Hifiman Sundara is a full size, open back planar magnetic headphone. Replacing the HE400-series models, the Sundara shows improved build quality, with metal arms and headband, larger 3.5mm connectors, a thicker but still pliable black cable with heavy duty 3.5mm plug, 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 most comfortable planar headphones yet.
Hifiman says the new driver is 80% lighter weight than the HE400 series drivers and it really shows in the sound - Sundara is a solid upgrade from the HE400 series, with excellent detail and clarity. Separation of sounds is well handled, midrange is very clean and treble extension is very impressive and much improved.
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 dacs are good suggestion and we're getting great sound quality with them in store.
