The housing is made of light gray plastic with a wrong sitting sheet grid - both with some chromatic aberration. While this does not affect the function, but disrupts the visual appearance. On the back are three inputs for mini USB, Micro SD card and audio cable. The three feet are sufficiently non-slip, and above you can still find two switches for on / off and volume. The whole thing gets certainly no prize for "innovative design", but is functional and certainly not ugly.
When charging the battery via USB lights two red LEDs in the control knobs, unfortunately the manual does not say anything. When the battery is fully charged, it switches off and the light goes out. This comes in handy when you load a PowerBank like me.
After turning on the speaker - why the button calculated must be 2 seconds or more, probably remains a mystery of the designer - you hear a tone, the well should be a Bluetooth signal. Anyway, you can select the speaker (LONGQG) a smartphone now and you have immediate full control of the program. At the loudspeaker itself is only the volume and forward / backward adjustable.
In playback mode, blue LED indicators light up instead of red when charging. It takes some time until the speaker noted, if there is no Bluetooth is announced. At first I thought: "Was it that?" - But then came in direct connection to the PC still music. The sound is much better than that from my screen - and even louder. Stereo is naturally at a width of about 25cm virtually impossible - but my wife grumbles not when I listen to music on the PC. This clearly speaks for the sound quality. Here missing basses are often criticized. I am surprised, however, how much of this bass speaker provides without the plastic casing clatters.
Conclusion:
Most disturbs me the oblique grating - it costs a star deduction. If you "not helpful" find this review, please post a comment. This helps other buyers much more than meaningless "unchecking"!
