New York, NY (September 23, 2016)—Sennheiser has introduced its new 27 series broadcast headsets, featuring a closed, circumaural headset.
The new line comprises the HME 27 with electret microphone, HMD 27 with dynamic microphone and the HMDC 27, which is additionally fitted with NoiseGard active noise reduction.
All headsets in the 27 series comply with the EC directive on noise in the workplace, and feature a fully modular design that is compatible with its sister line, the 26 series. They are fitted with a switchable ActiveGard function that protects the commentator against noise bursts. ActiveGard detects noise peaks above 110 dB, and immediately compresses the signal to 110 dB.
The 27 series headsets are fitted with high-quality microphones designed to minimize the pick-up of noise in loud environments: The HME 27 has a pre-polarized condenser microphone with cardioid pick-up pattern, frequency response: 40 Hz to 20 kHz, while the HMD 27 and HMDC 27 possess a hyper-cardioid boom microphone with a frequency response of 40 Hz to 18 kHz.
The headphones have a frequency response of 8 to 18,000 Hz and a THD below 0.1 % (measured at 1 kHz, 100 dB SPL). They are fitted with a special cable, which has a small number of coils near the earcup that acoustically decouple the headphones from handling noise that would otherwise be transmitted through the cable.
