A:Answer Great question! The newest model (which is the one I purchased) has a better battery life, it can now be charged with any microUSB cable (you can only charge the older model with the Bose cable), it has a built-in microphone so you can use it as a speakerphone, you can play/pause/skip songs using the new button on the top of the speaker, and it provides you with audio feedback (for example it talks to you when your device is connected). I like the newer model much better than the previous one, but that's just my opinion. Hope this helps!
