Treble Booster is a free Android app developed by Wait What in the Multimedia category, specifically for Music & Radio. As the name suggests, this native app allows you to adjust the treble level of your device. To get the maximum results, you should plug-in external speakers or headsets.

The app increases the high frequencies of the Android eQualizer, providing you with a better music listening experience. It comes with two main features - Treble and Volume. You can adjust the treble level and volume level of your device using this app.

However, it is important to note that listening to music too loud is harmful to your ears. The app includes a disclaimer that it will not damage your speakers and does not have viruses that can harm your phone.
