Came damaged, missing hardware and the screws that came with it didn’t even fit in the holes. Only problem is that it is a little larger than expected. I even loosened the strap and still had this problem. These are literally the best quality earphones that Ive owned to date and I paid less for them than for any other decent headphones Ive used in production work. Im returning these, and definitely would not recommend. I wish I could scream through this message that’s how mad I am. The tread on the bottom is also a big positive. Smart. The song I tested between these headphones was Ocean Man by Ween, because of the formidable range in pitch. Bei diesem paar gibts kein quietschen!
