Every AI hardware company is really making one bet: the form factor. Pins, pendants, glasses, cards, cubes. Most of them start from the hardware and look for a use case.

We started from the use case. If you're going to talk to agents all day, what does the interface actually need to do?

It needs to hear you clearly, anywhere. It needs to talk back without broadcasting to the room. It needs to let you check on and steer your agents without pulling out a phone. And it needs to be something you'd wear all day without thinking about it.

Our answer is two small things: a pair of earphones and a ring.

Why earphones?

The hardest thing in consumer hardware isn't the technology. It's getting people to wear something new. Earphones skip that problem entirely. People already wear them for hours a day – roughly 90 million pairs of true wireless earbuds shipped in a single quarter last year. Nobody needs to be convinced to put them in.

They also sit in exactly the right place. Your ears are where answers come in, and they're a few centimeters from where your words go out. A pin on your chest or a pendant around your neck is further from your mouth and closer to everything else.

And they're private. Audio plays only to you. With real voice isolation, you can speak at a normal volume – or quieter – in a café or on a train, and your agent hears you, not the room. There's no camera pointed at anyone and nothing for the people around you to worry about.

Why a ring?

Voice is great for telling an agent what to do. It's clumsy for everything around that. Saying "switch to the other agent" or "yes, approve that" out loud in a meeting doesn't work.

The ring started as a simple controller for the earphones. Then our early users showed us the real problem. Agents run long tasks, so people switch away to something else. When they come back, the agent stopped twenty minutes ago, waiting for a permission or a question. And most of them run several agents at once.

So the ring became the control layer. It buzzes when an agent needs you, shows you which one, and lets you tap, hold or swipe to approve, switch or start talking – without touching your ear or reaching for your phone. Your hand is always with you, and a thumb against a finger is about the most natural gesture there is.

Why not glasses, a pin or the phone?

Glasses are the closest competitor, and they've sold well. But putting a camera on your face brings everyone around you into it. Some venues have started restricting them – DEF CON banned Meta's glasses this year over unauthorized recording. Plenty of people also simply don't wear glasses, and won't start.

Pins and pendants have the opposite problem. The mic is too far from your mouth to hear you in a noisy room, and a speaker on your chest isn't private. We've already watched that bet play out.

And the phone is what we're trying to free you from. Every time you pull it out to check on an agent, you've lost the moment you were in.

Earphones for your voice. A ring for control. Two devices people already know how to wear, each doing one job really well. That's the right form factor – not because it's new, but because it isn't.
