Feedback on 3rd party headsets

On some 3rd party headsets you may experience a high pitched squeal or feedback at high volumes. This is most likely caused by a lack of shielding between the microphone and earpiece lines, this is a headset issue. As the the beltpack system uses an unbalanced mic amplifier you will need to choose headsets with micrphone shielding such as the Clear-Com CC-300 or CC-400.
