Sennheiser HMDC 26 Dimensions

HMDC 26
The lightweight headsets in the HMDC 26 series, with
their closed supra-aural design, have been developed for
professional broadcast applications. The headphones are
dimensioned for particularly high sound pressure levels.
The headsets are exceptionally comfortable to wear
while providing a high degree of passive noise
attenuation. In contrast to the HMD 26, the HMDC 26
is equipped with active noise compensation,
Sennheiser’s NoiseGard™.
This makes the headset particularly suited for use in
extremely noisy environments.
The dynamic microphone with a hyper-cardioid pattern
features excellent acoustic performance, with linear fre-
quency response over a broad frequency range up to 16
kHz. Another important feature it is even less sensitive
against structure-born sound. The flexible gooseneck
microphone can be used on either the left or right side.
Both allow users to make exact adjustments to their
individual requirements.
