Many phone case options claim to be "shockproof," but at ESR, we back that up with military-grade certifications, specifically MIL-STD-810H. ESR cases integrate advanced defense technology to safeguard your device against real-world impacts.

Here is how ESR builds comprehensive protection that keeps your phone safe, slim, and fully functional:

1. Advanced Impact Dispersion Technology (The Shock Test)

Our cases feature multi-layer designs that absorb and dissipate energy, reducing stress on your phone’s internal components. This isn’t just about passing a military-grade drop test—it’s about surviving whatever life throws at your phone.

2. Reinforced Anti-Torsion Frame (The Twist Test)

Standard cases often fail under twisting pressure. ESR cases use high-rigidity materials to stabilize your phone, preventing screen cracks and component damage from torsion or angled impacts.

3. Comprehensive 360-Degree Functionality (The Smart Design)

Protection shouldn't mean sacrificing convenience or core functionality:

• Screen and Camera Guard: Our precisely engineered raised edges around the screen and the significantly larger camera lenses (especially on the iPhone 17 series) ensure that these vulnerable surfaces never make direct contact with flat surfaces. This precision is custom-tailored for every specific model.
• MagSafe/Magnetic Power: Unlike generic rugged cases, our designs include powerful magnetic arrays that guarantee flawless compatibility with MagSafe charging and accessories. This is critical for iPhone users who rely on the ecosystem, and for Samsung Galaxy users, our integrated magnets unlock MagSafe convenience (including our heat-dissipating CryoBoost technology)—proving that supreme protection can be perfectly slim and functional, regardless of your phone brand.

ESR’s rugged phone case designs combine award-winning engineering, slim profiles, and complete protection, making them a top choice for any user.

ESR offers versatility and style in addition to protection:

• MagSafe Wallet and Phone Case Combo: Carry essentials without adding bulk while maintaining full MagSafe functionality.
• DIY phone case ideas and designs: Customize your custom phone cases with ESR’s design options to express personal style.
• Material innovation: Compare different materials to find your perfect balance of slimness, flexibility, and impact resistance.

For Samsung users, our Samsung Galaxy Phone Case and Samsung MagSafe Case support Qi2.2 25W fast charging and work seamlessly with ESR’s 3-in-1 chargers
