If your speakers or headphones do not reproduce sufficient sound volume for comfortable listening to music or watching video content - use our extension as a speaker amplifier, setting the volume level to more than 600%. Use the sound booster of it on your favorite sites. Just adjust the sound in the current web tab using the slider. ☑️ Sound level over 600% ☑️ Simple and intuitive design, convenient operation ☑️ Automatically shuts off in normal mode ☑️ Switch to any tab that plays audio with one click ☑️ Smoothly increase the volume using the slider 🖥 Full screen Chrome doesn’t allow you to switch to full screen mode when using any extension that processes sound, so you can always see a rectangular icon in the tab bar (to know that the audio is being processed). It is impossible to get around this, after all, it is a good thing that protects you. However, you can improve the situation a bit by pressing F11 (on Windows) or Ctr + Cmd + F (on Mac). 💬 We are always happy for your suggestions!
