Headphone & Speaker Test
A headphone and speaker test verifies stereo channel balance, frequency response, and driver health using only your browser β no downloads or installs required. The human hearing range spans 20 Hz to 20 kHz, and most adults can hear up to 12β16 kHz. This free tool checks your audio equipment across all three tests: stereo channel separation, per-frequency tone testing, and a full 10-second frequency sweep from sub-bass to ultra-high.
Stereo Channel Test
Select a channel, click Play, then verify which ear hears sound. Useful for checking dead drivers or faulty wiring.
What Is a Good Frequency Range for Headphones?
Headphone frequency range is measured in Hz. Most headphones spec 20 Hzβ20 kHz, but real-world extension and flatness vary widely. Use this table to compare your hearing result against typical ranges.
| Highest Freq. Heard | Rating |
|---|---|
| β₯ 16 kHz | Exceptional |
| 12β16 kHz | Excellent |
| 8β12 kHz | Good |
| 4β8 kHz | Average |
| < 4 kHz | Below Avg |

Frequently Asked Questions
What is a good frequency range for headphones?
Most headphones are rated 20 Hzβ20 kHz, which matches the theoretical human hearing range. High-quality headphones maintain flat, even response across this range. Gaming headsets often boost bass (60β200 Hz) and treble (8β12 kHz) for dramatic effect. Audiophile headphones aim for flat response. Frequency response does not determine how loud a headphone can get β that depends on sensitivity (dB/mW).
How do I tell if my left or right headphone driver is blown?
Use the Stereo Channel Test on this page. Click 'Left' to play sound only in the left ear, then 'Right'. If you hear no sound or significantly lower volume on one side, the driver may be damaged, there may be a wiring break in the cable or connector, or the audio source port may have failed. Try a different device to rule out a source issue before concluding the headphone is defective.
What frequencies should I be able to hear?
The human hearing range is generally accepted as 20 Hz to 20 kHz, but the upper limit declines with age. Children can often hear up to 20 kHz. Most adults aged 30β40 can hear up to 15β16 kHz. Adults over 50 commonly max out around 10β12 kHz. Hearing up to 12 kHz or higher is considered excellent for adults. The frequencies most important for speech and music are 250 Hzβ8 kHz.
What causes a buzzing or rattling sound at certain frequencies?
Buzzing or rattling at specific frequencies is typically caused by a loose driver or voice coil, debris inside the headphone cup, loose screws or parts, or the driver vibrating at its resonant frequency (usually in the bass range). If the buzzing only appears at certain frequencies or volumes, it is most likely a physical resonance issue rather than an electrical fault.
How can I improve my frequency response test results?
For the most accurate results: wear headphones properly (on-ear drivers centred over your ear canals), use a quiet room to minimise background noise masking high frequencies, set volume to 60β70% to avoid output clipping, and test both ears separately. Very high frequencies (16β20 kHz) require quiet surroundings and good headphone seal to be audible.
Does headphone impedance affect audio quality?
Yes. High-impedance headphones (150β600 Ξ©) typically need a dedicated amplifier to reach full volume without distortion. Low-impedance headphones (16β64 Ξ©) work well with phones and laptops. Using a high-impedance headphone with a phone may result in low volume and thin, tinny bass β not a defect, just an impedance mismatch.
