In search of acoustically transparent foam for DIY ear pad

Post by Phiz » Mon Apr 11, 2011 10:58 am

I've got a ~12 year old pair of Sennheiser HD 495 headphones that are my go to headphones for listening to music at my desk job. They are "on-ear" headphones, with a flat pad of foam that pushes against the ear. Unfortunately the foam has degraded and Sennheiser no longer stocks replacements as this model was discontinued many years ago. The way the ear pads are constructed makes it easy to replace the foam and re-use the cloth covers that go over the foam. So I am in search of some acoustically transparent foam that I can buy in a sheet and cut to match my headphones. something in the 0.25-0.5 inch thick range. I've found some stuff online, but because the applications listed are not for headphones I'm worried the foam won't be soft. Can anyone recommend a supplier that has sheets of foam that are labeled as acoustically transparent and known to be soft?

Canm't recommend a supplier, but foam isn't as muttling to audio as you may think. I've used the foam from disposable foam paint brushes as wind screens in the past for my portable digital recorder with great results! Likely won't be big enough for you, but you can use several and cover them with that cloth cover you're talking about. Best...JD!

I use automotive headliner foam from fabric stores for my mic windscreens. Though I usually peel of the cloth layer.

Scott's recommendation is also a great idea!
