**update** not long after writing this review I was contacted by the seller and a new pair were sent to me. Comfortable and so far the waterproof aspect of the shoe is working. Mal im Blackout (CoD) absprang, dachte ich WOW, der Sprachchat ist endlich sauber zu verstehen, auch die Mitten sind deutlicher wahr zu nehmen. - Contents: Two Wireless Earphones, One Charging Base, 3 Pair Ear Caps S / M / L, 1 USB Cable, User Manual, Extended Warranty card for 12+6 Months Warranty, Lifetime Technical Support Objectively: not original for open back HD598SE (which I own) or Sennheiser HD598SR (both essentially the same). I wore them around the house for a whole day, since they were quite stiff (compared to my running shoes), and then I played for nearly two hours the next day. I sent them back, but found happiness with the Rio. I run a lot of these have just been a joy. So disappointed and a big waste of my effort. I really do wish I could have used it.
