Without repeating whats on the video just let me simply say if youre wanting active noise cancelling headphones, "THESE ARE THE ONES"! La uso para hacer wall ball shots en casa ya que no han abierto gimnasios. Upon opening the package it contained two stainless steel pods, two freshness covers, seals, measure scoop/tamp and what appears to be two seal replacements(pic1). I liked the look when on was surprised that it held on so well. They are Sooooo comfortable. If you do snap one of these joints, you can repair this yourself. If the water pools or does not pass through cleanly, then the screen material is clogged with detergent, fabric softener or water repellent. If youve been reading reviews, youve probably read all this elsewhere. Thus far, Ive experienced no leaning, sagging, or other indication of a structural issue. We took good care of these headphones, never dropped them or exposed them to moisture.
