This is an oBravo genuine ob-MMCX cable and three types of replacement plugs (2.5mm, 3.5mm, 4.4mm). It is compatible with standard MMCX, so it can be used with products other than oBravo. The build quality is quite rough, but that's how this product is. The playback device side is detachable, and you can swap between three types of plugs: 2.5mm, 3.5mm, and 4.4mm. The plugs are in good condition, but the cable itself has some fraying in places.
