I bought the Zik2 after a very positive experience with the Zik1. The big advantage of 2 is weight. The drawbacks for me are: The sound is not the same, less finesse that can be corrected through the application itself but lacks simplicity. The classic equalizer disappeared what a pity! Inconvenience also, I had bought the holster and battery because no one accessory is compatible with the 2 ... Another problem in my case the touch is much less accurate because of the helmet liner. I am disappointed that Parrot can not do at least as well as Zik1 with yet more experience than the first release.
