I bought two pairs of these headphones a few years ago and they have been great. They were also a bit cheaper in price. I wore both pairs alternately for about 3 years. Then, since they were both worn out, I got a new job and bought a new pair. That was in September 2020. It's April and the new pair is already worn out. I put in good insoles for Christmas, but the upper part of the shoe is separating from the sole. As a result, they are no longer waterproof. They open every time I squat or bend
