Shure is adding a new model to its hallowed line of 'buds, the new SE315 Sound Isolating Earphone. The headphones have a single MicroDriver, as opposed to the dual drivers in the SE425 and triple drivers in the SE535, but otherwise is very similar to those family members, including the investment-protecting detachable cables. Oh, and of course the price it a good bit more attractive, with a $200 retail price, while the SE425 and SE535 go for $300 and $500, respectively. Still, attractive enough? We'll leave the handwringing to you.
