iFi iEMatch+ 3.5mm Male to Female Headphone Jack In-Ear-Monitor Audio/Optimizer/Attenuator

AUDIO ATTENUATOR- iEMatch reduces the hiss, pops, and background noise that distracts from your music (nearly zero output impedance).The attenuator removes extra sounds and restores the bits of resolution that are lost at regular/low digital volume. SAVE YOUR EARS - Instead of blasting music to hear a little more sound, this device expands the volume range where you can hear clear audio on lower volumes (boosts dynamic range). The iEMatch is ideal for in-ear-monitors (IEMs), custom earbuds, or in-ear headphones. BALANCED SOUND -The iEMatch can be switched between single-ended or balanced 3.5 outputs with the TRRS jack on both ends. Switch between High or Ultra Sensitivity to match your headphones. Works great as an analog sound adapter for a smartphone, digital audio player and other music sources. HEAR MORE MUSIC - The gold-plated 3.5mm balanced connector and 6N silver/copper matrix allow for better signal transfer. Hear all of your music, from the highest soprano to the lowest bass. TRAVEL COMFORTABLY - Adapt sound from airplane in-flight systems, Digital Audio Players (DAP), smartphones, portable players, tablets, computers, and more. Includes a velvet pouch, gold-plated airplane adapter, and memory foam contoured earplugs.
