3-4 months, something like that. The right earphone is so quiet that I can hardly hear it and the left one has also deteriorated in quality.

Now I might as well have a cheap pair that don't work properly, why bother spending £50 on earphones (the first pair that cost me more that about £10) when they don't last.

There was no real explanation for this either, I was always very careful with them.

Is this just something that happens, or do I have a right to be annoyed?
