Question: what is the difference between fire stick and fire cube?
Answer: Audio Support. FireStick 2nd Gen supports Dolby Audio, which limits the surround sound to 5.1. On the other hand, FireStick 4K and Fire TV Cube support a much superior Dolby Atmos technology with 7.1 surround sound. You won't notice a lot of difference if your audio output is just the speakers of your TV.
