Mine keep breaking after daily use over 6-8 months.
Busy mom, Amazon

Summary: I love the item and sound quality - I hate the fact that no matter how careful I am about the lead/jack - each unit has failed within 6-8 months. OK Amazon have always replaced - I got through 3 but now they have refunded and I either but a 4th or find a different product for use with my iphone.
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.
