Hifiman Sundara is a full size, open back planar magnetic headphone. An upgrade from the HE400-series models, the driver is 80% lighter weight and it really shows in the sound - Sundara has excellent detail and clarity. Separation of sounds is well handled, midrange is very clean and treble extension is very impressive and much improved.
Sundara shows improved build quality, with metal arms and headband, improved ear pad quality and sleek metal ear cups. Sundara has a clearly tight build quality and more mature, richer looking design. Comfort has improved as well, Sundara is now one of the more comfortable planar headphones with its suspended headband.
94dB sensitivity means these need more than a phone or computer to sound their best. Match with a dac or headphone amp for impressive performance. iFi's new ZEN dac or CAN amp make a great match, as does the TR-Amp or Fiio K5pro. If you like a fuller, fatter sub bass, the TrueBass feature on the ZEN dac does a great job.
