I havnt had them 6 months and havnt had the opportunity to do anything real with them other than around the house and town and they have already begun to fall apart. As you can see in the picture I sent the right strap is a bit larger then the left. So now they stick out farther and are not as comfortable for some people. Very loud, very clear, beats the Mackie thump series by a long shot. Needles are awesome. That?s amazing came with all special food flavor inside my wife were happy and I?m to the part that holds your foot down. Its like a tire loosing air. I had a dongle on my keys, lost it twice. I went up from a 7.
