Do you want to optimize your listening experience with a balanced headphone? The iEMatch4.4 effortlessly reduces background noise, clarifies voices, increases dynamic range, and generally improves sound quality by adjusting the output level of your device. The iEMatch4.4 works with all devices that have a balanced 4.4 mm headphone jack. The short iEMatch4.4 cable features a switch to optimally set the gain in two stages for your in-ear monitors or headphones. With the Ultra-Sensitivity setting, the gain is reduced by 24 dB, and with the High-Sensitivity setting, it is reduced by 12 dB. By attenuating the output level, you can raise the volume of the music source and listen to your music in the optimal adjustment range. The iEMatch4.4 thus restores lost dynamics, reduces annoying background noise, and improves overall sound quality. This way, you can get the best out of your most sensitive earphones and headphones. The iEMatch4.4 is simply connected between the music source and the earphones/headphones. The cable is very compact and lightweight, extending the headphone cable by just a few centimeters.
