I bought a Shure SE215 with universal cable last year from Store DJ. Within the warranty period the up volume button stopped working. It became fixed and wouldn't depress.
I contacted in December Store DJ who said that they would have to send it away to the manufacturer to be checked. This will take a few weeks. With the Xmas New Year break it would take 4 weeks so I decided to leave it till now.
Is this acceptable? They can easily tell it's faulty when I bring it to a retail store so I thought not? Should be easy to replace there and then.
I think that's a reasonable time-frame to repair the product. They may want to get it professionally inspected too. How do you prove whether it's a manufacturing defect or you broke it through wear and tear/dropping it/water damage/pressing it excessively hard etc.
