Summary: I don't recommend buying these if you want headphones that last for any length of time. They do have great sound, however.
Pros: -Excellent range -After the initial burn-in, had good bass -Huge, which I like -Very comfortable
Cons: Died 5 months after purchase with no real reason. During the middle of work, the right side just stopped working. Very irritating. I did use these every single day for 8-10 hours a day, but I'm very disappointed in the lifespan, regardless.
Summary: Had good sound up until about 2-or-so months ago. Now just today the right ear has completely stopped working. I record professional audio in my home studio, and these were my backup headphones, now I am just out of luck apparently..
Pros: Had good sound up until about 2-or-so months ago. Comfortable for brief use, not prolonged. (Rather heavy) Cuff inserts are applicable.
Cons: Used it once and it stopped working. Heavy Leather cuffs came with them almost off already. Were just barely glued on.. Re-sizing locks were lacking, slipped down when I wore them.
