The SE215 earphones use dynamic MicroDrivers for clear audio with extended bass response. They feature a detachable cable with formable wires that fit over the ears to stay out of the way whether you're listening on stage or at home. Plus, the cable is reinforced with Kevlar for lasting durability. The Shure RMCE Remote & Microphone Cable transforms your SE215 detachable headphones into a mobile stereo headset for use with your iPhone, iPod, or iPad. The cable has an integrated microphone for clear vocal pickup, plus a 3-button remote for answering and ending calls, controlling media playback and adjusting volume levels. The standard 3.5mm plug provides compatibility with a variety of portable devices. - Shure Se215 Earphones (Clear)
