78mm Foam Earpads

78mm Size Foam Earpads for Headphones and Headsets

Measure your headphone or headset earpiece to determine the diameter - We will show you how.

The 78mm foam earpads are approximately 78mm (3 3/16 inches) across when you measure the existing foam earpads. Our measurements will be based on the size of the earpiece. All our measurements are based on the earpiece dimensions, because the size of the foam will vary.

• INCH MEASUREMENT: The 78mm Foam Earpads will fit onto an EARPIECE that is between 2 5/16 inches and 2 3/4 inches in diameter.
• METRIC MEASUREMENT: The 78mm Foam Earpads will fit onto an EARPIECE that is between 58mm and 70mm in diameter

If your earpiece is oval shaped, you can wrap a string or thin strip of paper around the outer edge of the earpiece to measure the circumference. Afterwards we will convert that to give us the diameter, so we can compare that against the known sizing.

When wrapping a string (or thin strip of paper) around the outer edge, you will want to make a mark where the end of the string comes into contact with the remaining string or paper.  Then measure the length of the string (or paper) distance from the end to your mark - That distance will be the circumference of your earpiece. After you know the circumference, divide that number by 3.14 (referred to as "PI" in mathematical terms). The circumference divided by pi equals the diameter. If the diameter is between 2 5/16 inches and 2 3/4 inches, then the 78mm Earpad should fit your headphone. If not, you will need to take a look at the table to see which earpad matches your known diameter. Click Here for a table of all the size info.  For more info on how to determine which earpad or cushion to order, click here.
