The Xiaomi Portable Bluetooth Speaker has a compact rectangular form factor measuring 154 mm wide, 56 mm tall, and 25.4 mm thick, with a total volume of 219.05 cm³ and a weight of 249 g. It carries an IP66 rating, meaning it is protected against dust ingress and high-pressure water jets, placing it firmly in the water-resistant category. The unit houses two 40 mm drivers and includes a control panel directly on the device for straightforward operation. It does not feature a neodymium magnet, touch screen, RGB lighting, remote control, or a neckband design, and no travel bag is included in the box.
The speaker covers a frequency range of 20 Hz to 20,000 Hz and includes a passive radiator to support low-end reproduction without a dedicated subwoofer. It operates as a mono speaker, as stereo output is not supported. A single built-in microphone is present, though it does not offer noise cancellation. Magnetic shielding is not featured in this unit.
The speaker is powered by a built-in 1,980 mAh rechargeable battery rated for up to 10 hours of playback, and a battery level indicator lets users keep track of remaining charge at a glance. The battery is not removable, and wireless charging is not supported, so the unit relies on a wired connection for recharging.
Wireless audio is handled via Bluetooth 5.4 with a maximum range of 10 m, and the speaker supports NFC pairing for quick device connections. The single USB Type-C port serves as the charging interface, while there is no 3.5 mm audio jack, AUX input, 3.5 mm male connector, external memory slot, microphone input, Wi-Fi, Ethernet, or DLNA support. Advanced Bluetooth audio codecs — including aptX, aptX HD, aptX Adaptive, aptX Lossless, aptX Low Latency, LDAC, and AAC — are not supported, and the unit does not feature AirPlay, Chromecast, Auracast, or Bluetooth LE Audio.
The speaker can be used wirelessly and supports smartphone remote control, allowing playback management from a paired device. It includes 4 GB of internal storage for local audio files, along with a sleep timer and voice prompts for audio feedback during use. Fast pairing, voice commands, a mute function, radio, and power bank functionality are not available on this unit.
The speaker supports stereo pairing, allowing two compatible units to be linked together for stereo sound playback.
