This year Apple officially unveiled the all-new iPhone 17 series, and for the first time introduced the iPhone Air with an entirely new design language, showcasing the brand's precise strategy for positioning its product lineup. Each model is tailored to a different type of user, so whether you're focused on features, budget, or design preference, there's an ideal choice for everyone.

The iPhone 17 marks a significant leap forward in hardware specs compared to previous generations, and can rightly be called a showcase of "flagship features trickling down." Apple has brought core technologies previously reserved for the Pro series into the standard model, including the A19 chip, a 120Hz ProMotion adaptive refresh-rate display, and an upgraded main camera module, letting budget-conscious Apple fans enjoy a more premium experience.

For power users and photography enthusiasts, the iPhone 17 Pro and iPhone 17 Pro Max take hardware configuration a step further. In addition to the new A19 Pro chip, the body uses a unibody aluminum construction with a vapor chamber cooling design, effectively improving stability and performance during extended use. The camera system is fully upgraded to three 48-megapixel lenses, supporting up to 8x optical-quality zoom. The front camera adopts a new square sensor with resolution boosted to 18 megapixels, supporting center-stage tracking and dual-capture video recording, greatly enhancing flexibility for selfies and content creation.

On the memory side, RAM has been upgraded to 12GB, and paired with deep iOS optimization, it delivers outstanding performance in multitasking, running large apps, and gaming, gradually closing the hardware gap with the Android camp.

As for the debut of the iPhone Air, it represents Apple's fresh take on ultimate slim-and-light aesthetics. The body is just 5.6mm thick and weighs only 165g, featuring a titanium frame and a 6.5-inch Retina XDR display, achieving an unprecedented level of feel and portability. Although battery capacity and the camera module are somewhat reduced due to the space constraints, it still retains core features such as the A19 Pro chip, MagSafe wireless charging, and Face ID, making it ideal for users who value design and light everyday use.

Notably, the iPhone Air uses a folded main-board design with a modular flex-cable layout, which many see as Apple laying the technical groundwork for future foldable devices. Should an iPhone Fold arrive down the road, the Air's design language and technical architecture could well become an important foundation for it.


Following Apple's keynote, well-known Japanese phone accessory brand DeFF simultaneously launched its next generation of dedicated accessories supporting the iPhone 17 series and iPhone Air, demonstrating its keen grasp of market trends. This new lineup covers a range of high-performance protection solutions, including:

  • ULTRA HARD GLASS Tempered Glass Screen Protector: Featuring 7x hardness technology, effectively improving scratch and impact resistance to protect the screen from everyday wear.
  • DURO Kevlar Fiber Ultra-Slim Case: Combines light weight with high strength, providing solid protection while keeping the near-naked feel of the phone.
  • DURO RINGMASTER Kevlar Fiber Drop-Proof Stand Case: Integrates a stand function with military-grade drop protection, suited to a wide range of use cases.
  • CAMERA LENS COVER Aluminum Alloy Lens Protector: Precision-cut to fit the camera module, effectively preventing scratches and dust ingress.
  • CLEAR HYBRID CAMERA LENS COVER Clear Lens Protector: Made from a highly transparent material that protects the lens without compromising shooting quality.

Through a variety of materials and precision craftsmanship, DeFF offers iPhone users well-rounded protection options for everyday use, outdoor activities, or creative shooting alike.

ULTRA HARD GLASS Tempered Glass Screen Protector Series
Available in borderless "high-transparency" and "nano matte" finishes, both cut directly from genuine Japanese AGC DragonTrail Pro glass at roughly 0.4mm thickness, with no thinning process applied so as not to compromise glass strength — resulting in an ultra-high-strength screen protector that far surpasses ordinary tempered glass.

Compared to the previous-generation DragonTrail X, the Pro version has a reinforced stress layer, making it not only tougher but also more resistant to impact, reducing the risk of cracking. The newly launched "nano matte" finish applies an extremely thin special matte treatment to the glass surface, cleverly blending the crisp image quality of the clear version with the smooth feel of the matte version, while adding anti-glare (AR) performance — striking an excellent balance among all three.

In addition, every glass screen protector is treated with an anti-fingerprint coating, effectively reducing smudges and making it easier to wipe clean, keeping the screen looking pristine.


DURO Kevlar Fiber Ultra-Slim Case
Available for iPhone 17, iPhone 17 Pro, and iPhone Air, made from 100% DuPont® Kevlar® — one of the toughest materials on earth. Featuring an ultra-thin 0.65mm design and weighing only about 19 grams, it's light yet strong, with a strength five times that of steel.

The frame cutouts have been fully removed and the edges finely refined, making swipes and gestures smoother and delivering an almost "bare-phone" feel. The area around the camera is raised for extra protection, effectively preventing scratches and impact, while still supporting wireless charging — balancing everyday use with maximum protection.

CAMERA LENS COVER Aluminum Alloy Lens Protector
Available for iPhone 17, iPhone 17 Pro, iPhone 17 Pro Max, and iPhone Air, made from twice-hardened glass paired with an aluminum alloy lens cover body, combining a sturdy, sleek aluminum alloy frame with highly transparent chemically strengthened glass to fully protect the camera and surrounding structure.

The precision design keeps the gap between the lens glass and the protective cover to under 0.1mm, effectively minimizing optical interference and maintaining clear image quality. Its simple form closely follows the original device's contours, balancing aesthetics with practicality.

CLEAR HYBRID CAMERA LENS COVER Clear Lens Protector
Available for iPhone 17, iPhone 17 Pro, iPhone 17 Pro Max, and iPhone Air, made from AGC 0.25mm soda-lime glass paired with CNC-machined acrylic, offering high transparency and a refined finish.

The gap between the protector and the lens is just about 0.05mm, effectively minimizing optical interference and maintaining clear image quality, while closely following the original device's design for a simple, sleek look that balances aesthetics with practicality.

Using a single-piece camera-module protector significantly reduces the risk of scratches to the aluminum surface.


Now that we've covered the product lineup, let's take a hands-on look at the ULTRA HARD GLASS Tempered Glass Screen Protector (nano matte), DURO Kevlar Fiber Ultra-Slim Case (slim version), DURO Kevlar Fiber Ultra-Slim Case (Special Edition), and the CAMERA LENS COVER Aluminum Alloy Lens Protector installed on the phone.

Since the iPhone 17 Pro has undergone significant design changes, it's essentially incompatible with accessories from previous generations. That's why the DeFF design team invested considerable effort in redeveloping this new lineup of accessories, striving to create products that combine function and aesthetics without compromising the original device's design.

Among these, the ULTRA HARD GLASS Tempered Glass Screen Protector continues to use Japan's AGC flagship-grade DragonTrail Pro raw material, cut directly to about 0.4mm thickness, deliberately avoiding a thinning process, and processed with precision heat-curing technology to achieve a perfect balance of responsive touch and high impact resistance. In response to user feedback, it has also switched entirely to a "fully transparent, borderless" design, making the viewing experience purer and more immersive.

Besides the highly transparent base version, for users who frequently use their phone outdoors or are avid mobile gamers, we recommend the newly launched nano matte version. This finish applies an extremely thin special matte treatment to the glass surface, combining the crisp image quality of the clear version with the smooth feel of the matte version, while offering anti-glare (AR) performance — thoroughly addressing the image-quality and glare shortcomings of matte glass protectors in the past.

True to DeFF's signature minimalist style, the packaging design is clean and understated, clearly labeled with the corresponding phone model to help users quickly identify and shop.
The glass protector reaches a hardness of Mohs 7 or higher.
The glass protector demonstrated here is the nano matte version, which effectively reduces glare.
And it doesn't affect the viewing experience either.

DURO Kevlar Fiber Ultra-Slim Case (slim version) & DURO Kevlar Fiber Ultra-Slim Case (Special Edition)

The packaging has been fully switched to all-paper materials, responding to growing environmental awareness by cutting down on plastic use and reducing environmental impact. Beyond its products, DeFF continues to think about sustainability, so its cases don't just protect your phone — they protect the planet too.
The slim version uses a fully open camera-module design that preserves the phone's original contours for a sleeker feel; the Special Edition fully wraps the camera area for enhanced protection. Each has its own character, so you can choose whichever suits your habits and style.
The designers deliberately hid the brand logo on the inner layer from the very start of the design process, keeping the case's exterior ultra-clean and embodying the design philosophy that "less is more."
This is the most talked-about colorway this time — "Cosmic Orange." The author has already applied the DeFF CAMERA LENS COVER Aluminum Alloy Lens Protector, so the camera area appears black rather than the phone's actual orange tone.
Using the DURO Kevlar Fiber Ultra-Slim Case in person, you can really feel its ultra-slim design — just 0.65mm thick, yet thanks to the woven Kevlar fiber construction, it offers excellent impact resistance, completely overturning the stereotype that "thinner means more fragile." Best of all, it retains an almost bare-phone feel, striking the perfect balance between protection and touch.
The product designer says that to preserve a bare-phone feel for the buttons, the left side deliberately uses an open-cutout design, ensuring smooth operation and a natural touch.
The right side likewise uses an open-cutout design.
The camera module uses a fully open design, which not only fully showcases the new camera module's look but also improves compatibility with third-party camera lens protectors, giving users more pairing options.
The bottom cutouts use a symmetrical design, balancing looks with function for an even more refined finish.
The DeFF CAMERA LENS COVER Aluminum Alloy Lens Protector uses a familiar cap-style design; once applied, you can still faintly see the orange camera bezel underneath, adding depth and visual layering while also making it easy to remove and swap out lens accessories later. The lens edge also features a ring-pattern detail, reminiscent of a mirrorless camera lens, showcasing a more professional feel and craftsmanship.
The surface also receives multiple special anti-fouling treatments, offering anti-slip and smooth-touch properties that resist fingerprints and smudges, keeping everyday use clean and neat.
Paired with the DeFF ULTRA HARD GLASS Tempered Glass Screen Protector (Nano Matte) on the front, this is especially suited to users who dislike fingerprints lingering on the screen. The matte surface is not only smooth to operate, but also effectively reduces fingerprint smudges, keeping the screen clean and visually clear.

Next, let's take a look at the DURO Kevlar Fiber Ultra-Slim Case (Special Edition) installed on the phone.
Crafted from 100% DuPont® Kevlar®, at just about 0.65mm thick, it's ultra-slim yet tough, delivering a one-piece, sleek finish and an almost bare-phone feel. Kevlar fiber is five times stronger than steel of the same weight, yet only about half the weight of fiberglass; its manufacturing process is nearly identical to that of dry carbon fiber, with many steps done entirely by hand, and every piece carefully finished, showcasing an extreme dedication to detail and craftsmanship.
Just like the slim version, the brand logo is likewise cleverly hidden on the inner layer, continuing the ultra-minimalist design language for an even more understated, sleek look.
The Special Edition takes protection even further, with an aluminum alloy frame added around the camera lenses and a fully wrap-around design that effectively reinforces lens protection, reducing the risk of camera-module damage if the phone is dropped. This case also passes U.S. military-standard MIL-STD-810H testing, so its protective performance can withstand rigorous scrutiny, offering greater peace of mind for everyday use.
Just like the slim version, to preserve a bare-phone feel for the buttons, the Special Edition also uses an open-cutout design, ensuring smooth operation, a natural touch, and continuing the same minimalist design philosophy.
The right side is also an open-cutout design.
The case features a built-in metal ring that's fully compatible with MagSafe accessories, and of course also supports wireless charging — making everyday use more convenient with no compromises.
