HP/Poly specifically lists Acoustic Fence microphone noise cancellation, which is one of the headset's strongest features for office/meeting calls.

What I particularly like

1. Excellent for voice calls
The boom microphone and Acoustic Fence technology are designed to reduce surrounding office noise. If your primary use is business calls rather than music, this is a strong choice.

2. USB dongle is useful
The included BT700 adapter gives you a dedicated wireless connection to your PC. You don't have to depend on the PC's built-in Bluetooth.

3. Good battery life
Up to 24 hours talk time with the online indicator off, or 18 hours with it on.

4. Works with phone + PC
You can use Bluetooth with your smartphone and the BT700 adapter with your computer.

5. Good for long working days
It's relatively lightweight and uses an on-ear stereo design rather than a heavy gaming-headset design.

One important point

There are several Voyager 4320 variants:

• 4320 UC USB-A — BT700 USB-A dongle
• 4320 UC USB-C — BT700 USB-C dongle
• 4320 UC USB-C/A — adapter supporting both
• 4320-M — Microsoft Teams-oriented variant

So when buying, check whether the package contains BT700 USB-A or USB-C. HP currently lists both versions.
