The M580 is designed as an entry-level Bluetooth mobile phone, with a low price that is easily affordable for first-time Bluetooth users. The M580s smooth curves place an emphasis on simplicity and gracefulness. The embedded mobile phone functions are concealed in the two layers, and different-colored rings intuitively hint at the shells opening and closing. The phones dimensions of 88 x 44 x 22 mm represent a golden ratio for mobile phones. The outside screen looks like a flat mirror when not in operation. The M580 stresses convenience and ease of use. Users can save their Bluetooth preferences with a push of the side key. The buttons have different textures and colors so that users can easily keep them apart.
