How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a secure wireless headset for children to use in supervised, noise-sensitive settings, choose Plantronics Poly Savi 7320-M; if you need a simple wired headset for kids who only ever join calls at a shared desk, choose PLT Poly. That is the honest split here, and it is the whole reason this comparison matters once you start shopping for noise canceling open ear headphones for children rather than for yourself.
• Plantronics Poly Savi 7320-M — biggest strength: true wireless DECT freedom, up to 580ft/180m line-of-sight range and up to 13 hours of talk time, with stereo over-ear cups and a noise-canceling microphone.
• Plantronics Poly Savi 7320-M — biggest trade-off: it is a serious enterprise device built for adult professional use, with no Bluetooth by design, so it is more headset than a child needs for casual listening.
• PLT Poly — biggest strength: plug-in-and-go simplicity with USB-A and USB-C on the same cable, plus built-in hold and call answer buttons that even a young user can manage.
• PLT Poly — biggest trade-off: it is wired only, single-ear mono, and its stated frequency range is just 200 Hz – 8,000 Hz, which is voice-tuned rather than music-friendly.
• Who each pick is for: Plantronics Poly Savi 7320-M for supervised wireless use where privacy and range matter; PLT Poly for a fixed desk setup where one ear stays open.
This is the headset that does the heavy lifting. It pairs DECT wireless with up to 580ft/180m of line-of-sight range, so the wearer is not leashed to the desk. The ear placement is over-ear with full cups, the driver is dynamic, impedance is 32 ohm, and audio latency is stated at 15 milliseconds — low enough that lip-sync feels natural during a live call or a lesson.
Security is the headline. It is designed to meet DECT Security Step C, the highest level from the DECT Forum, reinforced with FIPS 140-2 listed features and 256-bit AES encryption. Poly positions it for financial, medical, government and contact center environments, and it explicitly avoids Bluetooth, which many of those settings ban. If the reason you are shopping is that your child joins a supervised session in a clinic, a tutoring center or a locked-down school network, that design logic is exactly the point.
The microphone uses Poly Acoustic Fence noise-canceling technology and the system meets the Microsoft Teams Open Office specification, so a voice does not have to compete with a room full of background chatter. Battery runs up to 13 hours of talk time with a 2-hour charge. It is Teams certified, works with a wide range of Poly desk phones and over 800 desk phones industry-wide, and Poly Hub adds softphone management. Weight is listed at 16 ounces.
Who should buy it: an adult managing a child's supervised headset, or an older student in an environment where call privacy, range and a clean mic are non-negotiable. Who should skip it: anyone who wants a cheap, casual pair for music and games — this is a professional communication tool, and it is priced and built like one. Check the current price on Amazon before deciding, because this tier of hardware moves around.
The PLT Poly is the opposite philosophy, and that is not an insult. It is a mono, over-the-head single-ear headset with an angular earpiece shape around the ear. One ear stays open, which is genuinely useful — a kid can hear a parent call their name while still being on a call, and nothing is muffled or sealed off.
Connectivity is the selling point. USB-A and USB-C connectors sit right on the cable, so it works no matter which port the computer has. The inline control carries clear hold and call answer buttons, and it delivers a native Microsoft Teams experience straight from that controller. It is built for call center staff working from home or shifting to cloud communications, and it plays nicely with platforms like Avaya, Genesys and Cisco.
The audio is voice-first: a dynamic driver covering 200 Hz – 8,000 Hz. That range captures speech cleanly and nothing more. Passive noise cancellation means the earcup physically blocks some sound rather than actively cancelling it. There is also acoustic protection that manages safe volume — a real consideration when a young user is on calls for long stretches. Weight is 180 g, it is wired USB with Bluetooth listed as the wireless technology, and it carries a 2-year manufacturer warranty.
Who should buy it: a household or classroom with a fixed desk, where a child needs one obvious button to answer and one ear free. Who should skip it: anyone who wants wireless movement, stereo sound, or a headset that doubles as a music pair.
Side-by-Side: Which Should You Choose?
• Best for wireless range and freedom → Plantronics Poly Savi 7320-M (up to 580ft/180m line-of-sight versus a tethered cable).
• Best for security and privacy → Plantronics Poly Savi 7320-M (DECT Security Step C, FIPS 140-2 listed features, 256-bit AES encryption, no Bluetooth).
• Best for microphone clarity in a noisy room → Plantronics Poly Savi 7320-M (noise-canceling mic with Poly Acoustic Fence, built to the Teams Open Office spec).
• Best for plug-and-play simplicity → PLT Poly (USB-A and USB-C on the same cable, no pairing, no charging).
• Best for keeping one ear open → PLT Poly (single-ear mono design, which is also the safer choice for a child you need to stay in earshot).
• Best for hearing safety on long calls → PLT Poly (acoustic protection that manages safe volume).
• Best for stereo sound → Plantronics Poly Savi 7320-M (stereo over-ear cups versus mono voice audio).
If I were buying one of these for a child to use in a supervised, call-heavy setting, I would buy the Plantronics Poly Savi 7320-M. The combination of stereo over-ear cups, a noise-canceling microphone with Acoustic Fence, 13 hours of talk time and genuinely long DECT range makes it the more complete tool, and the encryption story is reassuring when a minor is on the line. I would only switch to the PLT Poly if the setup is a fixed desk, the child is young enough that a cable and one big answer button is a feature rather than a limitation, and keeping one ear open matters more than sound quality. In my opinion, the wired unit is the better "first headset," and the Savi is the better headset, full stop.
Only the Plantronics Poly Savi 7320-M is wireless — it uses DECT with up to 580ft/180m line-of-sight range and up to 13 hours of talk time. The PLT Poly is a wired USB headset, so if movement matters, the Savi is the only real option.
Not exactly. The Savi 7320-M is over-ear with a noise-canceling microphone and active noise control, so it seals rather than opens the ear. The PLT Poly keeps one ear open but only offers passive noise cancellation. If you specifically want an open-ear fit, neither is a perfect match.
The PLT Poly. It plugs in with USB-A or USB-C, needs no pairing or charging, and has dedicated hold and call answer buttons on the inline control. The Savi 7320-M is the more capable device but asks more of the user.
They sit in different tiers — one is an enterprise wireless system, the other a wired call center headset — so the gap is real. Since I cannot quote figures here, check the current price on Amazon for both before you commit.
