Sennheiser 502179 Product Data Sheet

Based on the closed-back,

recording studio and broadcast-

standard HD 280 PRO headphone,

the HME 280i telephone headset

has been designed especially

for communications in high-

noise environments. The electret

microphone has been optimised

for close talking distances,

rejecting ambient noise and

focusing on the frequency range

of speech. The noise isolating

earcups eliminate up to 30 dB of

ambient noise to enhance

speech intelligibility.
