MICROPHONE

PROFESSIONAL HEADPHONE WITH

The lightweight headsets in the HMD 26 series,
with their closed supar-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 noise attenuation.
With all versions in this series, ActiveGard protects
the user from extreme volume peaks. The dynamic
microphone with a hyper-cardiod pattern features
excellent acoustic performance, with linear frequency
response over a broad frequency range up to 16 kHz.
The flexible gooseneck microphone can be used on
either the left or right side and it mutes in an upright
position. Another important feature it is even less
sensitive against structure-born sound.
