Product Highlights

FATfreq x Effect Audio Quantum. Impedance: 38 ohms. This collaboration features a 14.2mm planar magnetic driver and FATfreq’s Bass Cannon technology. It incorporates the modular Noah tuning system, allowing for adjustable sound profiles like Super Stage or Power. Housed in a brushed metal shell with a premium Effect Audio Signature Series 2 cable, it produces a punchy U-shaped signature. This design yields deep sub-bass rumble alongside the speed of a planar driver, maintaining clarity in the mids and an energetic, controlled treble.

Cited as a 2025 benchmark, reviewers laud its blend of visceral bass and high-end technicality. The modular system provides versatility, offering a tailored listening experience that remains tight and detailed. Although it benefits from strong amplification, its engaging and refined sound profile makes it a standout for enthusiasts seeking elite performance. This IEM offers a sophisticated balance of power and precision.
