The matte black Crossfade M-100 Headphones from V-MODA feature a design that was crowdsourced from multiple producers, DJs, and V-MODA. They have 50mm dual-diaphragm drivers that have been quality tested at six separate frequencies to assure consistency in performance. The M-100s have a steel frame and headband designed for durability. The memory-foam earpads provide a comfortable fit and help provide passive noise-isolation. You can mix two sources simultaneously to the M-100s by connecting individual sources to the inputs on both earcups.
