I was looking at this Bluetooth speaker of mine and realized that I use it a lot and there's so much I wish I could do with it that I'm currently unable to. 

I redesigned what a portable speaker essentially is used and thought about most of the things you could do with one. 

Instead of doing a regular one, this is a limited edition with a fully customizable exterior from the color, material, textures and themes. I want this speaker to be very simple. That's why there's no fancy lights, no unnecessary details, everything on it is functional. 

The personalization comes in here, you can customize every external detail of the speaker including the software which has a number of settings and themes. 

That becomes your signature. It's called Signature as it is supposed to speak for you/represent you.
