If you want a lightweight, over-ear headset with 180-degree rotatable ear cups and dynamic audio optimization for long call sessions, choose Plantronics Poly Blackwire 3320; if you need a compact on-ear design with dual noise-canceling microphones and a visible busylight for shared office environments, choose Yealink UH35.
• Plantronics Poly Blackwire 3320: Strength lies in its superior comfort for all-day wear with memory foam padding and a rotating microphone arm; trade-off is the lack of wireless freedom since it relies entirely on a USB-C wired connection. This pick is for professionals who prioritize physical comfort and flexible mic positioning during marathon conference calls.
• Yealink UH35: Strength lies in its dual-microphone array for sharper voice clarity and a built-in red LED busylight that signals availability to colleagues; trade-off is the on-ear fit which may feel less secure or comfortable than an over-ear design for some users. This pick is ideal for busy offices where visual cues matter and a lighter, more portable footprint is required.
The Plantronics Poly Blackwire 3320 is engineered specifically for the professional who spends hours glued to their screen, making it a standout choice for those seeking the best open ear headphones for calls who also value deep immersion without isolation. Its design philosophy centers on "all-day joy," achieved through padded ear cushions and a headband that distributes weight evenly across your skull. Weighing in at just 210 grams, it feels substantial yet manageable, avoiding the pinch points common with cheaper headsets. The ear placement is Over Ear, meaning the cushions surround your ears rather than pressing directly against them, which is a critical distinction for anyone prone to heat buildup or pressure discomfort after two hours of continuous use.
One of the most practical features here is the 180-degree rotatable microphone. In my opinion, this isn't just a gimmick; it is a genuine utility for left-handed users or anyone who needs to adjust the boom arm quickly to avoid knocking it while typing. The headset supports Dynamic EQ, which automatically adjusts sound levels to ensure voices are crisp regardless of volume fluctuations, and includes SoundGuard technology to protect your hearing from sudden spikes. The enclosure combines metal and plastic, giving it a durable feel that suggests it can handle the rigors of daily travel or a busy desk environment. Since it connects via USB-C, it offers plug-and-play simplicity without the anxiety of battery management or charging cables getting tangled.

However, you should skip this model if you strictly require wireless mobility or if you prefer a minimalist aesthetic that sits flush against the side of your head. The over-ear design is excellent for passive noise cancellation by creating a seal, but it might be too bulky for users who need to constantly look up and down or who work in cramped cubicles where the ear cups could snag on monitors. It is also worth noting that while it is certified for Microsoft Teams, it does not include a dedicated busylight feature found on some competing business models. If your workflow demands constant visibility of your status to coworkers, this headset leaves that specific visual communication gap unfilled. Ultimately, this is the tool for the individual contributor who values audio fidelity and ergonomic relief above flashy external indicators.
The Yealink UH35 takes a different approach, focusing heavily on clarity and office etiquette. Designed as a Dual Teams USB-C/A headset, it targets the user who needs to maintain high productivity in a collaborative setting where silence is golden. The defining characteristic here is the dual microphone setup with advanced noise cancellation technology. While many headsets rely on a single boom mic, having two allows the device to better distinguish your voice from background chatter, ensuring that your tone remains consistent even when a printer is humming nearby or a colleague is talking three desks away. This makes it a strong contender for anyone looking for the best bluetooth headset for calls (though note this specific model is wired) in noisy environments where voice isolation is paramount.
Comfort is addressed differently here compared to the Poly. The UH35 uses skin-friendly materials and soft memory foam ear pads, but the form factor is On Ear rather than Over Ear. This means the drivers sit directly on your ears rather than encircling them. The oval shape of the pads helps distribute pressure, and the leather headband adds a touch of premium feel. At 139.5 grams, it is significantly lighter than the Poly, which is a tangible difference if you wear glasses or have a sensitive scalp. The construction uses high-quality plastic reinforced with a metal frame, suggesting a balance between durability and portability. A unique selling point is the highly visible busylight featuring red LEDs; when you are on a call, this light flashes to signal to others that you are unavailable, reducing interruptions in an open-plan office.
This headset is perfect for remote workers or hybrid employees who need to seamlessly integrate with major UC platforms and Yealink IP phones. The inclusion of a carry bag in the package indicates a focus on users who frequently move between home and office spaces. However, the on-ear design might not suit everyone for extended periods. Some users find that sitting directly on the ear cartilage becomes uncomfortable after several hours, especially if they wear thick frames. Additionally, while the passive noise cancellation is effective, the open nature of on-ear designs generally lets in more ambient sound than a fully enclosed over-ear cup. If you work in a very quiet home office, the busylight might be unnecessary, but for a bustling corporate floor, it is an essential tool for managing boundaries.

For me, the deciding factor comes down to the primary use case: for calls, I would choose the Plantronics Poly Blackwire 3320. The ability to rotate the microphone and the over-ear cushioning provides a level of comfort and flexibility that simply cannot be matched by the on-ear design of the Yealink, especially during back-to-back meetings. While the Yealink UH35 is a fantastic piece of hardware with great dual-mic performance and a useful busylight, the physical experience of wearing a headset for eight hours straight favors the Poly's engineering. The Dynamic EQ and SoundGuard features also give me confidence that my audio quality will remain consistent throughout the day. If you prioritize how the headset feels on your head and the reliability of your voice transmission, the Plantronics is the safer, more robust investment.
Yes, the over-ear design of the Blackwire 3320 creates a better physical seal around the ears for passive noise isolation compared to the on-ear Yealink UH35, though both utilize noise control technologies.
While it integrates natively with Yealink IP phones and is certified for Microsoft Teams, it functions as a standard USB-C audio device compatible with most major communication platforms.
The Yealink UH35 is significantly lighter at 139.5 grams and comes with a carry bag, making it easier to transport than the 210-gram Plantronics Blackwire 3320.
Both products include a limited warranty description as stated in their specifications, though the exact duration and terms should be verified on the manufacturer's official documentation.
