Hiss-Busting Headphone Accessory
Do your headphones suffer from hiss and pops or an irritating loud blast? If they do, you need Ear Buddy, the hiss busting headphone sidekick from iFi Audio. The Ear Buddy fits between your headphones and your smartphone, digital audio player, computer, or other gear. Just plug in Ear Buddy and enjoy listening like never before. The Ear Buddy gets rid of annoying hisses and buzzes and allows you to turn up your digital volume to a higher level to improve resolution and quality.
Crank Up the Volume (Safely)
Normally you probably listen to music through your headphones with the digital volume control set at 60% at most. This means you have lost 2-Bits of resolution. Basically, it’s like watching HD TV with some of the pixels from the screen missing. It’s okay, but you are not getting what you paid for.
You can turn up your phone or music player to full volume, but your ears (or the people around you) would not thank you for it. Adding the Ear Buddy ‘attenuates’ or adjusts the volume and safely allows you to crank up the digital volume on your smartphone or DAP without painful consequences. This equals more music information being conveyed and gives you back those 2-Bits and the full hi-res music experience.
Please note that ear safety is of critical importance, so always check to make sure that you are listening at a healthy level, no matter what gear what you're using.
The Big 2-Bit Difference
How does iFi Audio figure you gain a 2-Bit difference with Ear Buddy? All smart devices use a digital volume control. The very nature of digital volume controls means that at normal 50% listening levels, the actual resolution is 14-Bits instead of 16-Bits.
If a source has (say) 114dB dynamic range and the headphone is 30dB too loud, once the volume has been turned down 30dB, the dynamic range is reduced to 84dB, or to below CD quality.
Hiss is very annoying when listening with headphones. It's caused by the mismatch between too much power from the smartphone or other audio source when used with headphones which have high sensitivity. The solution by iFi is to ‘attenuate’ or adjust the signal in order to cut out the hiss and put the enjoyment back into listening.

Ear Buddy Tech Facts
Ear Buddy provides a high-gain (-15dB) sensitivity adjustment and uses a gold-plated printed circuit board with audiophile components (e.g., MELF resistors), 6N (99.9999% pure) high-purity copper matrix wiring, and gold-plated 3.5mm male and female connectors. The input impedance is >16 Ohm and out output impedance is <1.5 Ohms. Compatible headphone impedance is 16 Ohm to 600 Ohm rated impedance and 12.5 Ohm minimum impedance.
