We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired, no-fuss headset with binaural stereo and active noise cancellation on a 3.5 mm jack, choose PLT Plantronics Plnhw520; if you need a wireless Bluetooth headset with a noise-canceling boom mic, long battery life, and a charge stand for hybrid work, choose Amazon Renewed Poly Voyager 4320.
• PLT Plantronics Plnhw520 — biggest strength: true wired reliability with binaural supraaural over-ear cups, a 3.5 mm jack, and active noise cancellation for a fixed desk setup.
• PLT Plantronics Plnhw520 — biggest trade-off: it's a corded headset with no Bluetooth, so you're tethered to whatever the cable reaches.
• Amazon Renewed Poly Voyager 4320 — biggest strength: wireless freedom via Bluetooth 5.2 with up to 50 m of range, 24 hours of battery, a noise-canceling boom mic, and a charge stand.
• Amazon Renewed Poly Voyager 4320 — biggest trade-off: it's a renewed unit with passive noise cancellation only, and it depends on charging and Bluetooth rather than a simple cable.
• Who each pick is for: the Plantronics for someone who wants a plug-in-and-talk wired stereo headset that never needs charging; the Poly for someone who moves between home, office, and phone calls and wants a wireless boom-mic solution.
The Plnhw520 is the headset you reach for when you want zero moving parts. It's binaural, meaning both ears get audio, and the supraaural over-ear fit with aluminum enclosure construction gives it a solid, utilitarian feel. The connection is wired through a 3.5 mm jack, and the model name — EncorePRO HW520 — points to Plantronics' business-headset lineage, which is exactly the environment this thing was built for. There's no pairing, no battery indicator, no charging ritual. You plug it in and it works.
On the noise side, the Plnhw520 lists active noise cancellation, and its closed over-ear design helps physically block some surrounding sound as well. The audio specs back up a voice-first tuning: 20 Hz to 16 kHz frequency response, 320 ohm impedance, 40 dB sensitivity, and a dynamic driver. That combination leans toward clear speech reproduction rather than thumping bass, which is what you want on a call. There's a volume control on the headset and a Quick Disconnect system, so you can detach the cable without yanking the whole headset off — a genuinely useful detail if you're wearing it all day and stepping away between meetings.
Who should buy it? In my opinion, this is for the person with a fixed workstation — a desk, a docking setup, a landline-style work rhythm — who is tired of Bluetooth dropouts and dead batteries. It also suits anyone who wants a simple wired stereo headset that just stays where it's plugged in. Who should skip it? Anyone who takes calls while walking around, wants to connect to a phone wirelessly, or needs a boom mic that actively cancels their background noise. This headset is about consistency, not mobility.
The Voyager 4320 is the opposite philosophy: cut the cord and handle noise at the microphone. Its headline feature is a noise-canceling dual mic with Acoustic Fence technology on a flexible boom arm, designed so the people on the other end hear your voice and not the room around you. There's also a pinch-to-mute button on the boom and a dynamic mute alert that tells you when your mic is silenced — small touches that matter when you're on back-to-back calls and can't risk an open mic.
Connectivity is where it earns its keep. It pairs wirelessly through the included BT700 USB-C Bluetooth adapter, with a USB-C to USB-A adapter in the box for older ports, and it also connects to a phone over Bluetooth 5.2. The stated Bluetooth range is up to 50 meters, so you can walk to the kitchen mid-call without dropping. Battery life is rated at 24 hours, and the bundle includes a charge stand, so the headset has a home on your desk rather than a cable dangling off your laptop. At 162 g with an adjustable padded headband and memory foam ear cushions, it's built to be worn through a long workday.
This is a hybrid-work headset, plainly. The travel pouch, the Microsoft Teams button, and the stated integration with Zoom and similar platforms point to someone who bounces between a home desk and an office desk and lives inside a video-calling app. Noise control here is passive — the over-ear cups and cushioning isolate you from your surroundings — while the active noise work happens at the mic. That's an important distinction: it quiets your background for callers, not the world for you. And because this is a renewed unit, it carries a 90-day limited warranty rather than the longer coverage a new unit would come with. If you're comfortable with renewed hardware and want wireless range plus a serious boom mic, it fits. If you want a brand-new sealed product or you hate charging things, it doesn't.
Side-by-Side: Which Should You Choose?
• Best for a fixed desk setup → PLT Plantronics Plnhw520. Wired 3.5 mm connection, no charging, no pairing.
• Best for mobility → Amazon Renewed Poly Voyager 4320. Bluetooth 5.2 with up to 50 m range and 24-hour battery.
• Best for blocking your background noise from callers → Amazon Renewed Poly Voyager 4320. The dual noise-canceling boom mic with Acoustic Fence does that job.
• Best for canceling sound around you → PLT Plantronics Plnhw520. It's the one listed with active noise cancellation.
• Best for never thinking about batteries → PLT Plantronics Plnhw520. No battery at all; it draws from the device it's plugged into.
• Best for long-wear comfort specs → Amazon Renewed Poly Voyager 4320. Adjustable padded headband and memory foam cushions at 162 g.
• Best for the simplest possible ownership → PLT Plantronics Plnhw520. One cable, one jack, done.
I'd buy the Amazon Renewed Poly Voyager 4320 for most modern office and hybrid setups. In my opinion, the combination of a noise-canceling boom mic, 24-hour battery, 50 m Bluetooth range, a charge stand, and Teams integration covers the way people actually work now — moving between rooms, apps, and devices. The Plnhw520 is a fine, honest wired headset with active noise cancellation, but its cable and lack of a boom mic make it a desk-bound tool. If your job is a fixed station and you never want to charge anything, take the Plantronics. Otherwise, the Poly is the more flexible pick.
what is noise cancelling headset
A noise-cancelling headset reduces unwanted sound in one of two ways. Active noise cancellation uses electronics to counter ambient sound around your ears — the PLT Plantronics Plnhw520 is listed with that. Passive noise cancellation relies on physical isolation, like the over-ear cushions and padded fit on the Poly Voyager 4320, which also uses a noise-canceling boom mic to keep your background out of your callers' ears.
wired or wireless headset for office noise
It depends on what you're fighting. For noise around you at a fixed desk, the wired Plnhw520 with active noise cancellation makes sense. For noise you're transmitting to callers — barking dogs, keyboards, a busy room — the Voyager 4320's noise-canceling dual mic with Acoustic Fence is the more direct fix, and its 50 m Bluetooth range lets you step away without unplugging.
how long does the Poly Voyager 4320 battery last
The battery is rated at an average life of 24 hours. The bundle also includes a charge stand, so in practice you park it on the stand between calls and top it up rather than running it flat. Compare that to the Plnhw520, which has no battery at all because it's a wired headset.
does the Plantronics Plnhw520 need Bluetooth
No. It connects over a 3.5 mm wired jack and has no wireless technology listed. That's the appeal: no pairing, no charging, no dropouts. If you need Bluetooth to a computer or phone, the Voyager 4320 is the one built for that, using an included BT700 USB-C adapter or Bluetooth 5.2.
