With the KEF EGG, you listen wirelessly to HiFi sound. These compact speakers stream music via Bluetooth from your smartphone, tablet, or computer. Thanks to the Bluetooth aptX support, the wireless connection won't be at the expense of sound quality. You don't have to connect the speakers to an amplifier or receiver, because they have an active design. In addition to an AUX input for a wired audio source, the speakers have a number of handy connectors. For example, you can connect them to a TV with an optical cable or connect them directly to a KEF subwoofer. This way, you add powerful bass to the stereo sound image.
