NOTE: This article is delivered without connection cable!

Properties:

The HMD 300 PRO is a closed monitoring headset with a frequency range from 60 to 25,000 Hz and an impedance of 64 Ohms. The built-in dynamic microphone has a hypercardioid characteristic and transmits frequencies in the range from 80 to 16,000 Hz with an impedance of 300 Ohms. The HMD 300 PRO was specially developed for broadcast applications and offers reliable passive noise reduction up to a maximum of 32 dB. Soft ear and head pads ensure a pleasant wearing comfort even during prolonged use.
