OK ... I just went out and checked my headphones
that are in the car. They are Sony (that much I knew)
MDR-7506's ... I use them on the weekends when
I'm a disk jockey on the radio at
http://nj1015.com
They sound good, and are pretty rugged, I've been taking
them on and off and tossing them on the console about
60 times a weekend for 5 years or so.
As far as isolation, it's hard to say - when I turn the
mike on, the speakers go off, and the music is loud.
Bottom line - I like 'em.
BUT - in my office during the week, I have a nice chrome
ST-35 into Klipsch speakers, and it drowns out the
sound of about 20 computer fans ! Yellow_Light_Colorz_PDT_16
