And an awsome product costly but worth for it . I bought those speaker 1 and half year ago an it still sound amazing its has bluetooth and nfc helps lot more when you want hear loud and dont wanna go again and again near the spearkes to change the sound or volume , sony is been always been trusted brand and it totally depends on what you’re need if a guitarist or runs a small dance class or for just as a hometheater by connecting it by your television , I had done that for watchin movies
