View RequirementsProduct Overview
Built for durability and low total cost of ownership, the Biz 2300 features a Kevlar-reinforced cord that withstands office chair wheels, sharp objects, and daily wear. The FreeSpin™ boom arm rotates 360 degrees without risk of breaking, allowing agents to position the microphone optimally on either side. PeakStop™ hearing protection technology filters out sudden loud sounds above 118dB, safeguarding users from acoustic shock.
The QD connection enables hot-swapping between devices when paired with compatible bottom cables, making it ideal for shared workstations or multi-device environments. Compatible with over 10,000 traditional desk phones and all leading contact center platforms including Cisco, Avaya, and Genesys Cloud, the Biz 2300 delivers reliable performance across any telephony infrastructure.
