Really good
Made my cheap headphones better than before. Thanks to the developer❤️
Great idea
High end speaker companies DO recommend a break in period for speakers. I may try this with a new set of JBL's. Thank you for making this app
Best Burn In App in appstore
It's the best burn in app in appstore and doesn't have that idiotic low frequency white noise.
Screen is required to be on!
Not sure why I found another app that doesn't need to drain the battery faster and works like a music app, in the background.
No difference
I saw no difference in my headphones performance .Is there anything I could've done wrong?
