I hope they fixed the battery life and connectivity issues of the previous KZ wireless stuff.
Hope so too. my KZ Z1 lasts a whopping 40mins before powering off now (it's only 1 side that's draining that fast though, the other side can probably go on for a short while) this is after about 4 months of use and down from the initial 2hrs of battery life. lol ¯\_(ツ)_/¯
