Balanced, warm, and soft – this is the best way to describe the sound profile of the MACH 40, perfect for those seeking a particularly well-balanced listening experience. The MACH 40 in-ear headphones feature a proprietary four-driver system with two woofers, one midrange, and one tweeter, along with a passive 3-way crossover. The ergonomic and extremely lightweight design allows for all-day use of the headphones without causing fatigue. The included T2 SuperBaX cable from Linum is a true premium high-end reference cable designed for audiophile standards. With a low resistance of 0.75 ohms, the SuperBaX cable supports particularly pure neutral sound reproduction. The cable is exceptionally durable and does not tangle. To ensure safe storage and transport of the headphones, a shatterproof waterproof hard case is included. Additionally, you will receive five pairs of foam ear tips and five pairs of silicone ear tips in various sizes, allowing for comfortable placement of the headphones with a perfect seal in the ear canal. The MACH series from Westone Audio combines over 35 years of technical experience in the development of in-ear headphones. Every aspect of the MACH series has been designed for musicians on stage or audiophiles in their daily lives. With the MACH series headphones, you will hear music exactly as it was meant to be heard.
