Re: Earpads Shedding

...earpads are flaking pretty badly, leaving little back bits around the home office/shack…

Took me a while to realize it was my earpads shedding, glad to read this isn’t an isolated occurrence. Now how to remedy that problem?

Re: Earpads Shedding

Here’s my solution:
Garfield Headphone Softie Earpad Covers (Black, Pair) $17.00

from B&H: https://www.bhphotovideo.com/c/product/368310-REG/Garfield_SGARHS1_Headphone_Softie_Earpad.html <https://www.bhphotovideo.com/c/product/368310-REG/Garfield_SGARHS1_Headphone_Softie_Earpad.html>

Works well…

What headphones do you have? If Heil or RadioSport, they have replacement
pads you can purchase. In my experience, once the vinyl starts to flake, you
are doomed to having them continue to make a mess even if you cover them
with a slipcover.

I went online and got packs of the cloth headphone earmuff covers for
mine. Work good, washable, stretchable, several in a pack, inexpensive.
I got a small pack and large pack. large covers the yamaha 500
headphones well. Smaller ones cover the cheaper music headphones.

Re: earpads shedding

In reply to this post by Elecraft mailing list

I recall reading that navy sparkies used ladies' falsies as nice soft,
scented pads.

Re: Earpads Shedding

In reply to this post by Elecraft mailing list

Very low cost replacement ear pads are available for most f headphones
on eBay and ... um ... amazon (although I never shop on amazon.)    If
pads your model is not specifically identified, you can usually find a
suitable replacement based on its dimensions, typically measured in
mm.   Ear pads get "flaky" and soiled over time.   If you cannot clean
them (for example, many foam or velour pads can be cleaned and
sanitized) you can replace them for (usually) less than $10.   Like
tires and window wipers on a car, ear pads get flaky and dirty and old
and ... replacement is a piece of cake at low cost.   I particularly
like the extra thick, very soft, pliable memory foam pads that cost
between $9 and $15 - which can be purchased by the mm diameter to fit
nearly any circular earphone receiver. Very luxurious.   No big deal,
this is a very routine matter these days.

Just MY take.   K8JHR

Hi,

I bought a set of these for my oldest set of CM500's and they are very
comfortable. Thanks for the suggestion.
