Plantronics Voyager 4320 UC Wireless Headset
The Voyager 4320 UC is our premium dual-connectivity headset engineered for professionals who move between desk, video calls, and mobile throughout the day. With hybrid active noise canceling (ANC) and studio-quality microphones, it delivers crystal-clear conversations whether you're in a quiet home office or a bustling shared workspace.
We built the 4320 on a refined ergonomic frame with memory foam cushions and a padded headband that distributes weight evenly across the crown. The result is a headset you can wear comfortably through back-to-back meetings without pressure points or heat buildup.
Certified for Microsoft Teams and optimized for leading UC platforms, the Voyager 4320 integrates seamlessly into your collaboration stack. Dual Bluetooth 5.1 connectivity lets you pair simultaneously to your laptop and smartphone, so you never miss a mobile call while on a desk session. Our SoundGuard DIGITAL technology protects against acoustic shock and sudden loud noises, and the dedicated mute button gives you instant mic control during live calls.
What makes the Voyager 4320 stand out
Audio engineering and microphone performance
We equipped the Plantronics Voyager 4320 with 40 mm dynamic drivers tuned for both voice clarity and rich media playback. The frequency response extends from 20 Hz to 20 kHz, ensuring you hear every nuance in music and video while maintaining natural voice reproduction on calls.
The boom microphone uses three noise-canceling elements and advanced digital signal processing to isolate your voice from background chatter, keyboard clatter, and HVAC hum. During testing in open-plan environments, the mic consistently delivered clean audio with minimal ambient bleed, even when colleagues were talking a few feet away.
Dual connectivity and platform compatibility
Bluetooth 5.1 with multipoint pairing is the backbone of the Voyager 4320’s flexibility. Pair your Windows or Mac laptop for UC calls, then add your iPhone or Android phone as a second device. The headset intelligently prioritizes incoming mobile calls, pausing your desk audio and switching seamlessly when you answer.
Microsoft Teams certification means the dedicated Teams button launches the app, joins meetings, and raises your hand without touching your keyboard. LED indicators on the ear cup show your Teams presence status — red for busy, green for available — so coworkers know when you’re free. The headset also works flawlessly with Zoom, Google Meet, Cisco Webex, and RingCentral.
Comfort and all-day wearability
Memory foam ear cushions conform to the shape of your ears and create a gentle seal that enhances passive noise isolation. The cushions are wrapped in breathable leatherette that wicks moisture, so your ears stay cool even during marathon video sessions.
We designed the headband with a wide, padded crown piece that distributes the headset’s 185-gram weight evenly across the top of your head. Traditional narrow headbands concentrate pressure in a single line; our approach eliminates hot spots and reduces fatigue over eight-hour workdays.

Common questions about the Voyager 4320
The Voyager 4320 is designed for Bluetooth and USB connectivity to computers and mobile devices. It does not connect directly to traditional analog or digital desk phones.
If you need desk phone compatibility, consider the Plantronics Savi 8220 UC, which supports DECT wireless connections to both computers and desk phones with the appropriate base station. For a corded desk phone solution, the EncorePro series offers direct connectivity via quick-disconnect adapters.
The Voyager 4320 is a stereo (binaural) headset with cushions covering both ears, while the Voyager 4310 is a monaural headset worn on one ear. Both share the same Bluetooth 5.1 chipset, dual connectivity, Microsoft Teams certification, and 24-hour battery life.
Choose the 4320 if you want immersive audio for music and video, or if you work in noisy environments where passive isolation helps. The 4310 is better for professionals who prefer open-ear awareness or find over-ear designs too warm during long wear sessions.
Yes. The Voyager 4320 uses hybrid ANC with feedforward and feedback microphones to cancel ambient noise in your listening environment. ANC works continuously during calls, music playback, and standby.
You can toggle ANC on or off with the dedicated button on the left ear cup. When ANC is off, the headset switches to ambient mode, which pipes in environmental sound so you can hear conversations and alerts around you without removing the headset.
The optional USB-A dongle provides up to 98 feet (30 meters) of wireless range in open environments. Actual range depends on obstacles like walls, metal furniture, and wireless interference from other devices.
Direct Bluetooth pairing to your laptop or phone typically delivers 30 to 50 feet of range. The dongle is recommended if you move around a large office or need reliable connectivity beyond typical Bluetooth limits.
The headset supports multipoint pairing to two devices simultaneously — for example, your laptop and smartphone. You can store pairing profiles for up to eight devices in memory, but only two can be actively connected at one time.
To switch between stored devices, power off the headset, then power it back on while holding the Bluetooth button. The headset will cycle through paired devices and announce each one until you hear the device you want to connect.
No, the boom microphone is permanently attached to the headset frame. It rotates 330 degrees and locks in any position, so you can wear it on your left or right side or flip it up out of the way when not in use.
A magnetic sensor detects when the boom is raised and automatically mutes the microphone. This gives you a physical indicator that you're off-air and prevents accidental open-mic moments during video calls.
SoundGuard DIGITAL is our proprietary acoustic protection system that shields your hearing from sudden loud noises and acoustic shock events. The technology continuously monitors incoming audio levels and applies dynamic limiting to keep peaks below safe thresholds.
If a colleague accidentally drops their phone near a speakerphone mic or a teleconference experiences feedback, SoundGuard DIGITAL clamps the volume instantly to protect your ears. The system meets EU and US occupational safety standards for daily noise exposure in professional headset use.
