If you want wireless freedom and a dedicated touchscreen call-control base for work, choose Yealink DECT Headset WH66; if you need a straightforward wired headset with USB and 3.5 mm connections, choose Hewlett HP Poly Blackwire.
The Yealink is the more flexible desk setup; the Blackwire is the simpler plug-in option.
For calls, meetings, and everyday computer use, the deciding question is whether you value moving around or prefer a cable-connected headset.
Yealink DECT Headset WH66 vs Hewlett HP Poly Blackwire at a Glance
• Yealink DECT Headset WH66 strength: DECT wireless operation, a 14-hour stated battery life, and a 4-inch touchscreen base. Trade-off: it needs charging and is a single-sided headset.
• Choose Yealink if you want to move around during calls and manage them from a desk base.
• Choose Blackwire if you prefer a direct wired connection and stereo audio.
The WH66 is a wireless, single-sided DECT headset built around a desk base with a 4-inch capacitive color touchscreen. That screen is a notable part of the setup: rather than relying only on headset controls, you can use the base to manage calls. Yealink also lists Acoustic Shield Technology and a 2.5 mm connection.
For work, I’d consider it if you spend much of the day on calls and want room to stand or shift away from your desk without taking the headset off. Its stated battery life is 14 hours, with a listed charge time of 2.5 hours. The headset also supports hands-free calling, which suits a desk routine where you want call controls within reach but not necessarily on the headset itself.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.

The Blackwire 3325 is a wired, stereo headset with a 7-foot cable, USB-C connectivity, a USB-A adapter, and a 3.5 mm mini-phone connection. It also has dedicated Microsoft Teams controls. That makes it a practical candidate for someone who wants to connect to a compatible device and get on with work without adding a wireless base to the desk.
Its boom microphone is described as noise-canceling, with echo reduction. For a workday built around calls and meetings, that microphone setup is more relevant than broad promises about sound: the boom sits by the mouth, while the headset’s stereo design also serves listening tasks beyond voice calls. The listed audio frequency range is 20 Hz to 20 kHz.
The cable is the main compromise. Seven feet gives some room to shift around, but it is not the same as being untethered. Choose the Blackwire if you stay close to a computer or phone, want stereo playback, or prefer wired connectivity. Skip it if walking around during calls is a priority.
• Best for moving around during calls → Yealink DECT Headset WH66. Its DECT connection is wireless; the Blackwire’s 7-foot cable keeps it tethered.
• Best for a touchscreen call-control base → Yealink DECT Headset WH66. Its 4-inch capacitive color screen gives call management a dedicated place on the desk.
• Best for a wired, plug-in setup → Hewlett HP Poly Blackwire. It supports USB-C, includes a USB-A adapter, and has a 3.5 mm connection.
• Best for stereo audio → Hewlett HP Poly Blackwire. It is specified as a stereo headset, while the WH66 is single-sided.
• Best for a stated battery-life figure → Yealink DECT Headset WH66. Yealink lists 14 hours of battery life and a 2.5-hour charge time; the Blackwire is wired.
• Best for dedicated Microsoft Teams controls → Hewlett HP Poly Blackwire. Its feature set includes Teams controls and certification.
• Best for a boom microphone with stated noise cancellation and echo reduction → Hewlett HP Poly Blackwire. Those microphone features are specifically listed for the Blackwire.
• Best for a desk-centered wireless setup → Yealink DECT Headset WH66. The base and wireless headset make more sense if you want call controls on the desk and freedom to move.
A few common search terms need a reality check here. Neither product is described as a pair of Bluetooth earbuds for work: the WH66 is a DECT headset, and the Blackwire is wired. Neither sheet lists a transparency mode, so I wouldn’t call either one the best transparency mode headphone for work. And while either may be used for audio at a computer, the supplied details don’t establish either as the best gaming headphones for work; the Blackwire’s stereo design may appeal for listening, while the WH66 is more clearly oriented toward wireless desk calls.
My Verdict
I would choose the Yealink DECT Headset WH66 for work if my day involved frequent calls and I wanted to move around without a cable. Its DECT connection, 14-hour stated battery life, and touchscreen base make it the more distinctive desk-call setup.
I’d pick the Hewlett HP Poly Blackwire instead for a simpler wired routine, stereo listening, and dedicated Teams controls. My personal preference is the Yealink when mobility matters; the Blackwire is the sensible alternative when staying connected by cable is no drawback.
The WH66 is described as a DECT wireless headset. The product details also list Bluetooth version 4.2, but the core wireless connection specified for operation is DECT. It is not described as Bluetooth earbuds.
The Blackwire is specifically listed as Microsoft Teams certified and includes dedicated Teams controls. The WH66 is identified as a Teams model and is described as working with common unified communications platforms, but the listed details do not specify dedicated Teams controls on the headset.
The WH66 lists Acoustic Shield Technology and active noise cancellation. The Blackwire lists a noise-canceling boom microphone with echo reduction. These features address different parts of the calling experience, so the specifications alone don’t establish one as universally better.
Think about the setup you’ll use every day: wireless mobility and a touchscreen base with the WH66, or wired stereo sound and USB/3.5 mm connections with the Blackwire. To compare what each currently costs, check the current price on Amazon.
