How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wireless, single-ear headset you can walk away from your desk with, choose PLT Poly; if you need a wired stereo headset for all-day calls and music at your computer, choose Yealink UH37. That's the short version. The longer version is about how you actually work — and since I get asked about setups for toddlers and little kids more than you'd think (bluetooth earbuds for toddlers, sports earbuds for toddlers, the search for the best volume limiting sleep headphones for toddlers), I'll be blunt up front: neither of these is a child's product. Both are adult, work-grade headsets. The whole point of this comparison is which one fits your workday better, and I'll flag the kid angle where it honestly applies.
• PLT Poly's biggest strength: true wireless freedom — Bluetooth 5.2, a BT700 USB adapter, and up to 50 m / 164 ft of range, plus a 24-hour average battery life. Its biggest trade-off: it's a single-ear design, so you're not getting stereo music or full isolation from both ears.
• Yealink UH37's biggest strength: a wired, stereo, dual-mic headset with 35 mm speakers, dynamic EQ that switches between call and music modes, and dual mute controls. Its biggest trade-off: USB only — you're tethered to your computer or device, no wireless roaming.
• Battery and mobility → PLT Poly. Plug-and-roam, Teams button on the headset, charge stand included.
• Stereo sound and desk-bound focus → Yealink UH37. Two ears covered, music mode, lift-to-mute.
• Pick PLT Poly if you're a hybrid worker bouncing between home, office, and phone calls.
• Pick Yealink UH37 if you live at your desk on back-to-back calls and want a stereo wired setup.
The Voyager 4310 is built around multitasking. It's a single-ear, over-ear headset with an adjustable padded headband, and the whole pitch is that you keep one ear open to the room while you take calls. If you've ever tried to answer a question from someone standing next to you while on a conference call, you know why that matters.
Where it earns its keep is mobility. You connect to a PC or Mac through the included BT700 Bluetooth adapter, or straight to a phone over Bluetooth 5.2. Poly claims up to 50 m / 164 ft of range with that adapter, and the battery is rated at 24 hours average life with a 1.6-hour charge time. That's a full workday and then some, and the included charge stand means it has a home on your desk instead of a tangle of cable.
Who should buy it: hybrid workers who move between rooms, home and office, and who take a mix of PC and mobile calls. Who should skip it: anyone who wants stereo music while working, or who wants a wired connection they never have to think about charging. This is an adult professional tool — not something I'd hand to a toddler.
Yealink UH37: Who It's For
The UH37 is the desk-bound counterpart, and it's unapologetically wired. USB-A connection only, over-ear stereo design, and a focus on call clarity plus music quality during the workday. It uses dual noise-canceling microphones with Yealink's Acoustic Shield technology, which does the same job as Poly's Acoustic Fence in principle — shield the noise, keep the voice.
The audio story is more ambitious here. Professional-grade 35 mm speakers, stereo sound, and dynamic EQ that automatically switches between call mode and music mode. The frequency range is listed as 20 Hz to 10 kHz. In plain terms: clear voice on calls, fuller sound when you're listening to music between meetings. If you like having something playing while you work, that's a real difference from the single-ear Poly.
Comfort and control are clearly priorities. Yealink notes it's 15% lighter than the previous generation, with soft leather ear cushions and an ergonomic design aimed at long conference calls. You get dual mute controls — a mute button and lift-the-mic-to-mute — plus an integrated busylight that shows your working state to people around you. It's compatible with Windows 8/10/XP and macOS, and you can connect and manage two call devices at once and switch between PC and mobile.
Who should buy it: call center staff, support agents, and anyone parked at a desk all day who wants both ears covered and stereo sound. Who should skip it: anyone who needs to walk around while talking, or who wants a wireless setup for mobile calls. Again — this is adult work gear, not a kids' audio product.
• Best for battery life and wireless freedom → PLT Poly. 24-hour average battery, Bluetooth 5.2, and up to 50 m / 164 ft of range.
• Best for stereo sound and music at work → Yealink UH37. 35 mm stereo speakers with dynamic EQ.
• Best for hybrid and mobile calls → PLT Poly. Connects to PC/Mac via the BT700 adapter and to a phone over Bluetooth.
• Best for a fixed desk and long call blocks → Yealink UH37. Wired USB-A, no charging to think about.
• Best for staying aware of your surroundings → PLT Poly. Single-ear design keeps one ear open.
• Best for mute control and visible status → Yealink UH37. Dual mute options plus an integrated busylight.
• Best for Teams-first workflows → PLT Poly. Dedicated Teams button and native Teams experience.
• Best for multi-device switching at one desk → Yealink UH37. Connect and manage two call devices simultaneously.
For most hybrid and mobile workers, I'd buy the PLT Poly Voyager 4310. In my opinion, the combination of 24-hour battery, a charge stand, Bluetooth 5.2, and the huge wireless range makes it the more flexible headset for a workday that moves around — and the dedicated Teams button is a small thing you'll appreciate daily. The Yealink UH37 is the better pick if you're planted at a desk and want stereo sound with music mode and a wired connection you never charge. Neither is a toddler product, and if your actual goal is something like the best volume limiting sleep headphones for toddlers, look at dedicated kids' audio instead — but for adult work calls, these two are the real contenders.
Is the PLT Poly or Yealink UH37 better for working from home and the office?
PLT Poly, in my opinion. Its Bluetooth 5.2 and included BT700 adapter let you connect to a PC or Mac and to a mobile phone, and the up-to-50 m / 164 ft range means you can step away from your desk mid-call.
No. The UH37 is a wired USB headset — USB-A connection only. It's designed to stay tethered to your computer, which is why it has no battery spec and routes everything over the cable.
Yealink UH37. It's a stereo over-ear headset with 35 mm speakers and dynamic EQ that automatically switches between call mode and music mode. The PLT Poly is single-ear, so it's built for calls and awareness, not stereo listening.
I wouldn't recommend it. Both are adult, professional headsets with over-ear designs and adult-oriented features. If you're hunting for bluetooth earbuds for toddlers, sports earbuds for toddlers, or volume limiting headphones for toddlers, these aren't the right category.
