Sonic Eject is a lifestyle application available on iPhone that offers a unique combination of a frequency generator and a headphone burner function. Designed to improve the performance and sound quality of newly bought professional headphones, Sonic Eject allows users to quickly reach a stable state and reduce distortion through burn-in. The app features a built-in frequency generator with a slide adjustment for hertz values ranging from 20 to 20kHz. Additionally, it offers an automatic full-band mode that gradually increases the frequency range from 20Hz to 20kHz in a five-minute cycle.

To burn in headphones, Sonic Eject utilizes white noise and pink noise. White noise distributes the same power across all frequency bands, while pink noise gradually decreases energy from low to high frequencies. The app recommends 20 hours of white noise and 10 hours of pink noise for optimal results. By using Sonic Eject, users can achieve a more uniform sound quality in their headphones.

Please note that Sonic Eject offers a subscription plan called Sonic Pro, which includes additional features such as the ability to freely adjust the number of Hertz and use white noise and pink noise for headphone burn-in. The subscription price is $9.99 per year with a 3-day free trial. Subscription pricing may vary in different countries, and payment is charged to the user's iTunes account upon confirmation of purchase. Users can cancel the renewal by manually disabling the automatic renewal function in the iTunes/Apple ID settings at least 24 hours before the current subscription period expires. Renewal occurs within 24 hours before expiration, and the subscription cycle extends by one subscription cycle after successful deduction from the Apple iTunes account.
