Hey, got my 2nd pair of the E2c, now this pair seems to have a problem, the left phone doesnt work, the right one works fine. Anyone ever experienced this before?

So I'm considering purchasing one and I want to get opinions from people that own one on what they think about it. I'm particuarly interested in the battery life, how well it works with WMP10, sound quality, how well the touch pad works, and if it plays WMA lossless.

My left ear is deaf, so therefore when I am wearing headphones, I cannot hear anything in the left stereo channel, I have devised several methods to allow me to hear everything, read: something that will mix the right and left channels together and output the same mix to the left and right...

If I was to rip a track fresh from a retail cd, and use the following settings, will the mono file sound just as good as the stereo file?. Using lame: 1."Very High Quality q=0" preset, 320kbps, stereo. 2. "Very High Quality q=0" preset, 160kbps, mono. Will the file sound the same...
