问题 The World’s Best Telephone Headsets
The Olassen Wireless Telephone Headset represents a revolution in telephone headset design.
Every headset contains two embedded microphones. The first microphone picks up every nuance in your voice before transmission; the second microphone filters out unwanted background noise. The result is an enhanced signal that sounds even better than face-to-face conversation.
This revolutionary microphone technology is further enhanced by a speaker that includes base amplification, so you hear the full voice of the person on the other end of the line.
Find the nearest Olassen retail outlet at www.olassenacoustics.com, or call 1-888-845-9000.
