If you want a wireless, all-day headset that lets you walk away from your desk while staying on the call, choose Yealink WH62; if you need a wired, plug-and-play headset that connects to almost anything you already own, choose PLT Poly Blackwire 5220. That's the whole decision in one line. Everything below is the reasoning behind it.
• Yealink WH62 — biggest strength: DECT 6.0 wireless with up to 525 ft of range and 13 hours of talk time, so you can take calls away from your desk for a full workday.
• Yealink WH62 — biggest trade-off: It's a wireless system with a base, so it needs power and a desk it lives on. It's not the headset you toss in a bag for the commute.
• PLT Poly Blackwire 5220 — biggest strength: Wired USB-C / USB-A / 3.5 mm connectivity in one package. No battery, no base, no pairing — plug it into whatever is in front of you.
• PLT Poly Blackwire 5220 — biggest trade-off: It's wired, so you're tethered by a 7.1 ft cable and there's no wireless freedom.
• Who each is for: Hybrid and desk-based workers who take long calls and want to move around → Yealink WH62. Office workers on mixed devices who want zero setup and zero charging → PLT Poly Blackwire 5220.
The Yealink WH62 is built around one idea: get up and keep talking. It uses DECT 6.0 wireless, not Bluetooth, and the spec sheet lists a range of up to 160 m / 525 ft. That's the kind of range that covers a house, a floor of an office, or a warehouse aisle — not just the six feet between your chair and your monitor. If you've ever been trapped at your desk because your headset died or dropped out, that number is the whole reason to care about this headset.
Battery is the other headline. The mono version is rated for 13 hours of talk time, with a 2.5-hour charge. A full workday of calls is roughly 8 hours, so 13 hours gives you real headroom — you can forget to dock it overnight and still get through most of the next day. Audio is a single dynamic driver covering 20 Hz to 20,000 Hz, with passive noise cancellation and dual noise-canceling microphones using Yealink's Acoustic Shield technology to filter background noise. There's a busylight so colleagues can see you're on a call, and you can mute by flipping the mic or pressing a button.
Comfort is where a headset lives or dies over a long day, and the WH62 is light: 0.18 lb for the single-ear version and 0.28 lb for dual, with a memory foam ear cushion and an adjustable padded headband. It's an on-ear, single-speaker mono design, so if you like having one ear open to your surroundings, that's a plus.
Who should buy it: hybrid workers, people on back-to-back calls, and anyone who wants to walk to the kitchen mid-meeting. It's Teams/UC certified, plugs into a computer or desk phone, and enters Teams with one click. There's a long compatibility list of Yealink desk phones, plus Poly VVX and SNOM phones via the optional EHS35 adapter — worth checking your phone is on it before you buy.
Who should skip it: if you work from a hot desk, a café, or a shared laptop you carry around, the base and charging routine are friction you don't need. And if you only ever sit at one desk, you're paying for wireless freedom you won't use.
The Blackwire 5220 is the opposite philosophy, executed well. It's wired. It ships with a USB-C / USB-A adapter and also offers a 3.5 mm mini-phone connection, so the same headset works on a laptop, a desktop, a phone with a headphone jack, and most anything else with a port. There's no battery to charge, no base to plug in, no pairing step. You take it out of the box and it works.
The design is over-the-head, binaural — two ears covered — with faux leather ear cushions and a foldable build that packs into the included carrying case. Poly's own description leans on passive noise canceling from conforming ear cushions and a tuned microphone that masks nearby conversations. That's the honest framing: this is passive isolation, not active noise cancellation, and the spec sheet lists noise control as sound isolation rather than ANC.
Audio specs are straightforward: a dynamic driver, 32 ohm impedance, and a 20 Hz to 20 kHz frequency range. The 32 ohm impedance matters if you ever plug into a 3.5 mm jack — it's an easy load for phones and laptops to drive. The cable runs 7.1 ft, which is generous enough to stand up at your desk without yanking the headset off your head.
Who should buy it: office workers and call-center folks on fixed desks, people who rotate between a laptop and a desk phone, and anyone who hates charging things. It's Microsoft Teams certified and TAA-compliant, which matters if you're buying for government or contract work. The fold-flat design and case make it a genuinely portable wired headset.
Who should skip it: if you pace during calls, take meetings while walking, or split time between two rooms, the cable will annoy you fast. And if you want to keep one ear open to the office, the binaural over-ear fit blocks that out.
• Best for wireless freedom → Yealink WH62. 525 ft of DECT range versus a 7.1 ft cable. Not close.
• Best for battery life → Yealink WH62. 13 hours of talk time and a 2.5-hour charge, enough for a full day of calls.
• Best for zero setup and zero charging → PLT Poly Blackwire 5220. No battery, no base, no pairing — plug in and go.
• Best for connecting to lots of different devices → PLT Poly Blackwire 5220. USB-C, USB-A, and 3.5 mm in one package, so it covers laptops, desktops, and phones.
• Best for long calls in one spot → PLT Poly Blackwire 5220. Over-ear passive isolation and a 7.1 ft cable make it a comfortable desk-bound workhorse.
• Best for moving around the office or home → Yealink WH62. The busylight and flip-to-mute mic fit a shared space where people need to see you're busy.
• Best for a single-ear, open-ear feel → Yealink WH62. The mono design keeps one ear free to hear what's going on around you.
• Best for people who hate charging routines → PLT Poly Blackwire 5220. A wired headset can't run out of battery mid-call.
In my opinion, most people shopping this comparison should buy the Yealink WH62. The reason is simple: wireless range and a 13-hour battery solve the two problems that actually ruin a workday — being stuck at your desk and running out of power mid-call. If you're hybrid, on back-to-back calls, or just tired of a leash, that freedom is worth the base and the charging habit.
I'd recommend the PLT Poly Blackwire 5220 instead if you're desk-bound, bounce between multiple devices, or simply refuse to think about charging anything. It's the lower-maintenance choice. If you're unsure, decide one thing first: do you need to walk away from your desk while talking? If yes, WH62. If no, Blackwire 5220.
FAQ
Yes. It uses DECT 6.0 wireless technology, not Bluetooth, with a range of up to 160 m / 525 ft. That's a longer, more stable connection than most Bluetooth headsets, but it requires the included base and a power source.
No. It's a wired headset, so there's nothing to charge and no talk-time limit. It connects over USB-C, USB-A via the included adapter, or a 3.5 mm jack, depending on what you plug it into.
Neither offers active noise cancellation. The Yealink WH62 uses dual noise-canceling microphones and passive noise cancellation, so callers hear less of your background. The Poly Blackwire 5220 relies on passive isolation from its ear cushions and a tuned microphone. For blocking out a loud office, the over-ear Blackwire 5220 has the edge on isolation; for cleaning up your outgoing voice, the WH62's dual-mic setup is the stronger design.
