Westone Audio MACH 40 Wired Universal IEM

The smaller the IEM, the smaller the sound. It’s a common trade-off, but it’s not a foregone conclusion. Take Westone Audio MACH 40: an ultra-compact IEM packed with four balanced armatures to precisely articulately all areas of the audio spectrum. Westone has assigned two drivers to the bass side of the spectrum to provide a ton of oomph on the low end, while allocating one driver to each the highs and the mids. They’ve tuned this array to deliver a pleasing V-shaped spectrum that’s ideal for vocals and instruments—making the MACH 40  a well-rounded IEM perfect for reference, mixing, or even general listening. Each pair comes in Westone’s classic industrial-style enclosure design and ships with a detachable SUPERBaX cable that features high-quality T2 connectors.
