Connect the iEMatch2.5 between them and your DAP for reduced background noise and hiss.
Some headphones are more sensitive than others so the iEMatch2.5 has both High and Ultra sensitivity settings to boost your sound. Choose which best suits your headphone.
It also provides a more open and transparent dynamic range and increases the usable volume range. This means you can increase the digital volume and get back the resolution you lose by listening at less than full volume. Rediscover the lost high-pitched note of the E-string or the low rumble of the bass drum.
Take the iEMatch2.5 with you. Pop the iEMatch2.5 into its handy velvet pouch with the included memory foam earplugs and aeroplane adapter and take it with you, wherever you go. The perfect travelling companion.
To hear everything from the high-pitched jingle of a tambourine to the deepest rumble of a kettledrum, you need a wide dynamic range. With great DACs, DAPs and headphones, the sound of EVERYTHING will be boosted, including the self-noise of the source AND the sound level. Plus some higher-end headphones and IEMs add to this by being sensitive themselves.
To build a system around an expensive high-resolution headphone amplifier and then use it at a comfortable (not to mention safe) listening level means you have to turn the volume down to about 60% of its capacity. This will decrease both its dynamic range and audio quality. It’s like watching HD TV with some of the pixels from the screen missing. You lose around 2 Bits of resolution.
