The HIFIMAN Sundara is an open back planar magnetic headphone. Derived from the Sanskrit word for “beautiful,” the Sundara is a fast, detail-rich headphone that lives up to its name. Joshua Valour reviewed it as “one of the fastest headphones [he’d] ever heard” with “phenomenal” imaging and a “very comfortable” fit.

Supernano diaphragm

When it comes to detail retrieval, no factor is more important than the diaphragm. Required to oscillate up to 20,000 times a second, most diaphragms, which are made of plastic or cardboard, can’t overcome the hurdle of their own inertia to reproduce lifelike detail. The Sundara, on the other hand, features a diaphragm that’s less than a micrometer thick. This exceptional thinness allows it to reproduce unparalleled details and lifelike imaging that you won’t find on other headphones. 

Durability meets comfort

The Sundara is built of lightweight aluminum for longevity and durability. And at only 13.1oz, it’s a pair that you can wear for marathon sessions. 

Hybrid headband design

As if 13.1oz wasn’t light enough, HIFIMAN equipped the Sundara with a weight-dispersing strap as a safeguard against hotspots and headaches.
