Jabra Speak2 40 vs Jabra Speak2 75 Comparison

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.

Four beamforming mics with a rated 2.5 m pickup cover a room of up to about 4.5 x 4.5 m. That's the same room rating as the cheaper Speak2 55, so the 75's advantage is slightly longer reach and super-wideband audio that keeps consonants crisp when the meeting app supports it.

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.

The 65 mm full-range driver is the largest in the Speak2 family, where the 55 and 40 use 50 mm drivers, and Jabra rates peak output at 88 dB at half a metre. Full duplex lets both ends talk at once without the speaker ducking the mics, so a call feels like a conversation rather than a walkie-talkie exchange.

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.

You get three signal paths. The built-in USB-C cable, with an attached USB-A adapter, goes to the laptop. Bluetooth 5.2 handles the phone, and on packs that include it, the Link 390 dongle gives a PC a stable wireless link. Two Bluetooth connections stay paired at once. That's the real gap with the Speak2 55, whose Bluetooth is meant for phones and tablets and which ships without a dongle.

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 rates the 4,700 mAh battery for up to 32 hours of talk time, with about 2.5 hours for a full charge. On paper, that covers a working week of calls without reaching for the cable. However, when I ran it myself, it lasted about 20 hours of continuous Google Meet meetings on a single full charge, with only a one-minute break each hour.

Jabra Speak2 40

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.

Jabra Speak2 75

It comes in two versions. The Microsoft Teams model adds a Teams button that lights up for a meeting you can join or a missed call. The UC model works with Zoom, Google Meet, Webex and other apps over the same USB audio path. Certifications cover Teams, Google Meet and Amazon Chime, plus Cisco, Avaya, Unify and Alcatel-Lucent systems.
