A cube that has a 1" x 1" x 1" small size.

Today while visiting my son and his family he said, "catch" then threw a little cube that I caught. It had a bright little blue LED glowing. Then it began to play music! Amazing. It was a little Bluetooth receiver, audio power amplifier, rechargeable battery and little speaker. My 2 years old grandson likes dancing with it.

I had a Wowwee One some years, which I gave to my stepdaughter:

It was fun attaching it to different things and hearing the difference - a large window produced quite a lot of bass.

I asked my son where he got the tiny speaker and he said it was the last one in a store, it is no longer available. I forgot to tell you guys that it says, "Low Baddree" with an English lady's accent.
My son forgot to tell me that it has a microphone and works as a speakerphone when linked to a smart phone. When you speak the smart phone can convert it into text.

In a video a guy opened its package that said it has a camera but it does not have a camera. My son said it controls the shutter of his phone's camera. Here is the link:
