Premium design, durability and advanced ergonomics

ASUS Zenfone 12 Ultra design and materials

The Zenfone 12 Ultra maintains a minimalist and sophisticated design philosophy, without unnecessary embellishments or extravagance. It features a matte glass back that not only provides a pleasant tactile feel but also significantly reduces fingerprints and smudges. Furthermore, ASUS is committed to sustainability by using a recycled aluminum frame throughout the device.

In terms of dimensions, this is a large-format device (almost 9 mm thick and weighing 220 grams), designed for those seeking an immersive visual experience and who don't mind handling large phones. This size allows the manufacturer to retain features such as a headphone jack , an increasingly exclusive element in premium mobile phones, and a dual stereo speaker system with Hi-Res and Hi-Res Wireless certifications, as well as OZO Audio for enjoying spatial audio.

The IP68 certification ensures complete resistance to dust and water, protecting the device in adverse conditions. Both the front and back use Gorilla Glass Victus 2 , guaranteeing extra protection against bumps and scratches.

The Zenfone 12 Ultra is available in three very elegant colors: sage green, ebony black, and sakura white . Its construction, in addition to conveying a robust and premium feel, pays attention to ergonomic details, incorporating rounded corners and a slightly curved body on the sides for easier grip.
