View RequirementsProduct Overview
Built with total cost of ownership in mind, the Biz 2300 features a Kevlar-reinforced cord that withstands the rigors of daily contact center use—protected against office chair wheels, sharp objects, and constant handling. The 360° FreeSpin boom arm rotates freely without risk of breaking, allowing agents to position the microphone optimally on either side. At just 68 grams, the lightweight construction with foam ear cushions delivers all-day wearing comfort.
The Quick Disconnect (QD) connector provides flexibility to connect to desk phones via compatible bottom cables (sold separately), enabling hot-swapping between workstations. PeakStop hearing protection technology automatically filters sounds above 118dB, safeguarding agents during extended call sessions. Compatible with over 10,000 traditional desk phones and all major UC platforms when paired with appropriate adapters.
