Xiaomi also launched three new wearables at its Berlin event: the Xiaomi Open Wear Stereo Pro (previously launched in China), the Xiaomi Watch S4 41mm, and the Smart Band 10 Glimmer Edition, alongside the Xiaomi 15T series.
Xiaomi Watch S4 41mm -
Xiaomi describes the Watch S4 41mm as a compact smartwatch that blends elegant design with powerful health and fitness tracking. It features a 1.32-inch AMOLED display with up to 1500 nits peak brightness in High Brightness Mode, a slim 9.5mm profile, and weighs just 32g. Strap options include leather, fluororubber, and Milanese styles.
The Milanese strap comes in a special Sunset Gold Edition, highlighted by a lab-grown diamond set into the crown for a touch of luxury. Users also get access to 200+ watch faces, including playful animal-themed designs.
The Sunset Gold Edition incorporates a high-precision heart rate sensor enhanced with Xiaomi’s proprietary algorithm. Running on HyperOS 3, it delivers accurate and stable performance tracking during workouts. Sleep monitoring now includes multidimensional analysis and a 21-day guided improvement program, providing actionable insights for better rest and healthier sleep patterns.
In addition to these capabilities, the Watch S4 41mm supports GPS tracking, 5ATM water resistance, and over 150 sports modes, including swimming and skiing, making it versatile for a wide range of activities. It also enables Bluetooth calling and delivers up to eight days of battery life on a single charge, making it both practical and stylish for daily use.
Xiaomi OpenWear Stereo Pro -
Xiaomi has now introduced the company’s first open-ear headset, the OpenWear Stereo Pro, to global markets, after China’s launch. Designed with a distinctive bionic auricle-inspired shape, the earbuds provide a three-point support system that ensures a secure yet comfortable fit without putting pressure on the ear. The outward-tilted, lightweight design helps evenly distribute pressure, reducing fatigue even during extended use.
For audio performance, Xiaomi highlights the industry’s first five-driver system, which includes a custom 18×13mm loudspeaker that enhances low-frequency sensitivity, paired with a dual driver unit and a piezoelectric ceramic unit to deliver improved high-frequency detail and resolution.
To refine sound quality further, Xiaomi has collaborated with Harman’s Golden Ear team, offering two exclusive “Master Harman” sound modes. The earbuds also support LHDC 5.0 ultra-HD transmission and carry the Hi-Res Audio Wireless gold certification, enabling playback at up to 96kHz for an enhanced listening experience.
Xiaomi Smart Band 10 Glimmer Edition -
Marking a decade of wearable innovation, Xiaomi has unveiled the Smart Band 10 Glimmer Edition, a stylish take on its popular fitness band. The Glimmer Gold model stands out with its premium design, featuring a polished aluminum alloy frame with a high-gloss PVD finish and a metal strap embellished with six sparkling Preciosa glass crystals.
Adding to its versatility, the band can also be worn as a pendant or attached as a bag charm, allowing users to showcase their personal style without compromising on functionality. Beyond the refreshed design, it retains the same features as the standard Band 10, including a 1.72-inch AMOLED display with 1500 nits brightness, HyperOS integration, and up to 21 days of battery life.
