This time I got a rather unusual headset, which is designed exclusively for UC systems. What is UC? It’s very simple: it translates as “Unified communications” and represents the integration of real-time services. These include telephony, video conferencing, call control, and so on. The most understandable mode of work is the communication of employees of a company with a client using a special headset in a noisy place, for example, in a call center.
It is worth recalling that Poly is a new brand emerging from the merger of Polycom (a manufacturer of audio and video conferencing systems and infrastructure) and Plantronics (a manufacturer of headsets for various areas of communication).
So, Poly has released a new headset called Blackwire 8225. This device has noise cancellation technology, and in two directions: both the UC system specialist does not hear the ambient noise, and the client receives an accurate voice transmission without extraneous sounds.
The thing is extremely specific for the average user, but from time to time it is worth writing such materials for general acquaintance with such gadgets. The cost is about 20,000 rubles.
The device is a classic wired PC headset: two headphones, a thin headband, a microphone and a long USB cable. Sold in black only. I think that the question of choosing a color is not worth it, since this is a purely corporate story, where there is no sense in color self-identification.
It is worth noting the quality of the materials here separately, since it is assumed that the user will sit in them for at least a working day, periodically taking off and putting the headset on his head. And for this it is important that the body has a large resource.
Despite the abundance of plastic (and it is necessary here to reduce the weight of the structure), the materials in this gadget are at a high level. It seems that you are holding an expensive headset for centuries!
The design of the device is such that the cups can be rotated 180 degrees. In addition, they can be moved relative to the vertical by about 20 degrees in one direction and the other. There is a black spacer between the cups and their holders. It is necessary to soften the impact of the cups on the holders when you quickly put on the headset. During the rotation of the head, the cups move, and the gasket prevents the plastic from touching the plastic: there are no extraneous sounds, less friction – longer service life.
Each cup has decorative round inserts with concentric circles on the outside. Some design trick to dilute a rather boring look.
The ear pads are most likely made of leatherette. The manufacturer says nothing about this. Although natural leather would be a little more appropriate, because it “breathes”, which means that the ears will sweat less. There is a soft material inside the ear cushions.
A microphone is attached to the right earcup. It has a swivel mechanism and can rotate 300 degrees. This is necessary if you need the cable and microphone to be on the left.
The length of the microphone “stem” is 110 mm. At the end, there are metal meshes on the right and left. The “stem” is malleable and can take the position that the user specifies.
The headband is made of plastic. The inner part is soft, made of the same material as the ear cushions. There is something very soft inside, probably foam rubber.
The length of the headband is adjustable on each side near the cups by 30 mm. Therefore, the headphones will fit any head size, even if you use a special headdress or wear a national one.
The length of the rather thick red cable is 2150 mm. This is enough to connect the device to a computer remote from humans. More is better than less, in this case 🙂
A headset control unit is installed on a cable length of 600 mm. It is a relatively flat rectangular box made of black plastic. Here the materials are already both to the touch and seemingly cheap, as in headsets “all over 50”.
There are mechanical buttons on the block: making a call, adjusting the volume and mute the microphone. On the side there is a noise reduction mode switch: off, medium and high ANC.
A very important parameter, since it is assumed that the headset will be used as a working tool. And it should be such that it does not cause discomfort even after more than 5 hours.
And here I can say that the developers did everything possible so that the user almost did not feel the device on his head and ears. The ear cushions are very soft, the pressure is unobtrusive, as if the cups have springs that simultaneously pull the headphones to the center and prevent the ear cushions from snuggling too tightly.
In addition, the material allows you to cut off unnecessary noise (passive noise cancellation), but no pressure is created on the eardrum.
The only remark, which I still don’t understand how to get rid of, is the severity of the cable. It pulls down the lightweight construction of the headset. Therefore, it is necessary to come up with some kind of holder. Otherwise, the cable will periodically be pulled downward, thereby creating a load on the area near one ear.
Total: the most comfortable wearing for a long time.
There are two noise reduction technologies here. One technology helps the specialist (cuts off external noises), the other – to the interlocutor (he does not hear extraneous noises from the specialist).
The ANC setting can be adjusted on the remote control: turn on to maximum, middle position, and off. I can’t say that ANC works better here than on popular large headphones like BOSE or Sony, but noises typical for PCs, office equipment, fans are easily eliminated! You can still hear the voices of the people around you.
However, when I first heard the sound recording through the headset, only one phrase was spinning in my head: “This is a fiasco, bro.” The impression that I went back to my youthful past, when I recorded my thoughts on a PC using a penny microphone with 22 kHz quality: wild compression, narrow frequency range.
However, this is how noise cancellation works in the headset, simply destroying all extraneous sounds. The voice itself is legible, and the interlocutor perfectly understands what you are saying.
Here’s an example of a Poly microphone recording with simulated call center noise. Yes, the background is picked up, but it does not interfere with the speech in any way.
Here is another example of a recording that simulates the sounds of an airport or train station. In this case, the background sound is even louder, but in reality I could not even hear myself.
Just in case, here is an example of voice recording on an AKG Lyra microphone with imitation of office sounds. Yes, cleanliness and clarity are at their best, but the background noise does not stand up to any criticism – it is very loud, the interlocutor is not heard well.

From observations: sounds coming closer to the microphone “choke” harder. Therefore, knowing this nuance, place the microphone so that it “looks” towards the maximum noise.
Auto-adjusting the voice volume level works fine. You can either speak in a whisper or switch to higher tones – the level will be approximately the same, without distortion, even in the case of a shout.
“SoundGuard DIGITAL technology: sound level limiting to protect hearing from sounds exceeding 118 dBA. G616-based protection against sudden loud noises ensures that noise is limited to a level not exceeding 102 dB SPL; the time-weighted average function limits the average daily noise exposure to 80 to 85 dBA (enabled by Plantronics Hub software). “
If we are talking about the sound quality in headphones, then you have a pretty decent headset. The level of devices for 10,000 – 15,000 rubles. With deep bass, great mids and clear highs. I was pleasantly surprised.
For the first time I tested a professional headset designed to operate the device in UC systems. In addition, Poly can also be used in regular business conversations via Skype or Zoom. It is worth understanding here if you need such aggressive noise cancellation. If you are broadcasting from an adit or sitting in a combine, then yes! 🙂
If Poly Blackwire 8225 is compared with some computer headsets or microphones, the latter will sound much better, but they will not be able to “remove” noise in real time.
The cost of the device, to put it mildly, is rather big – about 20,000 rubles.
In general, the gadget is important and necessary for professional use.
