For the prize, these sound amazing! I was extremly happy about my purchase until the headband broke. I only used them normally, with no extreme stretching at all. It is made of fragile plastic. This happened after just one month of usage. I might try to build a custom headband, and keep the cups :) Also, for me, a person with a big head and hair, the headphones sits quite tightly. I have the headband extended to the largest.
