For thos e that want to listen to their favorite Internet radio station without having to be tethered to a computer and an physical Internet connection the allure of new wireless Internet radio devices is quite appealing.  There are several ways to listen to Internet radio without connecting to the Internet via an Ethernet cable or sitting in front of a computer.  Some involve wireless devices such as cell phones, others involve dedicated pieces of hardware that take the form of traditional terrestrial radios.

The Grace Digital GDI-IR2000 Wireless Internet Radio
Perhaps one of the most highly rated Internet radio devices, the IR2000 connects to the Internet through a Wi-Fi connection and connects to any of over 16,000 free streaming audio radio stations.  The IR2000 also provides users with the option of connecting to Sirius Satellite Radio (with subscription) or to the Pandora radio service.  About the size of a small toaster the Grace Digital GDI-IR2000 fits neatly on almost any desktop or nightstand.  Users report that the radio is wonderful for finding new things to listen to, but some users have had slightly difficulties setting it up. 

The iPhone or iPod Touch
The Apple Store currently sells several Internet radio streaming applications that can run on both iPhones and iPod Touch MP3 players.  There are too many apps to list in this article, but the main players all have dedicated applications for the platform.  Pandora is consistently one of the most downloaded free apps in the Store, while other apps such as iHeartRadio also have a strong following.  Be aware that some streaming applications require the iPhone or iPod to be connected via a Wi-Fi connection and may or may not work over the cell phone network's data link.

These are just two of the many ways an Internet radio user can connect and listen to online music wirelessly.  While they are certainly the more popular there are also dozens of other wireless devices available that fit almost any budget and style.
