Xiaomi has launched a pocket guitar accessory in China designed to turn mobile handsets into portable musical instruments. Built in partnership with the Changba music platform, the magnetic gadget works with the Xiaomi 18 Pro series and Apple iPhone models. It is currently available on JD.com for 599 yuan, which converts to roughly 83 USD.
The accessory comes in black or red. It snaps directly onto the back of a handset using strong magnets. When you are not playing songs, the body folds outward to serve as an angled desktop stand for watching video. The physical layout features 2 separate touch zones for chords and rhythm, allowing users to mimic genuine guitar strumming without needing a full instrument.
Software integration with the Changba karaoke application provides a licensed library of backing music tracks. On the Xiaomi 18 Pro, the gadget can display song chords and lyrics on the rear secondary screen while the user sings. Strumming movements trigger audio output through the phone speakers, letting beginners perform complete tracks without learning complex finger positions.
The device packs a 630mAh battery inside its ultra thin housing. Xiaomi states that a single charge delivers up to 30 days of standard use. This low power draw means players can keep the accessory attached without worrying about frequent recharging cables. The product is aimed directly at casual musicians and mobile vloggers who want a quick way to record acoustic style performances anywhere.
