Why don't you mention that they aren't certified for use in 2022 and so not covered by the warranty, I ask the seller. Can you still use the assurance, and what steps will you take to implement it? The problem has been fixed, the headphones have been returned, and the money has been refunded. Some sort of delivery issue, they claimed. The pluses include: While there are no issues with the headphones themselves (while the front of the case is slightly worn, the headphones themselves were packaged), wearing them for extended periods of time can be painful. Sound quality and call clarity are both high. Con: I didn't think wearing them hurt, and I was right. I tried them on for length of time before purchasing, and found that after 30 minutes of wear, discomfort sets in. If you put them on properly, a few millimeters won't make a difference. I contacted customer service to inquire about purchasing replacement overlays (I'd read that they resolve this problem; currently, I'm making do with small ones, but they don't fit well and are too hard to use), 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.
