Acoustic Research has just announced two new Internet radios that will have plenty of unique features without the hassle of a PC tether. The two models, the AR Infinite Radio 200 and 600i will both have Wi-Fi connectivity, AM/FM radio stations, and 512MB storage memory.

Without the need to directly connect to the Internet, users can now bring online radio to other areas of the home. However, you can still use the USB and Ethernet connections if Wi-Fi is not available. Listeners can customize their stations with the Infinite Radio as well as save favorite URLs through the Personal Portal Feature.

6″ />RCA introduced three new devices last week. One of them is the a Portable Media Player called the Lyra Slider, the other is the Small Wonder EZ300HD camcorder, and the last is the Wi-Fi capable Infinite Radio.

The Lyra Slider, which sounds like a Tomb Raider character, is a black and chrome Portable Media Player that resembles a slider phone. Not only can it do the usual video and audio files, but is set up for FM radio and voice recording. It will come in 4GB and 8GB.

Check out the rest of RCA’s offerings after the break.
