Got the Box bought, so I can hear anywhere in my apartment 74qm music and my girlfriend not disturbing. What can I say, the Bluetooth reception is optimal in the whole house, the connection with my Samsung G SII works without problems and I hear almost daily about Spotify music on this optimum box. The bass is round and I have nothing to complain about in the rendering of my music genre (metal, rock, hip-hop). Thought to myself, I take some money in my hand and I was not disappointed. I can only recommend this product !!!! Top! Top! Top!
