Zooka 

iPads are great for playing games and music on but unfortunately they don’t quite have the volume that laptops do and can often get drowned out by background noise. All that can be a thing of the past now with Zooka, a lightweight speaker bar that slips right onto your ipad. It is small, sleek and stylish and very portable. They are currently not for sale but is a project on kickstarter but has more than doubled it’s goal and there’s still over a week left in which they have to reach it so I think it’s safe to say you can expect to see it for sale soon!
