Tried unpacked and then I was still quite negative surprise from the headphones ..
JBL advertises to give the best sound and to make a "new experience" with the sound, but Nope ..
Ups and downs are okay though, but the basses are not even nearly as good as my other 20 headphones.
That made me then to move the headphones back to send.
For people might listen and the only Rock, Pop etc. these headphones work fine, but not if you like to listen to electronic music (techno, trance, ...).
