Balanced, warm and smooth - that's the best way to describe the sound of the MACH 40 - perfect for those who want a particularly well-balanced listening experience. The MACH 40 in-ear earphones feature a proprietary four-driver system with two woofers, a midrange and a tweeter, as well as a passive 3-way crossover. The ergonomic and extremely lightweight design allows for all-day use of the earphones without causing fatigue. The included Linum brand T2 SuperBaX cable is a true premium high-end reference cable designed for audiophile demands. With a low resistance of 0.75 Ohm, the SuperBaX cable supports a particularly pure neutral sound reproduction. The cable is extremely robust and does not tangle. To ensure that the earphones can be stored and transported safely, a shatterproof waterproof hard case is included in the delivery. You also get five pairs of foam earplugs and five pairs of silicone earplugs in different sizes, so that the earphones can be placed comfortably in the ear canal with a perfect seal. The MACH Series from Westone Audio combines more than 35 years of technical experience in the development of in-ear earphones. Every aspect of the MACH Series has been designed for musicians on stage or audiophiles in their daily lives. With MACH Series earphones, you hear music the way it was meant to be heard.
