If you want maximum flexibility and a stereo, plug-and-play headset you can move between a laptop and a phone, choose Hewlett HP Poly Blackwire; if you need the lightest possible all-day headset with twin noise-canceling mics and IT-friendly remote management, choose Logitech H570e.
• Hewlett HP Poly Blackwire — biggest strength: Stereo sound with a 32 Ohm impedance and a full 20 Hz–20 kHz range, plus a 7 ft cable and USB-C/A adapter for plug-and-play across devices.
• Hewlett HP Poly Blackwire — biggest trade-off: It's the heavier of the two at 10.4 ounces, so it's less of a "forget you're wearing it" headset for marathon days.
• Logitech H570e — biggest strength: Just 89 grams with leatherette ear pads and a padded headband, plus dual noise-canceling mics, call/mute LED indicators, and 45% post-consumer recycled plastic in the plastic parts.
• Logitech H570e — biggest trade-off: It's a mono, USB-C wired headset focused on voice calls, so it's not built for immersive stereo listening.
• Buy the Hewlett HP Poly Blackwire if you want one headset that does double duty for calls and richer audio, with a long cable for desk freedom.
• Buy the Logitech H570e if you want the lightest fit and IT-friendly management for large Teams deployments.
The Blackwire 3325 is a stereo, wired on-ear headset that leans into Poly's audio heritage. The spec sheet tells the story: a 32 Ohm impedance and a 20 Hz to 20 kHz frequency response, which is the full audible range. In plain terms, that means the Blackwire is designed to sound good for more than just voice — music, video, and training content all come through with actual left/right separation instead of a single mono channel.
Connectivity is where it earns its keep. You get a 7 ft cable, which is generous for a headset and lets you stand up, reach across a desk, or pace during a call without yanking the plug out. The package includes a USB-C/A adapter, so the same headset works with a USB-C laptop today and a USB-A port tomorrow. It's plug-and-play — no drivers to fiddle with. It's also certified for Microsoft Teams with dedicated controls and a noise-canceling boom mic with echo reduction, so your voice stays clear and the person on the other end isn't hearing your room.
Who should buy it? Anyone who wants a single wired headset for Teams calls who also cares about audio quality — support agents, hybrid workers, students in online classes, or anyone who listens to music between meetings. The stereo drivers and wide frequency range make it a genuinely enjoyable headset, not just a call tool.
Who should skip it? If weight is your number one concern. At 10.4 ounces, the Blackwire is noticeably heavier than the competition here. For an eight-hour shift it's fine, but if you're extremely sensitive to headset pressure, a featherweight option may suit you better.
The Logitech H570e is built around one idea: stay out of your way. It weighs just 89 grams — under a fifth of what the Blackwire weighs — and pairs that with leatherette ear pads and a padded headband. If you wear a headset for a full workday, that low weight is the feature you'll notice most.
It's also clearly designed for shared and managed work environments. Two noise-canceling microphones plus a 30 mm dynamic driver with dynamic EQ and echo cancellation keep your voice intelligible in noisy open offices. LED indicators on the inline controller show call and mute status at a glance — a small thing that matters a lot when you're juggling a queue of calls. There's a dedicated Teams button, and it's certified for Microsoft Teams.
Two details make it stand out for IT buyers. First, Logitech Sync lets admins remotely manage and update headsets, which matters when you're deploying dozens or hundreds of them. Second, sustainability: the plastic parts use at least 45% post-consumer recycled plastic, the packaging is FSC-certified, and the earpads are replaceable to extend the headset's life. Via the Logi Tune app you can adjust sidetone, mic level, and anti-startle protection.
One important caveat from the spec sheet: the style is listed as Mono. So this is a single-earpiece, voice-first headset. It's excellent for calls, but it's not the one for immersive music or stereo video. Connectivity is wired USB-C.
Who should buy it? Call-center and open-office workers, IT teams rolling out headsets at scale, and anyone who prioritizes a barely-there fit and clean manageability. Who should skip it? If you want stereo sound or a headset you can also use with a 3.5 mm phone jack, look at the Blackwire instead.
• Best for audio immersion → Hewlett HP Poly Blackwire. Stereo drivers plus a 20 Hz–20 kHz range versus the H570e's mono voice-first design.
• Best for all-day comfort → Logitech H570e. 89 grams with a padded headband and leatherette pads is a different league of light.
• Best for device flexibility → Hewlett HP Poly Blackwire. The included USB-C/A adapter and 7 ft cable cover more setups.
• Best for IT fleet management → Logitech H570e. Logitech Sync remote management and replaceable earpads suit large rollouts.
• Best for noisy open offices → Logitech H570e. Two noise-canceling mics and LED call/mute status cues are aimed squarely at that environment.
• Best for Teams integration → Tie. Both are certified for Microsoft Teams with dedicated controls.
• Best for sustainability-minded buyers → Logitech H570e. At least 45% post-consumer recycled plastic in the plastic parts and FSC-certified packaging.
• Best for lighter, mono call work → Logitech H570e; best for stereo work and play → Hewlett HP Poly Blackwire.
In my opinion, the Logitech H570e is the smarter pick for most office and call-center users. At 89 grams with dual noise-canceling mics, status LEDs, remote management, and recycled materials, it's purpose-built for the person who lives on calls all day. I'd choose the Hewlett HP Poly Blackwire only if you want one headset that also sounds great for music and video and needs to jump between USB-C and USB-A devices. If you genuinely do both, the Blackwire's stereo audio is worth the extra weight. Otherwise, go light and go Logitech.
Both are certified for Microsoft Teams and include dedicated Teams controls, so either works natively. The H570e adds LED call and mute indicators plus Logitech Sync management, while the Blackwire adds stereo audio and a USB-C/A adapter.
The Logitech H570e is far lighter at 89 grams. The Hewlett HP Poly Blackwire weighs 10.4 ounces, so if weight is your priority the H570e is the clear choice.
No. The H570e is listed as a mono, single-earpiece headset. If you want stereo left/right audio for music and video, the Hewlett HP Poly Blackwire is the better fit.
