One channel is clearly quieter than the other. Could this be because of a dirty filter? I am about ready to send them back to etymotics. They are still under warrenty. But only for a short amount of time longer. I will change filters later today.

I tried on different sources too.

fixed. But the filter looked 100% clean. It was the culprit however.
