Sound amazing for a portable speaker of this size. WHAT HIFI announced it, I confirm. Of course, do not expect to find the deep bass of your living room or your speaker cabinet. But down there with HP of this size and in this volume demonstrates a great mastery of the product. The highs are crisp, and present without being aggressive. We distinguish between instruments easily rank second. The mediums are clear and making the resulting natural voice and rather faithful. Low course a little would be welcome. But they are present and dynamic. A top in its genre!
