Look & Feel

For some reason, HiFiMAN’s closed-back headphones need to have this awkward bulge on their earcups. While this is probably the best implementation of this design, it’s still not very appealing to me, at least in terms of appearance. The construction seems better than past closed-back efforts from HiFiMAN though, with its flexible frame. HiFiMAN’s classic suspension headband is always a highlight, and it provides great comfort without any added pressure on your head. The fit doesn’t get very tight, but the cups are secure enough that you don’t need to keep adjusting them.

Design

The Isvarna uses a hybrid driver configuration that combines both planar and dynamic units. Both drivers contain an ultra-thin diaphragm that aims to reproduce a signal with ultra-low noise and a rapid transient response.

Soundstage

Sometimes with closed-back soundstages the barrier between closed and open is not as easy to define. This especially goes for high-end planar headphones, which seem to share more common qualities than in any other price range. The Isvarna’s soundstage easily passes for a great open-back soundstage in any price range. Its headspace might not share that HiFiMAN airiness, but this could work to its benefit, limiting it to make the sound elements more stationary in the mix. This way, the Isvarna retains its holographic dimension while featuring more exact imaging. It gives the Isvarna a closer studio feel without feeling too concentrated. Everything still spans very wide with excellent channel and sound separation that brings out each element individually. Vocals have great height, and stand out above the instrumentals allowing for the imaging to breathe naturally.

Low End

You might be expecting more from a closed-back bass response, but the Isvarna is relatively reserved. That’s not to say the bass content is lacking in any way though, as the Isvarna gives a lot of weight to its low frequencies. There’s a significant body to them, but the presentation of them is very well stacked. It allows for a more dynamic response that isn’t dominated by resonance, but one that gives the tone a clear shape in the sound signature. You can feel its mid-bass detail give off a definitive bloom, which gives the bass a nice scale and a smooth timbre.

Mids

More gain is given to the low-mids than other areas of the middle-frequency spectrum, but the Isvarna still has great clarity throughout. The Isvarna dedicates plenty of room for the midrange to exhibit fine detail and fullness. You can feel the weight of instruments come alive from their foundation and lose a bit of drive, but it never ceases to lack presence. It’s not an artifacts-driven midrange, but its smoothness articulates an intimate feel that compliments its closed-back sound. Vocals appear with a small veil, but it rarely distracts from their forward presentation.

Highs

The Isvarna brings some heat to its treble but it’s still tuned with control. You can sometimes hear some piercing details, but they rarely break through into an intense harshness. I like its presence though, as it comes across as lush and glistening. It shows a height and click that portrays instruments with a definitive tail and sparkle that I don’t feel is hard to digest.

Summary

The HiFiMAN Isvarna delivers a sophisticated listening experience, offering a unique mix of spacious soundstaging, controlled treble, and smooth mids—all wrapped in a robust yet comfortable design. Its dynamic balance and exceptional imaging make it a standout in the closed-back category. For audiophiles and professionals alike, the Isvarna proves to be a versatile and reliable choice that brings a touch of open-back magic to a closed-back format. My biggest concern with the Isvarna though is its price, which seems inflated to me. I enjoy the sound quite a bit, but comparing it to other closed-backs in the high-end, the Isvarna certainly seems the hardest to recommend.
