The SE425 in-ear headphones from Shure provide top-quality audio in a sleek, compact, noise-isolating design that's ideal for use at home or on-the-road. Based on Shure's experience with professional in-ear monitors, each of the earpieces has dual high-definition MicroDrivers, in essence putting a separate woofer and tweeter into each ear for rich, detailed audio across the full frequency spectrum. The ergonomic, professional design has a low-profile shape with an optimized nozzle angle for exceptional comfort.
