HE-4
Lightweight Planar Magnetic Headphone for the Critical Listener.
HE-4

HE-4 is the single end version of HE-5LE: very similar sound signature. Because HE-4 only have 50% magnet in HE-5LE, it is much lighter (350g).

HE-4 requires a powerful headphone amplifier to drive it. Our EF5 headphone amplifier can serve 2 watt per channel.
