      Comments about Countryman Isomax Headset (Black):

      We have had an older version of this headset for a long time. So when looking for a new one we wanted to go with a Countryman again. Straight out of the box this sounded just as we expected. If you are in need of a pro headset for a singer type...they are bulletproof.
