If you want a wired, work-first headset with a boom mic and no charging anxiety, choose PLT Poly Blackwire 5220; if you need a wireless, multi-device headset with long battery life and bigger drivers for gaming and entertainment, choose Acer 2.4GHz.
• PLT Poly Blackwire 5220 biggest strength: Wired reliability with USB-C, USB-A, and 3.5mm options, plus a flexible boom mic and passive noise cancellation built for calls.
• PLT Poly Blackwire 5220 biggest trade-off: It's on-ear and wired, so you're tethered, and there's no battery, Bluetooth, or wireless freedom.
• Acer 2.4GHz biggest strength: Tri-mode wireless (Bluetooth 5.3 + 2.4GHz + wired), 40+ hours of battery, and large 50mm drivers for immersive sound.
• Acer 2.4GHz biggest trade-off: It leans gaming/entertainment, has touch controls that some users dislike for calls, and needs charging.
• Pick PLT Poly Blackwire 5220 if you live on calls, want plug-and-play simplicity, and value a dedicated boom mic.
• Pick Acer 2.4GHz if you want one headset for gaming, PC, and consoles with wireless freedom and long battery life.
The Blackwire 5220 is a workhorse built around one job: clear voice communication. It's a wired headset with a flexible boom mic, so the mic sits right where you need it instead of picking up your voice from across the room. The connectivity story is its real selling point — you get USB-C, a USB-C to USB-A adapter, and a 3.5mm jack in the box, which means it plugs into modern laptops, older USB-A ports, and phones or tablets with a headphone jack. No pairing, no charging, no dropouts.
The design is on-ear with a rounded-tip earpiece shape and passive noise cancellation. Passive cancellation means the physical fit blocks some ambient sound rather than using electronics, which keeps things simple and battery-free. Controls are handled through a remote with buttons, so call control is tactile and predictable. It's also listed as compatible with Microsoft Teams and Zoom, which tells you the target audience: remote workers, office staff, and anyone on back-to-back calls.
Who should buy it? If your day is meetings, softphone calls, and video conferences, this is the sensible pick. The 2-year manufacturer warranty and the included carrying case reinforce the "professional tool" angle. Who should skip it? If you want to walk around while listening, game wirelessly, or need deep bass for movies and music, the wired, on-ear, call-focused design will feel limiting. It's not trying to be a lifestyle headset — it's trying to make you sound good on a call, and that's exactly what it's built for.
The Acer 2.4GHz headset takes the opposite approach: flexibility and freedom. It's a tri-mode headset with Bluetooth 5.3, 2.4GHz wireless, and a wired 3.5mm option, so you can jump between a PC, PS5, PS4, Switch, or a phone depending on how you connect. The 2.4GHz dongle-style connection is the low-latency path favored for gaming, while Bluetooth is the convenient path for phones and everyday listening.
It's an over-ear design with 50mm dynamic drivers and a mix of ABS, aluminum, leather, and plastic in the build. Over-ear cups plus 50mm drivers generally mean a fuller, more immersive sound than a small on-ear call headset, which fits its gaming and entertainment positioning. The battery is rated at up to 40 hours with a 3-hour charge time, so you're not hunting for a cable every day. Noise control here is listed as environmental noise cancellation and sound isolation, and the controls are touch-based rather than buttons.
Who should buy it? Gamers who want one headset across consoles and PC, plus anyone who wants wireless freedom and long battery life for media. Who should skip it? If your priority is crystal-clear voice on business calls, the touch controls and entertainment-first tuning may not suit you as well as a dedicated boom-mic headset. And if you hate managing charge cycles, wired will always be simpler.
• Best for calls and meetings → PLT Poly Blackwire 5220. Flexible boom mic, remote button controls, and Teams/Zoom compatibility make it purpose-built for voice.
• Best for wireless freedom → Acer 2.4GHz. Bluetooth 5.3 plus 2.4GHz plus wired gives you three ways to connect.
• Best for battery life → Acer 2.4GHz. Up to 40 hours of average life with a 3-hour charge — the Blackwire has no battery to worry about at all.
• Best for plug-and-play simplicity → PLT Poly Blackwire 5220. USB-C, USB-A adapter, and 3.5mm in one box means it works almost anywhere without pairing.
• Best for immersive gaming sound → Acer 2.4GHz. Over-ear cups and 50mm dynamic drivers point clearly at gaming and media.
• Best for all-day comfort on long calls → PLT Poly Blackwire 5220. The on-ear, rounded-tip design and lightweight 138g build are aimed at extended wear.
• Best for multi-device households → Acer 2.4GHz. One headset across PS5, PS4, PC, Switch, and phone covers more ground.
• Best for predictable physical controls → PLT Poly Blackwire 5220. Buttons on a remote beat touch controls when you need to mute fast mid-call.
In my opinion, the right pick comes down to what you actually do all day. If you're on calls — Teams, Zoom, softphones — I'd buy the PLT Poly Blackwire 5220. It's the more focused tool: wired reliability, a real boom mic, button controls, and universal connectivity in the box. It just works.
If gaming and wireless freedom matter more, I'd buy the Acer 2.4GHz. The tri-mode connection, 40-hour battery, and 50mm over-ear drivers make it the better all-rounder for play and media. In my view, the Blackwire wins for work; the Acer wins for everything else.
Plug the headset in and set it as your input and output device in your system's sound settings. The PLT Poly Blackwire 5220 connects via USB-C, USB-A, or 3.5mm, while the Acer 2.4GHz can connect through its 2.4GHz wireless, Bluetooth, or a wired 3.5mm jack.
For a wired set, just plug it in. For wireless, put the headset in pairing mode. The Acer 2.4GHz supports Bluetooth 5.3 and 2.4GHz wireless, while the PLT Poly Blackwire 5220 is wired-only with USB-C, USB-A, and 3.5mm options.
Use the 3.5mm jack if your phone has one, or a compatible adapter. Both headsets list a 3.5mm jack, and the Acer 2.4GHz also supports Bluetooth 5.3 for phones without a headphone port.
Record a short clip and play it back, or use your app's mic test. Check that the boom mic on the PLT Poly Blackwire 5220 is positioned near your mouth, and confirm the Acer 2.4GHz is set as the active input device in your software.
