I needed a replacement cable for my QC3 headphones. I was disappointed when told by a Bose service rep over the phone that Bose no longer carry that part. I was advised by the Bose Rep to buy one elsewhere online e.g. Amazon.
So I did. I ordered one through Amazon. It arrives and I unpack it, plug the 2.5mm plug end into my Bose QC3 headphones and the 3.5mm plug end into my MacBookPro running GarageBand. Problem is that now Left and Right channels seem have been reversed. I could just wear my headphones the other way round I guess but its super annoying. Ideas?
