40mm Foam Earpads, Bag of 4 • Part No. E-20-4

  • Each Zip-lock type bag contains 4 pieces of the 40mm size headphone foam earpads
  • These black foam sponge cushions are made of open cell foam sized for headphones and headsets
  • The foam ear cushions fit a headphone earpiece that is about the size of a US half-dollar coin
  • Replace degraded foam for your own personal headphone or headset
  • Remove and peplace the foam earpad sponge cushions on headphones that are shared by many users
  • Some call-center headsets will accept the 40mm, 50mm or 60mm size earpads or cushions

Maintain Effective Hygiene Between Headphone Users

  • Re-fresh headphones to keep them sanitary so headphones can be shared and kept hygienic and safe
  • Prevent the spread of head lice, bacteria, influenza, cmmon cold, hepititis, viruses
  • Fresh Earpads will limit users from sharing hair, body fluids and skin cells that find their way into the foam earpad material
  • Used by many call centers, schools and corporations to reduce employee absenteeism due to influenza and the common cold
  • Maintain good health and hygiene through the use of clean fresh sponge foam earpad cushions

Three methods to measure your earpiece (following removal of the earpad)

  1. Circular earpieces - You can measure the diameter going across the earpiece from edge to edge
  2. Oval earpieces - You can measure across the earpiece and then from top-to-bottom of the edges; add those values together and then divide by 2 to get the average
  3. Oval or Odd Shape earpieces - Use a string, dental floss or thin strip of paper to measure the circumference (around the earpiece) and then divide by 3.14

Example

  • Lets say your oval earpiece circumference measures 4 4/16 inches long, so you use this formula: 4.3125 ÷ 3.14 = 1.375 inches
  • If the earpiece diameter is 1.375 inches, you can see that our 40mm foam earpads will fit because it is between 0.945 and 1.38 inches in diameter
  • This same method works for metric measurements: If the circumference is 109mm) and we divide that by 3.14 it equals 34.7mm and that is between the range of 24 and 35mm so our 40mm earpad will fit
  • The 40mm foam earpads will fit an earpiece between 5/16 and 1 3/8 in (0.945 in. to 1.38 inches) or 24 to 35mm in size

It is always best to base your measurement on the size of the headphone earpiece (not the old foam sponge)

  • The earpads will stretch around earpiece outside edges or fit into a thin groove in the outer part of the headphone earpiece
  • The earpad size table (shown in the earpad images) will help you to review the appropriate earpads for your headphones

Product Composition

The foam headphone cushions are made out of a polyurethane open-cell foam material that is flexible and will stretch around the circular and oval shaped earpieces. The foam material that we use is generally higher in quality (and made to last longer) than the foam earpads that originally came with most headphones and headsets. These hypoallergenic foam earpads are completely latex-free and come packaged in a clear plastic bag. No heavy metals were used in the production of our foam ear pads; therefore they are RoHS compliant.
