The Piranha comes in a usual Razer styled box with a lot of text on it. On the back you can read all about the specifications of the headset and all of the features it has. In usual Razer style the Piranha is endorsed by a lot of pro gamers. I would not read much in to this because they are after all paid by Razer to make those comments.
As with most Razer stuff you get a couple of flyers and some manuals. You also get some stickers with the headset which of course is of the Razer three-headed snake logo.
