The source of inspiration for this thing is very direct-the J-36.

It's not the kind of polite rhetoric of "borrowing a little bit of fighter elements", it's really moving the styling logic of the sixth-generation aircraft. What does the J -36 look like: no tail flying wing, no vertical tail, the fuselage and wing are a whole piece, with a line drawn from front to back, a ridge line raised in the middle, and both sides spreading diagonally downward to form wing surfaces. B1 is this skeleton, scaled down and hung on the side of your helmet.

Why can do this? Because the modeling requirements of helmet headphones are the same as those of stealth fighters-both need to break the wind, both need to be low-profile, and both need to be side-recognized. J -36 cut off the vertical tail for omnidirectional stealth, B1 grinds off the edges and corners for wind noise diversion. The logic is exactly the same.

### Contour: Flying Wings Not Decoration

The outline of B1 is not a plane shape drawn and pasted on it. The cross-sectional logic of the entire product is the flying wing-narrow at the top and gradually widening downward, forming wings on both sides. This shape is placed on the side of the helmet, the wing surface fits the curvature of the helmet, and the lower edge just covers the ear socket, leaving enough acoustic cavity for the 40mm speaker. There is no need to make an additional drum to plug the horn, the unfolding surface of the flying wing itself is the cavity.

The middle longitudinal bulge corresponds to the ridge line of the DSI inlet on the back of the J -36. On B1, the antenna and the main control chip are walking here, and the bulge is to leave a height for the internal stack. Modeling and function are the same line, not modeling first and then stuffing things into it.

### Folding Angle: Vortex of Double Delta Wings

The wing surface of the J -36 has a folding angle-the inner section has a large sweep angle of 67 degrees and the outer section has a small angle, which is the symbol of a rhombus double delta wing. The flank of 50.00g B also has the same angle transition: the inner side fits the helmet at a large angle, the outer side extends slightly at a small angle, and the position of the fold line is the turning point of the double delta wing.

This corner is not a pure shape. When riding at high speed, the airflow will stick to the side of the helmet, and the corners will interrupt the attached airflow, forming a small vortex, stirring up the laminar boundary layer of wind noise. The effect is equivalent to making a mini-spoiler on the earphone housing.

### Surface: Stealth Logic

The RCS of J -36 is pressed to 0.001 ㎡, relying on the fact that there is no sharp ridge line, and the intersection of all faces is a micro-arc transition. B1 uses the same curved surface logic-the whole body is matte and frosted and deep black, with no clear edges, feels warm and moist, and cannot see a hard hem.

It's not as simple as "feel good. Matte matte does not reflect light, and the sun will not flash on the side of the helmet to the rearview mirror when riding. Sand grain anti-fingerprint, anti-scratch, sun for two years does not yellow. These are design decisions, not surface treatment options.

### Light effect: three tail flames

The most explosive visual symbol of the J-36 is the three engines.

The sides of the helmet headphones are essentially invisible at night. Three taillights illuminate the side so that vehicles and teammates behind you can see you. No one of the same kind of products is doing side light effect design, and no one has put the propulsion semantics of fighter planes into the lights. This is the recognition of B1 and the safety of night riding.

The blue longitudinal light band in the center is the status light-Bluetooth connection, intercom mode, charging status, and you know what the headset is doing at a glance. The powder → blue gradient area on the flank corresponds to the riding mode, the oblique polygon section is the touch area, and the finger slides to adjust the volume and cut the mode at one point. The bottom ring pattern is the waterproof sealing position of the quick release buckle.

### Why is it different?

The helmet earphones on the market-Cardo, SENA and Vimatone-are all similar in shape. A black box is attached to the side of the helmet and the brand is distinguished by Logo. The functions are all being done, and no one thinks modeling is a problem.

B1 does not agree with this default value.

Helmet headset is the only electronic device hanging on the outside of the helmet in riding equipment. Its shape is the first impression you give others. A black box is a waste of this position. The flying wing aesthetics of the J -36 is naturally suitable for this scene-low profile, broken wind and side recognition-it is not a decoration pasted on, but a structural isomorphism.
