• PLT Poly's biggest strength: Three-level Advanced Digital Hybrid ANC (high, low, off) plus Poly Acoustic Fence multi-microphone tech that keeps your voice clear on calls. It's a communications tool first.
• PLT Poly's biggest trade-off: It's a headset with a boom mic, not a pure music headphone — and its 19 hours of talk time trails the Space One's battery.
• Soundcore Anker Space One's biggest strength: Adaptive ANC that auto-calibrates and claims up to 98% noise reduction, with 40 hours of ANC playtime and LDAC Hi-Res audio for music.
• Soundcore Anker Space One's biggest trade-off: No boom mic and no wired jack — it's wireless-only and tuned for listening, not for being heard on a work call.
• Pick PLT Poly if you live on Teams or Zoom calls and want control over how much noise cancelling you get.
• Pick Soundcore Anker Space One if you want to disappear into music on a train, plane or noisy café for hours.
The Voyager Focus 2 UC is designed around one job: making you sound professional on calls while cutting the noise around you. Its Advanced Digital Hybrid ANC gives you three settings — high, low and off — so you can dial the cancellation to match a quiet home office or a busy room. That adjustability is the standout feature here, and it's rare to see it framed as a personal preference rather than a single on/off switch.
The microphone side is where this headset earns its keep. Poly Acoustic Fence technology uses multiple microphones to isolate your voice so callers hear you, not your surroundings. There's also Dynamic Mute Alert, which tells you if you're speaking while muted — a small feature that saves a lot of embarrassing dead air. With up to 19 hours of talk time and a lightweight headband with a sling and plush cushions, it's built to sit on your head through a full workday.
Connectivity is flexible in the way office gear needs to be. You get the included BT700 USB-A adapter for a computer plus Bluetooth 5.1 for a phone, so you can move between a laptop and mobile without re-pairing headaches. It's over-ear, plastic-bodied and black, with a 32-ohm dynamic driver covering 20 Hz to 20,000 Hz.
Soundcore Anker Space One: Who It's For
The Space One is a listening headphone, full stop — and it's aggressive about blocking noise. Its upgraded ANC structure is tuned to cut mid- to high-frequency sound with what Soundcore describes as 2X stronger voice reduction, and the adaptive system detects external sounds and sound leakage, auto-calibrating to keep performance steady even if the headphones aren't seated perfectly on your ears. Soundcore states up to 98% noise reduction under lab conditions, which is the kind of figure you want when a train carriage or café is your office.
Battery is the headline number. You get 40 hours of playtime with ANC on, and 55 hours with it off — enough that charging becomes an afterthought on a trip. Audio is handled by 40mm customized dynamic drivers with LDAC support for Hi-Res wireless listening, which Soundcore says delivers roughly 3X more detail than standard Bluetooth codecs. Bluetooth 5 is on board with a 10-meter range, and everything is controlled through the Soundcore app rather than physical buttons.
The design is over-ear with round earpieces in black plastic, and it ships with a protective case that Soundcore says fits its full over-ear range. Note the trade-offs: there's no headphone jack, so it's wireless-only, and there's no boom mic — this is not a headset for conference calls. Who should buy it? Anyone who wants serious noise blocking, long battery and better-than-average wireless audio for music, podcasts and travel.
Side-by-Side: Which Should You Choose?
• Best for work calls and clear voice pickup → PLT Poly. Poly Acoustic Fence and the boom mic are purpose-built for being understood on a call.
• Best for raw noise blocking → Soundcore Anker Space One. Adaptive ANC with a claimed 98% reduction is the more aggressive system.
• Best for adjustable noise control → PLT Poly. High, low and off lets you match cancellation to your room.
• Best for Hi-Res music → Soundcore Anker Space One. LDAC and 40mm drivers are aimed squarely at listeners.
• Best for multi-device flexibility → PLT Poly. The BT700 USB-A adapter plus Bluetooth 5.1 covers PC, Mac and mobile.
• Best for wired use → PLT Poly (via USB-A). The Space One has no jack at all.
• Best for travel and commuting → Soundcore Anker Space One. The included case and long ANC battery suit life on the move.
In my opinion, the right pick depends entirely on whether you're buying for your voice or for your ears. If your day is meetings — Teams, Zoom, calls back to back — I'd buy the PLT Poly Voyager Focus 2 UC. The adjustable ANC, Acoustic Fence mic tech and multi-device connectivity are exactly what a home-office worker needs, and the mute alert is a genuinely useful touch.
But if you want headphones to escape into music and silence out the world, I'd choose the Soundcore Anker Space One. The adaptive ANC, 40-hour ANC battery and LDAC audio make it the stronger personal-listening tool. Two different jobs, two different winners.
how to active noise cancelling headphones work
ANC headphones use microphones to sample the noise around you, then generate sound waves that cancel it out before it reaches your ears. The Space One takes this further with adaptive ANC that detects external sounds and sound leakage, auto-calibrating to keep reduction steady — Soundcore states up to 98% reduction under lab conditions. The PLT Poly uses Advanced Digital Hybrid ANC you can set to high, low or off.
how to activate noise cancelling headphones
On most models you toggle ANC with a button or an app. The Soundcore Anker Space One is controlled through the Soundcore app, where you manage its adaptive noise cancelling. The PLT Poly Voyager Focus 2 UC lets you switch between high, low and off ANC directly, so you can choose how much cancellation you want at any moment.
how to activate noise cancelling jbl headphones
That's a different brand outside this comparison, but the pattern is similar: JBL models typically use an on-ear button or the companion app. For the two headphones here, the Space One runs through the Soundcore app, and the PLT Poly uses its own on-board ANC level controls. Always check your specific model's manual, since button layouts vary.

Again, Sony is a separate brand, and its headphones usually rely on a physical ANC button or the Sony app. Neither headphone in this comparison is a Sony. If you're choosing between the PLT Poly and the Space One instead, remember the Poly gives you three ANC levels while the Space One leans on adaptive, app-controlled cancellation.
