Full Duplex Audio for Natural, Interruption-Free Meetings
The Jabra Speak 750 MS Wireless HD Conference Speakerphone (7700-309) transmits both sides of the conversation at the same time — true full duplex audio — so discussions flow naturally without clipping or talk-over. A 10 W peak speaker, omni-directional microphone with 2.3 m pickup range and Jabra DSP deliver clear wideband HD Voice for huddle rooms and flexible workspaces.
Pre-Paired Link 370 Adapter — Wireless from the Box
The included Jabra Link 370 USB adapter arrives pre-paired: plug it into a laptop and the Speak 750 connects wirelessly with up to 30 m of range. Bluetooth 4.2 with multipoint keeps two devices connected simultaneously (8 paired), covering your UC client and smartphone at once.
11-Hour Battery in a 301 g Travel-Ready Design
With up to 11 hours of talk time, approx. 3-hour USB recharge and a soft pouch included, the Speak 750 moves between meeting rooms, hot desks and home offices. In music mode the speaker plays a full 150 Hz – 20 kHz range for multimedia and playback between calls.
Link Two Units for Stereo Coverage
Pair two Speak 750 units (0.5 – 4 m apart) at the touch of the link button for full stereo, immersive audio in longer rooms — no installation required.
Certified for Microsoft Teams with Dedicated Teams Button
The Speak 750 MS (7700-309) is Certified for Microsoft Teams and carries a dedicated Teams button to join meetings, view missed calls and bring Teams to the foreground instantly.

Frequently Asked Questions — Jabra Speak 750 MS
What is the difference between the Jabra Speak 750 MS and UC variants?
Hardware and audio are identical. The MS variant (7700-309) is Certified for Microsoft Teams with a dedicated Teams button and ships with the MS Teams version of the Link 370; the UC variant (7700-409) has a Smart button (Cortana/Siri/Google Assistant) and the UC Link 370 — best for Zoom, Webex or mixed environments. See the Speak 750 UC for the other variant.
How does the Speak 750 differ from the older Speak 710?
The Speak 710 shares the 10 W speaker and form factor, but the Speak 750 adds certified full duplex audio, a wider 2.3 m microphone pickup range and, on the MS variant, full Microsoft Teams certification. The 710 has longer battery life (15 h vs 11 h) but is end-of-life.
How does the Speak 750 compare with the newer Speak2 75?
The Jabra Speak2 75 is the next generation: four beamforming noise-cancelling microphones, Bluetooth 5.1, longer battery life and Zoom/Google Meet certifications. The Speak 750 remains a proven, competitively priced choice with the same portable form factor.
Does the Speak 750 connect over USB-A or USB-C?
The Speak 750 has an integrated USB 2.0 cable with a USB-A connector (approx. 90 cm), plus the Link 370 USB-A wireless adapter. For USB-C laptops, use a standard USB-C adapter or choose the Speak2 75, which offers USB-C options.
How long does the battery last, and can it charge while in use?
Up to 11 hours of talk time per charge; a full USB recharge takes approximately 3 hours, and the unit can be used while charging over USB.
Does the Speak 750 MS come with local warranty in Singapore?
Yes. Every Speak 750 MS sold by SourceIT comes with 2 years local Singapore warranty and a GST invoice.
