The Jabra Speak2 55 UC extends the Speak2 40 with Bluetooth connectivity, giving users the flexibility to connect wirelessly to a smartphone or tablet alongside a USB-connected laptop. Four Digital MEMS microphones and a 50mm speaker cover rooms up to 4.5m × 4.5m with 85 dBspl peak output — an improvement on the Speak2 40.
Full duplex audio, Acoustic Echo Cancellation, and Voice Level Normalisation deliver consistent call quality across varying room types and participant volumes. Wideband audio extends the captured frequency range beyond standard narrowband for more natural-sounding speech.
Microsoft Teams certified and compatible with Google Meet, Zoom, and major UC platforms, the Speak2 55 UC suits professionals who split their working time across office and home environments and need a single device that works reliably across both setups without reconfiguration.
Instant speakerphone wherever you work
The Speak2 55 connects via USB or Bluetooth and is operational immediately — suited to office desks, home setups, and temporary working locations without any configuration.
- Bluetooth + USB-A + USB-C — connects wirelessly to a mobile device while simultaneously connected via USB to a laptop.
- 4 Digital MEMS microphones — omnidirectional pickup up to 2.3m, covering rooms up to 4.5m × 4.5m.
- 85 dBspl peak output — louder than the Speak2 40, suited to slightly larger spaces or noisier environments.
- Full duplex audio — natural two-way conversation without audio cutting or artificial turn-taking.
- Wideband audio — captures more of the voice frequency range for clearer, more natural-sounding calls.
- Microsoft Teams certified — tested and optimised for Teams meetings straight out of the box.
Full duplex for uninterrupted conversation
Full duplex technology means both sides of the call can speak simultaneously without the audio cutting out — conversations flow naturally without the stop-start behaviour of half-duplex devices.
MEMS microphones filter background noise
Four Digital MEMS microphones with noise reduction filtering isolate speech from ambient sounds, ensuring the far end hears the intended audio clearly regardless of the local environment.
Big sound for the room
The 50mm speaker with 85 dBspl peak output delivers clear, room-filling audio — sufficient for small meeting rooms and open-plan spaces without requiring a separate speaker system.
Compatible with all major UC platforms
The Speak2 55 UC is certified for Microsoft Teams and compatible with Zoom, Google Meet, and other major platforms — no configuration required to switch between meeting applications.
Familiar design, improved acoustics
The Speak2 range retains the compact puck form factor familiar from the original Speak Series, with a fabric speaker cover that improves acoustic performance over the previous hard-shell design.
Portable enough for daily transport
At under 200g, the Speak2 55 fits in a laptop bag and is carried between locations without a dedicated case, suitable for professionals who split time between office and home environments.
USB-A and USB-C supported
Both USB-A and USB-C connections are available on the same device, eliminating the need for adapters when moving between older and newer laptop models.
Ready for USB-C workflows
With native USB-C support alongside USB-A, the Speak2 55 is compatible with current-generation laptops that have moved to USB-C only, without requiring a hub or dongle.
