Get to know this product.

The closed, supra-aural headsets HMDC 26-II-600 are designed for broadcast applications at TV and Radio especially in very noisy environments. Therefore, the headphones are dimensioned for high maximum SPL and incorporate the NoiseGard™ technology for clearer communication and less hearing stress. Additionally, the headset is equipped with Peak Level-Protection which protects the user from volume peaks above 110 dB. 

The HMDC 26-II-600 is lightweight, provides extra soft ear cushions and headband paddings for outstanding wearing comfort even during long production days. 
The dynamic microphone with hyper-cardioid pattern features brilliant acoustic performance, a reliable suppression of surrounding noise and has a shock mounted capsule for absorbing structure born noise. The short flexible part of the boom guarantees right positioning of microphone.
Following the modular concept cable, ear cushions and paddings can be replaced easily.
