Fix My Speaker — Sound Test

Choose from six locally generated sound tests: Deep Bass, Music Bass, 808 Heavy Kick, Clear Voice, High Tone, and Full Sweep. Select left, right, or both channels, set a short 10-, 20-, or 30-second session, and stop playback whenever you like. The popup uses the familiar Fix My Speaker dark-and-lime design and gives you a quick link to the full website. Test tones are generated on your device after you press Play. The extension requests no browser permissions and does not read your active tab, save your settings, or collect data. Start with your device volume low. This extension helps you test sound; it does not physically clean, diagnose, or repair speakers. Keep the popup open during playback.
