Superior sound, little package. That’s what Bose promises with its Soundlink. The diminutive system is wireless, allowing your tech-savvy kid to stream tunes from any mobile device via Bluetooth—without a dock or extra cords. And at five inches tall and weighing just over two pounds, it can go wherever your kid goes—but not to class, of course. Best of all, it sounds more like a high-end sound system and less like a portable speaker.
