If you want a corded, plug-and-play headset that works the moment you plug it into a USB port, choose Plantronics Blackwire C3220; if you need to move around the room untethered with a single-ear design and a boom mic, choose Voistek Headset.
• Plantronics Blackwire C3220 — biggest strength: Wired USB connectivity with no battery anxiety, no pairing, and a lightweight over-ear build that weighs just 118 g.
• Plantronics Blackwire C3220 — biggest trade-off: The cable anchors you to the desk, and it's a USB-only connection with no Bluetooth option.
• Voistek Headset — biggest strength: Bluetooth 5.3 plus an included USB dongle, up to 50 hours of claimed talk time, and a 15 m wireless range so you can stand up mid-call.
• Voistek Headset — biggest trade-off: You're relying on a battery, and wireless headsets always introduce a charging routine the corded option never needs.
• Pick Plantronics Blackwire C3220 if you sit at one desk all day and want zero setup friction.
• Pick Voistek Headset if you split your time between a PC, a laptop and a phone, and you want one headset that follows you.
The Blackwire C3220 is a corded UC headset built around one idea: eliminate everything that can go wrong before a call. There's no pairing, no charging, no dongle to lose. You plug the USB connector in and you're live. That simplicity is the whole pitch, and for a lot of office setups it's exactly right.
On paper the audio side is sensible rather than exotic. A dynamic driver with a 20 Hz–20 kHz frequency range and 32 ohm impedance is the standard profile for voice work, and the passive noise cancellation is there to take the edge off office chatter rather than to silence a call centre floor. The over-ear, supra-aural fit sits on the ear rather than around it, which keeps the 118 g weight feeling light across a long shift. A remote control handles your call functions, so you're not hunting through software menus mid-conversation.
Who should buy it? Anyone parked at a single workstation — a reception desk, a trading floor seat, a support pod — where the headset lives plugged in and never travels. The USB-only connection means it pairs naturally with a work laptop or desktop that stays put. If your job is answering calls for eight hours and you never want to think about battery percentage again, this is the profile you want.
Who should skip it? If you take calls while walking to the kitchen, join meetings from a phone, or move between rooms, the cable becomes a leash fast. There's no Bluetooth here, so a tablet or a mobile-only workflow is out. And if you need true active noise cancellation rather than passive isolation, this isn't that product.
The Voistek Headset is designed for the opposite problem: mobility. It's a single-ear, on-ear wireless headset with Bluetooth 5.3 and a 15-metre range, so you can stand up, refill a glass of water, and keep talking without dropping the call. The included USB dongle matters more than it sounds — it lets you connect to a non-Bluetooth Windows PC or MacBook without fighting your operating system's Bluetooth stack, which is the single most common headache with wireless headsets at work.
The spec sheet points at long sessions. A 40 mm dynamic driver, 16 ohm impedance and a 20 Hz–20 kHz range give it a fuller low end than a typical voice-only headset, and the claimed battery life runs up to 50 hours with a 2-hour charge time. In practical terms that's a work week of calls between charges for most people, which removes the daily charging ritual. The flexible boom mic with noise cancelling is aimed squarely at Zoom, Teams and customer-support work, and there's a dedicated mute button plus push-button media controls for quick volume and privacy.
Comfort is where the single-ear design earns its keep. On-ear with an adjustable headband and soft padding means one ear stays open to your surroundings — genuinely useful in a shared office or if you need to hear a colleague or a doorbell. The build mixes ABS, aluminium and faux leather, and the package includes the headset, a USB A-to-C adapter cable, the dongle and a manual.
Side-by-Side: Which Should You Choose?
• Best for zero-setup reliability → Plantronics Blackwire C3220. USB wired means it works the second you plug it in, every time.
• Best for mobility → Voistek Headset. Bluetooth 5.3 with a 15 m range lets you leave the desk mid-call.
• Best for long battery life → Voistek Headset. Up to 50 hours claimed talk time on a 2-hour charge.
• Best for cross-device use → Voistek Headset. Bluetooth plus the USB dongle covers PCs, Macs and phones; the Blackwire is USB only.
• Best for one-ear awareness → Voistek Headset. The on-ear single-side design keeps you in touch with your surroundings.
• Best for lightweight feel → Plantronics Blackwire C3220. At 118 g it's the lighter of the two, and there's no battery adding bulk.
• Best for a fixed desk job → Plantronics Blackwire C3220. No charging routine, no pairing, no dongle to misplace.
• Best for richer audio on music between calls → Voistek Headset. The 40 mm driver and 16 ohm impedance lean warmer than a pure voice headset.
In my opinion, most people shopping this comparison should buy the Voistek Headset. The combination of Bluetooth 5.3, a USB dongle for stubborn PCs, up to 50 hours of claimed battery, and a single-ear design that works across laptop, desktop and phone covers far more real-world work setups in 2026. The Blackwire C3220 is the better pick only if you are genuinely desk-bound and value never thinking about a battery again — and for that specific person it's excellent. Everyone else gets more flexibility from the Voistek. Check the current price on Amazon before you commit, since that's the one variable that can flip this decision.
No. It's a wired USB headset with no Bluetooth. You plug it into a USB port and it stays tethered, which is the trade-off for never needing to charge it.
The spec sheet claims up to 50 hours of talk time, with a 2-hour charge time. Real numbers vary with volume and call length, but that's a week of typical office use between charges.
Yes. It ships with a USB dongle specifically for that. You can also use Bluetooth 5.3 on phones and Bluetooth-capable laptops, and the box includes a USB A-to-C adapter cable.
For a fixed desk, I'd pick the Blackwire C3220 for its wired reliability and 118 g weight. If you move around, take calls on multiple devices, or want one ear free, the Voistek Headset is the more practical choice.
