FiR Audio M4 - Hybrid High-End IEM

M4

Musicality at the forefront.

The M4 values ​​responsive, musical tuning and combines 4 drivers with FiR's unique technologies to achieve the best possible reproduction of this tuning. A dynamic driver provides extended and structured bass, paired with three BA drivers that cover the midrange and high-frequency range, providing a smooth, expansive yet high-resolution sound signature.

The interior design is constructed with our proprietary tubeless design and 3rd generation atomic pressure release system, giving musical sound an even larger soundstage and a pneumatic, pressure-free listening experience that is best suited for singers, 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 customization at no extra charge.
