Shure has released three new pairs of high-end, sound-isolating in-ear headphones, including the single-driver SE315, dual-driver SE425 and triple-driver SE535. The latter two were introduced at this year's CES. The SE315 set has a vented driver and sports a detachable cable that can be formed for a comfortable fit. It ships with isolating tips that can provide as much as 37dB of ambient noise.
