I LOVE Muzen. Like LOVE LOVE. I have two of their speakers, metal and wood. Use them all the time, travel with them, enjoy them indoors and out. But this product was really meh.
Tobie S.
I was pleasantly surprised by the product. At first I didn't think it worked so I sent it back then. The company sent me a new one so I could try it out and found out. I was doing something wrong. They are very kind, very thoughtful, very helpful.
