If you want a simple on-ear headset with a 3.5 mm connection for studying, choose PLT HP; if you need stereo sound, a boom microphone, and USB-C/A connectivity, choose Hewlett HP Poly Blackwire. For study sessions that include calls or online meetings, I’d lean toward the Hewlett model because its dedicated Teams controls and noise-canceling microphone are specific, useful tools. The PLT option is the simpler wired pick, with touch controls and active noise cancellation listed among its features.
• PLT HP’s biggest strength: On-ear design, 3.5 mm jack, touch controls, and active noise cancellation; its trade-off is that the provided details do not specify a boom microphone or dedicated meeting controls.
• Hewlett HP Poly Blackwire’s biggest strength: Stereo wired audio, a noise-canceling boom microphone, echo reduction, and a 7-foot cable; its trade-off is that it requires a wired connection.
• Choose PLT HP if you want a straightforward headset with a 3.5 mm connection and active noise cancellation listed.
• Choose Hewlett HP Poly Blackwire if you expect frequent calls, use Microsoft Teams, or want the flexibility of a USB-C/A adapter and 3.5 mm connection.
The PLT HP is an on-ear, wired headset with a 3.5 mm jack. That gives it a simple connection option for compatible devices, without relying on a wireless connection. Its listed frequency range is 20 Hz to 20,000 Hz, and it has a dynamic driver. Those are useful details if you plan to switch between spoken lessons, videos, and music while studying. They describe the headset’s audio specifications, though they don’t establish how it will sound to every listener or with every device.
Its listed controls include touch control, and active noise cancellation is named in the product details. For a student who wants a wired headset with controls on the headset and a noise-control feature, that combination may be appealing. The design is on-ear, with fabric, foam, plastic, and metal listed among its materials. The listed weight is 0.22 kg. Those details can help you picture the build, but they don’t specify a custom fit, battery operation, or how comfortable it will feel over a long study session.

I’d consider the PLT HP for someone who prefers a 3.5 mm connection and doesn’t need the specific meeting features described for the Hewlett model. It may also suit a buyer looking for a simple headset for study audio, videos, and other everyday listening. Who should skip it: skip this pick if you specifically need a noise-canceling boom microphone, echo reduction, or dedicated Microsoft Teams controls; those details are listed for the Hewlett HP Poly Blackwire, not the PLT HP.
The Hewlett HP Poly Blackwire 3325 is a wired, on-ear stereo headset. It connects through USB-C and includes a USB-C/A adapter, with a 3.5 mm mini-phone connection also listed. That variety gives it more connection options than the PLT model’s listed 3.5 mm jack. Its cable is 7 feet long, which can offer more room to shift position during a call or study session while staying connected. It is still a wired headset, so the cable is part of the everyday setup.
For studying that includes online classes or group calls, the microphone details are a meaningful distinction. This model has a boom microphone with noise-canceling technology and echo reduction, and the product information says it is designed to help transmit clear speech. It also has dedicated Microsoft Teams controls and Teams certification. If Teams is part of your routine, those controls are more relevant than a general-purpose audio feature: they are intended to support meeting use. The headset’s listed frequency range is 20 Hz to 20 kHz, and its impedance is 32 ohms.
The Hewlett model is a practical choice for someone who expects to talk as well as listen: attending lessons, speaking in meetings, or joining study groups. Stereo audio is listed, making it a fit for people who prefer sound through both sides of an on-ear headset. The data describes it as plug-and-play with USB devices, though compatibility still depends on the device and connection being used. Who should skip it: skip this pick if you specifically want a wireless headset; this model is wired, and no wireless connection is listed.
• Best for a listed noise-canceling boom microphone → Hewlett HP Poly Blackwire. Its microphone also lists echo reduction, a useful distinction if speaking clearly is central to your study setup.
• Best for dedicated Microsoft Teams controls → Hewlett HP Poly Blackwire. The PLT details do not list meeting controls or Teams certification.
• Best for a 7-foot cable → Hewlett HP Poly Blackwire. The cable length is specified, so you can account for that extra reach when arranging a desk or study space.
• Best for a straightforward 3.5 mm connection → PLT HP. Its listed connection is a 3.5 mm jack, with no USB adapter detail in the provided information.
• Best for USB-C and USB-A connection options → Hewlett HP Poly Blackwire. It includes a USB-C/A adapter, in addition to the listed 3.5 mm connection.
• Best for touch controls and listed active noise cancellation → PLT HP. Those features appear in its details, while the Hewlett sheet emphasizes meeting controls and microphone noise cancellation.
• Best for stereo listening with a microphone described for calls → Hewlett HP Poly Blackwire. It combines stereo audio with a boom mic and echo reduction.
• Best fit for simple study listening without specified meeting needs → PLT HP. Its 3.5 mm connection and audio range may be enough if calls and Teams controls are not priorities.
Before choosing, check which connection your study device supports. A 3.5 mm jack is the PLT HP’s listed connection; the Hewlett model lists USB-C, a USB-C/A adapter, and a 3.5 mm mini-phone connection. Having an adapter included can matter if you want the Hewlett headset to connect to a device with a different port, but the right setup depends on your computer, tablet, or phone.
Think about whether your study routine is mostly listening or includes regular speaking. The PLT details list active noise cancellation, but they don’t specify a microphone. Hewlett’s product information explicitly describes a boom microphone with noise cancellation and echo reduction. That makes the difference especially important for online classes, presentations, or group discussions. Microphone noise cancellation and active noise cancellation are not interchangeable descriptions: one refers to the microphone, while the other appears as a headset feature in the PLT details.
Also consider how you move around your study space. Both products are wired, but the Hewlett cable is specified as 7 feet long; no cable length is given for the PLT. Neither sheet provides a stated wireless option, battery life, or waterproof rating. So if your priorities are wireless use, long battery sessions, or protection from water, these specifications do not establish either headset as the right choice. A search for the best hifi stereo in ear earbuds for studying or the best ipx7 waterproof wireless headphones for studying points to a different style of product than these wired, on-ear headsets.
I’d choose the Hewlett HP Poly Blackwire for studying if my routine includes online classes or calls. Its boom microphone, echo reduction, Teams controls, stereo audio, and several listed connection options make it the more clearly equipped choice for listening and speaking. I’d pick the PLT HP instead when I wanted a simpler 3.5 mm headset with touch controls and active noise cancellation listed. For a shopper searching for with mic wireless earbuds for studying, neither is wireless based on the supplied details, so I would not treat either as a confirmed match for that need.
