Expert Praise

They look like they come straight from the future with their cyberpunk-inspired aesthetic, but I also love how they’re multi-functional

Why It Made The List

A frosted iPhone 17 Pro Max case with more attitude than the usual clear TPU shell, built for protection, grip and a cleaner high-tech look. The translucent finish keeps the phone visible without looking cheap, while the one-piece TPU body uses a dual-sided IMD process to resist scratches and stop the pattern fading. At 53 g, it stays light, with an enhanced frame for grip, aluminium buttons for a more tactile feel, and an elevated aluminium camera ring for lens protection. A silicone pad and aluminium plate help move heat away, while the colour-shift sensor reacts as CPU temperature rises. MagSafe compatibility and subtle glow-in-the-dark accents finish it off.

MORE DETAIL

This design-forward iPhone case is built for people who want a slim, technical case with a cleaner look than standard plastic or silicone.

For the iPhone 17 Pro Max version, the frosted translucent TPU body is paired with aluminium buttons and an aluminium camera ring for a more precise, hardware-led feel.

The case is made from 100% one-piece durable TPU using a 2-sided IMD process, which helps protect against scratches and keeps the graphic finish from fading over time.

The frosted finish gives the case a clean, modern look, with a choice of translucent grey or translucent white.

Aulumu’s CoolHyper cooling system uses a silicone pad and aluminium plate to help transfer heat, with the brand stating up to 46% better heat transfer and a 2–3°C cooler result than standard cases.

A colour-changing smart sensor reacts as CPU temperature rises, giving the case a functional temperature indicator as well as a more technical visual detail.

Glow-in-the-dark accents create subtle illuminated lines at night, designed to add visibility without overwhelming the look.

The luminous TPU needs to absorb light first, so the glow is strongest after exposure to sunlight or a flashlight.

The elevated aluminium camera guard is designed to protect the lens area from daily scratches, bumps, and surface contact.

A fully wrapped Camera Control button cover keeps native iPhone functions responsive while adding full button protection.

The enhanced frame is designed for a secure, non-slip grip, while the independent aluminium buttons give a more tactile response in daily use.

Strong magnetic support keeps it compatible with MagSafe accessories and wireless charging.

The iPhone 17 Pro Max version weighs 53g.
