Shipping and packaging was OK as usual (the DPD driver has not found the doorbell, is not on the consignor or Amazon). The processing of the device 1A, it is very hard, nothing rattles, it acts like manufactured from solid metal. Cutting back there in the design: the antenna is only just off the side mounted, there is no way, to sink them all or to secure at least. The main speakers are admitted without any guard in the front panel.
The device is actually designed as a portable sound box for Bluetooth devices, and one notices also on the execution of the other features: the radio reception is maximum mediocre, and playback options for mp3 files from the SD card or USB flash drive are very rudimentary - there is no written title display, only the number on the card. Ways to move between folders does not exist either. Since I use a Bluetooth device, I can not rate this feature.
All this makes up for the sound of the instrument. Equipped with two 13cm woofers and two Höchtönern is the sound not to be compared with an audiophile Bose system, but the play is very strong pressure and quite detailed. One notices, however, that the main target in the development of young people was that to celebrate a Strandpary. The sound characteristic changes at different volumes. The best sound is achieved with a sophisticated level, the quiet games you absolutely must throttle the bass reproduction.
Another minor drawback - the manual is a joke, but no good.
Conclusion: great sound with a few drawbacks, so three stars.
Update after two days of operation: the above things are still out, but I am very begeitert of how long the device on battery power plays (now a total of almost 4 hours and with quite elevated volume).
