I bought them for video calls at work so I wouldn't have to constantly switch my (average) Razer Barracuda X from my PS to the office. They do the job, but they are very lightweight and have nonexistent clamping force on the ears, causing me to feel like they will fall off with the slightest movement. Perhaps they fit better on rounder heads.
At maximum volume, the sound is somewhat low, but I can be heard clearly by others. I thought the length of the cable would be convenient, but in the end, I would prefer it to be longer.
Overall, for 30 euros for non-wireless headphones, I believe there are better options available.

I have been using these headphones for over a month for teleconferences.
They are excellent in sound isolation, which was the main reason I bought them.
No complaints from colleagues anymore about how I sound!
The sound quality for music is satisfactory, but their design is not so comfortable for long hours of use.

Excellent choice. I got them for meetings via Teams when I'm at the office. The sound isolation on the microphone is fantastic. I can only hear myself and none of my colleagues, even if they are two meters away in the office. Also, due to the fact that I listen to music almost constantly, they unexpectedly have great sound even though they are not made for such use. They are lightweight, with a long cable, and do not strain the ear. How long they will last remains to be seen, but so far they are definitely value for money.

Extremely good headphones for the purpose they are intended. Very good sound and noise cancellation, they make you hear very clearly, they are lightweight, good controller, value for money!

I struggled quite a bit to find the ideal headphones for teams and skype. The famous "good" brands of 60 euros only caused me problems such as interference, lag, and echo, both for me and my conversation partners. Until I reached out to the company's IT department. They recommended these specific ones, which they have been supplying in dozens for the past 2-3 years and they work exceptionally well without any issues. Truly, the sound is excellent, both for me and my conversation partners. The isolation could be better, but they are very lightweight and comfortable after several hours of conference calls. Truly value for money.

Very comfortable and nice sound. The only issue is that they only have a USB connection. The c3225 have a 3.5mm Jack connection as well, so I would buy those if I were to purchase again.

In the positives, the perfect noise cancellation. You can hear clearly. It doesn't have interruptions. In the negatives, it doesn't have good sound isolation in the ears, resulting in maximum volume and sometimes not hearing clearly in a noisy environment. The cushion or headband is not good. For the 30€ they cost, I think it's OK.

I have lost count of how many we have at work and none of them have broken, they isolate external sound to an incredible degree, they are lightweight and durable.

They work perfectly with Microsoft Teams and only capture my voice while isolating all external noises. I would like the mute button to turn off the headset microphone instead of indicating on Teams that I am muted. My previous Logitech headsets did this
