The new Heil Pro Set Elite is the ultimate boomset designed for commercial sportscasters, podcasters and amateur radio operators using the newly designed Heil HC 6 wide response microphone element. The new technology of the Heil HC 6 is designed for full range commercial AM or FM network broadcasts or can be adjusted (with radio adjustment) for bright, articulate audio to cut through amateur radio noise and signal pileups. 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.
