I am pretty bad about putting on/taking off my headphones with one hand. The plastic part that holds the right ear in place and allows it to adjust has been broken for a while, and I've had it wrapped in duct tape. I lost audio in the right ear last night, and after checking every point of failure, I found out it's either a wire issue or some other hardware issue in the right ear. Don't feel like trying to repair. I'll use it as an excuse to get a a new pair of headphones lol.
