Common questions about call center headsets

How Cyber Acoustics Approaches Noise-Cancelling Call Center Headsets for Clearer Customer Conversations
The AC-304TR uses AI Environmental Noise Cancelation with dual microphones and a DSP built into the dongle. All processing happens locally on the headset, so background noise like chatter, HVAC, keyboards, and alarms is removed without the cloud latency of software noise cancelation. That keeps the agent's voice clear for the customer on every call.
What is AI Environmental Noise Cancelation?
AI Environmental Noise Cancelation uses dual microphones and AI digital signal processing to remove background noise so your voice sounds clearer on calls. It handles steady sounds like fans and office noise as well as sudden or high-pitched sounds like barking dogs, alarms, and keyboard clatter.
Is the AC-304TR suitable for call center environments?
Yes. It is built for contact center use with an AI Environmental Noise Cancelation microphone, lightweight design for 8 to 12 hours of comfortable wear, USB plug-and-play compatibility, and durable construction for daily operation.
How does a supervisor monitor or join an agent's call?
When paired with the HS-1500BT II supervisor headset, a supervisor can listen to both sides of an agent's call. Pressing the Microphone Select button switches the active mic to the supervisor so they can speak with the customer directly, then switch it back to the agent without dropping the call.
Should I run Krisp, Sanas, or softphone noise cancelation with this headset?
No. The AC-304TR already removes background noise locally. Running a second noise-cancelation algorithm on top can muffle or distort the audio, so turn off noise cancelation in your softphone or third-party software.
Do I need drivers or special software?
No. The AC-304TR uses standard USB audio drivers built into Windows, macOS, and ChromeOS. No additional software installation is required.
What applications does the headset work with?
It works with Microsoft Teams, Zoom, Google Meet, Cisco Webex, Messenger, and softphones used in contact centers. Because it uses standard USB audio, it works with most communication platforms.
How should I position the microphone for the clearest calls?
Position the microphone 1 to 2 inches from your mouth with the opening facing your mouth, not turned outward. Do not stick the boom straight out or cover the mic with your hand, which distorts the audio.
