What the Xiaomi OpenWear Stereo Pro Sand is worth

The Xiaomi OpenWear Stereo Pro are open-ear earbuds with ear-hook design, weighing only 9.7 g per earbud versus a market median of 132 g. Their open architecture features an 18 x 13 mm driver, dual Hi-Fi balanced armatures, a ceramic piezoelectric tweeter and a 10 mm speaker for active sound leakage reduction.

Bluetooth 5.4 connectivity ensures recent wireless technology (90/100 score), supporting AAC, SBC and LDAC codecs, with 10 m range and dual-device connection. Battery life reaches 8.5 h continuous playback, 45 h with the charging case (700 mAh), and fast charging provides extended use after 10 minutes. IP54 rating protects against dust and water splashes.

With a 93/100 overall score and 95/100 lightness rating, these earbuds sit in the 100 to 280 euro range, delivering active noise reduction, refined build and wireless endurance. They suit users seeking open design, extended comfort and advanced features (touch controls, audio recording, AI subtitles, spatial sound).
