The Blackwire 3320 is a wired, over-ear stereo headset with USB-C connectivity. Its plug-and-play design is intended for straightforward setup, and the headset is certified for Microsoft Teams and Skype for Business. For a call center desk where the computer has USB-C, that combination keeps the setup focused on calls rather than wireless pairing.
Its microphone rotates 180 degrees, so you can position it on either side. The headset also has padded ear cushions and a padded headband, and its listed weight is 210 grams. Those details may appeal if you want a lightweight over-ear design for extended work sessions. The microphone’s noise cancellation and passive noise control are relevant in shared work areas, though the specifications do not quantify how much background noise they reduce.

Choose the Blackwire 3320 if USB-C, stereo audio, and the rotating mic are priorities. Skip it if your work computer requires USB-A and you do not have a suitable way to connect a USB-C headset.
The Yealink 1308134, also called the UH35 Dual Teams, is a wired, over-ear headset with USB-A connectivity. It is certified for Microsoft Teams and designed to work plug-and-play with compatible devices such as a VoIP phone, desktop, or laptop. For an office that already uses USB-A equipment, that connection may be the simplest fit.
Its two noise-canceling microphones are intended to support clear speech, while the stereo earphones provide passive noise cancellation. Dual 35 mm speakers are specified for HD audio. The headset also includes ActiveProtection technology for hearing protection, plus a dedicated Teams button for answering calls with one press. A busylight can signal your status to nearby coworkers, and the included cable is 1.5 meters long.
The product information lists a weight of 7.2 ounces and a lightweight design for all-day office use. Choose Yealink if you want its Teams-specific controls and status light alongside USB-A. If your computer setup calls for USB-C, or a microphone that can be positioned on either side is important, the listed features of the Poly may suit you better.

The connection is worth checking before anything else. A headset with the wrong connector can complicate an otherwise simple setup. After that, consider how calls are handled: Yealink makes its Teams button and busylight explicit, while Poly emphasizes microphone flexibility and Dynamic EQ.
Neither description supports a promise that one will eliminate every office sound or fit every listener. Both have passive noise control, and both are over-ear wired stereo headsets. If you are searching for with mic kids headphones for call center use, these are described as adult communication headsets, not as products specifically designed for children. And if your search is for the best in ear earbuds for call center work, neither is an in-ear option: both use over-ear ear placement.
For a USB-C call center setup, I would choose the Plantronics Poly Blackwire 3320. I prefer its rotating microphone, padded over-ear design, Dynamic EQ, and SoundGuard features for a workday built around calls.
If my desk were set up for USB-A and I relied on the Teams answer button or busylight, I would choose the Yealink instead. My call center recommendation is the Poly when USB-C is the right connection and its mic flexibility is useful.
Choose based first on the connection your computer needs: Poly is USB-C, while Yealink is USB-A. Then weigh Poly’s rotating microphone and Dynamic EQ against Yealink’s dual microphones, Teams button, and busylight.
The Poly description specifies microphone noise cancellation and passive noise control. Yealink specifies two noise-canceling microphones and passive noise cancellation through its stereo earphones; the supplied information does not provide a measured comparison.
It is described as Microsoft Teams Certified and includes a dedicated Teams button for answering calls. It also has USB-A plug-and-play connectivity and a busylight for signaling status.
Both are described as lightweight, over-ear headsets intended for workplace use. Poly lists padded ear cushions and a padded headband, while Yealink describes its design as lightweight for all-day office use; fit and comfort are personal.
