[Elecraft] Isolation headphones

[dw]

I think I've tried everything.
I have the David Clark and another Sound studio set of over-the-ear
headphones that are rated at around 24db isolation.  Both of them are
not sufficient for my shack environment when its noisy.

I think the best I have are custom molded inner-ear units that I had
made up at a motorcycle rally.
There was a gal there custom making them for people.
These are the kind you see people use on stage standing in front of
killowatt guitar amps.  ;~]

To get the same but on the cheep, I got a pair of el-cheep-0 KOSS inner
ear units with the black rubber foam.  Take the foam off and take a pair
of sleep ear-plugs ( the kind that you shrink up and they expand in your
ear).  Take a hot needle and boar a hole through the center.  Super glue
them onto the ear-phones.

Best isolation I've ever had and cost is less than $25 bucks!
Go figure :)
