I was playing bass at a session yesterday and ended up with a pair of Sharpe
660-D headphones. These are an archaic set from the seventies, but I loved
them. I've never heard the Bass better through headphones.

I think part of the trick was the huge solid earcup, and they clamped on
my head like a pair of lampreys, so isolation was excellent. Perhaps some
folks would find them uncomfortable, but they worked for me.

Would anyone know of these headphones, and/or possibly recommend something
current that would be similar?

The kicker was that the studio owner told me they were $5 at a yard sale.
