My IEM's always seem to develop faulty connections within a couple months of usage and I always lose sound in one channel. I don't know why. I always get IEM's with good build quality.I store them carefully and I don't wrap them around anything or stuff like that. When I use them, they are connected to my phone in my pocket and go under my shirt.
It's getting really annoying to send them back for a replacement every time so how can I prevent this from happening.
