Looking for a better sound?

Try Neutralizer and see how it's been customised to respond to your personal hearing parameters.



JAVEO has arrived at a conclusion that many music enthusiasts are often left to their own when it comes to improving their listetning experience for there are no professioanal tools or apps which would deliver the right sound to the receiver. This is becasue each person hears differently and therefore each sound should be profiled and customized to each person’s specific hearing abilities and music needs. Ands that’s why JAVEO created Neutralizer



We designed and created a highly-sesitive app that tests users’ hearing ability in key frequency ranges, adapts the system equalizer to take it into account and allows to create personalized profiles. Still available on Android in Google Play Store



Sound reproduction that uniquely matches and responds to your personal hearing parameters.

Current Limitations

Neutralizer may not work for everybody. There are mobile devices that are not compatible to our product that don't allow third party apps to control the system equalizer. We are working towards a solution to satisfy everybody, but for the time being your mileage may vary. It is, what it is.
Please don't give us bad rating because of this. We told you so.
