Engaging and musical tuning, the FiR Audio M4 Universal pairs 4 drivers with FiR’s unique technologies to this end. Using a dynamic driver for well-extended, highly textured lows, with 3 balanced armatures covering the mid-range and high frequencies, tuned for a smooth, vast, and yet highly resolved sound signature. Combining FiR’s Direct Aperture design and the 3rd generation Atom pressure release system. The M4 gives the listener musical sound with an even larger sound stage and a pneumatic pressure-free listening experience suited for vocalists, keyboardists, guitarists, and audiophiles.
