Singers, musicians, and music lovers will love the Westone MACH 50, a pair of 5-driver universal-fit in-ear monitors that feature warm balanced lows, mids, and highs with a 3-way passive crossover that provides clarity and responsiveness for any kind of music. The monitors are well suited for onstage monitoring, vocalists, guitar players, keyboard players, drummers, and sound engineers, as well as critical listening and general enjoyment. The earphones employ Westone's proprietary 5-driver system, utilizing a single low-frequency driver, two mid drivers, and two high-frequency drivers, which combine to deliver a frequency response of 8 Hz to 20 kHz at a sensitivity of 110 dB SPL. The MACH 50 features a Linum Estron SuperBaX cable with a low 0.75 ohm of resistance, to meet the needs of audiophiles in the constant pursuit of the perfect audio setup. The SuperBaX conveys music with precision and grace, while the lightweight cable disappears on your ear, allowing you to focus on what matters most. Included with these earphones are five pairs of silicone eartips of various sizes, five pairs of foam eartips (also in various sizes), an audio cloth bag, and an impact-resistant Pelican Case.
