SHENZHEN, China, Sept. 20, 2026 /PRNewswire/ -- 1MORE S20 Ultra Clip-On Earbuds combine advanced acoustic architecture, all-day comfort, intelligent features, and versatile performance to redefine the ear-clip headphone experience.

1MORE, a professional audio brand, has officially launched the 1MORE S20 Ultra Bluetooth earbuds, the brand's flagship open-ear ear-clip headphones for the year. Bringing together nine core technologies, the 1MORE S20 Ultra delivers major improvements in sound quality, comfort, and versatility. Designed to address key challenges associated with traditional open-ear headphones—including sound leakage, fit stability, and call quality—the 1MORE S20 Ultra earbuds introduce a more elevated listening experience that combines an open design with immersive sound and smart functionality.

A New Acoustic Architecture for Detailed, High-Resolution Sound

The 1MORE S20 Ultra Clip-On earbuds feature a three-magnet speaker acoustic architecture designed to enhance full-frequency sound reproduction. The architecture delivers deeper low frequencies, accurate midrange reproduction, and clear high frequencies, allowing musical passages to retain greater layering and a fuller, more three-dimensional presentation.

The 1MORE S20 Ultra Open Earbuds have also received Hi-Res Wireless certification and support LDAC lossless audio decoding, which provides three times the decoding efficiency of traditional transmission, enabling the headphones to reproduce high-definition audio with greater detail and bringing a more studio-like listening experience to everyday use.

To create a more immersive listening experience, the 1MORE S20 Ultra earbuds incorporate 360° panoramic surround sound technology. The technology creates an expansive sound field designed to deliver an immersive, theater-like listening experience whether users are commuting, relaxing at home, or enjoying entertainment on the go.

The earbuds also feature SDT Sound Focusing 2.0 technology, which uses directional sound transmission to focus audio toward the ear. This helps reduce sound leakage and addresses the "small speaker next to your ear" effect often associated with open-ear headphones, providing a more comfortable and private listening experience.

Designed for a Secure and Comfortable Fit

1MORE S20 Ultra Clip-On earbuds are designed to balance long-term comfort with a secure fit. Its high-performance nickel-titanium memory wire and C-shaped ear-clip structure have undergone testing for up to 10,000 bends, with the design delivering a reported 40% improvement in stability. This construction is paired with an ergonomic, micro-in-ear comfort design intended to keep the headphones securely in place, including during active use and exercise.

1MORE S20 Ultra earbuds further incorporate BalanceAIR+ 3.0 comfort technology. Based on extensive human-ear data, its cloud-like air-cushion chamber is designed to distribute pressure more evenly around the ear. The result is an open-ear wearing experience designed to minimize stuffiness and pressure while maintaining comfort during extended listening sessions.

A lightweight construction further contributes to the wearing experience. 1MORE S20 Ultra's cloud-inspired lightweight structure reduces its weight by 60% compared with traditional ear-clip products, while a nano-scale breathable material helps create a more comfortable, breathable fit designed for extended, all-day wear.

Intelligent Features for Everyday Use

For calls, 1MORE S20 Ultra is equipped with a four-microphone ENC intelligent noise-cancellation system. The front and rear microphones work together to capture the user's voice while separating environmental and wind noise. This is designed to maintain clear voice communication in outdoor and commuting environments, including situations with higher levels of surrounding noise.

1MORE S20 Ultra headphones provide up to 8.5 hours of playback on a single charge, while the charging case extends total battery life to up to 40 hours. This capacity is designed to support multiple days of commuting and travel without requiring frequent recharging.

The headphones are also IPX5 water-resistant, protecting against sweat and water splashes. This makes 1MORE S20 Ultra earbuds suitable for a range of active scenarios, including running and workouts. These functions are designed to support a variety of everyday scenarios; through the dedicated 1MORE app, users can access additional headphone functions, including headphone finding, customized sound adjustment, and seamless switching between two devices. 1MORE S20 Ultra earbuds also adopt Bluetooth 6.0, delivering low-latency and stable wireless transmission for smoother audio and video synchronization and a more seamless transition between work and entertainment.

The All-Around Ultra for Open-Ear Audio

With advancements spanning acoustics, comfort, connectivity, call quality, and intelligent functionality, the 1MORE S20 Ultra Clip-On earbuds bring together nine core technologies to create an all-around open-ear audio experience.

1MORE S20 Ultra builds on 1MORE's expertise in acoustic technology while introducing new solutions designed to address several longstanding challenges of open-ear earbuds, including sound leakage, wearing stability, and voice-call performance. By combining high-resolution audio capabilities, an ergonomic ear-clip design, intelligent features, and versatile everyday performance, 1MORE S20 Ultra earbuds establish a new benchmark for the open-ear listening experience.
