90mm Leatherette Ear Cushions
Replacement 90mm Sized Leatherette Headphone Cushions
Measure the size of your earpiece from edge to edge to determine the headphone diameter
The 90mm Leatherette Cushions are approximately 90mm (3 ½ inches) across the diameter of the Cushion. They will fit onto an earpiece that is smaller than 90mm, between 80mm to 88mm (3 ⅛ and 3 7/16 inches). That's why you need to measure your earpiece size.
After removing your headset earpiece, you can measure the diameter (across from edge-to-edge) or you can measure the circumference and divide that number by 3.14 to get the diameter.
Instructions on how to determine the diameter by measuring the earpiece circumference:
1. Remove the existing cushion from your headphone or headset, so you can see the part of the earpiece that your cushion will wrap around.
2. Cut a thin strip of paper and wrap it around the outer edge of your earpiece, marking the paper at the point where it wraps around and meets the other end.
3. Measure the length of that paper strip; That will be the circumference.
4. Divide the circumference by 3.14 (known as "PI"). So if the length of the strip measured 10 ¼ inches, for example you divide 10.25 by 3.14 and the result will be 3.26 inches. That is the decimal equivalent to about 3 ¼ inches; That is the diameter. Use the diameter to decide which cushion will fit onto your earpiece.
The 90mm Leatherette Cushions will fit onto an earpiece that is between 3 ⅛ inches and 3 7/16 inches in diameter (or between 80mm and 88mm if you measured using a millimeter ruler).
