Multifunctional BT speakers with many passing opportunities, long duration and a very good sound.

The included Quick Start Guide is available in German, English and an Asian language.

The speaker is 24cm wide, 6cm high and 5.5cm deep and weighs 439 grams.
He is barely suitable for mobile applications (eg in the swimming pool, vacation, school etc.).

The surface of black (and fortunately) matte plastic is very velvety / soft.

The control buttons are well structured placed on top.
There you will find the keys for play / pause / answer, loud / quiet & skip buttons / Skip +, the microphone, the clock button, the radio button and the button for Bluetooth operation.
Skipping and Lautstärekregelung are therefore not separated from each other, what I always something frimmelig personally find the service here.

Volume changes are not signaled by a confirmation tone as with many other speakers in this way. Good!
Bad is against the fact that the Speaker, the last volume does not notice and starts over again at level 10.

A 3.5 mm jack input is also on the back as the micro-USB charging port, a microSD slot and a USB input A for USB sticks. Thus, the device has almost all the usual ways of playback devices.
Also, the on / off slider is housed on the back.

On the front are located behind a protective metal grid the stereo speakers and a small subwoofer.
In the central upper part a light blue LED display is integrated, indicating the Bluetooth mode, radio frequency, time, volume or the selected track of the micro-SD card or USB stick.

The radio works surprisingly well.
This even without an infected microUSB cable, which is in other BT speakers often requires an additional antenna.
The radio receiver is thus settled well above the average.
By pressing the FM button you can perform an automatic channel search.
Too bad I find, however, that you can not sort the channels or delete according to his taste.

The integration of a clock integrated with an alarm function, I find a great idea.
You can even make music by the wake micro SD card or a USB flash drive.
As file systems for storage media are unfortunately only accepts FAT32 and exFAT, NTFS is not readable.
Ebebso shame as the lack of an ID3 tag display and a shuffle mode.

Pairing (Pairing) with the desired Bluetooth device such as a smartphone or tablet works simple.
Simply start the speaker and then manually activate Bluetooth on the smartphone / tablet.
The speaker is then found in the device list as "SDY019" and connected.
After a successful pairing, the connection is saved and is automatically produced at the next start.
NFC for an even faster connection provides the speaker not to.

The sound quality of the speaker is really very good.
Voices and instruments and basses are presented very clean and accentuated.
Even at high volumes, and even at the maximum volume (level 16), the sound distorted at all practical.
About the quality Bluetooth audio technology aptX the speaker does not have, unfortunately, with which one can obtain a considerably clearer sound in my experience if the player device supports it (like my Grade 3 and S5).

In live 7-8 meter range are possible, then there will be interference and crashes.
Across rooms are equipped with an intermediate wall 5-6 meters in it.
These are similar good results as I have found in other high-quality BT-speakers in the price range.
The above 10-20 meters are utter nonsense, something no me known Bluetooth device.

The integrated speakerphone works very neatly.
In both directions a conversation without difficulty.
This is not just a feature-gimmick, but an actually usable and meaningful function.
Needless I find, however, the English announcement of the number that would have been better able to integrate the display.

The mentioned in the product description runtime of 6 hours I have already exceeded by 2-3 hours. And he runs and runs and ....
That surprised me very positively.

With a maximum input current of 1A are good 3-4 hours required for a full refueling of 1,500 mAh battery.
Thus, the input current is probably in good 430-480mAh (power loss included in the calculation).
Contrary to statements in the manual, the device can load / run in the on-state.

So I can recommend in the overall consideration the DBPower BX-100.
He is very well made, has many passing opportunities and a very good sound.
While it lacks some features such as aptX and NFC, but the functionality is enormous.
Here, since the price-performance ratio fits I like to give the deserved 5 stars.

I hope this review could assist you in your buying decision ...
