Treble Test
High tones reveal a dull tweeter, a muffled headphone, or simply the upper limit of your hearing. Step through the range or sweep it.
Lower your volume before starting, especially with headphones. Nothing plays until you press a button.
5 kHz
Hearing above 15 kHz fades with age. Not hearing the top presets is normal and says nothing about the speaker.

How to use
- Keep the volume low. High tones can be piercing even at modest levels.
- Pick a preset or drag the slider, then press Play.
- Move up the range and note where the tone becomes hard to hear. Ask someone younger to listen too; the limit is often theirs, not the speaker's.
- Use Sweep to hear the range rise from 2 kHz to 20 kHz.
What this test can detect
- A tweeter or earpiece that is dull or silent at high frequencies.
- Harshness or hiss at particular frequencies.
- A rough upper limit of your own hearing.
- Audio settings such as equalizers or hearing enhancements that roll off treble.
Important
- Hearing above 15 kHz fades with age. Not hearing 17 kHz is normal for most adults and says nothing about the speaker.
- This is not a hearing test. If you have concerns about your hearing, see a professional.
- Some speakers and Bluetooth codecs cut off around 16 to 18 kHz by design.
