Ok so I got this speaker which had big 4/5 star reviews and everyone loved it but there are 2 issues here: 1) when I connect it to my tv, although the sound works, for some reason the sound seems disconnected from the picture, its in sync, but something is off. Do you know why this happens? Is it because 1 speaker is not in stereo mode?! 2)The sound seems like its from a cave. Its not like an echo, it sounds more like a towel-covered speaker. my iphone 6 speakers sounds a lot different, and I doubt my iphone's speakers are better than this dedicated device. I am not sure what it is, everyone gave great reviews to the sound. Do you know what is going on here?
