At this point only a small response after 25 months of permanent use: Great sound, rich bass (if desired so strong that the ear cups vibrate), good fit in the ear. I used these headphones about 6-10 times a week and have it otherwise permanently crumpled in my pocket transported. After 25 months of continuous use of the sound now has failed on the right ear. This is such a product in the lower price class more than "okay". There are 4 stars. I probably order again.
