I bought this 2 weeks ago and found that it works really well. Im glad the device can turn itself off after some time of not being used (because sometimes i just don't want to go across the room to turn it off). I'll have to look into it, but it would be nice if it paired with an app and had additional features, like controlling the volume on the device remotely.
I bought this as a birthday gift for my son and he loves it the only thing I don't like about it is that you have to power it off from the speaker or the connected phone there is no parent phone control option because the music goes well on into the night
Sound quality is good. Excellent clarity and powerful base considering its size. But I noticed that it has no microphone. After purchasing I found this surprising lack while trying to connect the speaker to conference calls. How can a bluetooth speaker of such spec come without such a basic feature! I wonder!
