Ok had a pair of hd-60 David Clarkes for ten years . Before my present job I decided to purchse something new, so I got a pair of PELTOR STRATOS with anr 9v bat in the ear cup, very light, and compact when stowing etc. Except the anr circuitry is hopeless and supplies no nr at all. DONT BUY A PELTOR! I am going to get my beloved HD-60S back.
