Why don't you disclose that they are not covered by the guarantee because they are not certified for use in 2022? Could you explain how you plan to fix the problem and whether or not the promise still stands. Problem addressed, headphones accepted, money refunded. They said there was a problem with the delivery. There are benefits to it: It aches to wear these for long periods of time, but they perform their job and raise no problems about the headphones themselves (albeit the front of the case is little damaged, despite they were packaged). A call can be heard well by both parties, and the music is of high quality. I thought they wouldn't hurt while I wore them, so that's a con. I tried them on for length of time before purchasing, and found that after 30 minutes of wear, discomfort sets in. Millimeter adjustments are unnecessary after they are properly fitted. After reading that replacement overlays were available, I contacted customer service to see if I could purchase some (I currently use small ones, but they don't fit well and are too hard to remove), but they informed me that the serial number indicated that the headphones were intended for use in the United Arab Emirates and were not certified until 2022.
