Libratone (www.libratone.com) has announced the Libratone Zipp, a portable, battery-powered, wireless speaker that works with Apple's AirPlay without the need for a Wi-Fi network and complicated setup.

A full charge purportedly provides up to eight hours of playtime wired and up to four hours using the wireless connection. The Libratone Zipp features changeable wool covers in eight colors. It works with the iPad, iPhone, iPod touch and Mac, as well as a PC.

Developed especially for Libratone Zipp, PlayDirect technology makes it possible to stream music with or without the need for an in-home Wi-Fi network, says Tommy Andersen, CEO of Libratone. This Libratone-only feature is an easy-to-use, ideal solution for picnics, camping trips and other outdoor activities, he adds.

PlayDirect works in conjunction with AirPlay technology, creating a direct Wi-Fi connection between the Libratone Zipp and any compatible device, such as an iPhone, iPod touch, iPad, or computer. The slick Libratone Zipp offers a contemporary design with a Scandinavian heritage and a rainbow color selection, including Salty Grey, Pepper Black, Pineapple Yellow, Raspberry Red, Passion Pink, Plum Purple, Petrol Blue and Icy Blue.

Libratone's Italian wool covers are sold separately. Additionally, the minimalistic speaker features a leather handle for portability. The Libratone Zipp will be available next month for US$449.
