Idea for portable sound

[akis]

I was looking to buy portable speakers for my laptop so I can enhance the weak sound. My ideal would be:

1) round or square and fits in the palm of your hand like a cricket ball
2) you twist it off and it becomes two pieces, stereo speakers
3) connects via USB and/or bluetooth to your laptop but only one wire, not cool to have to deal with two wires getting tangled up and difficult to fold back when you want to close it
4) very good quality sound

Apparently, by reading the reviews on Amazon, such a product does not yet exist.

Pick one.

Apparently,...such a product does not yet exist.

It takes physical SIZE to move air at low frequencies.  As SirNick indicated, your requirements #1 and #4 are mutually exclusive.
And don't hold your breath. That's one of the laws of acoustic physics that I don't expect we will be able to break.
