Hello There, I tried these headphones as an alternative to Sony ZX600. Sonically no significant difference can be seen that Sony has in my opinion a little more dynamic. Real bass but you do not find in both. Why now the deduction? Although the idea of the folding mechanism when JBL's class, but not implemented. The turning of the shells is far too heavy. Thus, they are not good to the ear and it constantly has the impression cancel shell when turning. Also, it squeaks loudly. Also, we should thereby remove the cable, which would annoy me personally. JBL should definitely revise the mechanism. Compared to Sony, he sits much tighter on his head. The ironing pad is better than the Sony. I decided to get a better wearing comfort for the Sony and the JBL goes back. Greetings
