A sound ball!

About the size of a big ball, this Bluetooth speaker is a use can not be simpler. A jack for charging (or connect a wired audio source, if you do not have Bluetooth), 3 buttons, and go.

With a load of 3-4 hours, you will in normal use 12 to 15 hours of battery life (of course, it depends on the volume and distance with your Bluetooth device).

I use 2 different Acer smartphones and Samsung Galaxy tablet, without any problems. The GOgroove OR3 is recognized immediately by the devices.

A button is used to turn on / off the ball (long press), start the Bluetooth search (short press) or to redial the last phone number called by phone (double pressure).
Loses the + button to increase the volume (long press) or change the play track (short press). Ditto for the - button.
Of course, the volume is also adjustable from the source device. Similarly, SDRs my smartphone settings allow you to change the Treble / Bass on GOgroove OR3.

Let's talk about the sound quality, exactly.
Despite its small size, GOgroove renders well enough bass. Of course the power is limited (3W), but it is enough for an extra use in a bathroom, bedroom, kitchen ... A very simple way to move his music all over the house, in having to connect anything.
The Bluetooth signal is received over a distance sufficient to cover a house (not if you have lead walls, I imagine.

The design of the object is rather successful. A black sphere with a metallic blue liserai. Simple, sober, not intrusive.

In summary, I am very satisfied with this mobile speaker, very practical, very simple to use, and provides a sound quality very respectable for an object of this size.
