Summary: I have had two pairs of these headphones as they sem to be the best iPhone compatible over ear cans for the price. However, i think Sennheiser really need to look at the cable connections. Both have failed through 'normal' use. I say 'normal' because i put the phone they are connected to in my front pocket (doesn't everyone?) Unfortunately the cable cannot withstand this type of wear.
Summary: My children have a AKG 451 and the Sennheiser HD 218. Despite being half the price of AKG when bought the Sennhieser £28 provides matching sound quality including the base. Quality is good. They haven't had issues reported by others. Highly recommended.
Summary: I have a pair of very expensive B&W headphones which sound great. I don't like using them while running or exercising... in ear buds are too uncomfortable for me. These sound great for day to day use with most types of music. For what you pay they are great.
Summary: Great value for money. I was looking for decent quality headphones with a microphone so that it can double up as a handsfree for my iPhone. Most other brands are quite expensive. This is a decent quality set, which I find great value for money.
Summary: I bought these for use with my iPhone so that I could listen to music and answer the phone when necessary. They work absolutely perfectly, the remote does all of the iPhone remote functions and the mic is clear. My only criticism would be that they let in quite a lot of noise so don't buy them expecting over-ear noise blocking or loud sound. They sit just on top of your ears. Great value.
Summary: These headphones are by far the best sounding headphones I've ever owned. Having upgraded from a small pair of earphones for my personal music, this is a huge difference. The bass sounds extremely clear without sacrificing the clarity of the rest of the sound. Very comfortable and the iPhone headset is very handy. Would thoroughly recommend to all iPhone users.
