Shure knows their stuff when it comes to making earphones, so we're pretty excited about their new line. The new Shure Sound Isolating Earphones line consists of four new models, across different price ranges. The SE210 ($150) features a single hi-def MicroSpeaker and a deluxe fit kit, while the SE310 ($250) couples a MicroSpeaker with BassPort technology to provide richer full-range audio. The SE420 ($350) features dual TruAcoustic MicroSpeakers as a dedicated tweeter and woofer to provide more accurate music reproduction. Finally, the E500 receives a slight cosmetic change as it becomes the SE530 ($450), the flagship of the line with triple TruAcoustic MicroSpeakers.
Working out to music gets a little better with the Sennheiser MX75 Sport headphones ($50), which offer a twist on traditional design via their "Twist-to-Fit" system for a more secure ear fit. They're moisture-resistant, have a cool looking neon green profile and sport powerful neodymium magnets for better sound. They also come with an ear adapter set.
