Pros: Durable design, Improved sound quality, Single driver, Includes the Shure Fit Kit, User-replaceable cable
Cons: No more split cable, Expensive, Not very comfortable
Review: Better overall design and a single High-Definition MicroDriver make the Shure SE315 a worthwhile upgrade over the SE310 or the SE215. As far as comfort is concerned, this may not be the best as the style of the earbuds, requiring the cable to be looped over the top of the ear, is a little odd and awkward, but coming in with the Premium Fit Kit which includes three sizes (S, M, L) of the flex and black foam sleeves and a pair of triple flange and a pair of universal fit yellow foam sleeves, you'll find it sitting nicely on your ears after a few attempts. Sound quality is greatly improved as opposed to cheap earbuds which are somewhat lacking in depth or those that produce too much bass, making your music sound a little distorted. Sound isolation is also very good, as expected, allowing you to avoid distractions by blocking up to 37 dB of external noise. We all know that accidents happen when you have a busy lifestyle and there's nothing more annoying than throwing away expensive earbuds just because the cord got jostled and you're already out of warranty. With the Shure SE315, you can extend the life of your earbuds through its detachable and fully replaceable cable. Not having the same split design as the older models is a significant gripe. Still, it's better than not getting your hands on a replaceable cable at all. Cord length is also longer than we would've liked, at exactly 64". Bottomline, if you're committed to splurging a bit and you're tired of the average sound of your cheap earphones, the Shure SE315 will give your ears a treat. It can be purchased in clear and solid glossy black and is compatible with the Shure CBL-M-+K Music Phone Cable with Remote + Mic for iPhone, iPod and iPad which is very nice to have but will definitely add cost to the already-expensive price of the earbuds.
