HiFiMan HE400i Full-size Planar Magnetic Headphones and EF2C Amplifier Combo

The new HiFiMan EF100 amplifier is a great complement to the HiFiMan HE560. They have packaged them as compelling combos to deliver outstanding performance and exceptional value.

HE400i
A Full-size Planar Magnetic Headphone Intended for High Performance Listening in the Home or Studio You spoke and HiFiMan listened. The popular HE400i is now being shipped with 2.5mm plug-in connectors rather than the traditional "Screw on" type that HiFiMan has used for years. Performance -s identical and there is no change in price. Increased efficiency of 93dB allows it to b driven with a modest size amplifier or can even be used with a portable audio player or smartphone.

Planar Magnet Headphone
Created by the innovator of the planar magnetic technology, the HiFiMan HE400i is a high quality, full-size planar magnetic head phone created for critical listening at home or in studio. The new generation headphone becomes more lightweight with largely improved sensitivity.

Planar vs. Electrostatic Planar magnetic and electrostatic drivers are similar in regards to low distortion and high signal input. Compared to the electrostatic driver, the planar magnetic technology uses a more massive diaphragm that is able to move very quickly in a coherent and uniform way. The planar magnetic head phone gives excellent transient response and a sound quality almost equal to that of an electrostatic product.

Breakthrough Innovation
Single-ended planar magnetic drivers provides superior soundstage and spatial imaging.

Lightweight Comfortable
The HE400i is 30% lighter than other full size planar magnetic designs for increased comfort.

Lively Agile
Using single ended drivers, HE400i delivers a lively soundstage and spatial imaging.

The Look
• ABS polymer ear cups in a gloss charcoal finish give the HE400i a striking contemporary look
• Improved pressure pattern is designed to provide best-in-class comfort
• Specially designed beveled ear pads are made of pleather and velour, which provide both increased comfort and improved sound quality

EF2C

Sublime and Organic Tone from the Vacuum Tube
Combines the beautiful, warm sound signature of vacuum tubes with the advantages of low distortion and high S/N rate from the solid-state amplifier.

Hybrid Design: Vacuum Tube + Solid State Performance
The hybrid design employs two 6J1 tubes for its input stage and incorporates the 0PA2604 along with discrete components tor its output.

Step Potentiometer for Improved Volume Attenuation
The Step Potentiometer is designed for precise control and accurate channel balance (with less than 0.0001 in errors). This results in excellent channel balance and soundstage.

Hi-Fi Sound Quality
The EF2C is meticulously designed for the most discriminating music listeners who demand the best performance and value.

Style and Power
A compact desktop design with an integrated USB-DAC inherits the power and performance from the EF2A. The EF2C is the perfect match for most PC-driven audiophile head phones.
