Plus the nonslip bottom started coming apart. You can hear people clearly when on the phone but there was NO noise cancelling. Bought this so I can ride and study at the same time. I tested the GPS with another phone and a 3 mile run was just as accurate as the phone. The part folds up nicely when not in use. Was able to firmly hang on wall with some planning and use of anchors and screws we had around the house. This is beautiful! sounded "muddy" (no highs/no lows). It took a little bit of time to get started on the first box, but after that it’s a breeze. I did not hear any hiss sound when ANC is on.
