If you want secure wireless freedom for webinar calls, choose Plantronics Poly Savi 7310; if you need wired stereo listening with adjustable noise cancellation, choose PLT POLY Blackwire 8225. The Savi’s long line-of-sight range and up-to-13-hour talk time suit people who move around during the workday. The Blackwire is a more desk-centered choice, with a boom microphone, stereo sound and three ANC settings.
Plantronics Poly Savi 7310 vs PLT POLY Blackwire 8225 at a Glance
• Plantronics Poly Savi 7310: Its standout is DECT wireless range of up to 580 feet line of sight, plus up to 13 hours of talk time. The trade-off is a single-ear design rather than stereo listening.
• PLT POLY Blackwire 8225: Its strengths are wired USB-A/USB-C connectivity, stereo sound and hybrid active noise cancellation with three settings. The trade-off is that a cable ties it to the device.
• Choose the Savi 7310 if you need to move away from your desk, support desk-phone workflows, or prioritize call privacy and DECT security.
• Choose the Blackwire 8225 if you mainly work at a computer and want both ears covered, on-headset call controls and adjustable noise cancellation.
• For webinar hosts who value mobility, the Savi fits better; for people who stay seated and want stereo audio, the Blackwire has the clearer use case.
The Plantronics Poly Savi 7310 is a single-ear wireless headset system built around DECT connectivity. Its maximum line-of-sight range is up to 580 feet, and the listed talk time is up to 13 hours. Those figures make it a practical option for someone who needs to walk around during a long workday without staying tethered to a computer or desk phone.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
Its noise-canceling microphone uses Poly Acoustic Fence technology to help keep nearby conversations from interfering with the caller’s experience. The product is also designed around DECT Security Step C and 256-bit AES encryption. That emphasis makes it a particularly relevant fit for workplaces handling sensitive calls, including financial, medical and government settings.
I’d consider the Savi for webinar work when I need to stand, move around or switch among supported phone and softphone workflows while speaking. Its single-ear fit leaves the other ear uncovered, which may suit someone who wants awareness of the room. I’d skip it if I specifically want stereo playback, active noise cancellation for listening, or a wired connection to a computer. The 13-hour figure is talk time, not a stated listening-time figure, so it shouldn’t be treated as a direct comparison with music playback.
The PLT POLY Blackwire 8225 is a corded headset with USB-A and USB-C connectivity. Its on-ear design covers both ears, and its audio specification spans 20 Hz to 20 kHz. In practical terms, it is aimed at someone who stays close to a connected computer and wants stereo listening for calls and other audio, rather than a wireless headset for walking around.
For calls, it has a flexible boom microphone with noise-canceling technology and Acoustic Fence. Hybrid active noise cancellation offers three settings, so the wearer can adjust how much surrounding sound is reduced. The controls include call answer and end, mute and volume, while the Microsoft Teams version includes a dedicated Teams button. The listed headset weight is 186 grams.
The Blackwire is a strong fit for a fixed webinar station in a shared or noisy office, especially if the wearer wants both ears covered and the ability to change ANC settings. Its main limitation is the cord: it doesn’t offer the Savi’s wireless range or listed talk-time battery figure. Choose something else if you need to roam during calls, or if DECT security and wireless desk-phone flexibility are central requirements.

The phrase “open ear earbuds for webinars” often points shoppers toward something lightweight that lets them hear the room. Neither of these models is an open-ear earbud: the Savi is single-ear, while the Blackwire is an on-ear stereo headset. If hearing surrounding conversation is a priority, the Savi’s one-ear design is the closer match, but it is still a headset rather than an ear-clip product.
Likewise, neither is literally an ear-clip headphone or an open-ear model. Someone searching for the “best voice assistant ear clip headphones for webinars” should check the wearing style and connection needs carefully rather than assuming either product has ear clips or a voice-assistant feature. For a rechargeable open-ear headset, the Savi’s wireless design is closer to that broad wireless use case, but its listed features do not describe an open-ear or ear-clip fit.
My Verdict
For webinars where you may walk away from your desk, the Savi 7310 has the advantage: it offers DECT wireless connectivity, up to 580 feet of line-of-sight range and up to 13 hours of talk time. For a fixed computer setup, the Blackwire 8225 offers stereo listening, USB-A/USB-C connectivity and three ANC settings.
The Blackwire 8225 lists hybrid active noise cancellation with three settings for adjusting listening noise reduction. The Savi 7310 lists a noise-canceling microphone with Acoustic Fence technology, which is intended to help keep nearby conversations from affecting calls. These features address different parts of the listening and speaking experience.
No. The Savi 7310 is described as a single-ear headset, so one ear remains uncovered. The Blackwire 8225 is an on-ear stereo headset. Neither product is described as an open-ear earbud or an ear-clip headphone.
The Blackwire 8225 may suit someone who wants stereo listening and adjustable ANC, with three settings to adapt to the environment. The Savi 7310 may suit someone focused on voice calls, microphone noise reduction and wireless mobility. Consider whether your main need is reducing sound you hear or managing what the microphone picks up.
