Key FeATureS

•  Experience full wideband audio. The entire SupraPlus 

series takes advantage of wideband VoIP technologies. 
The noise-cancelling boom features wideband receivers to 
deliver improved speech clarity and life-like fidelity –  
which helps to decrease listening errors, repeats and 
listener fatigue.

•  Excellent receive-side audio quality. A wideband frequency 

response improves listening intelligibility.

•  Comfortable, lightweight design. Adjustable headband, 

foam ear cushions create a stable, comfortable fit.

•  Bendable click-stop microphone boom. Stays in position 

for clearer voice transmission.

•  Small, light, flexible cable. Designed for lightweight 

durability, with a single-cable design for binaural models.

•  Quick call feature. Headband twists out of the way for 

convenient quick call pick up.

•  Monaural or binaural styles. Monaural lets you hear the 

conversation and what’s going on around you. Binaural 
cuts out distracting background noises.

•  Silver version has superior leatherette ear cushions.
