DA55 and DA60: Echo Suppression

The DA55 and DA60 USB to headset adapters come with echo suppression technology. When delays are excessive on VoIP transmissions, the side tones become echo, which is distracting for the people on both ends of the call.  Excessive delays are more common in VoIP systems than with standard telephony, meaning that echo suppression is a critical component in improving VoIP call quality.
