The UGREEN US211 is a compact adapter that lets you connect your favorite 3.5mm wired headphones or audio cables to Apple devices featuring a Lightning port. Because it is Apple MFi Certified, you can trust that it will work reliably with your iPhone, iPad, or iPod without compatibility issues. Built for durability, the adapter features an aluminum alloy shell and a nylon braided cable that resists tangling and wear during daily use. It measures 10 cm in length, extending to 12 cm including the connectors, which provides a bit of flexibility so your headphones don't pull directly against the device port. Beyond simple audio playback, this gray accessory supports volume adjustment and microphone functionality, allowing you to take calls or change tracks without needing to touch your phone.
