Some pros: I really liked the sound. It transmits the entire spectrum well - low and high. Noise reduction works enough to sit in the office in relative silence and not be distracted by neighboring conversations. Has cons: BUT! I bought them for another purpose, namely as a good wireless headset for video calls. Headphones are not suitable for these purposes. When for the 5th time they told me that they could hear me disgustingly, I finally realized that I had overpaid several times. The comments are different - "you seem to be talking from a can", "you are very far away", "you are almost inaudible", etc. This was repeated on different devices, in different programs, on different Internet - everywhere the same thing. I thought (hoped) that it was in the settings, but no, nothing helps.
