The Jabra Speak2 75 MS with Link 390C delivers the full Speak2 75 MS performance — super-wideband audio up to 16,000 Hz, four beamforming MEMS microphones with 72 dB SNR, 88 dBspl speaker output, and 32-hour wireless battery — with the Link 390C MS USB-C adapter as the included Bluetooth dongle. This is the correct variant for organisations whose laptop fleet has transitioned to USB-C only ports.
The Teams-certified USB-C dongle provides the same stable, dedicated Bluetooth connection as the USB-A variant without requiring a USB-A to USB-C adapter. Bidirectional Voice Level Normalisation, reverberation reduction, Microphone Quality Indicator, and native Teams button are identical across both Link 390 variants.
For Australian organisations deploying Teams at scale on current-generation hardware, the Speak2 75 MS with Link 390C provides the highest portable speakerphone performance available on Teams with the correct connector for USB-C laptop fleets.

Full duplex for natural conversation
True full duplex allows all participants to speak and be heard simultaneously — no audio interruption, no turn-taking, no cutouts during fast-paced discussions.
4 beamforming mics with 72 dB SNR
Beamforming MEMS microphones with 72 dB signal-to-noise ratio provide precise directional audio pickup at up to 2.5m, with consistent performance across the full coverage radius.
Microphone Quality Indicator
The LED Microphone Quality Indicator provides real-time pickup level feedback so participants can verify their positioning relative to the device before the call begins.
Teams-certified USB-C Bluetooth dongle
The Link 390C MS is Teams-certified and provides a dedicated USB-C Bluetooth connection that does not depend on the laptop’s built-in Bluetooth — stable and consistent in high-density wireless environments.
Built for daily professional use
IP64 rating and reverberation reduction for hard-surface rooms make the Speak2 75 MS suitable for frequent transport, shared meeting spaces, and acoustically challenging environments.
32-hour wireless battery life
Thirty-two hours of wireless operation eliminates mid-day recharging even during the heaviest meeting schedules — covering extended travel and back-to-back conference days.
Enterprise fleet management ready
Jabra Direct and Xpress compatibility allows IT teams to manage firmware and settings across multiple Speak2 75 MS units simultaneously — relevant for large-scale deployments across multiple office sites.
