As the song goes, if you like your smartphone you should put a ring on it. In a sense, ORII does that, but in the opposite direction. It practically puts your smartphone in a ring that, in turn, you do put on your finger. But this is no Bluetooth controller for your smartphone. This is, instead, a Bluetooth “headset” you wear on your finger that lets you take and make calls by simply placing your finger on your ear. And, yes, you’ll look crazy while doing so.
