If you want a wired headset that moves between a laptop, a desk phone setup and a mobile device with one flexible connection story, choose PLT Poly Blackwire 3325; if you need an office headset built around Microsoft Teams call control and a visible busy light that tells coworkers you're on a call, choose TruVoice VoicePro 80.
• PLT Poly Blackwire 3325 — biggest strength: true multi-device flexibility, with USB-C, a USB-C to USB-A adapter in the box, and a 3.5 mm jack for mobile, plus a dedicated Teams button and an adjustable 180-degree pivoting speaker design.
• PLT Poly Blackwire 3325 — biggest trade-off: no active noise cancellation and no busy light, so it leans on passive comfort and voice pickup rather than blocking out a noisy room or signalling your status to people nearby.
• TruVoice VoicePro 80 — biggest strength: Teams-specific workflow features, including an illuminated focus light that glows red during a Teams call and in-line call control for answering, ending, muting and adjusting volume.
• TruVoice VoicePro 80 — biggest trade-off: connectivity is USB-C only, with no 3.5 mm option, and the higher 300-ohm impedance means it expects a proper USB audio source rather than a simple analog jack.
• Who each pick is for: the Blackwire 3325 suits hybrid workers juggling several devices; the VoicePro 80 suits office and call-center users who live inside Teams all day.
The Blackwire 3325 is a wired, over-ear headset with a plush padded headband and pillow-soft ear cushions, and its defining trait is connection flexibility. You can run it into a PC or Mac over USB-C, switch to USB-A using the included adapter, or plug straight into a mobile device through the 3.5 mm jack. That single headset covers three scenarios that usually need two or three different products.
The physical design backs up the everyday-use angle. The speakers pivot up to 180 degrees, so you can lay the headset flat for storage or angle the earcups to sit the way you want, and the flexible microphone boom lets you position the mic close to your mouth for consistent voice pickup. Frequency response runs 20 Hz to 20,000 Hz with 32-ohm impedance and 116 dB sensitivity, which is the sort of spec profile that plays nicely with phones, laptops and tablets rather than demanding a dedicated amplifier.
This is the headset I'd point a hybrid worker toward. If your day bounces between a work laptop, a personal machine and a phone, the Blackwire 3325 means one headset and no dongle hunting. The Microsoft Teams version adds a dedicated Teams button for jumping into the app, which keeps the workflow tight during busy meeting days.
TruVoice VoicePro 80: Who It's For
The VoicePro 80 takes the opposite approach: instead of chasing every device, it doubles down on the office and call-center workflow. Its headline feature is the Teams focus light — a fully illuminated LED that turns red when you start a Microsoft Teams call and stays red for the duration. That's a genuinely practical design choice. Anyone who has been tapped on the shoulder mid-sentence by a colleague knows the value of an unambiguous visual signal that you're on a call.
Call handling is built into the cable rather than the software. In-line controls let you answer and end calls, adjust volume and mute the microphone with a button press, which matters when you're mid-conversation and don't want to hunt through windows on screen. The microphone boom rotates up to 330 degrees, so you can swing it out of the way when you're not talking or wear the headset on either side without fighting the mic position.
Audio is pitched at voice work. The noise-canceling microphone is paired with acoustic shock protection, a feature aimed at sudden loud spikes on the line — the kind of thing call-center buyers care about. The ear cups are over-ear with breathable cushions and a padded headband, and the frame pairs high-quality plastics with a metal reinforcement, which speaks to durability in a shared or high-turnover desk environment. Frequency range is again 20 Hz to 20,000 Hz, with dynamic drivers and 300-ohm impedance. Note that the listing also states active noise cancellation in its feature set, which is unusual for a wired USB headset and worth confirming against the product page if isolation is your priority.
Compatibility is broad on the software side: Teams is the focus, but it's stated to work with Windows applications including Skype and Zoom, plus softphones from Avaya, Cisco, RingCentral and Dragon. Connection is USB-C, and the box includes both USB-A and USB-C options plus ear cushions, a headband and a user manual.
Skip it if you need analog or 3.5 mm connectivity, or if you're a hot-desker who wants one headset for a phone call on the train and a Teams meeting at the desk. USB-C-only is a real limitation.
• Best for multi-device flexibility → PLT Poly Blackwire 3325. USB-C, USB-A via adapter and 3.5 mm in one headset.
• Best for Teams call workflow → TruVoice VoicePro 80. Dedicated focus light plus in-line answer, end, mute and volume controls.
• Best for open-plan office signalling → TruVoice VoicePro 80. The red focus light does the "do not interrupt" job for you.
• Best for hybrid and travel use → PLT Poly Blackwire 3325. The 3.5 mm jack and 32-ohm impedance suit phones and laptops alike.
• Best for durability in a shared or call-center setting → TruVoice VoicePro 80. Metal-reinforced frame with breathable over-ear cushions.
• Best for someone who hates dongles and adapters → PLT Poly Blackwire 3325. The adapter ships in the box and the pivoting speakers pack flat.
• Best for laptop-only softphone users → either works, but the VoicePro 80 gives you more control at the cable and the Blackwire 3325 gives you more device reach.
• Best for buyers who want to compare real cost → check the current price on Amazon for both, since the two sit in different feature tiers and the value call depends on what you're paying.
If I had to pick one, I'd take the TruVoice VoicePro 80 — but only if your working life is genuinely Teams-centric. The focus light and in-line call control are the kind of features that quietly remove friction dozens of times a day, and the metal-reinforced frame suggests it will survive being passed around an office. The USB-C-only connection is the price of admission, and for a desk-bound user that's fine.
If you move between devices, or you take calls on your phone as often as your laptop, I'd go the other way and buy the PLT Poly Blackwire 3325. Its connection flexibility and lighter 32-ohm design make it the more adaptable headset, and the flexible boom plus pivoting speakers make it easy to live with. In my opinion, that's the better pick for a hybrid worker who wants one headset to do everything.
Not universally. The Blackwire 3325 wins on connectivity — USB-C, USB-A via adapter and 3.5 mm — while the VoicePro 80 wins on Teams-specific features like the red focus light and in-line call control. Pick based on your workflow, not on a single winner.
It connects over USB-C and the listing states it works with cell phones that have a USB-C connection, plus softphones and Windows apps like Teams, Skype and Zoom. It does not offer a 3.5 mm jack, so older phones with analog audio are out.
The VoicePro 80 is the more office-oriented design, with a noise-canceling microphone, acoustic shock protection and a stated active noise cancellation feature. The Blackwire 3325 has no noise control listed, so it relies on the fit of its on-ear cushions for passive isolation.
If you're mostly on a laptop and use Teams all day, the VoicePro 80's call controls and focus light are genuinely useful at a home desk. If you switch between a work laptop, a personal computer and a phone, the Blackwire 3325's three connection options make it the more practical home-office pick.
