For small rooms and laptop calls, the best "conference microphone" is usually a USB speakerphone with Bluetooth: the Jabra Speak2 75 for huddle and small rooms, the Poly Sync 60 when you need more pickup, and the Jabra Speak2 55 or Poly Sync 20 for one to three people. Use USB in a fixed room; use Bluetooth for phones and travel.
Why a speakerphone beats a standalone mic
A bare USB microphone captures the room but does nothing about the far end's voices coming out of your laptop speakers. That creates echo. A conference speakerphone combines microphones, a speaker and echo cancellation in one device, so the call software gets clean audio without a separate mixer. For rooms up to about six people, it is the simplest setup that sounds right.

USB vs Bluetooth: which to use
USB is the right default for a room computer or a laptop on the table. It is stable, needs no pairing, and the call app sees the speakerphone as both mic and speaker.
Bluetooth is best for mobile phones and for laptops when you want no cable. Two cautions:
- A laptop's built-in Bluetooth can drop to a lower-quality headset mode when the microphone is in use. A dedicated USB Bluetooth adapter, like the Jabra Link 370 that pairs with the Speak 750, avoids most of those problems.
- Battery-powered units in a shared room get left uncharged. If the device lives in one room, keep it on USB power.
How big a room can one speakerphone cover?
| Room | People | Recommendation |
|---|---|---|
| Desk / focus room | 1-2 | Poly Sync 20, Jabra Speak2 55 |
| Huddle room | 2-4 | Jabra Speak2 75, Poly Sync 40, Jabra Speak 750 |
| Small room | 4-6 | Poly Sync 60, Jabra Speak2 75 |
| Medium room | 6-10 | Two daisy-chained AVer FONE540 units, or move to a room system |
Past six to eight people around a table, a single puck struggles to hear the far seats. At that point look at a video bar with expansion mics or a ceiling mic. Our conference room microphone guide and ceiling microphone picks cover those options.
Need video too?
If the room needs a camera, a video bar replaces the speakerphone. The Logitech ConferenceCam Connect is a portable camera-plus-speakerphone for small groups, and our best video bars guide covers fixed rooms.
Buying checklist
- Certified for your platform (Teams, Zoom) if you want the call controls to work reliably.
- USB-C and USB-A support, or an included adapter.
- Mute button that syncs with the call app.
- Enough mics for the table size.
- For shared rooms: a cable lock or a fixed USB connection to the room PC.
