Performance Build Quality Comfort Value PRICE $399 AT A GLANCE Plus High-resolution sound Planar magnetic drivers Comes with Apple Lightning and standard cables Minus Little or no isolation from external noise THE VERDICT The Audeze iSine 10’s sound crushes the competition—it’s more dynamically alive, more spacious, and more transparent than any other in-ear headphone I’ve heard so far. With the iSine 10, Audeze completely reinvented the in-ear headphone. I’m not exaggerating. While every other in-ear headphone uses dynamic or balanced armature drivers, the iSine 10 has planar magnetic drivers, the same thin-film driver technology Audeze uses with all of their on-, and very high-end over-the-ear headphones. The driver isn’t the only unique design feature, though. The iSine 10’s wild-looking earpieces are a good deal larger and designed in a completely different way than any other in-ear on the market.
