The special-edition red Shure SE535 in-ear headphones 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 triple high-definition MicroDrivers, in essence putting a separate tweeter and dual woofers into each ear for rich, detailed audio across the full frequency spectrum with a deep bass response. The ergonomic, professional design has a low-profile shape with an optimized nozzle angle for exceptional comfort. The included fit kit contains multiple sizes of ear sleeves, allowing you to find the perfect size for your ear and effectively reduce ambient noise by as much as 37 dB so you can focus on your music. The detachable Kevlar-reinforced cable connects to the earpieces using gold-plated MMCX connectors to lock in place but also provide a 360° rotation. This rotation, along with the formable wire, allows you to direct the cable over and behind the ears to minimize snags and tangles. Bluetooth and 3.5mm cables—each with an in-line remote and microphone—are included, as well as 1/4" and airplane adapters for wide compatibility with consumer and professional audio devices, and in-flight entertainment systems. A compact and durable case is included for storage and transportation.
