High-quality headphones with a good microphone! Due to their construction, they embrace and isolate the ear, resulting in passive noise cancellation (you don't hear other sounds in the area as loudly). After extensive use, they show no signs of wear. If you hear your own voice when speaking for the first time you connect them, you will need to download their software to disable this option. Unfortunately, I couldn't do it simply from Windows. Besides, you need the software to download updates. I give them one less star because they are not the cheapest headphones in their category and because sometimes when my computer locks and then I unlock it, the headphones don't work and I have to close and reopen them even though they haven't lost connection. Of course, this could be a general problem with USB headphones, but also some incompatibility with the collaboration program I use.
