Mic Array & Full-Duplex
- Anker PowerConf S5009.2/10Leader
- Jabra Speak2 558.6/10
Anker PowerConf S500
Four mics with a 5 m rated pickup and 32 kHz ultra-HD voice sampling put the S500 in a different class from Anker's own S3. Anker rates it for 12 people, or 20 when two units are linked. When I ran it myself in a ten-seat room, people at the far end stayed clear, which is the longest reach I'd expect from any puck here.
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
- Anker PowerConf S5009.3/10Leader
- Jabra Speak2 558.8/10
Anker PowerConf S500
A 1.75-inch full-range driver pushes 10 W, with a range from 80 Hz to 20 kHz. That's more than three times the S3's output, and there's a music mode for playback between calls. At a moderate volume, it filled a medium room without the harsh edge small pucks get when pushed.
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
- Anker PowerConf S5009.8/10Leader
- Jabra Speak2 556.6/10
Anker PowerConf S500
The S500 connects by USB-C, over Bluetooth 5.4, or through the included dongle. Pairing two units wirelessly extends coverage for larger rooms. That combination is rare at this price. Linking a second S500 took a moment with both units side by side. Once linked, place them at either end of the table rather than bunched in the middle.
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
- Anker PowerConf S5008.0/10
- Jabra Speak2 558.4/10Leader
Anker PowerConf S500
Anker rates the 6,000 mAh battery at 13 hours of talk time and 16 hours of playback, with a slow 4-hour charge. That's fine for a meeting room where it lives near a socket, but less suited to a full day of travel. In my own back-to-back calls, I'd plan on a working day's runtime at room-filling volume before it needs the cable.
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.
Call Controls & Certifications
- Anker PowerConf S5007.5/10
- Jabra Speak2 559.8/10Leader
Anker PowerConf S500
Certification covers Zoom Rooms and Google Meet. That makes the S500 one of the few pucks you can drop into a Zoom Room or a Meet hardware space and expect the call controls to behave. Teams still works over USB audio, but without Teams-specific button features. If Teams is your standard, check our Microsoft Teams Rooms equipment guide before you buy.
Jabra Speak2 55
The 55 is certified for Teams, Google Meet and Amazon Chime, so mute and call controls stay in sync across those apps. The Teams model adds the Teams button. Jabra lists firmware and setup guides on its Speak2 55 support page.
