FiiO SK-JM21 – Official Protective Leatherette Case for FiiO JM21 Portable Music Player The FiiO SK-JM21 is the official protective leatherette case designed exclusively for the FiiO JM21 portable music player. Crafted from eco-friendly PU leatherette, the SK-JM21 case delivers a luxurious soft-touch feel combined with reliable everyday protection — keeping your JM21 DAP safe from scratches, dust, dirt, and minor impacts without adding unnecessary bulk. Whether you carry your FiiO JM21 in a pocket, bag, or backpack, the SK-JM21 protective case ensures your device always looks and feels premium. The SK-JM21 leatherette case is custom-designed for a perfect fit around the FiiO JM21, precisely wrapping around every contour of the device. All ports, buttons, and headphone jacks remain fully accessible at all times — no need to remove the case during use. The case is also fully compatible with both the factory-installed PET protective film and the separately available tempered glass screen protector, meaning your JM21 remains protected from every angle. Premium construction details make the SK-JM21 stand apart from generic cases. An inner steel ring support structure provides extra rigidity and shape retention, ensuring the case never deforms or loses its form over time. The button areas feature hot-melt protrusion positioning — precisely aligned raised points that deliver clear, accurate, and comfortable button feedback through the case, so you never miss a press. The Velcro closure design at the top keeps the JM21 securely inside during transit while making it effortless to insert and remove the device, and easier to plug and unplug headphone cables without fumbling. Available in Dark Blue and Black, the FiiO SK-JM21 protective leatherette case is the essential accessory for every FiiO JM21 owner who wants to protect their investment while maintaining the elegant, minimalist aesthetic that defines the FiiO product family.
