AKG Acoustics HSD 200 SR/oc Headphones User Manual


 
HSD 200 SR/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.
