I think I was expecting the outside sounds to be amplified through the earbuds, but it was only not as muffled without any music playing. I glued them with industrial glue and now they are my around the house pair. I didnt know it when he introduced them that I was suffering from overexposure and that I had become, or maybe always was, ehs (electrically hyper-sensitive). Beide sind sehr nüchtern abgestimmt. It was a little odd to install/hang but once it was up I just used some sticky putty to secure it even more to the wall and it?s perfect! It slides freely through the clip. We?ve had NO problem with the toe portion rolling under risking a fall. If you?re looking to lose weight and dedicated to losing weight, going to the gym and eating right then this is a huge boost and can really help you out meeting your goals and most importantly looking great! This upgraded/improved version is a really good fit - the top and bottom are very well fitted and are not gonna come off any time soon. Sometime louder.
