Features & Specs
4.4mm balanced in-line attenuator for sensitive IEMs and headphones
Designed for balanced 4.4mm setups, it sits between your source and earphones to better match sensitive loads and improve listening comfort.
High (-12dB) or Ultra (-24dB): Two sensitivity modes let you tailor attenuation to your earphones, reducing excessive loudness at low volume and helping fine-tune listening levels safely.
Two sensitivity modes let you tailor attenuation to your earphones, reducing excessive loudness at low volume and helping fine-tune listening levels safely.
Reduces hiss and improves perceived dynamic range and clarity
By lowering gain and noise floor, it helps reveal more detail—especially in quiet passages—while making vocals and instruments sound cleaner and more defined.
minZ™ helix cable minimizes capacitance/inductance with intrinsic shielding
The helix geometry is engineered to keep the transfer path clean and help block RFI/EMI interference for more stable, consistent playback.
Premium build: 6N silver/copper matrix wiring and aluminium-magnesium shell
High-purity conductors and a robust metal shell support long-term durability while maintaining audiophile-grade signal integrity.
Gold-plated connectors and gold-plated PCB with audiophile components
Gold-plated contact points and quality parts (including MELF resistors) are chosen to maintain reliable connectivity and transparent performance over time.

iFi iEMatch+ - 4.4mm Optimizer/Attenuator
The iFi iEMatch4.4 is a precision 4.4mm balanced in-line attenuator and impedance-matching adapter designed to tame hiss, unlock cleaner dynamics, and give ultra-sensitive IEMs and headphones a quieter, more controlled listening experience. By lowering output gain with selectable High (-12dB) or Ultra (-24dB) sensitivity settings, it helps restore usable volume range, improve perceived resolution, and reduce background noise when pairing sensitive earphones with powerful sources like DAPs, portable amps, and balanced outputs. Its custom minZ™ helix cable design is engineered to minimize capacitance and inductance while providing intrinsic shielding to help keep RFI/EMI interference out of your signal path. Finished with premium materials—including 6N silver/copper matrix wiring, a rugged FINAL6063-T5 aluminium-magnesium alloy shell, and gold-plated 4.4mm connectors—the iEMatch4.4 is built for audiophile-grade transparency without sacrificing portability.
What It's Good At:
Reducing audible hiss and noise floor with sensitive IEMs on balanced 4.4mm outputs
Restoring smoother volume control and safer listening levels by lowering gain (-12dB / -24dB)
Improving clarity and perceived dynamic range for more defined vocals and detail
Preserving tonal balance with 0% frequency loss design intent for transparent playback
Fighting interference with minZ™ helix geometry and intrinsic shielding against RFI/EMI
Delivering premium durability and signal integrity with gold-plated connectors and quality components
iFi iEMatch+ 4.4mm Full Specifications:
Product Name: iFi iEMatch4.4
Compatibility: Works with all 4.4mm balanced devices (4.4mm balanced male input to 4.4mm balanced female output)
It reduces output gain and helps match impedance so sensitive IEMs and headphones run quieter, with less hiss and better control on powerful balanced sources.
When should I use High (-12dB) vs Ultra (-24dB)?
Use High (-12dB) for most high-sensitivity headphones/IEMs, and switch to Ultra (-24dB) if your earphones are extremely sensitive or hiss is still noticeable.
Will it change the sound signature of my headphones or IEMs?
It’s designed to be transparent and improve listening conditions by lowering noise and restoring usable volume range, helping preserve clarity and dynamics without altering tonal balance.
Is the iEMatch4.4 compatible with any balanced device?
It’s made to work with 4.4mm balanced outputs and 4.4mm balanced headphone/IEM connections.
Does it help with volume being too loud at low settings?
Yes—by reducing gain, it makes volume adjustment smoother and gives you more usable range on the volume control.
Can it help with interference or noise from my source?
The minZ™ helix design provides intrinsic shielding and is engineered to help reduce RFI/EMI-related noise entering the signal path.
What materials are used in the iEMatch4.4?
It uses 6N silver/copper matrix wiring, a FINAL6063-T5 aluminium-magnesium alloy shell, and gold-plated connectors plus a gold-plated PCB with audiophile-grade components.
