Our take on the Korus V400

by Ralph Graves

Just pass the Baton

Korus V400 wireless portable powered speaker system

The Korus V400 portable powered speaker system makes a great addition to your kitchen, den, or bedroom. It also makes wireless audio just about simple as it can get. You don't have to download an app, program your devices or do anything complicated. Just insert one of the included Korus Baton audio transmitters into your iPhone®, iPod touch®, or iPad® (both 30-pin and Lightning® connector Batons are included). The Baton has all the software necessary to stream audio from your device to the V400. Within seconds, you're enjoying everything you can play on your Apple device with great sound — stored music, Internet radio, game sound effects, video soundtracks, and online music services.

The Baton can stream to as many as four Korus speakers simultaneously. And if your friend wants to share some music from their Apple portable? Just pass a Baton.

The system also comes with a USB Baton, so you can stream directly from your computer to the Korus V400.

Full-bodied sound

The V400 features a stereo pair of high-performance tweeters and woofers angled outward to create an expansive soundstage. The key to the system's robust sound is an innovative acoustic signature called LiveStage™, which projects a multi-dimensional image, placing vocals to the front and accompanying instruments further back in the sound field. You'll enjoy crystal-clear, distortion-free sound at any volume level.

There's plenty to like about the Korus system.
