iFi Audio Match Yonten Balanced Terminal Compatible Attenuator Hiss Noise Reduction Silver iEMatch4.4 (IE Yong) 4.4mm []

【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.

[About clocks that synchronize time via radio waves] The function of clocks that synchronize time via radio waves only works in the Japanese area. Please be careful. Making any earphones/headphones sound perfect is an extremely difficult task for a headphone amplifier. iFi has approached this challenge in two main ways. The iEMatch feature provides gain switching and appropriate attenuation for sensitive earphones. These two functions were first included in the micro iDSD and are widely used in iFi's head-fi (headphones and hi-fi) products. Additionally, the iEMatch function was later made into a standalone product. The latest product in the iEMatch series is iEMatch4.4. It maintains the features of the already released and current product iEMatch+, but now supports the currently mainstream 4.4mm balance standard. The main features are as follows. ・2 types of gain sensitivity adjustment: Ultra (-24dB) and High (-12dB) ・Gold-plated 4.4mm plug/jack ・The shell of the plug/jack part uses iFi FINAL aluminum-magnesium alloy (A6063) ・Cable conductor is silver-plated 6N copper wire, and the structure has iFi's unique shielding effect. Double-helix construction design minimizes impedance in the transmission path Internal attenuator circuitry is constructed from a gold-plated PCB using audiophile-grade components (e.g. MELF resistors) Works with iEMatch4.4 with any headphone amplifier For example, it can improve volume adjustment problems that occur with high-sensitivity IEMs. Equipped with a 2-stage gain (-12dB/-24dB) switch, you can select the optimal setting according to the amplifier's output level and earphone sensitivity. In addition, since it is not a digital calculation, there is no deterioration in sound quality such as bit loss, and it can also be expected to reduce residual noise. iEMatch4.4 has taken measures in every part to eliminate the effects of inclusions called attenuators. The 4.4mm plug/jack contacts are gold-plated, and the attenuator circuit is constructed using audiophile-grade parts on a gold-plated PCB. The cable is connected to the transmission path by iFi's unique helix structure design. It has a shielding effect while minimizing the impedance at the terminal. Using iEMatch4.4 results in increased dynamic range, reduced background hiss, and clearer vocals. iEMatch4.4 is a top-of-the-line attenuator that can bring out the sound quality of a headphone amplifier while minimizing the effects on sound quality.
