Pretty much whay the title says. Been using the sph9500s for like 8 years now and they are still going strong. Super comfortable and a nice light clamp force. The sound is amazing. Thought I'd upgrade to the sph9600s. I prefer the 9500s much better. Don't get me wrong these are still great headphones. I just felt like the clamping force was tighter and the earpads are thicker and not as comfortable.
