I own both hydra-x & hydra-x+. Yes, they sounded different. I would say the former has better tonality on vocal while the latter has more transparency, power and punchier bass.   If anyone have read the review on 6moon probablly knew that they have replaced it with different brand of battery...

Can anyone modify the luckit driver so it will work on windows 8? Currently i can only use it in win7 Thanks
