iFi Audio 0306049 iEMatch4.4 Headphone Volume Control Adapter (0306049)

iFi Audio 0306049 iEMatch4.4 optimizes balanced listening with better sound, increased dynamic range, reduced background hiss, and clearer vocals. It works with all 4.4mm balanced devices to help sensitive headphones and IEMs perform as intended.

Optimized balanced listening

Designed for 4.4mm balanced setups, iEMatch4.4 reduces background hiss and clarifies vocals while preserving dynamics for a cleaner, more controlled listening experience.

Tailor sensitivity to your headphones and IEMs

Choose the gain setting that suits your gear and preferences to get the most from even ultra‑sensitive headphones and IEMs.

• High: reduces gain by 12dB for high‑sensitivity headphones
• Ultra: reduces gain by 24dB for ultra‑sensitivity headphones

Trying both settings is recommended to find the preferred listening level.

Clean, shielded signal with minZ cable

The minZ cable uses a custom helix design that is minimized in capacitance and inductance. This construction provides intrinsic shielding to protect against RFI and EMI for the cleanest possible transfer medium.

• Custom minZ helix construction with intrinsic shielding
• 6N silver/copper matrix wiring with FINAL6063‑T5 aluminium‑magnesium alloy shell
• Gold‑plated printed circuit board with audiophile components (e.g., MELF resistors)
• Gold‑plated 4.4mm male/female connectors

Simple, instant improvement

Just insert iEMatch4.4 between your headphones/IEMs and the output of your smartphone, DAP (digital audio player), or music source to instantly improve playback and adjust volume on the go with lower background noise and maximum dynamics.
