The S20 Ultra features a three-magnet speaker architecture engineered for high-frequency clarity and deep bass. To mitigate the typical audio bleed associated with open-ear designs, 1MORE implemented its SDT Sound Focusing 2.0 technology, which directs audio specifically toward the ear canal. The device has earned Hi-Res Wireless certification, positioning it as a premium option for listeners who prioritize spatial accuracy and studio-like detail in a non-isolating form factor.

Comfort and durability remain central to the design. The earbuds utilize a nickel-titanium memory wire frame capable of enduring 10,000 bends, paired with an air-cushion chamber system dubbed BalanceAIR+ 3.0. This combination reduces physical pressure during long listening sessions. The hardware is further reinforced by an IPX5 water-resistance rating and a four-microphone system for AI-enhanced noise cancellation during calls.

Battery performance reaches 8.5 hours on a single charge, with the compact carrying case providing a total of 40 hours of playback. Beyond the physical build, the integration of Bluetooth 6.0 aims to minimize latency for video synchronization and multi-device switching. The product is currently available globally via 1MORE’s website and Amazon, with an introductory 20% discount applied to the launch price for the first 30 days.
