Meet OpenRock S2 Sport Earbuds
In a saturated market of earbuds competing for attention, OpenRock S2 arrives as a refreshing standout—combining thoughtful design, athletic performance, and uncompromising audio in a sleek, open-ear format. Whether you’re on a trail, in the gym, or navigating a busy city, the S2 offers a unique listening experience that blends comfort, situational awareness, and premium sound.
One of OpenRock S2’s greatest achievements is its ultra-light hook-clip design, weighing just 7g per earbud. Crafted using ultra-thin 0.6mm titanium filaments and soft liquid silicone, the S2 molds seamlessly to the contours of the ear. It’s a true testament to ergonomic engineering, offering a 3-point support system (ear rim, ear clip, and ear wheel) and a balanced 50:50 weight distribution—ensuring the earbuds remain securely in place without clamping or discomfort. The 20° golden angle—aligned with the natural tilt of the ear canal—further enhances the fit, making the S2 feel like a natural extension of the ear. Whether jogging, jumping, or sprinting, the S2 stays put with zero pressure fatigue.
OpenRock S2 redefines durability with its Triple Sweat-Defense System. The earbuds feature a three-chamber independent design that separates the driver and internal components, minimizing the risk of sweat damage. Add to this a water-repellent nano-coating, sweat-shedding body angles, and a sealed physical button—and you’ve got earbuds ready for serious training. Certified IPX5 water-resistant, the S2 withstands sweat, splashes, and light rain—ideal for high-intensity workouts or outdoor adventures.
Where many open-ear designs compromise sound quality, the OpenRock S2 shines. Powered by 12mm dynamic drivers and BassDirect™ technology, the S2 channels low-frequency energy directly into the ear canal for deep, rich bass with minimal leakage. With up to 30mW output, the sound remains clear, loud, and low-distortion, even in noisy environments. The addition of LDAC support and Hi-Res certification means these earbuds can transmit high-definition audio wirelessly—resulting in crisp vocals, spacious mids, and punchy lows. The LISO 2.0 algorithm automatically balances treble and bass, adapting to your surroundings and activity level.
What elevates the S2 beyond its competitors is the companion OpenRock app, built for real-world utility. Users can toggle between three music modes (Rock, Relax, Boom), adjust EQ settings, and access spatial sound, adaptive volume, and even safe listening limits to protect long-term hearing health. Fitness-focused? You’ll appreciate professional sports sound effects tailored to athletic performance – designed using principles of sports psychology to enhance motivation and endurance during workouts. With 4-mic AI Noise Cancellation, OpenRock S2 ensures voice clarity on calls—even in wind or noisy environments. Beamforming mic arrays and wind-resistant structures effectively isolate your voice, ensuring that commands and conversations come through clean and crisp.
One standout feature that active users will love is the built-in remote camera control. With a quick press of the earbud’s button, users can trigger their phone’s camera to capture photos or videos—no need to fumble with your phone during a hike or ride. It’s a subtle yet brilliant feature that turns the S2 into a multi-functional companion. With up to 8 hours of continuous play and an impressive 32 hours total with the charging case, the S2 easily powers through extended commutes, training sessions, or travel days. And when you’re short on time, a 5-minute quick charge delivers 1 hour of use – perfect for last-minute outings.
The latest Bluetooth 6.0 ensures rapid pairing, low latency, and stable connections. Even better, multipoint connectivity allows simultaneous connection to two devices—seamlessly switching between phone calls and media without manual pairing.
The OpenRock S2 looks as good as it performs. Its sleek composite film finish creates a dynamic 3D shimmer under flat lighting, while the pebble-inspired charging case offers a tactile, speckled surface that’s both stylish and easy to grip. Each unit features a subtly unique pattern—adding a personal touch to an already premium product. The OpenRock S2 isn’t just an evolution—it’s a redefinition of what open-ear earbuds can achieve. With cutting-edge audio, ergonomic innovation, and thoughtful features like camera control and health tracking, it hits a rare sweet spot between performance and versatility.

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.
