OpenRock S2 Sport Earbuds Main Features
– 7g Featherlight Comfort and Custom Fit. Crafted with 0.6mm titanium filaments and medical-grade liquid silicone, the weight just 7 grams—lighter than a hummingbird’s feather. Whether scrambling up slopes or navigating dense forests, you’ll forget they’re there until your adventure playlist kicks in.
– Efforless Fit and Built-in Stability. Engineered with a hook-clip mechanism inspired by mountaineering gear, it locks sound in while keeping sweat and rainwater out. The pressure-diffusion design acts like shock absorbers for your ears, redistributing weight across 8 contact points to keep put from sunrise scrambles to dusk descents.
– Triple Defense and Lasting Protection. Ergonomically optimized wearing position allows sweat to slide off naturally and reduces direct contact. Separate BassDirect™ chambers protect PCBA components from perspiration and a waterproof nano-coating on the components increases durability.
– Bluetooth 6.0 & Multipoint Connection. OpenRock S2 features the latest Bluetooth 6.0 for quick transmission and instant pairing. It supports simultaneous connection to two Bluetooth devices with seamless switching.
– 4-Mic AI Noise Cancellation. Four high-quality microphones use beamforming technology in an array configuration, supporting an AI noise cancellation algorithm to effectively eliminate environmental noise. With the wind-resistant structure, even in strong winds, your voice remains crystal clear.
– Dynamic and Unique Design. Crafted with a composite film, OpenRock S2 delivers a subtle 3D visual effect under flat lighting. Its pebble-shaped charging case combines a speckled coating with a textured finish, offering a comfortable grip and a unique pattern on each unit.

About Openrock. The founder of OpenRock, Jack Lee is an avid outdoor enthusiast whose life is connected to nature. He also has a great love of music, which has always been an important part of his outdoor experience, whether he’s running, cycling or camping. He tried a variety of in-ear earbuds and bone conduction headphones, and found that they each had their shortcomings. Driven to solve this dilemma, Jack surveyed hundreds of fellow adventurers and discovered a frustrating truth — people were forced to choose between safety, health, and sound quality. Refusing to accept this compromise, he was determined to change that. In 2018, Jack began developing an air-conduction headphone that merged the best in-ear and bone-conduction technologies while eliminating their flaws. After three years of repeated experiments, his teamfinally overcame the sound leakage and sound quality balance problems. In April 2021, OpenRock was officially founded, with its unique open sound field design, so outdoor enthusiasts can listen to music, but still clearly capture the sound of the wind and birdsong. “The purest freedom amplifies the world, never drowns it out.” This insistence on the communion of nature and technology has become the origin of OpenRock’s deep exploration of air conduction technology. To empower every moment with clear, immersive, and safe audio experiences—whether conquering the outdoors or staying productive in a connected world. OpenRock delivers premium open-ear and professional audio solutions that prioritize comfort, innovation, and seamless communication. To redefine how people experience sound by merging innovation with real-world needs—creating a future where high-performance audio enhances both active lifestyles and professional environments.
