Protection for Your Amplifier and Low-Efficiency Headphones
The efficiency of HiFiMan's incredible HE-6
is so low, it requires more power than most headphone amps provide. The solution: HiFiMan designed the
small HE-Adapter box that connects the headphones via speaker cables to an integrated or power amplifier via the speaker outputs.
HE-Adapter is not for any high or average efficiency headphones, such as HE-300 and HE-500.
