It doesn't fit,
Amazon Verified Purchase(What is this?)
This review is from: Jabra Rhythm Corded Stereo Headset with In-Line Microphone - White (Electronics)
As stated by others the headset is impossible to fit properly into the ear. The will fall out of your ear the minute you start to move your head. Neither of the rubber bud fits, so I had to use my own. The sound seems okay though.
