The HRF-1 and HRF-2 are medium weight, noise reduction headsets with dynamic flip-up-to-mute microphones. These headsets have a noise reduction rating of 21dB and are suitable for use in moderately noisy environments. The unique design of the boom microphone allows it to be used on either side of the head, based on user preference, while also offering the convenience of flip-up-to-mute technology.

All models feature a unique, soft covered headband design that distributes ear cushion pressure evenly over the entire ear with no pressure points, unlike conventional designs, which apply more pressure on the bottom of the ear than on the top. An added advantage of this design is the headset folds into an extremely compact shape.

Features

• Flip-up to mute microphone feature.
• Comfortable foam-filled, covered headband pad and soft ear cushions. The headband pad evenly distributes the headset weight, with no pressure points, for maximum wearing comfort.
• Adjustable ear cup pressure.
• The dynamic boom arm features a sealed ball-and-socket joint and a flexible boom for precise microphone placement on any head size. The boom can be worn on either side of the head.
• The microphone cordage is protected inside the boom arm. Shielded wire throughout the headset protects against RFI and EMI. Strain-reliefs on all cords provide maximum durability.
