This is a brand new in box G200 portable wireless speaker that doubles as a phone stand. It has a built-in magnet on the bottom, so it will stick to the back of an iPhone or any MagSafe-style case. You can use it to prop up your phone to watch videos & get better (or at least louder) sound than standard phone speakers. You don’t need any special cables for it either, you can just use your phone charger to power it up. It’s small enough to be very portable, you could literally just carry it around in your pocket if you wanted.
