Apple’s foldable iPhone Duo demands accessories built around its unique design, and ESR has answered with a lineup engineered specifically for it. The Classic Hybrid Magnetic Case with Flex Stand and ESR Atelier Magnetic Case with Flex Stand lead the range, pairing a versatile rotating stand with hinge-focused protection. Rounding things out, ESR’s Xtend 45W and 100W retractable chargers keep your Duo—and everything else—powered up at home, on the road, or in transit.

ESR Classic Hybrid Magnetic Case with Camera Control and Flex Stand

ESR

Owning a foldable iPhone means rethinking what a case should do. It’s not just about shielding a screen anymore—there’s a hinge to protect, two surfaces to consider, and a form factor that changes shape throughout the day. ESR’s Classic Hybrid Magnetic Case, with its built-in Flex Stand, is designed specifically around that reality.

The standout feature is the 180° rotating, folding stand, built from durable zinc alloy for long-term stability. A precision hinge with carefully tuned damping force lets it open and close smoothly, holding steady at whatever angle you choose—whether the Duo is folded or unfolded. ESR rates the mechanism to 3,000 open-and-close cycles, and the added bracket makes the phone easier to grip when you’re not using the stand at all.

Protection is equally considered for a foldable’s unique vulnerabilities. A polycarbonate and acrylic back pairs with a TPU frame and reinforced hinge coverage to guard against scratches and daily wear, alongside upgraded Air Guard corners with contoured cushioning to provide further drop protection. Raised edges add another layer of defense around the phone’s most exposed points.

None of this comes at the cost of bulk. The case keeps a slim 1.5mm profile at the back and remains compatible with 25W Qi2 fast charging, so you’re not sacrificing convenience for protection. A strong 1,500g magnetic hold keeps MagSafe accessories securely attached, from wallets to chargers to mounts.

For iPhone Duo owners, that combination matters: a case that protects the hinge and both surfaces, doubles as a genuinely useful stand for calls, video, or recipes, and still feels slim and magnetically secure in daily use. It’s a thoughtful answer to a phone that asks more of its case than any iPhone before it.

ESR Atelier Magnetic Case with Flex Stand

Not every foldable owner wants a case that looks like protective equipment. ESR’s Atelier Case takes a more refined route, pairing a soft silicone leather finish with a built-in Flex Stand, and it’s aimed at business users and anyone who cares how their phone looks.

The material is the standout. The silicone leather has a smooth, leather-like feel, and an oleophobic coating resists daily stains so it wipes clean easily. ESR says it also resists scratches, wear and fading. A microfiber lining sits against the phone, and colors run from Black and Light Gray to Deep Burgundy and Misty Blue.

The Flex Stand rotates and folds 180°, supporting the Duo folded or unfolded, in portrait or landscape. It doubles as a grip when you aren’t propping the phone up.

Protection is built around the fold. A TPU frame, raised edges (2.3mm at the screen, 1.6mm at the camera bar) and extra hinge coverage guard against scratches, dust and daily wear. A 1,400g magnetic hold keeps MagSafe charging and accessories working.

For Duo owners who want a premium look without giving up a stand or hinge protection, it’s a polished option.
