This adapter for the HE series with a balanced cable allows you to use your headphones directly out of your living room amplifier.This allows you to dispense with a dedicated amplifier for the brand's premium headphones. The efficiency of these great-sounding headphones is so low, that most headphone amps can't power them, so audiophiles would like to use them with their 'big' amplifiers. HiFiMan's HE-Adapter box connects directly to your integrated amp, power amp, or receiver using speaker cables. It's small, inexpensive, and lets you enjoy your HE headphones with a wide range of components.
