Review on Black KTC Aluminum Ear Buds with In-Line Controls for iPhone/iPad/iPod - Koss iL200k by Danielle Smith

These headphones are a mixed bag. The microphone works great and I've even successfully used it with Siri while cycling. The controls are easy to use without looking. When it comes to voice calls, the sound is excellent. For music, however, they are tinny and lack range. High and low frequencies are missing and the cymbals almost sound out of tune. So they're great for phone calls, but not great for music. Update: After a longer runtime, the sound improved, especially at high frequencies. The bass is still missing, but I find it acceptable for listening to music on the go.
