On the audio side, the Xiaomi Open Wear Stereo Pro takes a new approach with its open-ear ergonomic design, built for long listening sessions without discomfort. It offers up to 8.5 hours of playback per charge and 45 hours total with the case, plus fast charging that delivers 2 hours of use in just 10 minutes.

For sound quality, it’s Hi-Res Audio Wireless certified with LDAC, featuring rich bass and crisp detail. It also supports Dimensional Audio, which adjusts with head movement for more immersive listening, along with Harman audio tuning for customizable sound. A leakage-reduction system keeps audio private even in quiet spaces.

Other devices launched include the Xiaomi Smart Band 10 Glimmer Edition and the Xiaomi Smart Camera C701, but the spotlight remains on the Watch S4 and Open Wear Stereo Pro as Xiaomi’s next-gen wearables.
