I have to have the bass set to around half as these will give ur ear drums a serious pounding.
I never heard anything like it; not just bass but highs and mids, too.
Also, punchy bass was a bit of headache after a while - they prefer that rolling bass at the frequencies pointed out above.
Expect to be moved in more ways than you can imagine.
5 out of 5 stars 4.
the headband has a nice felt on the outside, rubber on the inside.
