Flat yet trim

Weighing just 8 grams (0.28 ounce), the Plantronics M55 is thin, svelte, and rectangular. Attractive silver-metallic edges complement its glossy black hue. A discreet call button etched in gray is placed on the headset's front face, while a hidden LED sits below the surface.

Small and sophisticated

One of the best attributes of the Plantronics M55 is its tiny size, which makes it more discreet to use. The headset's light 0.28-ounce weight is also very comfortable.
