The differences are in size, power and autonomy. As you can see from the video, the 320 is much bigger than the 120, it has 240w compared to the 160w that the 120 has and an autonomy of 18 hours compared to 12 hours. At the same time, the 320 has a troller-style handle compared to the 120, which has a simple but effective handle.

@@DJ_Don007 which one would you recommend me to buy?

It depends on what you want to do with it! If you want a more intense party, you can take 320, but I personally love 120, because it is much more practical and useful. And before I was very satisfied with the 110. The 320 is big, powerful but harder to transport even if it has a troller-style mechanism. I say that 120 is nicer and strong enough for parties
