Hi, I own a set of etymotic er6i headphones. I bought them about 3 years ago. They have an issue now of connectivity- when I move and they jump around, the music goes on and off as if the cable is torn. My questions:
1. Is it fixable?
2. I was offered a replacement set by etymotic for 60$. Should I get it?
3. I want to have a high quality canal noise cancellation headphones. Any alternatives?

Thanks.
