Poly MDA100 QD Audio Switch | 10ft Cable – 8A7E1AA

Product Overview

The Poly MDA100 QD (8A7E1AA) is an intuitive audio switch that enables seamless transition from desk phones to softphones and unified communications without investing in new headsets. Customer service representatives can effortlessly manage audio from different sources—desk phone and PC—using a single Poly Quick Disconnect (QD) headset.

Featuring an easy-to-access mute button with visual status indicator and a 10-foot coil cable, the MDA100 QD allows users to move freely during conversations while the non-slip base keeps the switch securely in place. Compatible with PCs, Macs, and all major desk phones and softphones from Microsoft, Avaya, Cisco, and others.

Who Should Use This Product?

Contact Center Agents

Ideal for customer service representatives transitioning from desk phones to softphones who need to manage audio from multiple sources with a single headset.

Hybrid Phone Users

Perfect for office workers who use both traditional desk phones and PC-based unified communications applications throughout their workday.

Why Choose This Product

The Poly MDA100 QD eliminates the need to purchase new headsets when transitioning to unified communications. Customer service representatives can focus on delivering exceptional customer experiences instead of managing multiple audio devices. The intuitive design requires minimal training, while the 10-foot coil cable provides freedom of movement during calls. IT administrators can manage device inventory using Plantronics Manager Pro software subscription service for streamlined asset management.
