Bests & Worsts Reviews from Amazon

Since there are plenty of reviews addressing various aspects of sound quality, I'll just try to help those who can't decide between the Black and Red. I own both Black and Red for a few months now, and I listen to both regularly, about 10 hours a week. I can't tell the difference despite listening to each through one of the best set of headphones. Black is great, and knowing what I know now, I would only buy another black model. I see no reason whatsoever to pay extra for an imperceptible difference.
