Surprisingly big sound from a tiny box is what you can expect from the Bluetooth-enabled ClarityHD Micro Speaker Monster introduced at CEDIA Expo. The concept: Instead of suffering through the tinny sound you get from your smartphone, tablet or PC, stream the audio to a portable speaker that easily fits in a briefcase or backpack.

CSR’s aptX audio coding is employed to deliver CD-quality sound and functions such as playing music, answering calls and Bluetooth pairing are handled by simple voice commands. Operating range is 30 feet and the speaker’s lithium-ion battery is said to last 5 hours on a single charge. Available in black and white, the ClarityHD sells for $220 and has a minijack input for use with non-Bluetooth devices.
