The rubber case of each headphone is coming away from the headphones themselves, noticed the other day and they have gotten worse and worse. Was expecting a lot with bose’s reputation. I use my headphones a bit at work and to workout but this seems like a factory glueing issue. Great quality otherwise and great sound
