The Pro Set Elite offers dual side, highly efficient speakers mounted in acoustically tuned chambers which produce high rejection of outside noise.
The exclusive Heil Phase Reversal feature allows the user to move the signal acoustically, which creates a spatial widening of the sound field that makes it easier to 'see' a signal inside a pileup while removing listener fatigue during prolonged use.
The headphone's speakers fold up for easy transportation and storage.
The field-replaceable cushioned ear pads also come with removable cotton covers that can be easily removed for washing. The 6' coiled cable terminates in a 1/8" mono plug for the microphone, and a stereo 1/8" plug for headphone speaker connection.
A 1/8" to 1/4" adapter is also supplied.
The PRO SET ELITE works with all Heil AD-1 adapter cables, which mate with just about every type of amateur radio transceiver.
