Teufel has unveiled a pair of PC speakers, the Concept B 200. Intriguingly they connect via USB rather than through the typical 3.5mm jack, meaning that they include a sound card and amplifier, allowing the quality to be ramped up above the bog-standard sound devices that are usually found built into motherboards.

It's a 2.0 system, with four 30W power amplifiers in a metal case which supply juice to high and mid-low drivers in each speaker. That USB connection also powers the system, meaning that you won't have to plug them in, either. The amp also includes a USB hub for connecting other devices.

Teufel says that the speakers "offer incredible sonic performance over a USB connection without a sky-high price tag". We'll let you be the judge of that. The Concept B 200 USB speakers cost £184, and are available now.
