Frequently Asked Questions
How do I test if my speakers are working?
Click the test buttons below to play audio through your speakers. Start with the left/right channel tests to verify both speakers are producing sound, then use the frequency sweep to check full range response.
Why can I only hear sound from one side?
First, check your audio cable connections. Then verify your system's audio balance settings aren't panned to one side. Finally, test with the left/right buttons here to identify if it's a hardware or software issue.
Is this speaker test safe for my headphones?
Yes. The test tones are played at moderate volume levels. However, we recommend starting with your volume low and gradually increasing it to a comfortable level, especially when using headphones.
