great overall sound, easy to wear



This is for me the best headphone that I will ever need. I use it when I move the lawn, when I travel, and when my musical tastes are not acceptable to my family... It has a great dynamic range, sounds very neutral, packs great bass slam, with clear midrange and highs, in short, a great and very userfriendly set, highly recommendet.
