Design and Build
The Sony Ericsson K550 exhibits a simplistic, yet elegant design typical of mid-2000s mobile devices. Its compact dimensions—102 x 46 x 14 mm—and light weight of 85 grams make it notably portable and easy to handle. The phone features a traditional candy bar form factor with a Mini-SIM slot, fitting well in hand and pocket. Its aesthetics are enhanced by multiple color options such as Jet Black, Pearl White, Plum Ruby, and Sophisticated Silver, catering to a variety of personal tastes.
