    My last HK Onyx Mini was fantastic, until it would not longer take a charge. This one uses a more normal charging plug! Its hardly portable though, as it is quite large. Would have liked to have some kind of a battery level indicator besides turning from green to red. Multiple lights like the mini had would be better.

    I very much enjoy this speaker. It allows me to listen to a playlist in any room and not just the room of my main system. I have a small Bose speaker also that i use at times. This sounds just as well or maybe even better. It was a good buy fo me.

    Great speaker when it works. However, after less than a year of use, it will no longer charge and will not work when plugged in. Very disappointed, especially with how much this cost.
