Summary: The headphones have an amazing sound quality, very clear and crisp highs/mids and a surprising bass with the right ear bud tips, the mic is spaced relatively well from the ear piece so that it rests near your mouth naturally (more your neck.. though). I would give it 5 stars for its quality/price alone, but without durability, it is useless. This set lasted me about 3 weeks, until the left earphone stopped working completely, then the microphone, now the other ear bud.
Summary: OK, I know what it's like reading reviews when you know nothing about the person. Here's where I'm coming from - I'm a professional sound man. I use Senheisser HD25s as my main headphones and they sound terrific. I need a pair of in-ears for jogging as the ones bundled with the iPhone are atrotious.
