Poly Voyager 218478-01

The Poly Voyager 4320 UC is a call-quality monster with a 96th percentile mic and 24-hour battery life at a reasonable $120 price. It's comfortable enough for all-day wear and includes the BT700 adapter for rock-solid PC connections. But there's no ANC, sound quality is average, and build feels cheap. Buy it for calls, not for music or commuting.

The headline number here is the microphone. 96th percentile in our database means this thing outclasses nearly every consumer headset we've tested for voice pickup. The Acoustic Fence tech uses two mics on the boom to create a pickup zone around your mouth and aggressively filter out everything else. Keyboard clatter, coffee shop chatter, a dog barking in the next room, it all gets pushed way down. Callers hear you, not your life. That's the whole point of this product and it delivers.

Battery life is solid at 24 hours of wireless talk time, which puts it in the 69th percentile. Not a record breaker, but enough for three full workdays before you need to plug in. The Bluetooth 5.2 connection with the included BT700 USB-C adapter gives you up to 50 meters of range, which is genuinely useful if you pace during calls or need to grab something from the printer. Sound quality for music is middle of the pack at the 54th percentile. It's fine for background listening and YouTube, but the drivers are tuned for voice clarity, not bass response. If you want thumping low end, look elsewhere.

Against the Sony ULT WEAR, the Poly wins on mic quality and loses on everything else. The Sony has real ANC, better sound, and a more premium build. But the Sony's mic is mediocre for calls, and that's the Poly's entire reason to exist. If you're on calls all day, the Poly is the better tool. If you want one headset for everything including music and travel, the Sony is more versatile.

The Sennheiser MOMENTUM 4 is in a different league for sound quality and build, but it costs significantly more and its call mic is not in the same class as the Poly's boom setup. The JBL Tune 670NC and TOZO HT3 are budget options that undercut the Poly on price and offer ANC, but their mics are nowhere close. The Beyerdynamic Aventho is a niche audiophile pick that doesn't compete on call features at all. For pure voice work, none of these touch the Poly. For everything else, most of them beat it.

At $120 USD, this is a very reasonable price for a certified UC headset with a boom mic that performs this well. Comparable Jabra Evolve or Yealink models with similar call quality often run $150 to $250. The included BT700 adapter alone typically sells for around $40 to $50 on its own, so you're getting solid value in the box. European pricing sits around 124 to 131 EUR, which tracks similarly.

The value equation depends entirely on your use case. If you're buying this for calls, it's a steal. If you're buying it for music and casual listening, you're paying for a mic you won't use and getting sound quality that a $60 pair of consumer headphones would match. The CAD pricing at $209 feels steep compared to the US and UK numbers, so Canadian buyers might want to shop around or wait for a sale.

The Poly Voyager 4320 UC is not trying to be your everything headset. It's a work tool first, a music gadget second, and it's completely unapologetic about that. Poly (formerly Plantronics) built this for the hybrid worker who spends half the day on Teams calls and the other half trying to ignore the chaos of an open-plan office or a noisy kitchen. The pitch is simple: a lightweight stereo headset with a boom mic that makes you sound like you're in a quiet room even when you're not.

What makes this interesting is the focus. While Sony and Sennheiser are cramming in adaptive ANC and spatial audio, Poly went all-in on call quality and all-day comfort. The dual-mic Acoustic Fence setup sits in the 96th percentile for microphone performance in our database. That's not just good, that's best-in-class territory. If you've ever been on a call with someone whose keyboard sounds like a hailstorm, you know why this matters.

But here's the trade-off. This is a passive noise isolation headset, not an active noise cancelling one. The ANC score lands in the 32nd percentile, which is polite database-speak for 'there basically isn't any.' The pads block some ambient noise, but you're not getting the silence bubble you'd get from a Sony ULT WEAR or a Bose. For calls, the mic does the heavy lifting. For your own focus time, you'll need to manage expectations.

Skip this if you want one headset for everything. The lack of ANC makes it a poor choice for commuting, air travel, or working in a loud office where you need to block out noise for your own focus. The sound quality is also just average, so music lovers will be underwhelmed. If you're buying a headset primarily for entertainment with occasional calls, get a Sony ULT WEAR or Sennheiser MOMENTUM 4 instead.

Also skip it if you care about build quality. The 34th percentile build score means this thing feels plasticky and won't survive being tossed in a bag without a case. If you're rough on gear or travel frequently, a Jabra Evolve2 or a more ruggedly built headset will hold up better over time.

If you spend more than two hours a day on calls and you work in a noisy environment, buy this. The mic quality alone justifies the price. Your colleagues will notice the difference immediately, and you'll stop apologizing for background noise. The comfort is genuinely excellent too, so long days with the headset on won't leave your ears feeling crushed.

If you're a hybrid worker who also wants to use the same headset for music, commuting, or focus time in a loud office, this is not the one. The lack of ANC is a real limitation, and the sound quality won't impress anyone. You'd be better off with a Sony ULT WEAR or spending more on a Jabra Evolve2 with ANC. The Poly Voyager 4320 UC is a specialist, and it's a great specialist, but it's not a generalist.
