HiFiMAN HE-6 headphone

HE-6 - 50Ohm, 8 - 65 KHz Considered by many to be the world's finest headphone, without regard to price, the HiFiMAN HE-6 features the company's proprietary planar magnetic technology in a no-compromise design. With sensitivity of 83.5dB, the HE-6 must be paired with a headphone amplifier of comparable quality such as the HiFiMAN EF5 which delivers 2 watts per channel. The HE-6 is the reference choice of critical listeners around the world.
HE-6 requires a powerful headphone amplifier to drive it. Our EF6 headphone amplifier can serve 5 watt per channel at 50 Ohm.
