Shortly after the 2026 Apple Keynote, ESR unveiled its lineup of accessories for the new Apple devices. The focus is on cases, screen protectors, and charging solutions for the foldable iPhone Duo and the iPhone 18 series, along with new models for AirPods and Apple Watch. The accessory manufacturer is thus responding to Apple’s latest product announcements within just a few days.

On September 9, 2026, Apple unveiled the iPhone Duo as the first foldable iPhone, along with the iPhone 18 Pro series, new AirPods, and an updated Apple Watch. The iPhone Duo starts at 2,299 euros in Germany for the 256-GB version; pre-orders are available starting October 16, and sales begin on October 23. The new ESR collection is timed precisely to coincide with this window.

ESR Cases with Flex Stand for the iPhone Duo and the iPhone 18 Series

For the foldable iPhone Duo, ESR has developed a dual-purpose Flex Stand that can rotate 180 degrees and holds the device securely in both the folded and unfolded positions. A precision hinge made of high-strength zinc alloy ensures smooth opening and closing. If you don’t need the stand, you can use it as a finger loop instead.

Three case lines form the core of the new collection. The Atelier Vegan Leather Magnetic Case features a back made of vegan leather with a dirt-repellent coating and a stain-resistant TPU surface, along with military-grade protection and a magnetic force of 1,400 grams. The Classic Hybrid Magnetic Case has a slimmer design and, according to SGS testing, is said to yellow significantly more slowly; ESR cites a durability equivalent to approximately six months of real-world use. The Cyber Tough Magnetic Case is the most rugged of the three, offering seven-fold military-grade drop protection for the iPhone 18 Pro and Pro Max and four-fold drop protection for the iPhone Duo, also featuring a Flex Stand.

For the iPhone 18 series, the stand’s viewing angle can be adjusted between 15 and 69 degrees in portrait and landscape orientation. All three cases are available for the iPhone 18 Pro and Pro Max.

Screen Protector with Corning Glass

With the UltraFit Armorite Pro Screen Protector, ESR combines “Accessory Glass by Corning” with its own protective technology. According to the manufacturer, the screen protector offers ten times the impact resistance and up to twice the scratch resistance compared to standard screen protectors. An UltraFit frame is designed to make installation easier and ensure precise alignment. The screen protector is planned for both the iPhone Duo and the iPhone 18 series.

Chargers for Home, Office, and Car

Product Features Special Feature
ESR Cyclone 25W Magnetic Charging Pad with CryoBoost 25 W (Qi2) Active cooling, adjustable stand, IFA Innovation Award 2026
ESR Xtend 45W Charger Up to 60 W dynamic Approx. 94 cm retractable cable, compact housing

The Cyclone charging pad combines wireless charging based on the Qi2 standard with active CryoBoost cooling and has already been honored as a “Honoree” at the IFA Innovation Award 2026. The two Xtend chargers are designed for anyone who wants to avoid carrying a separate charging cable while on the go.

Accessories for AirPods, Apple Watch, and your wallet

Beyond the iPhone, ESR is expanding its lineup with three additional products. The Geo Magnetic Wallet Stand (Grip) securely holds up to five cards with a holding force of 3,200 grams; its stand can be adjusted between 15 and 170 degrees and supports the new Siri voice activation for the “Find My” feature. To match the new iPhone color option, Dark Burgundy, the wallet is also available in this shade. The Cyber FlickLock magnetic case for AirPods features a sliding clasp for one-handed operation. ESR states that it has tested the mechanism over 20,000 cycles; in addition, Air-Guard corners are designed to protect against drops. The case is available in nine colors. Also new to the lineup is the Equinox wristband for the Apple Watch, ESR’s first in-house watch strap: A pin-and-fold clasp, ventilation cutouts, and skin-friendly material are designed to make it suitable for everyday use.

“Our motto, ‘Tech Made Easier,’ reflects our belief that technology should make life easier, not more complicated,” says ESR CEO Tim Wu about the new collection. The goal is to create an ecosystem of accessories that works together as seamlessly as Apple devices themselves.

Pricing and Availability

The manufacturer has not yet released specific prices for the individual ESR products; on its website, the iPhone Duo models are currently listed as “Coming Soon.” The complete lineup, including charging solutions, is expected to be available via the official ESR website and the ESR Amazon store. Since sales of the iPhone Duo begin on October 23, at least some of the accessories should be available at the same time.

With cases, screen protectors, chargers, and accessories for AirPods and the Apple Watch, ESR now covers nearly the entire new Apple ecosystem—from the iPhone Duo and the iPhone 18 series to wearables. We’ll update this article as soon as prices and exact release dates are confirmed.
