The Pocket Guitar accessory attaches to the back of Xiaomi 18 Pro and 18 Pro Max smartphones using magnets. When folded, the device covers the secondary display. Once opened, it splits into two sections: one features chord buttons labeled I through VII, while the other mimics strings with a textured surface.
The device connects via Bluetooth and integrates with the Changba karaoke app. In Chord mode, users select chords with one hand and strum with the other. In Rhythm mode, the app handles chord selection, requiring the user only to follow the beat. The secondary screen displays controls and information during gameplay.
Compatibility extends to other Xiaomi models and iPhones running iOS 14 or later, provided they use the Changba app. The accessory includes a 630 mAh battery, which the manufacturer claims lasts up to 30 days on a single charge. It features a USB-C port for power.
The product is currently available for purchase in China. The retail price is set at ¥599, which is approximately $90.
