Earbuds are comfortable and the sound is good - but not as good as the Shure earphones (I have both). Microphone sound is also good, but needs to be close to the mouth to avoid the "talking in a well" sound. There is no on/off button on the microphone, so you have to screw with the iPhone itself to accept/end phone calls. I would rate this set between 3 and 4 stars if they had that quick button, which I think is a key feature required in a phone/audio headset.
