I could hear others speaking and listen music clearly. The sizing is off, I ordered a size smaller than my last pair but these somehow feel bigger than my last. EDIT: The part that comes in contact with your foot is incredibly slippery, even when dry. Concludo con un "Finalmente un case che abbia una ricarica con il type C" (cavo incluso nella confezione) . If 3 damp towels are placed one in front of the other, they are touching and would not dry properly. Excellent sound quality, and great noise cancelling. Sound Quality: Sound is very good and almost crisp as in some wired headphones. If it is same price, I will choose DT770 PRO, but its price is double. I purchased this product because I live in Fairfield California and the water is upward of 225 TDS. In addition to the tools provided, I had to use a drill bit and wrench to stabilize the pegs that attach both halves.
