What the REDMI Buds 6 Play Blue is worth

The REDMI Buds 6 Play Blue are Bluetooth 5.4 wireless earbuds weighing 3.6 g per earbud, with a 10 mm driver and IPX4 certification. They deliver 7.5 h of continuous playback, extended to 36 h with the 600 mAh charging case, and a 10 min fast charge provides 3 h of listening time.

Their lightness scores 95/100, well above the market median of 132 g. However, sound quality (47/100) and speakers (45/100) lag behind with a 10 mm driver, compared to market medians of 28 mm and 32 mm respectively.
