HIFIMAN is one of our favorite high-end headphone manufacturers and we have owned their products for many years. The Sundara open-back headphones have been one of their best models for many years and they were certainly due for a refresh. We’re just surprised by the nature of the new design. The new HiFiMAN Sundara closed-back planar magnetic headphones have been announced and we have a lot of questions.
Open-back vs Closed-back
While there are always variations between specific headphones, in general, an open-back headphone allows outside air to pass through the earcup, allowing for a more natural open sound, but doesn’t prevent some sound from escaping nor does it keep out exterior ambient noise. However, if you are listening in a quiet environment, open-back headphones may be a great choice as they may be more comfortable over long listening sessions and they offer a more spacious sound.
A closed-back headphone offers users a sealed earcup so that you get all the sound from the headphone drivers (including enhanced bass response) as well as limited exterior noise. However, depending on brand/model, they tend to be heavier and may not be as comfortable as open-back headphones over a long period of time.

Sundara Closed-back Headphones
The HIFIMAN Sundara closed-back headphone features stylish hand-assembled beechwood ear cups. The earcups isolate the listener from background noise and emphasize a more natural bass response typical of closed-back designs.
The Sundara features Stealth Magnet Technology which significantly reduces reflections and diffractions that distract from the sound quality.
Tip: HIFIMAN first introduced Stealth Magnet Technology in their Arya Headphones.
Like the open-back version, the closed-back Sundara features HIFIMAN’s ultra-thin Super Nano Diaphragm which is up to 80% thinner than diaphragms in many other headphones.
The Super Nano Diaphram also supports an ultra-wide frequency response of 6Hz-50kHz, which allows the fine details present in well-recorded music to be easily revealed.
- Impedance: 20 ohms
- Sensitivity: 97dB
- Weight: 1 pound
According to Dr. Fang Bian, Founder, and CEO of HIFIMAN: “Sundara is a Sanskrit term meaning ‘beautiful’ and ‘noble,’ both of which are accurate descriptions of the new headphone design, inside and out. Music lovers will enjoy the new Sundara Closed-Back as much if not more than the original open-back model.”
Availability & Pricing
The Sundara closed-back over-the-ear planar headphone is expected to ship sometime in August 2022 for $399.
Tip: Both versions of the Sundara are wired headphones with a 3.5mm connector and cable provided.
