Why don't you disclose that they aren't certified for use in 2022, and hence not covered by the warranty, as a precaution, I ask the vendor. Is the guarantee still valid, and if so, how do you plan on using it to fix the problem? The problem has been fixed, the headphones have been returned, and the money has been given back. They said there was a mistake with the delivery. Reasons to be optimistic: They're functional, the headphones themselves don't raise any red flags (albeit the case on the front side is slightly worn, despite they came packaged), but they hurt after prolonged use. The music sounds great, and the call quality is quite high. Opposing factors of a variety: Even though I knew better, I wore them nevertheless because. I tried them on for length of time before purchasing, and found that after 30 minutes of wear, discomfort sets in. Millimeter adjustments are useless once they are properly attached. I called customer care to see if I could obtain replacement overlays (I had read that they fixed the problem; I use small ones, but they don't fit and are too hard), but they identified the headphones as being from the United Arab Emirates and saying that they weren't certified until 2022.
