3D Printed HiFiMan HE400se Super Grills
These inserts replace the original grills for the HiFiMan HE400se to make them sound more open. This re-tunes them slightly to give more sub bass.
They require double sided tape to stick the driver wires to the black felt around the outside of the driver. This ensures that the wires do not get in the way when installed. They must not be on the magnets.
We also recommend removing the fabric from the back of the original grill and placing it on top of the magnets. This helps prevent hairs or other debris getting inside.

Firstly for the tl;dr crew out there: This is a simple to do but very effective mod. At the asking price it is a no brainer if you fancy some planar goodness.
I bought my HE400SE a couple of years ago and I was going to do the seXY mod to them. I soon realised that I was too clumsy, short on time and lazy for that kind of tomfoolery.
I was very excited to see the video announcing the idea of this mod and have been waiting since. £19.99 later and they arrived with me to try. I had not listened to the SE for a while so I did that first to remind myself of their flavour.
A couple of minutes fighting with double sided tape to get the wires out of the way, two simple click clicks and off I went.
I really like how the grills look and they have turned a pair of headphones that were sat gathering dust in to my listening while working daily driver. The boost in sub bass is excellent, they allow me to listen more quietly while still getting that slam, I am not getting any younger and so appreciate the ability to preserve my hearing while still having an enjoyable listening experience.
I still prefer listening to my old HD540 Reference when I have time to properly listen but the Super Grilled HE400SE punch way above their weight. I pair mine with a Topping L30II and I find that combination mind-blowing value at under £300 for the pairing.

Got the custom grills for the he400se. Love the sound improvement! It’s hard to improve without having a negative but these do it, the bass improvement is noticeable and totally worth it!
Price was great. I love that they don’t gouge you, totally worth the price.

Bought 3D design and print them by myself.
Unbelievable sound improvement. Used regular version of HE400SE, not “stealth” magnets. Many thanks

amazing mod, an improvement over a standard open 3d-printed grille. Improves the separation and details + better sub bass for sure
David Peachey –
These are great! IIt’s an improvement without ruining the original sound. Better detail and sub bass as others have said. Where I feel it’s improved the most though is the open feeling of the headphones. I found the HE400se to be oddly closed feeling but these open them right up. They are also less fatiguing to listen to for some reason.. I don’t know if that’ from being more open or if these also tame some high frequency that would hurt my ears a little over time.
The installation was a little tricky dealing with double sided tape. It doesn’t come with tape either so make sure you get some. I had some carpet tape laying around which worked ok. Also the right cup was super tight for some reason and one of the clips snapped off but once it was in it’s so tight that it’s not an issue.
Overall these are great, improving the sound with no negatives that I can hear.

Appreciate the sound quality improvement and of course the super, super fast shipping. Good stuff!
It’s great to see new and exciting ideas like this become real products.
The installation was relatively easy and straightforward as well.
One problem were the clips on the edges of the super grills however, of which at least 1 unfortunately snapped off on both of them.
There appeared to be a weakspot in the outer layers where the clips are connected to the rest of the 3D print – which is where these layers then disconnected from one another during installation, and the clips with them.
Not that much of a problem, but still unfortunate.
Perhaps adjusting a setting or two for the 3D print and / or trying out different kinds of printer filament could have a positive effect somehow.

After changing the cable of my HD400SE, I thought that was the end of the upgrade road. Then I came across the super grills. As noted by another reviewer, the price makes it a no-brainer. I’m still working out what has improved because there’s so much to take in. My first impression is everything is better!
I also snapped off clips. The grills still fit OK though. I eagerly await the next mod.

These grills does open up the sound. Deepens the bass and brings air, details and extension into the highs. Mids are still forward. Pure magic.
