The MDR ED 12 (in blue, but I think that the color of the sound is not significantly affected) I use already about 2 years and am very satisfied. I know of no open earphones in this price range, the over brings the bass (especially the deep vibrating) as strong as good closed systems (which gave it in the distant past times when Aiwa). They sound in the entire frequency range for my taste more pleasant and natural as closed earphones. Disadvantage / advantage is that the ambient noise is less attenuated. The portability is good for my ears. My music source is a Sony Xperia Z with the Poweramp app, sometimes the SanDisk Sansa Clip Zip. I hear mostly jazz, but also like classical music, rock, pop or "cross over".
