Title: Well built, but just don't fit
Review: I bought these earphones because of their reputation for quality and the ability to stay in your ears during exercise. Sennheiser delivers on the quality side; the MX75s appear well built and solidly assembled. The sound is above average, too. But these things just won't go into my ears. The cheap phones that came with my iPod fit better. And there are no instructions on how to use the "twist lock" system other than one small picture on the packaging with a couple of arrows indicating ... well, something. Another gripe is that the cord seems to go out of its way to curl and tangle on itself, more so than normal cords.I expected a better fit and got a worse fit. I returned these for a refund.
