A:AnswerNo and I have tried. I looked for an equalizer as well in the apps but there is no way that I have found to adjust the highs and lows which is why I gave it a4 star instead of 5. The sound is loud and very clear but sometimes you want the bass not to stand out so much
A:AnswerWhat was the power output from your charger? The Flex requires at least a 5V 1.5A charger from what I've read.
I would try using at least a 2A charger with a new cord before sending it in. If the same issue still persists after this and this is a new unit, return it.
A:AnswerWe had played it for over 10 hours one day at a BBQ and-it still had charge remaining. It mentions up to 12 hours on a single charge and I have no doubt that we could have played it a lot longer.
