Summary: Do not get this headset unless you are considering amplifying it. It sounds bad without an amp.
My Experience: These cans sound nice when amplified/ bad when not amped. Good highs, okay lows, overall pretty good sound. They are closed and will block out the outside world.
Pros: Suppress outside noise very well, Sounds good, Mic quality is very good
Cons: Bass is lacking, sound bad without amplification, non serviceable cable
