The iPhone gets all the buzz, but a lot of cell phones store and play MP3s. They may not hold nearly as many songs as your regular MP3 player, but they do let you bring a few key tunes along to serve as your own personal soundtrack. The only downside is you have to choose between using the corded stereo earbuds, which deliver the sound the way it was meant to be, or your much more convenient wireless Bluetooth headset, which only lets you listen out of one ear, defeating the whole purpose of having a stereo phone.

The new Plantronics Voyager 855 Bluetooth headset gives you both - stereo sound in a convertible wireless headset. Sharing many of the features of their other headsets - compact, lightweight design, the one-touch buttons that control music and calls, the sliding mic boom and clarity enhancing technology of AudioIQ - the 855 also comes with a detachable stereo ear bud and cable that clips to the headset and doubles as an ear clip.

The 855's earbuds come in three sizes to ensure a personalized fit, and are designed to seal out surrounding noise so you can hear your conversation or music more clearly. (Never mind the approaching fire truck.) A single button lets you switch between calls and music.

When you're not using the extra bud just snap out the cable, converting the 855 back into a mono headset. A single charge gives you 7 hours of talk/listening time and about 200 hours standby time.
