Audio Tests
Play a tone in each speaker, then sweep from 20 Hz up and listen for a gap or rattle. Talk to watch your mic level, all right in the browser.
Sound problems hide in different places. A teammate says you're silent on Discord. Footsteps come from the wrong ear in a game. One earcup is noticeably quieter than the other. The mic test watches your input level live, the speaker test sends a tone to one side at a time, and the frequency sweep runs from 20 Hz up so a dead band stands out as a gap or rattle.
A dead mic is rarely the microphone. Before you blame the hardware, the test shows you where the signal stops. If the level meter never moves, check two things first: the browser permission and which input device is selected. A bar that moves here but goes dead in Discord means that app isn't using the right input. Real hardware faults sit at the bottom of that list, not the top.
Channels trip people up the same way. If a tone meant for the left ear comes out of the right, your plugs or a setting swapped them. If one side is just quieter, check the balance slider in your operating system before you assume a blown driver, since a stray balance setting silences a perfect speaker. Run the frequency sweep from low to high and listen for a gap or a rattle. That points to the speaker driver, not your ears. Some treble loss past 15 kHz is your hearing, not the gear.

Headset Test
Test your headphones and mic on one page. Play a tone in each ear, then talk and watch the input level, so a dead side or a quiet mic is easy to place.
Mosquito Tone Test
Play the mosquito tone, the 17.4 kHz buzz behind the teen ringtone and anti-loitering device. Younger ears usually hear it, while most adults over 25 cannot.

How to Test Your Headphones (Left, Right, Balance)
One earcup sounds quiet, or a game's footsteps come from the wrong side. Test your headphones' left and right channels and balance in the browser, then fix it.

Does the Water Eject Sound Actually Work?
Your phone got wet and the speaker sounds muffled. Here's what the water eject sound really does, when a low tone clears the grille, and when it can't.

How to Test Your Microphone Online
Run a live microphone test in your browser. See your input level, spot clipping or silence, check which device is active, and fix a mic that shows no signal.
FAQ
- How do I test my headphones and mic together?
- Use the headset test. You hear a tone in each ear, then talk while a level bar tracks your voice. A dead earcup or a quiet mic turns up in one pass. Test your headphones and mic together
- How do I test my microphone in the browser?
- Allow microphone access when the browser asks, then talk. If the level bar moves with your voice, the mic works. Nothing is sent to a server. Open the microphone test
- My mic shows no signal. Is it broken?
- Usually not. A denied browser permission is the first thing to clear: find it in site settings and reset to allow. Then confirm the right input is selected, and check that your OS hasn't blocked microphone access system-wide. Actual hardware failure is rare.
- Why does the sound come from the wrong ear?
- Your left and right channels are swapped. It's almost always reversed plugs or a flipped setting, not a fault. Run the left and right test to confirm which side is playing, then fix the connection or the channel setting. Test your speakers
- One side is quieter than the other. What's wrong?
- Check the balance slider in your operating system first. A balance pushed off center makes a perfect speaker sound weak or silent, and it's the most common cause of a lopsided pair. If balance is centered and one side is still faint, sweep that channel with the tone generator to find where it drops. Open the tone generator
- What does the input level meter tell me?
- It shows how hot your mic signal is. A bar that barely moves means the gain is too low or the wrong input is selected. If it slams to the top, you're clipping. Lower the input gain in your OS, or move the mic a few inches back. You want it resting in the middle when you talk normally.
- Can I test headphones and a phone this way?
- Yes. Plug in headphones or earbuds and run the left/right test first. A swapped or dead side shows up in under a minute, which beats discovering it mid-match. Check the left and right sides
