HIFIMAN SUNDARA Over-ear Full-size Planar Magnetic Headphones (2nd Revision)

  • Utilizing a new, hi-tech diaphragm means that the diaphragm is 80% thinner than was on the HE400 series. This results in more detail, faster transients and an extended frequency response.
  • New headband design offering a separate head strap which allows for the headphone weight to be spread perfectly evenly over the wearers head. It delivers both a more comfortable fit but also a more eye pleasing look.
  • The all new Hybrid Headband gives a structure intended to be as practically street friendly, built to take the wear and tear of everyday life while looking great as it does it.
  • The Headphone cable attachment uses the standard 3.5mm socket which gives improved connectivity and is more physically robust connector too.


    • Frequency Response: 6Hz - 75kHz
    • Impedance: 37 ohms
    • Sensitivity: 94dB

    An All Rounder

    Brings The life out of guitar strings and instruments and equally shines in pop and electronic while providing pinpoint imaging for competitive gaming. Worth every penny.

    Definitely Best Planar in this range

    I have never used any planar, so cannot compare, but giving a great sound, need a loads of amping though.

    Very good

    needs an amp though and needs some bass (amp and good eq may fix it). but really good and really good imaging to work with dolby access for gaming.

    HIFIMAN SUNDARA first thoughts

    I just got my HIFIMAN SUNDARA from Gears for Ears. Buying experience was very good. Delivery was very fast.

    I can't do a detailed review for 2 reasons. First of all, I only just got it and secondly, this is my first headphone in this range.From a general user perspective, It feels solid, looks nice feels comfortable to use. The provided cable is a bit stiff, curly and short. But I had ordered replacement cables for them so that never bothered me. As for the sound, they started out sounding harsh but within an hour of listening the sound started getting warmer. It is not my ears getting used to the sound. In the beginning there was a lot of sibilance and very little bass presence but after an hour the sibilance was almost gone on the same song and some bass was there. So I expect the sound signature is going to change further as I burn it in. I have been listening to it on a iFi Zen DAC connected to an xDuoo TA-20 Tube Headphone Amp. Also on Ear Studio ES100 Bluetooth Receiver. It already sounds better than any headphone I tried before (which does not say much as I have not really tried any mid or high end headphones). My main reason for choosing these were however the comfort. I tried closed back headphones but never could use then as they got hot after a while. So far these don't seem to have that problem. I have a feeling I'll get to love them more as time goes by.
