78mm Foam Earpads
78mm Foam Earpads for Headphones and Headsets
1. Determine the average diameter of the front of the earpiece. You will need to remove the foam from your earpiece to make accurate measurements.
2. If your headphone or headset is oval shaped, then you will have to measure the earpiece width and height. Once you have added the width and height, divide by two to get the average diameter.
3. These foam earpads will fit onto headphone earpieces that are between 58 to 70mm or 2 9/32 to 2 13/16 inches in diameter.
