This guide will show you how to replace the headstrap on your HIFIMAN Sundara planar magnetic headphones.

In preparation for this guide, you will need the following tools:

  • Cutting pliers.

You will also need the following materials:

  • HIFIMAN Sundara
  • New HIFIMAN Sundara headstrap
  1. This step is necessarily destructive, and with careful application of the cutting pliers, no damage will be done to the headphones. Make sure to remove both fasteners.

    • The headstrap-headband interface is the piece of plastic which the headstrap itself adheres and whereby it attaches or interfaces with the headband. This part will be referred to as Interface for brevity from here on.

    DON'T CUT IT.
    from the inside of the headband, stick a flathead between the metal fastener and the plastic body, and pry downward carefully. the metal fastener should come free without breaking it.

  2. Remove the old  headstrap from the headband as shown by detaching the Interfaces from the headband.
    • Remove the old headstrap from the headband as shown by detaching the Interfaces from the headband.

    • A metal strip is present inside both of the Interfaces. Make sure to retrieve them and set them aside in a salient location.

    • Remove the drivers (speakers) as shown.

  3. Insert the new headstrap as shown into the headband by inserting the Interface into the headband, but do not yet press the Interface into the headband.
    • Insert the new headstrap as shown into the headband by inserting the Interface into the headband, but do not yet press the Interface into the headband.

    • Don't forget to re-insert the metal strips mentioned in Step 2 here as shown in the video.

    so how does this go back together? very little text and the important part of the video is covered by a hand

    morally dubious -

    If iFixit allowed for better guide production, I could probably have provided additional images, but for some reason, videos and images are incompatible (at least at the time of making this guide). Unfortunately, I can't elaborate until I get home, and I don't know when that will be. It could be a week, or it could be a few months, as that's where my (broken) Sundara's are that are in need of repair.

    iFixit is great, but someone needs to fix this awful guide interface.

  4. As the design of the headband is ambipolar, which side of it is designated as the left or right side does not matter.
    • As the design of the headband is ambipolar, which side of it is designated as the left or right side does not matter.

    • Before inserting the drivers back into the headband, make sure to slip on the metal fasteners, one for each driver, onto the extension adjustment.

    • Make sure the metal fasteners have the written polarity, either L or R, facing on the inside.

    • After ensuring the fasteners are facing the correct direction, slide the drivers back into the headband and firmly press closed the Interface as shown in the video.

  5. Firmly push the metal fastener upwards to permanently secure the Interface to the headstrap as shown. No adhesive is required.
    • Firmly push the metal fastener upwards to permanently secure the Interface to the headstrap as shown. No adhesive is required.

    • Make sure to apply equal amounts of force as you push the fastener onto the Interface.

Abschluss

Headstrap replacement is complete.

you absolutely do not need to cut the metal fastener in step 1. just pry it downward carefully with a flathead screwdriver and it comes free.

Thanks for this tip, had to deal with a loose headstrap and it is very easy to just pry it with a screwdriver. You don't even dent it at all if you're careful.
