How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired, work-first headset you can plug into a PC, a phone and a tablet without ever thinking about charging, choose Plantronics Poly Blackwire 5220; if you need true active noise cancellation, all-day wireless freedom and a fit that survives running and gym sessions, choose occiam Active Noise Cancelling. These two are built for completely different buyers, and once you see that, the decision gets simple fast.
• Plantronics Poly Blackwire 5220 — biggest strength: wired USB-C plus 3.5 mm connectivity with a tethered USB-A adapter, so it works across PC, mobile and tablet with zero pairing and zero battery anxiety.
• Plantronics Poly Blackwire 5220 — biggest trade-off: it is a wired on-ear headset with passive noise cancellation only, so it dampens nearby chatter but does not electronically cancel noise, and you are tethered to your device.
• occiam Active Noise Cancelling — biggest strength: genuine active noise cancellation rated to reduce ambient noise by up to 45dB, with a combined playback figure of up to 90 hours when you use one earbud at a time.
• occiam Active Noise Cancelling — biggest trade-off: it is fully wireless and Bluetooth-only, so you depend on charging and pairing, and the in-ear hook design suits movement better than a desk.
• Buy the Plantronics Poly Blackwire 5220 if you live on calls at a desk and want one headset that just plugs in and works.
• Buy the occiam Active Noise Cancelling if you want ANC on the move — commuting, running, the gym — and hate cables.
The Blackwire 5220 is a desk-and-desk-hopping work headset, and its whole design says so. It connects by USB-C with a tethered USB-A adapter for computers, and it also has a 3.5 mm jack for mobile or tablet use. That means you can move between a laptop, a phone and a tablet during the day without re-pairing anything. There is no wireless technology listed here at all — this is a wired headset, and that is the point.
The comfort story is built around long sessions. The earcups are on-ear, wrapped in leatherette with memory foam underneath, and the whole thing weighs 5.76 ounces. On-ear leatherette cushions are the classic choice for back-to-back calls because they seal well enough to take the edge off office noise without clamping like over-ears. Poly calls this passive noise cancellation: soft conforming cushions plus a precisely tuned boom microphone that masks nearby conversations. The boom mic is the other half of the pitch — your voice is picked up close to your mouth, which is exactly what you want on calls where the person on the other end matters more than your music.
Controls sit on the earpiece: call, answer, end, mute and volume, all touch-controlled. The headset also folds up and ships with a carrying case, so it survives a commute in a bag. Plantronics backs it with a 2-year manufacturer warranty.
Who should buy it: remote and office workers, support and sales people, anyone who takes a lot of voice calls and wants a plug-and-play headset with a real microphone and no charging routine. Who should skip it: anyone who wants active noise cancellation, wireless freedom, or a headset for running and workouts. The cable and the on-ear fit are not made for the treadmill.
The occiam Active Noise Cancelling earbuds are the opposite personality: wireless, sporty and built to move. They use Bluetooth 5.4 with a stable connection within roughly 30 feet, and they pair by simply opening the case thanks to a hall switch — auto power-on and instant reconnect to your last device after the first pairing. Compatibility covers smartphones, TVs, computers and laptops, and you can run them in binaural mode or mono with either earbud on its own.
The headline feature is real active noise cancellation. occiam rates it at up to 45dB of ambient noise reduction, with high-sensitivity microphones for call clarity. On a subway, a busy street or in a loud open office, that is a meaningful difference from passive isolation — it is electronics doing the work, not just foam pressing against your ear. The earbuds also support mono mode, so you can keep one ear open to the world while the other handles a call or a podcast.
Battery is where these pull away from most rivals. Each earbud plays about 8 hours on a charge. Use both together with the case and you get around 48 hours; rotate one earbud at a time and the total climbs to as much as 90 hours. The case charges over USB-C and has a digital display so you can see remaining power instead of guessing. A two-hour charge time is listed, so a top-up is an overnight or desk-session affair, not a two-minute emergency.
For fit, occiam goes sport-first. Flexible soft ear hooks keep the buds locked in place, and there are three ear tip sizes (S, M, L) so you can dial in the seal — which matters doubly here, because a good seal is what makes ANC work well. The IPX7 waterproof rating covers sweat, splashes and rain, which is exactly the spec you want for running, jogging and gym work. Controls are physical push buttons on each earbud for play/pause, volume and calls, which is more reliable than touch when your hands are sweaty. One quirk worth knowing: in mono mode you cannot adjust volume from the button, only from your phone. occiam also backs these with a 2-year warranty.
Who should buy them: runners, gym-goers, commuters and anyone who wants wireless ANC with serious battery life. Who should skip them: desk-based callers who want a boom microphone and a wired connection that never needs charging — that is not what these are for.
• Best for call quality at a desk → Plantronics Poly Blackwire 5220. The boom microphone sits at your mouth; earbuds with built-in mics cannot match that positioning for voice pickup.
• Best for noise cancellation → occiam Active Noise Cancelling. Up to 45dB of active reduction versus passive cushioning only.
• Best for battery life → occiam Active Noise Cancelling. Up to 90 hours total with single-earbud rotation, versus a wired headset that needs no charging at all but cannot leave the cable.
• Best for workouts and running → occiam Active Noise Cancelling. Ear hooks, three ear tip sizes and IPX7 water resistance are built for sweat.
• Best for multi-device work → Plantronics Poly Blackwire 5220. USB-C, a USB-A adapter and 3.5 mm cover PC, mobile and tablet without pairing.
• Best for commuting → occiam Active Noise Cancelling. Wireless, compact case, ANC for trains and streets.
• Best for zero-maintenance reliability → Plantronics Poly Blackwire 5220. No battery, no pairing, no firmware — plug in and talk.
• Best for portability → occiam Active Noise Cancelling. A small charging case and two tiny buds beat a folded on-ear headset in a bag.
If I had to pick one, I would buy the Plantronics Poly Blackwire 5220 — because my day is calls, and a wired boom-mic headset that works across every device without charging is the tool that actually fits that job. In my opinion, the occiam Active Noise Cancelling is the better buy only if your priority is ANC, wireless freedom and workout-proof battery life. Match the product to your day and neither one disappoints. Check the current price on Amazon before you commit, since pricing moves around.
No. It is a wired headset with USB-C, a tethered USB-A adapter and a 3.5 mm jack. There is no wireless technology listed, which is why it never needs charging or pairing.
occiam rates them for up to 45dB of ambient noise reduction through active noise cancellation. That is electronic cancellation, so it handles steady background noise like trains and crowds better than passive cushioning alone.
Yes, they have built-in high-sensitivity microphones and support mono mode for one-ear use. But for all-day desk calls, a boom microphone like the Blackwire 5220's usually picks up your voice more cleanly.
The occiam Active Noise Cancelling, clearly. Ear hooks, three ear tip sizes and IPX7 water resistance are designed for sweat and movement, while the Blackwire 5220 is an on-ear wired headset meant for desks.
