Plantronics Voyager 4320 | Wireless UC Headset for Microsoft Teams
We built the Plantronics Voyager 4320 for professionals who move between desk, home, and on-the-go work environments without missing a beat. This over-ear wireless headset pairs Microsoft Teams certification with adaptive active noise canceling, so your calls stay crystal-clear whether you’re in a quiet home office or a bustling café. The dual connectivity—Bluetooth 5.1 plus USB-A dongle—means you switch from laptop to mobile device in seconds, and our SoundGuard DIGITAL technology protects your hearing during those back-to-back video meetings.
With up to 24 hours of talk time on a single charge and leatherette ear cushions engineered for all-day wear, the Voyager 4320 is the UC headset we recommend when reliability and comfort matter most. Dynamic Mute Alert tells you when you’re speaking on mute, so you never waste time repeating yourself, and the swivel-to-mute boom arm makes toggling audio as natural as turning your head.
Wireless UC specifications
Adaptive ANC and SoundGuard Technology
The Voyager 4320 delivers two layers of audio intelligence that set it apart in the UC headset market. Adaptive active noise canceling monitors ambient sound in real time and adjusts suppression dynamically—walk from a quiet room into a noisy hallway and the headset recalibrates ANC within milliseconds. This means you stay immersed in the conversation without fiddling with manual controls.
SoundGuard DIGITAL sits beneath the ANC layer, protecting your hearing with anti-shock filters and acoustic limiting that meets regulatory standards for all-day use. If a sudden audio spike hits the line—feedback squeal, unexpected ringtone, dropped device—the headset clamps peak volume before it reaches your ear. We engineered this feature for contact-center agents and support reps who wear headsets eight hours a day, but every hybrid worker benefits from the same safeguards.
Microsoft Teams Certification and UC Platform Support
We earned Microsoft Teams certification for the Plantronics Voyager 4320, which means the dedicated Teams button on the left ear cup launches meetings, accepts calls, and surfaces notifications without toggling between windows. The certification also guarantees firmware-level optimization for Teams call quality, echo cancellation, and device pairing—your IT team won’t field tickets about audio dropouts or sync failures.
Beyond Teams, the headset works seamlessly with Zoom, Webex, Google Meet, and legacy softphone platforms. The USB-A dongle presents itself as a standards-compliant audio device, so plug-and-play compatibility extends to macOS, Windows, and most Linux distributions. If your organization runs a mixed UC environment, the Voyager 4320 adapts without requiring per-platform profiles.
Battery Life and Charging Behavior
We rate the Voyager 4320 at 24 hours of continuous talk time when ANC is disabled, dropping to roughly 20 hours with ANC active. Standby time stretches to 20 days, which means the headset holds a charge through a long weekend or short business trip without needing the cable. The USB-C charging port delivers a full charge in approximately 90 minutes, and a 15-minute quick charge adds three hours of talk time when you’re racing to join a call.
Battery telemetry flows into Plantronics Hub software, so you can monitor remaining runtime on your desktop or mobile device. The headset also announces battery level in your ear when you power on, eliminating the guesswork that leads to mid-call shutdowns. We designed the lithium-polymer cell for 500+ charge cycles before capacity degradation becomes noticeable—roughly two to three years of daily professional use.

Common Questions About the Voyager 4320
Yes. The Voyager 4320 is certified for Microsoft Teams but functions as a standard USB audio device and Bluetooth headset, so it works seamlessly with Zoom, Google Meet, Webex, Slack calls, and any other UC platform. You get the same call-control features and audio quality across all applications.
Download the free Plantronics Hub app for Windows, macOS, iOS, or Android. Connect your headset via the USB dongle or Bluetooth, launch Hub, and the software will notify you when a firmware update is available. Updates typically take three to five minutes and add new features or improve call quality. The headset must remain powered on and connected throughout the update process.
Yes. Plug in the USB-C charging cable and the headset continues to operate normally during calls. Charging while in use does not degrade audio quality or introduce noise. This passive-charge design means you can top up the battery during a long conference call without interrupting your workflow.
The BT700 USB dongle provides up to 30 meters of range in open space, though walls and interference from other 2.4 GHz devices reduce that distance. Bluetooth 5.1 direct pairing to your phone delivers roughly the same 30-meter range. In typical office environments expect reliable connectivity within 15 to 20 meters of your device.
The Voyager 4320 does not announce caller names or numbers. It plays a ringtone in your ear when a call arrives and you can answer by pressing the call button on the right ear cup. If you have Plantronics Hub running on your computer, incoming call notifications appear on-screen with caller details pulled from your UC platform.
When you speak while the microphone is muted, the headset detects your voice activity and plays a gentle alert tone in your ear. This reminds you to unmute before continuing. The feature works even when the headset is muted via the boom arm’s physical mute position, not just software mute in your UC app. You can disable the alert in Plantronics Hub if you prefer silent mute behavior.
No. The Voyager 4320 is designed exclusively for softphone UC applications via USB dongle and Bluetooth mobile pairing. It does not include a 2.5 mm or 3.5 mm analog cable for desk-phone connectivity. If you need desk-phone support, consider the Voyager 4310 variant or a model from the Savi series that includes a base station with desk-phone ports.
