A few years ago they released an MP3 player based on Soundwave, but personally I wish they offered a stereo system based on his Autobot counterpart, Blaster. He would just look at home on the bookshelf or entertainment unit.
It doesn’t even have to be an official product, just the basic shape and colors, and fans could add their own Autobot insignia.
Cassettes are pretty much dead, so a cassette-like display would be fun. Standard features like a CD player, Bluetooth, and iPod dock could also be included. I’d probably include an remote that looked like a cassette.
