This is the revised version of 2010 with the following changes: The power supply is much smaller, which is many well-liked. The other change is double-edged: If nothing is output, the amplifier automatically switches off and again when something is to be output. But this is done in the typical Windows sounds too late (is safe with Linux and OS X as well), so that you do not hear the most alerts. That reminds me that do not like, I have to remedied with software. How, can be found in Google Groups under the current date in the group de.comp.os.ms-windows.misc titled "Problem with power-saving speakers". Otherwise, the fact remains that, far removed for the size of fascinating sound of howler cubes. You can use it to build a great-sounding micro system. I do not give 5 stars is because the power saving function can be annoying (on the other hand you can not forget to turn it off, and thus also eliminates the annoyance of the stiff, bad-to-use volume control) and because you can sometimes hear some resonances in the left box. But overall, a clear recommendation!
