This review is from: Sennheiser CX 300 II Precision Noise Isolating Earphones - Black (Electronics)
As several other customers have said, the L-shaped jack is a major design flaw. Mine stopped working after 2 months of very carefu use, i.e. no pulling of cords, not putting mp3 player in pockets and so on. They look brand new, nothing visible from outside, but no sound is produced. Great shame for a good brand. Sound is good for news, not great for music. Not recommended at all, buy something else.
