Hifiman HE400SE

Hifiman HE400SE planar magnetic headphone, over ear, open back. HE400se uses technology trickled down from higher end models, with new Stealth magnet design that helps open up the soundstage and provide improved clarity.

HE400se provide excellent clarity, natural, balanced tuning and a more open sound than most other headphones in their price range. Comfort is very good, with a deeply padded headband, large earcups and little pressure, you can wear the HE400se for hours at a time. The 1.5m cable is detachable, with dual 3.5mm connectors on the headphone, a 3.5mm plug and 6.5mm adaptor.

The impedance is low but the sensitivity is also lower than many headphones, so you will get better results with a dac/amp that can provide more power than a computer or phone.
