The Bluetooth speaker market might be crowded, but there's always extra room for more competition, especially when it comes in at a cool $59 (£68.39, AU$79). With the Dell Bluetooth Portable Speaker - AD211, it may not be eye-catching, but its low price tag sure is. And at that, it's impressively well-stocked with features and a satisfactory sound. Compared to more expensive and similarly-sized options like the Harman/Kardon Esquire Mini and the JBL Charge 2, the unimaginatively-named AD211 holds its own as a capable speaker, offering many of the features seen in the competition for less hefty of an investment. But how does it sound?DesignWith the AD211, Dell's choice to play it safe in its design isn't an oversight. The grey, energy drink-sized speaker canister is purposefully plain, matching the (rather appealing, if I do say so) aesthetic of Dell's office-friendly products. The biggest stride it makes in design is keeping it simple, which allows its functions to benefit from its form. For a bargain, the materials and design offer a basic, yet effective presentation.The speaker's design is conventional but tuned to be highly usable, no matter which of its two modes of orientation you utilize. If you choose to stand it upright, its bottom side rests on a stable, rubberized plate that hushes buzzing created by strong bass.
