Designed for the serious audiophile, the Westone W30 uses separate bass, mid-range and high frequency balanced armature drivers in conjunction with an advanced 3-way crossover for a truly awesome listening experience. Westone's 50+ years of experience with in-ear applications has yielded a low-profile, lightweight, universal earpiece which delivers maximum comfort and in-ear coupling for dynamic transfer of sound. A replaceable cable connection includes the braided EPIC cable and round MFi cable with 3-button Apple Control System and mic function, including volume +/- , tracking +/- , phone answer, and Siri activation. Westone's balanced armature drivers are significantly more compact and efficient than traditional dynamic drivers. By combining multiple balanced armature drivers with sophisticated crossover networks, Westone monitors provide enhanced sonic detail and a frequency range that extends well beyond typical in-ear solutions. Exchangeable black, blue and red color faceplates are included with secure attachment. Each set of W30 in-ear headphones comes with an EPIC replaceable cable and MFi G2 cable, premium comfort tips, mini-monitor vault, cleaning tool, and 2-year warranty. The Mini Monitor Vault is constructed of a high-impact polymer and is the perfect size for travel and storage. The Westone W30s are ideal for listening to hard rock, alternative, electronica, R&B, funk, country, ska, and punk, delivering amazing reproduction of recorded/mastered music in a universal-fit earphone for the serious audiophile.
