Seeking an Easy-to-Drive Pair of High-End Headphones Distinguished by Lush, Vivid, and Responsive Sound? Comfortable and Lightweight HiFiMAN Sundara Even Pairs Well with Smartphones

Tonally lush, vividly dynamic, easy to drive, and a pleasure to wear: HiFiMAN Sundara planar-magnetic headphones arrive ready to play with an all-new diaphragm that is a whopping 80 percent thinner than those used in the company's HE400 Series models. The upshot is extra-wide frequency responsiveness, quick speed, and generous inner detail. And while Sundara spoils you with rich, mesmerizing sound, it will also gives your cranium a rest by way of an innovative weight-dispersing headband that results in accurate fit and addictive comfort. Weighing just 13.1 ounces, Sundara uses all-aluminum ear enclosures and touts a welcoming 94dB sensitivity that makes them a great match with smartphones. A sleek matte-black finish, fashion-forward looks, and a durable 3.5mm connector complete ‘phones sonically and aesthetically true to the meaning of their Sanskrit name: beautiful. 

  • All new floating headband design for extended comfort and accurate fit.
  • All aluminum ear enclosure ear pads
  • A newly developed diaphragm resulting in a wider frequency response

Great cans

First planar headphone and they sound amazing coming from only listening to dynamic drivers.

Unbelievably good

At this price range these are incredible. I just hope they hold up considering Hifiman's reputation for quality control

The best headphones I’ve ever used

Fantastic. I only used wireless headphones, which didn’t really have great sound qualities. With Sundara, I could know how well instruments could be separated.

Well these are glorious

This review is based on the original single-ended cable that comes with the headphones out of a BTR5 amp while I wait for the balanced cable to arrive. In short, they're awesome. I'm a bassist and I listen out for bass guitar and the Sundara's deliver those notes so well. They also reveal some interesting things I'd never noticed before like the fret buzz in Little Black Submarines (which became quite distracting the more I heard it. Seriously Black Keys, do better!) I tried them out using the little dongle Apple supplied. Don't bother with that, even my BTR5 at max volume just about pushes them satisfactorily. I need my balanced cable, now!

Disappointing Quality Control

There are a few chippings on the plating and right ear cup has considerably more swivel friction. Kind of frustrating but not a big deal.
