On the back are the on / off switch, the Micro-USB charging socket and a 3.5mm jack. The outer shell of the speaker is made entirely of aluminum, the side boxes of plastic. At the bottom there are three rubber sheets, which prevent slipping on smooth surfaces.
Joining Tablet and speakers via Bluetooth works without problems and the sound is for this small part of truly remarkable and well absolutely space-filling in a 25 m² room. The volume measured with max. 82 dB, both right next to the boxes and 50 cm in front of the front speakers is very compelling.
Without Bluetooth, it works just as well with the included jack cable. Videos I can now enjoy on the inclined tablet in good sound quality.
The instructions included entirely in English, but with such a self-explanatory device you do not need that also.
Of course all other Bluetooth devices or devices with headphone jack such as smart phones, laptops, etc. with the speakers can be connected, but due to its stand function I use it only for Tablet, or Smartphone.
Volume and sound can be to him not regulate that runs over the device.
When fully charged, and medium to maximum volume of the lithium-ion battery keeps good 9 hours.
Conclusion: The speaker with tablet holder is ideal for tablets and smartphones whose owners like it stylish expect a good sound.
