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.
