Hifiman HE400SE mods

Does anyone in here have mods that they have done to their HE400SE that improve the look or quality of sound? If so, please share in this thread. I am looking to make some mods and my cousin has a CNC router and was thinking of getting a second set of HE400SE’s to play with. Maybe design some solid wood cups or something. Any idea is welcome and greatly appreciated.

The main, popular, and easiest mods are grill, ear pads, and headband (if you find the stock ones uncomfortable or prefer the look of something else).

Yeah, I was looking at doing the DIY grill thing. I love that look and I’m sure it would have a more open soundstage and better air. I honestly don’t mind the headband myself, but if they had a headband similar to the susvara I would be down for buying it.

I did grill mod, leather strap, and silver cable.

I love it, I ordered a 4.4mm cable upgrade. How did you do the leather strap and grill?

I’m sure the Susvara or HEK headbands would work too. There was a user who had the HEK on an Audeze LCD-3 (pre-production) and we’ve seen HE6’s with Audeze headbands.

The grill is on ebay. just search for hifiman grills

The leather strap I made. I just bought leather material from any arts & crafts store (i bought mine at Michaels, or Hobby Lobby). I then cut it to the shape I wanted, punch two holes on either end, and used black twist ties to hold it to the headband as shown in the pic. Total cost is under $10.

Thank you, the grill will be here Monday and I am heading to Michaels soon.

Nice!

For reference, I make my strap roughly 10 inches long, and 2.5 inches wide, with it necking down a little bit near the ends, but that’s not probably necessary.

Oh I bought a leather puncher at the store too, just to make it easier, but you can probably use something else if you dont want the spend money on that.

@antdroid One more question, how did you get that sheet to stay in place when you put the new grills on?

Some craft glue on the grills, then put the sheet/mesh cloth over.

Yep, I used spray-on adhesive. I believe it was just elmer’s brand.

That is genius, I don’t know why I didn’t think of that. Thank you so much!!! I listened to them with no filter and they sound incredible. I turned my EQ off cause they didn’t need it anymore, it’s like it fixed that 2k dip.
