This mini speaker, though small in size, still offers excellent sound quality. It features a spiral design concept, giving it a strong sense of motion and individuality. The expandable resonant chamber design allows you to gently rotate and open the chamber while playing, immediately increasing the resonance space and enhancing the low-frequency output. When not in use, simply rotate and close the expandable resonant chamber, reducing its size so it easily fits into your pocket. It uses an extendable sound chamber that provides better bass effects, solving the problem of poor deep bass quality often found in mini speakers. The innovatively designed hidden input port gives the product an overall stylish appearance. It also comes with a built-in volume regulator, allowing you to adjust the volume according to your personal preference for greater convenience. This cute, retractable mini speaker is currently available at a retail price of only 88 yuan.
