I think it's really good that Wal-Mart stocks Anker products now. I don't know how all that works, why it's taken this long to hit physical stores, but it's all good! Anyway, I'm not sure at all about their bluetooth speakers, but I've tried a lot of their other products, overall the quality is top notch for their battery chargers and cables. Wish I could help more, but there are over 1500 reviews of Anker's speakers on Amazon, averaging 4.5 stars. Can't go wrong there!
