If you’ve spent more than five minutes in the anime community, you’ve seen them. Those red, triangular, vaguely futuristic-looking pieces of plastic clipped into the hair of a girl with a fiery attitude and a giant robot. Honestly, Neon Genesis Evangelion hair clips—or interface headsets, if we're being nerds about it—are probably the most successful piece of character design branding in the history of the medium. They aren't just clips. They’re a statement.
I was at a convention last year and I counted at least forty pairs of these things before lunch. It’s wild because Neon Genesis Evangelion (NVA) first aired in the mid-90s, yet these specific accessories haven't aged a day. You see them on Asuka Langley Soryu, of course. She wears them constantly. Even in the shower. Even when she’s sleeping. It’s basically part of her skull at this point. But why are we still buying them in 2026?
What These Clips Actually Do in the Show
Most people buy Neon Genesis Evangelion hair clips because they look cool with a casual outfit or a full cosplay, but in the actual lore of Hideaki Anno’s masterpiece, they serve a pretty grim purpose. They are A10 nerve clips. In the world of NERV, pilots need to synchronize their thoughts with the Evangelion units. These clips facilitate that connection.
They aren't just "hair accessories." They are literal hardware.
Think about that for a second. Asuka wears her interface headsets in public because she defines her entire existence by her status as a pilot. She’s the "Second Child." Without the EVA, who is she? The clips are a constant, prickly reminder of her talent and her trauma. When you wear a pair of these, you’re not just wearing a cute red triangle; you’re wearing a symbol of one of the most complex psychological profiles in fiction.
The design is brilliant in its simplicity. It’s an isosceles triangle with a slightly recessed center and a metallic-looking "vent" or "sensor" area. Usually, they come in red to match Asuka’s Unit-02, but you’ll also find them in white (Rei Ayanami style) or even purple and green for the Unit-01 fans.

The Evolution of the Merch
Early versions of these clips were... well, they were bad. In the late 90s and early 2000s, you basically had to make them yourself out of cardboard or sculpey if you wanted them to stay in your hair. Then came the official Gainax releases, which were often heavy and fell out if you moved your head too fast.
Today? It’s a totally different ballgame.
Companies like COSPA and various Etsy creators have perfected the weight-to-grip ratio. You can get them in high-grade matte resin, injection-molded plastic, or even 3D-printed versions with hand-painted weathering. Some high-end Japanese boutiques have even released "lifestyle" versions that are smaller and more subtle, meant for "stealth cosplay" at the office or a café.
Types of clips you'll find online:
- Official COSPA Headsets: These are the gold standard. They are sturdy, have the correct official dimensions, and use a strong spring clip that doesn't ruin your hair.
- 3D Printed DIY Kits: Great for people who want to paint their own or want a specific "battle-worn" look.
- Enamel Pin Variations: Not strictly hair clips, but many people use the same design as lapel pins.
- Light-up LED Versions: These are newer and honestly a bit bulky, but they look incredible for nighttime photography at cons.
The variety is actually staggering. You'd think there’s only one way to make a red triangle, but the texture matters. A glossy finish gives off a "New Movie" (Rebuild) vibe, while a matte finish feels more like the original 1995 TV run.
Why the Design Actually Works for Fashion
It’s the "if you know, you know" factor. That's the secret sauce.

If you walk down the street wearing a shirt with a giant screaming anime face on it, everyone knows you're an anime fan. It’s loud. But Neon Genesis Evangelion hair clips are different. To a "normie," they just look like some weird, avant-garde hair jewelry. Maybe something from a futuristic fashion line. But to another fan? It’s an instant signal. It’s a secret handshake.
The geometric shape fits perfectly into the "Cybercore" or "Techwear" aesthetics that have been blowing up on social media lately. Red is a power color. It pops against almost any hair color—blonde, black, brown, or even Asuka’s signature ginger.
Common Misconceptions About Wearing Them
One thing people get wrong is the placement. If you look at the character sheets from Studio Gainax (and later Studio Khara), the clips don't sit on top of the head like a headband. They sit slightly forward and to the sides, right where the A10 nerve would theoretically be accessed.
Also, they aren't meant to hold a lot of hair. If you try to use an interface clip to hold up a heavy ponytail, it’s going to snap or fly off like a projectile. Use a regular hair tie first. Then, clip the headset over the top for the look.
And please, don't buy the ones that are just flat stickers. I've seen them. They look terrible. The whole point of the Evangelion aesthetic is the industrial, "lived-in" machinery look. You want that 3D depth. You want the shadows that the recessed parts of the clip create.

Finding Quality Without Getting Ripped Off
Look, there’s a lot of junk out there. Since Evangelion is a global phenomenon, every factory from here to Tokyo is pumping out some version of these.
If you're buying on sites like eBay or AliExpress, look closely at the "vent" detail. Cheap versions often just have a sticker there or nothing at all. The high-quality ones have actual ridges or a separate piece of plastic to give it that mechanical feel.
Check the clip mechanism. If it’s a tiny, flimsy alligator clip glued onto the back with a glob of hot glue, it’s going to fall off within an hour. Look for "integrated" clips where the hardware is actually recessed into the mold. It makes a huge difference in how they sit flush against your head.
The "End of Evangelion" Impact
When the Rebuild movies finished with Thrice Upon a Time, there was a massive surge in interest for these accessories again. We saw new versions—specifically the ones Asuka wears in the final film with her white plugsuit. They have a slightly different, more refined silhouette.
It’s fascinating that a show about existential dread, giant monsters, and the "Human Instrumentality Project" has birthed such a persistent fashion trend. Maybe it’s because we all feel a little like we’re piloting a giant robot we don't understand sometimes. Or maybe it's just that red triangles look really cool in hair.
Actionable Tips for Your First Pair
If you’re ready to grab some Neon Genesis Evangelion hair clips, do it right. Don't just settle for the first $5 pair you see on a generic marketplace.
- Check the Weight: If the listing says they are made of solid metal, be careful. Metal clips are heavy and will slide down your hair unless you use an ungodly amount of hairspray. High-quality hollow plastic or resin is your friend.
- Match Your Era: Decide if you want the classic TV version (more "bulky" and hand-drawn looking) or the Rebuild version (sleeker, more technical).
- Secure the Base: Use "Bobby pins" in an X-shape underneath where you plan to put the clip. This gives the interface clip something to "bite" into so it doesn't move while you're walking.
- Consider the Color: While Asuka’s red is the icon, Rei’s white clips are much easier to pair with everyday "normal" clothes if you're worried about looking too much like you're in costume.
Go for the COSPA brand if you can find them in stock at places like AmiAmi or Mandarake. They hold their value and the color is exactly "Unit-02 Crimson," not just a generic bright red. If you’re going the handmade route, Etsy sellers like HenchmenProps or similar specialized cosplay creators usually offer way better durability than mass-produced versions. Get a pair, clip them in, and try not to start a Third Impact on your way to work.
