Summary: The Block Rocker Explorer Sound System IPA56B I purchased did not come in it's original packaging. There are two units available through this dealer at Amazon with the same exact model number IPA56B --one with a battery which stays charged for up to 50 hours and another (upgraded battery version--which I purchased) that holds a charge for up to 75 hours. There is no way of knowing which unit you will actually get, because it comes in a plain brown box.
Summary: Ugh! So I really REALLY wanted to keep this speaker, but I definitely noticed output distortion at times which was very annoying. My Samsung S2 & galaxy note 10.1 tablet connected instantly whenever I tried to pair them, and Pandora would stream superbly....until the distortion. I did not notice it at first, but since I was planning on adding this unit to my rental rotation, I wanted to make sure there were no problems.
Summary: Speaker is fine, but no tone control. Blue tooth works well. Battery life is good. One "down" is the microphone did not work. Manufacturer said they would replace microphone....but would not ship to FPO (military) address. So I had to have the replacement microphone shipped to my brother, then pay to have him reship it to my FPO address. Also, the day after I bought it for $221, Amazon dropped the price to $179. Just bad timing on my part.
