First, these headphones do NOT have 'kicking bass'. What they do have is balanced sound allowing for clear notes and sound separation to be heard across the spectrum. The sound will represent the originally mastered. However, if a song is mastered with an incredibly heavy thump, these headphones can deliver with their 50mm drivers. Vocals are amazing. The nearly all metal and leather construction is exceptional. The swivel is spin a can off the ear is well executed. I like that it came with a short and long cord and either can be plugged into either can.
