HSD 200SR/oc

Communication Headset

Description

The HSD 200 SR is a combination stereo headset and close-talking dynamic microphone intended for modern hands-free operation in a communications environment. The microphone response has been tailored with a gentle roll-off below 200 Hz and a broad peak centered at 3 kHz to increase speech intelligibility. The semi-open, supra-aural headphone fittings provide a comfortable fit, while the semi- open design enables the user to directly hear sounds and speech originating near by. Attention has been paid in the design to avoid leakage from the headphones directly into the microphone. In typical AKG fashion, the cable which contains both headphone and microphone leads exits only from one side of the assembly, which promotes comfortable and convenient wearing of the HSD 200 SR.
