Xiaomi Sound Pocket

Xiaomi Sound Pocket: 200g Pocketable Form Factor & 5W Passive-Radiator Acoustics

The Xiaomi Sound Pocket (official model MDZ-37-DB) is an ultra-compact portable Bluetooth speaker weighing approximately 200 g and measuring just 90.8 × 74.4 × 42.6 mm—small enough to slip into a jacket pocket or clip onto a backpack strap using its integrated flexible rubber lanyard. Despite its palm-sized footprint, Xiaomi engineers an acoustic chamber combining a 5W rated full-range speaker driver with a large-area subwoofer passive radiator and automatic dynamic tuning across a 100 Hz to 20 kHz frequency response (≥70 dB SNR). The speaker can stand upright or lie flat on a desk to project clear podcasts, study audio, and everyday music.

IP67 Weatherproofing, Bluetooth 5.4 TWS Stereo & 10-Hour Battery Endurance

Sealed to an IP67 dustproof and waterproof standard, the Sound Pocket shrugs off sudden rain showers, beach sand, and kitchen splashes. Its Bluetooth 5.4 wireless connection provides stable pairing up to 25 meters in open environments and supports True Wireless Stereo (TWS) linking—allowing two Xiaomi Sound Pocket units to pair automatically as left and right stereo channels. An internal 1000 mAh (3.7V) lithium-ion battery delivers up to 10 hours of playback at 40% volume and recharges in roughly 3 hours via a 5V 1A USB Type-C connection, while a built-in microphone supports one-press hands-free voice calls.
