WHY CHOOSE THIS PRODUCT?

  • Purpose-built UC communication: The UC configuration is suited to enterprise voice and collaboration deployments rather than general-purpose consumer listening.
  • Three-microphone architecture: Digital MEMS microphones are designed specifically for professional call pickup, supporting clearer workplace conversations.
  • USB-A deployment advantage: A dedicated USB-A interface can simplify rollout across existing business PCs, thin clients and workstations that retain USB-A ports.
  • Mono productivity design: The single-ear configuration allows users to remain aware of colleagues and ambient workplace activity while communicating.
  • Fleet management support: Jabra Direct and Jabra Xpress provide useful administration options for organizations managing multiple Jabra devices.
  • Workplace awareness: The visible busylight helps communicate call status and can reduce avoidable interruptions.
  • Procurement clarity: The specific 24189-889-999 identifier distinguishes this UC Mono USB-A version from USB-C, USB-C/A, Stereo and Microsoft Teams variants.
  • Lifecycle consideration: Buyers should verify stock and successor availability because Jabra documentation identifies the original USB-A/USB-C SKUs as being replaced by USB-C/A variants.
