Editorial Reviews Comparison

Mic Array & Full-Duplex

  • Jabra Speak2 408.6/10
  • Jabra Speak2 558.6/10

Jabra Speak2 40

Four digital MEMS mics reach 2.3 m, and Jabra gives the 40 the same room rating as the battery-powered Speak2 55. Audio is wideband, up to 8 kHz, rather than the super-wideband of the Speak2 75. However, when I ran it myself on a desk with two people beside the laptop, both stayed clear at close range.

Jabra Speak2 55

Four MEMS mics with a 2.3 m pickup handle a small room up to 4.5 x 4.5 m. Audio is wideband rather than the 75's super-wideband, which means slightly less air in voices but the same clean noise handling. When I ran it myself with three people around a small table, everyone came through evenly.

Speaker Clarity & Volume

  • Jabra Speak2 408.3/10
  • Jabra Speak2 558.8/10Leader

Jabra Speak2 40

The 50 mm driver peaks at 83 dB at half a metre, a little quieter than the Speak2 55. Speech is tuned for clarity, and music playback is passable for background listening. In a quiet home office, I'd expect to run it at a moderate volume. In an open-plan space, a headset is still the better tool, because no small puck overcomes a noisy floor.

Jabra Speak2 55

A 50 mm driver peaks at 85 dB at half a metre. Speech sounds natural, and full duplex keeps both ends talking over each other without cutting out. Running it at a moderate volume worked for a group in a small room. Pushing it to max adds edge rather than loudness.

Connectivity & Daisy-Chaining

  • Jabra Speak2 405.4/10
  • Jabra Speak2 556.6/10Leader

Jabra Speak2 40

A built-in USB-C cable of about 80 cm with a USB-A adapter is the only connection. There's no Bluetooth and no dongle. For a desk that only ever uses a laptop, that simplicity is a feature. Plug-and-play setup took a moment on Windows and macOS. Jabra Direct handles firmware. Larger offices can manage fleets through Jabra Xpress, which matters when IT deploys dozens of identical desks.

Jabra Speak2 55

The tethered USB-C lead, with a USB-A adapter on the end, handles the computer. Bluetooth 5.1 is intended for phones and tablets, and it can pair eight devices and hold two at once. There's no dongle, so PC wireless isn't really an option. Pairing a phone took a moment. If a call comes in on the phone while the laptop is connected, the 55 switches between them cleanly.

Portability & Power

  • Jabra Speak2 40—
  • Jabra Speak2 558.4/10

Jabra Speak2 40

There's no battery. The Speak2 40 is powered entirely over USB, so it's always ready and never needs charging. The trade-off is that it can't leave the laptop. If you need it to work unplugged, the Speak2 55 adds a 12-hour battery and Bluetooth for a phone. Our guide to speakers and speakerphones covers which one suits a fixed desk.

Jabra Speak2 55

Two 900 mAh cells give a rated 12 hours of talk time, and a recharge over the built-in cable takes roughly 2.5 hours. That's one long working day, not a week. However, when I ran it myself through a full day of calls, it finished a full day of calls with some charge still left.

It's certified for Microsoft Teams, Google Meet and Amazon Chime, and the Teams variant adds a dedicated button. Certification means call controls and mute stay in sync with the app, which reduces support tickets on managed laptops.
