Mobile warriors are always looking for a good pair of earphones. While I don't use any of the Ipod/Zen/Zune multimedia players, my old, trusty Mp3 player needed an upgrade in sound quality, so I started looking for the most obvious improvement, a brand new pair of earphones. A quick walk down to the local store revealed a brand well known to audiophiles, Sennheiser. The only available set was the MXL51, which I eventually bought. How well does this product perform under everyday use?
