Detailed Specifications
Jabra GSA4993-823-309 Evolve 20SE MS Mono Headset
Overview :
The Jabra GSA4993-823-309 (commercially recognized under base SKU 4993-823-309) is an entry-level, commercial-grade single-ear (monaural) corded USB headset system. Engineered for professional contact centers, busy corporate open offices, and remote enterprise deployments, this workstation asset directly addresses the operational demands of high-volume voice call handling. It eliminates the frequent driver errors, power management cycles, and signal dropping found in consumer wireless configurations by using a reliable, direct plug-and-play wired audio path.
This "Special Edition" (SE) configuration features an updated, premium soft leatherette ear cushion layout mounted on a lightweight adjustable overhead headband. This sub-assembly contours dynamically to individual users to redistribute physical contact pressure evenly, reducing operator fatigue during prolonged communication shifts. The monaural form factor keeps one ear completely open to local floor acoustics, allowing team members to maintain ambient environmental awareness while remaining locked into active telepresence sessions.
The hardware includes an inline USB-A control terminal block that gives immediate tactile access to essential call operations, such as volume adjustment, line mute pacing, and call routing controls.Certified for Microsoft Teams and optimized for legacy Skype for Business softphone frameworks, this headset natively interfaces with enterprise operating systems straight out of the box without requiring manual software configurations or IT administrative privileges. It is intended strictly for standard USB Type-A host communication terminals and should not be deployed in high-power analog ports or high-tier severe industrial environments that require thick mechanical strain-relief shielding.
