly plan at $99.99 on its pricing page. Those prices are time-sensitive and are included only to explain the subscription model, not as a permanent quote.
Decision framework
For a dedicated, progressive meditation routine, Holosync is the more directly aligned format. For work sessions, study or switching among focus, relaxation and sleep audio, Brain.fm’s service model is more directly aligned. Evaluate evidence and fit separately from marketing language.
