Poly Voyager (218473-02)

The Poly Voyager 4310 UC has one of the best boom mics we've tested, perfect for work calls. But battery life is terrible and music sounds flat. Worth it only if call clarity is your top priority.

Call quality is where this thing shines. The dual-mic setup with Acoustic Fence tech does a great job cutting background noise, and our data puts it near the top of the charts for mic performance. ANC is solid too, around the 74th percentile, which helps on the listening side. Connectivity is decent with Bluetooth 5.2 and the included BT700 adapter giving you up to 50 meters of range. But the audio drivers are tuned for voices, not bass drops. Music sounds thin and flat, and the 20th percentile sound score backs that up. Battery life is the real pain point, one of the worst we've seen in this category, so expect to charge it often.

Stacked against the Sony ULT WEAR or Sennheiser MOMENTUM 4, the Voyager 4310 UC loses badly on music and battery. Those are lifestyle headphones that happen to take calls. The JBL Tune 670NC and TOZO HT3 are cheaper and sound better for media, but their mics can't touch this Poly. The Bose QuietComfort 884367-1100 offers better ANC and comfort, but again, the boom mic here is the differentiator. If your priority is being heard clearly on calls, none of these competitors beat the Voyager. If your priority is enjoying audio, all of them do.

Pricing is all over the map depending on where you shop. In Europe, you'll see EUR 120 to EUR 138 across four listings, so it pays to compare vendors. The best deal we spotted is at the lower end of that range, so check DE, ES, FR, and IT listings before you buy. For a work-focused headset with a top-tier mic, that's reasonable. But the weak battery and mediocre build make it feel less premium than the price suggests. If calls are your main gig, it earns its keep. If you want an all-rounder, your money goes further elsewhere.

The Poly Voyager 4310 UC is a single-ear Bluetooth headset built for work calls, not music. It's light at 122g, has a boom mic with Acoustic Fence noise canceling, and comes with a BT700 USB-C adapter for solid PC connectivity. The mic is the star here, landing in the 96th percentile of our database. Callers will hear you clearly, even with chaos around you.

But this is a specialist tool. Sound quality for music sits in the 20th percentile, and battery life is rough at the 7th percentile. If you want one headset for calls, music, and everything else, this isn't it. If you live on Teams calls all day and need to hear your surroundings, it's a focused little workhorse.

Skip this if you want one headset for music, movies, and calls. The sound quality is a weak spot, and the battery life will frustrate you daily. Also skip it if you need stereo audio or immersive sound, the single-ear design just can't deliver that. If you're a commuter or casual listener, look at the Sony ULT WEAR or Sennheiser MOMENTUM 4 instead.

Buy this if you're a hybrid worker who spends hours on Teams or Zoom calls and needs a reliable, comfortable single-ear headset with a killer mic. It's built for multitasking, letting you hear your surroundings while you talk. Just don't expect it to double as your music headphones, and keep a charger handy because the battery won't last long.
