[Q]: Most of the buttons worked when these were new, but never the one that pairs to your device. I was able to get them to pair by starting my music, and using the settings on my phone. Since I bought them last minute before a trip I just went with it. Now, a year later, none of the buttons work. The sound quality and noise cancelling were very nice, but now the volume is stuck at a level only audible in a quiet room... Not really where you need noise cancelling.

[Q]: The number one thing to mention on this case is that the inside area where it will make contact with the back of your phone feels rough like sand paper. I bought two of these and both were the same, so it was not a one off thing. I wound up leaving the plastic wrap cover that came on the phone, on the back to keep the gritty inside back from possibly scratching the phones back. I wish the inside had just been smooth gel because the point of getting the case was to keep the back from getting messed up. Other than that, the cases fit very well and seem like they would provide some protection from a short distanced fall, like if it landed on the corners of the phone.
