Looking for great sounding InEars for iPod shuffle 4G, I have now just these Sennheiser. Very good sound, the treble and midrange but unfortunately too much bass the beginning still ok acts but quickly annoying and overused hearing. Less Bass and therefore balanced and they were for the 50 absolute P / L Hammer. The bent by 90 ° jack connector makes the iPod Shuffle very unwieldy. The enclosed plastic shell is a good addition. Shame about the bass, now I have to look any further.
