Of almost all gadgets, earbuds have the least surface area to work with, which means external design innovations are often incremental and minute. Color and style are the most noticeable physical characteristics that manufacturers tweak, but neither has an effect on the performance of an earphone. So, what's a new company to do in order to stand out? Make an earbud with an innovative design that influences sound quality. That's precisely what Amazing Tech Products has done with the Purebuds earphones, a $50 product with uniquely shaped eartips that affect audio output. Add to that some internal technology that purports to protect your hearing, and you've got a pretty intriguing set of earphones.
On first glance, the Purebuds earphones don't look that different from your standard iPod earbuds. Two round, white discs contain each miniature speaker, and a 45-inch white cable descends to a 3.5mm L-plug. Unlike most stock earbuds, these 'phones feature an uneven Y cable meant to be worn behind the neck, which may or may not appeal to you. Also, rather than chintzy foam sleeves, the Purebuds include three sets of silicone tips, each in a different shape. The varied design is meant to offer diverse sound profiles. There's a flat, donut-shaped sleeve to simulate surround sound; a double-flange-style tip for bass boosting; and a narrowing, contoured fitting that offers more general or full-range sound.
