Sennheiser HME 27 Audio headset, 64 Ω per system, circumaural, condenser microphone, cardioid, cable not included - 506899

Product Overview

The Sennheiser HME 27 is a professional broadcast-grade circumaural headset engineered for commentators and audio engineers who demand uncompromising wearing comfort during long shifts. It pairs a pre-polarized condenser microphone with cardioid directivity, delivering precise, transparent audio capture at the highest broadcast quality. The closed circumaural earcup design provides exceptional passive noise attenuation, making it equally effective in loud stadium environments, outside broadcast vans, and controlled studio settings. Note that a compatible cable — such as the CABLE II series — is sold separately and must be selected to complete the system.

Product Description

Built on Sennheiser's acclaimed HM 26 platform, the HME 27 advances the standard for broadcast headset ergonomics with its signature split two-piece headband design. Unlike conventional single-arch headbands that press directly on the fontanelle, the split headband distributes weight across the sides of the head, eliminating pressure points during marathon commentary sessions. For users who prefer a traditional feel, a wide single-piece headband pad is included in the box. The soft circumaural ear cushions form a gentle but effective seal around the ear, contributing to the headset's high passive attenuation while keeping the listener comfortable across extended work hours. Swiveling ear cups allow one-cup monitoring when talkback or environmental awareness is needed, and the microphone boom is fully repositionable from right to left side to suit individual preference. The condenser cardioid microphone captures voice with accuracy and detail, rejecting sound arriving from the rear and sides — an essential characteristic when multiple commentators work in close proximity. ActiveGard hearing protection is built in with an on/off switch, safeguarding against sudden noise peaks above 110 dB. The modular cable system gives broadcast facilities the freedom to standardize on a single cable type across multiple headsets, with the CABLE II series fully compatible. At 64 Ω system impedance, the HME 27 interfaces cleanly with professional broadcast amplifiers and intercom panels alike.

Frequently Asked Questions

Q: Is a cable included with the HME 27?

No. The HME 27 is sold without a cable. Sennheiser's CABLE II series cables are compatible and available separately — contact Creation Networks to order the correct cable for your application.

Q: What is the difference between the HME 27 and the HMD 27?

Both headsets share the same physical platform and comfort features, but the HME 27 uses a condenser cardioid microphone while the HMD 27 uses a dynamic hypercardioid microphone. The condenser capsule in the HME 27 offers higher sensitivity and a more open, detailed sound, making it well suited to controlled studio and commentary booth environments.

Q: What does the ActiveGard feature do?

ActiveGard is Sennheiser's built-in hearing protection circuit. When switched on, it limits sudden audio peaks above 110 dB SPL at the ear, protecting the user from unexpected loud signals — such as crowd noise surges or technical faults on an intercom line.

Q: Can the microphone boom be moved to either side?

Yes. The boom arm can be repositioned from the right side to the left side to accommodate personal preference or operational requirements without tools.

Q: What intercom and broadcast systems is the HME 27 compatible with?

The 64 Ω system impedance makes the HME 27 compatible with a broad range of professional broadcast amplifiers, intercom mainframes, and production consoles. Verify impedance matching with your specific system before ordering.

Q: Can the ear cushions be replaced?

Yes. The ear cushions are user-replaceable, which is important for hygiene in shared multi-operator environments such as broadcast commentary positions where headsets rotate between users.

Q: How do I convert the split headband to a single-piece headband?

The HME 27 ships with a wide headband padding insert that clips over the split two-piece headband, converting it into a traditional single-piece configuration for users who prefer that fit.

Q: Where can I purchase compatible cables for the HME 27?
