Query: Surprising Sound

These sound much better than I expected for the sale price. I'm no audiophile but these meet and exceed and satisfy my aural needs. Note that I got the HD201S (has an 'S' on the end) so maybe some updates to the product since some of the reviews I read on Amazon, one I noticed is that the cans swivel slightly now so that they contour to the ear better. Despite the low sensitivity I was impressed with the sound I got from my iPhone with these. They also sound good to me powered by a computer. High volume hurts my ears so I don't listen very loud and I could still hear plenty of definition across the frequency range.
