Amazon = very good The product = very good. Obviously no stereo or sound quality of my living room stereo installation (Yamaha, Triangle). but the cost either. This is a Christmas present for 14 years son, to hear the music from its S Samsung smartphone via a jack / jack cable. Small is easily transported on vacation, the look really much to it, very original. The sound is still ok given the size and cost. A little metal (normal ... Yamaha). What sucks is the dedicated support mono Apple brand! Prompting Apple bought too. The new version is better with bluetooth Ipad and without support, but much more expensive, and we chose to limit waves child too surrounded by various electric waves. Review for a teenager or from family holidays: it is a very good product quality / price ratio.
