There was also a cut in one of the sandals rubber. I turn off the receiver pack between sets and am getting well over three, three hour sets. I thought maybe it was low powered because I put a bad battery in it, but thats not the case either. I just received it yesterday and only played 3 games on it today, but man was I ahead of where I was with my last paddle. Beautiful look but super disappointed in the quality. UPDATE - Had these almost 1 month and I noticed by accident that when I picked them up I could hear a small rattle from the right hand cup mainly (no music playing through them). In spite of this, the shoes are very comfortable, would fit nicely with people with a wider foot I think if u order a half size or one size up. For me, it would be the ATH-ANC700BT if I was using it primarily in the office and the Bose if I was a frequent flyer. I cant think of when I would use that, but at least the option is there.
