Audio Seal Test

A weak seal costs you bass and isolation. Two minutes, ear by ear.

Earbuds in. Speakers can't play the test tones. Quiet room. Background noise hides the bass. Pause other audio. Music or video will confuse the test. iPhone: silent switch off — Safari mutes tones in silent mode.
01 / 04 Fit your tips

Choose the tip that creates a secure seal without pressure or pain. Twist gently as you insert, until the room goes quiet.

Your left and right ears may need different sizes. That's normal.

02 / 04 Set your volume

Play the tone. Raise your volume until it's clear and comfortable — then don't touch it again.
