If you want a wired USB-C headset for PC with stereo audio and SoundGuard, choose Plantronics Poly Blackwire 3320; if you need wireless freedom and the flexibility to move between a computer and phone, choose Logitech Zone 305. For a desk-based PC setup, I’d lean toward the Blackwire; for calls that follow you around the room, the Zone 305 is the more practical fit.
• Plantronics Poly Blackwire 3320: wired USB-C connection, hi-fi stereo audio, and SoundGuard; the trade-off is being tethered to the computer.
• Logitech Zone 305: Bluetooth, connection to two devices, and up to 30 meters of stated range; the trade-off is that it needs charging.
• For long, stationary PC calls: choose the Blackwire 3320 for its straightforward wired setup.
• For moving between a PC and a phone: choose the Zone 305 for its wireless multipoint connection.
• For either pick: both have padded headbands and ear cushions, but they differ in connection style and wearing position.
The Blackwire 3320 is a wired, over-ear headset with a USB-C connection. Its plug-and-play design makes it a straightforward choice for someone who wants to connect a headset to a compatible PC without relying on Bluetooth or a battery. The product information specifies hi-fi stereo audio, a dynamic driver, and a 20 Hz–20,000 Hz frequency range. It also supports Dynamic EQ, which adjusts sound levels, and SoundGuard, which is designed to protect hearing.
For calls, its microphone has noise cancellation and can rotate 180 degrees, so it can be positioned on either side. The headset is certified for Microsoft Teams and Skype for Business. That combination makes it a sensible pick for a desk where meetings, calls, and PC audio are the main jobs.

The Zone 305 is an on-ear Bluetooth headset built around workplace calls. It has two noise-canceling microphones on a flip-to-mute boom, with noise-suppression processing intended to help capture the speaker’s voice. Its 30 mm dynamic drivers are tuned for calls and other audio. Logitech also describes options in Logi Tune for adjusting sidetone, microphone level, and EQ.
Its strongest practical advantage is freedom of movement. It can stay connected to two devices, such as a PC and smartphone, and its stated wireless range is up to 30 meters. Battery life is listed as up to 20 hours of listening or 16 hours of talk time; a five-minute quick charge is stated to provide up to one hour of talk time. At 122 g, with a padded headband and earcups, it is designed to be lightweight for extended work sessions.
That makes the Zone 305 a good fit for someone who takes calls across devices or doesn’t want a cable at the desk. Its trade-offs are equally clear: it needs charging, has no headphone jack, and uses an on-ear design rather than the Blackwire’s over-ear fit. It also does not provide the Blackwire’s stated hi-fi stereo positioning or SoundGuard feature. If you want a wired PC headset with those specific features, I’d look at the Plantronics instead.
• Best for a wired PC setup → Plantronics Poly Blackwire 3320. USB-C and plug-and-play operation keep the connection simple, with no battery to recharge.
• Best for moving around during calls → Logitech Zone 305. Bluetooth lets you leave the desk, with a stated range of up to 30 meters.
• Best for switching between a computer and phone → Logitech Zone 305. Its multipoint connection supports two devices.
• Best for over-ear coverage → Plantronics Poly Blackwire 3320. Its listed ear placement is over-ear; the Zone 305 is on-ear.
• Best for a longer stated listening run between charges → Logitech Zone 305. It lists up to 20 hours of listening and 16 hours of talk time, but those figures depend on keeping the headset charged.
• Best for a quick wired connection to compatible PC equipment → Plantronics Poly Blackwire 3320. Its USB-C plug-and-play design avoids Bluetooth pairing.
• Best for a flip-to-mute boom and two noise-canceling microphones → Logitech Zone 305. The microphone boom also provides a physical way to mute.
• Best for hi-fi stereo audio and SoundGuard → Plantronics Poly Blackwire 3320. Those features are explicitly listed for the Blackwire, rather than the Zone 305.
Neither headset is an all-purpose audio solution for every listener. The Blackwire’s stereo specification may make it more appealing for general PC listening, but it is still a communication headset, not a product described as a dedicated gaming model. If you’re searching for hifi stereo gaming headphones for pc, consider whether a call-focused headset’s connection and comfort matter more to you than gaming-specific features; those are not detailed for either model.
Likewise, neither one is an in-ear product. Someone searching for the best volume limiting in ear earbuds for pc or sleep headphones for pc is looking for a different form factor and use case. The Blackwire is over-ear, and the Zone 305 is on-ear, so I wouldn’t choose either as an in-ear or sleep-headphone option.
I’d buy the Plantronics Poly Blackwire 3320 for my own stationary PC setup. Its USB-C wired connection, over-ear fit, hi-fi stereo audio, and SoundGuard make a focused package for desk calls and everyday PC listening. The Logitech Zone 305 is the better choice if wireless movement, two-device connectivity, and battery life matter more. My pick for a mostly desk-based PC is the Blackwire, but I’d choose the Zone 305 for a workday that moves between rooms or devices.
For a fixed PC desk, the Blackwire 3320 offers a direct USB-C connection and is certified for Microsoft Teams and Skype for Business. The Zone 305 is the more flexible option if you want to move around or connect to a second device.
Yes. It connects wirelessly over Bluetooth and lists up to 20 hours of listening time or 16 hours of talk time per full charge. A five-minute quick charge is stated to provide up to one hour of talk time.
The feature descriptions are different, so they don’t support a simple direct ranking. The Blackwire 3320 lists microphone noise cancellation and passive noise control; the Zone 305 has two noise-canceling microphones and voice-processing noise suppression. Neither data sheet specifies active noise cancellation for the listener.
That depends on which features you will use. The Blackwire gives you a wired USB-C connection and SoundGuard, while the Zone 305 adds Bluetooth, two-device connectivity, and battery-powered mobility.
