FIR Audio M4 - 4 Driver Hybrid (1DD+3BA) IEM Earphone Universal / Custom IEM with Tubeless Technology
Musicality at the four-front.
Placing a priority on an engaging, musical tuning, the M4 pairs 4 drivers with FiR’s unique technologies to achieve the best rendition of this tuning possible. Utilising a dynamic driver for well-extended and highly textured lows, this is paired with 3 balanced armatures covering the midrange and high frequencies, tuned for a smooth, vast and yet highly resolved sound signature. The internal design is constructed with our proprietary tubeless design and the 3rd generation atom pressure release system, lending the musical sound an even larger soundstage presentation and a pneumatic pressure-free listening experience best suited for vocalists, keyboardists, guitarists and audiophiles.
Like all our other models, the M4 comes with our unbeatable 3 year warranty with the super-reliable RCX connection standard, and unlimited design customisation at no extra charge.
Range: 10hz - 20Khz
