The amazingly powerful sound of the speaker has already been described many times and rightly so. And quite versatile in the choice of the source, the device is: It plays MP3 files from an inserted microSD card, music via Line-In, for example, from the mobile phone and also works via USB cable as USB speakers to the computer. This works on multiple computers with me very well and immediately after connecting the Lasmex, unfortunately just not the latest laptop with Windows 7 64 bit and USB 3.0 ports (the actual target device). On Windows XP and Linux (Ubuntu 64-bit) sound drowned out almost immediately after connecting the USB cable from the cube. On HP laptop speaker remains silent (except for a faint background noise), although Win7 recognize a USB speaker (AC209N) and also allows access to the memory card.
Whether the problem is on the computer to the operating system or the user, I can not say, despite several attempts. Nevertheless, I forgive only 4 stars because the most important for me ability of Lasmex S-01, the road to act as a mobile USB speakers also on the laptop, is not available.
