Verdict

The Xiaomi Mi Bluetooth Speaker MDZ-15-DB is a highly portable aluminum-clad speaker featuring dual 36mm drivers with a total maximum output power of 6W (2x 3W) and a frequency response of 85Hz to 20KHz. Operating on Bluetooth 4.0, it features a built-in microphone for hands-free calling, a 3.5mm AUX input, and a 1500mAh battery that charges via micro-USB in 2.5 hours to provide up to 8 hours of playback time. Its main advantages include a lightweight 270g frame, an integrated battery level indicator, micro-SD card playback support, and distortion-free audio even at higher volumes. However, notable drawbacks include its outdated Bluetooth 4.0 standard, lack of water and dust resistance certifications, limited low-frequency bass extension, and the exclusion of basic charging or AUX cables from the retail packaging.
