..I've had the Remington and the new "Quad4" by Walker.. My only gripe with the Remington was the location of the knobs.. When they were on my head the knobs were behind the brackets that held the muffs in place and it was difficult to adjust them w/o removing them from your head..
.. The Quad4 is easier to adjust and also has "tone" control but I still can't tell direction any better than the single mic version.. Good luck... d:^) JiNC
