When I first heard the built in speaker, I thought, "hmm, that sounds better than I thought, about as good as my Oontz". Then I plugged it into my Oontz and it was like, "nope, not even close". But no one in the family is much of an audiophile, and my wife has low tolerance for loud music anyway. I wish I had picked up the Anker for $27, but I need to calm down on the spending so I'm content to wait for something to fall into my lap. Set up the bedroom unit as an alarm clock for tomorrow morning, we'll see how that goes. The only annoying thing is my kids keep interrupting my music with Simon Says commands and picking their songs. Let the old man listen to his U2 in peace!
