I´ve bought one pair of Bose soundlink AE II around ear and the firt pair broke within 2months, the sound in the left headphone wanished almost completley. I got a new pair and the held for about a yera and then the samething happend. I got a brand new ones from the Bose waranty but after loading them and plugged them in the same thing happend. Now I have to return these brand new ones and ask for yet another new pair. Is this a common production error on these headphones? I bought these pair because I wanted quality, but now I´m not sure if I made the right desision.
