Logitech has me so far never been disappointed, neither with my wireless mouse, my gamepad or with this speaker.
Loading the speakers using the supplied USB cable, for example via the PC. Connection with Bluetooth went smoothly. Device can be attached or hung on a belt. A flyer with pictograms is the complete instruction. More is not found in the package.
The sound is about a 10-Euro-PC speaker par. Thus, I reach for beautiful sound but the sound system and headphones, but Diploma Hunts I dislike miss this useful accessory. With fat bass and generally better sound to me the speakers would prefer. But for starters, the thing is good and worlds better than the much blechenere internal Tablet Speaker.
Since music is rarely for me background music I tend not due to the stunning sounds to three stars as a good PC speaker in the 50 euro range can offer more. But then there again annoying cables, the device would be more difficult, the battery would consider only two hours instead of four etc. Good would rest, removable batteries, but this is a device that will surely soon be replaced by technically better, then it is quite possible even to get over, if you should forget about it at the hotel - what with the small size certainly can happen quickly - where I left only the speaker? And then it is less than a newspaper or shirts - so take good care not to lose sight of him! :-)
About tablet, as well as the speaker can be dosed volume. Bluetooth can be disabled on the device. Furthermore, there is an on-off switch. The device is made in China. Processing seems solid, as is likely to auesserlich wear nothing.
For the Sound 3 stars.
For the overall result, as great accessories on the go without cable and easy to use, I give 3, 4 stars.
