This is my second pair of Rondos and I have the same issue, they stopped working. I had hope that they were an issue of my first pair but it´s the same issue with the replacement. Only used like 10 times and the problem happened again. I´m very dissapointing with Bose, because I though that they were an very good brand but with the sunglasses they are a bad choice.
