This is an interesting little device. Made by Kerchoonz, the K-box allows you to listen to music external speakers as it turns any surface you set it on into an audio output device.
So, you just plug your iPod into the K-box using the 3.5mm audio jack and set it on a solid surface. As soon as you press play, the surface will resonate with sound and you’ll get to hear the music just like that.
It uses something called Gel Audio Technology to change surfaces into speakers. Interesting idea, and might just be worth checking out. It’s small, about as big as a phone and recharges via USB for up to 20 hours of playback. You can get the K-box now for $74.50.
