The acoustic sealing of a closed, circumaural headset combined with a lightweight, comfortable design – this is the hallmark of Sennheiser’s all new 27 series broadcast headsets, which were introduced at this year's IBC. The 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.

“The 27 series is our latest offering for commentators and high-quality intercom use,” said Nicole Fresen, product manager, Broadcast and Media. “Extensive field tests with broadcasters have shown that these models are outstanding in their combination of effective noise isolation with excellent comfort for the wearer.”

Bringing a new age of user comfort to commentary booths
Unlike other closed, circumaural headset models on the market, the new 27 series is lightweight and compact, and will remain comfortable over long working hours. Soft earpads have been combined with Sennheiser’s classic ‘split’ headband, which opens automatically when the headset is put on and keeps the sensitive fontanelle area of the head free from pressure. For users who prefer a conventional headband, a wide headband padding is included that converts the two-piece headband into a single piece.

Noise protection at work
All three headsets comply with the EC directive on noise in the workplace, as they are fitted with a switchable ActiveGard™ function that protects the commentator against noise bursts. ActiveGard reliably detects noise peaks above 110 dB, and immediately compresses the signal to 110 dB, ensuring that any transmitted information remains fully comprehensible.

Quality audio transmission and playback
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-polarised 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 wide 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.

A NoiseGard™ model for loud environments
The HMDC 27 with switchable NoiseGard™ active noise reduction is an ideal choice for commentator and camera work in loud environments. NoiseGard™ does not only increase intelligibility, it also protects the user’s hearing and avoids noise-induced stress and fatigue.

For ease of operation, the active noise reduction does not require batteries but is powered via the P48 power supply from the broadcast desk. “This is the only commercially available broadcast headset with ANR that has such convenient powering,” adds Fresen.

Compatibility and sound signature
The design of the headsets is fully modular and compatible with the supra-aural 26 series, so that any existing cables can additionally be used with the new sister models. As the microphone booms are also compatible, broadcasters can ensure a consistent sound profile where both the 26 and 27 series are used.

The new HME 27, HMD 27 and HMDC 27 will become available later this month.
