This B&H Kit includes clear Shure SE425 Sound-Isolating In-Ear Stereo Headphones and a CBL-M+-K-EFS In-Ear Headphone Accessory Cable with Mic and Remote. The SE425 headphones use dual high-definition MicroDrivers, which means there is a separate woofer and tweeter in each earphone for rich, detailed audio across the full frequency spectrum. They also 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 CBL-M+-K-EFS In-Ear Headphone Accessory Cable with Mic and Remote transforms your SE425 detachable earphones 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.
