Check latest prices		CMO America ZipKord retractable mobile headset  The small, well-cushioned earpiece on the ZipKord fits snugly but softly in your ear canal, and callers had no trouble hearing us with the in-line microphone. Another plus: The cord expands to 32 inches and rewinds with ease, and the outside of the small case includes a metal shirt clip, so it's easy to walk around with this headset. There's also a model available for Nokia phones with a four-prong plug.
Check latest prices		Logitech Mobile Earbud Miniboom The earpiece on the Miniboom doesn't offer the most comfortable fit, and the case is a bit large and cumbersome for walking around outdoors, but the audio quality is good. A multifunction button (call answer/end, mute, redial) on the earpiece is a nice touch, and a handy switch rewinds the cord back into its casing. Just be careful not to touch it in the middle of a conversation.
Check latest prices		Logitech Mobile Earbud Retractable This Logitech offers the same features as the Earbud Miniboom, only the microphone is integrated into the earpiece. Callers frequently noted that we sounded muffled, a complaint we didn't get when using the Miniboom version.
Check latest prices		Plantronics MX100s mobile and music headset The Plantronics MX100s comes with an extra earpiece and an extra jack for use with an MP3 player. A switch on the in-line remote lets you toggle between phone and music settings and includes a volume control. When used with a cell phone, however, the extra cords makes for a tangled mess. We also found the earpiece volume to be quite low during phone calls. Designed to capitalize on the growing cottage industry of iPod accessories (it will be available from Apple stores and Apple.com), the MX100s also fails as a pair of stereo earbuds, performing no better than what you'd find included with your MP3 player--that is, not very well. At $40, inferiority comes at a heavy price.
Check latest prices		Plantronics MX300 The Plantronics MX300's WindSmart technology is designed to reduce the noise created in windy environments. Indoors, callers said we sounded loud and clear--even more so than with the excellent Shure QuietSpot headsets. We came though clear outdoors, too, but we still had to speak a little louder than we would inside. The rubber Flex Grip fastens under your earlobe comfortably, and the two-way RetractPro lets you adjust the wires for both the earpiece and the connection to your phone. Though a bit pricey at $45, it's worth it if you need to be heard when on the move.
