Magaosi is a Chinese brand that produces iems. They started out with the K3 and has since improved it to the K3 HD. Recently, they have released the K5, X3 and Y3. I would like to thank Penon Audio and Magaosi for the review unit of X3. The X3 is available on Penon Audio .

Unboxing & Accessories

The X3 comes in a black package with protective cover that sports the brand name, model name and description of the iem. At the back of the protective cover, there are specifications of the X3. The black package has a transparent film that shows the iem. After opening the package, there are the iem, MMCX cable, Bluetooth MMCX cable, micro USB cable, user manuals and semi-hard carrying case which contains packs of tips.
