Wearable technology has spent too long looking like wearable technology. Slac breaks that mold with a refreshingly honest approach: if something lives on your body all day, it should look like it belongs there. The circular ear ring and accompanying wrist piece read more like contemporary jewelry than consumer electronics, which is exactly the point.
This concept taps into how Gen Z actually relates to their audio devices. These aren’t tools you begrudgingly carry. They’re expressions of taste, mood shapers, and now with Slac, genuinely attractive accessories. The open hoop design that hugs your ear offers a sculptural quality that traditional earbuds simply can’t match. When paired with the sleek wrist component, you get a cohesive audio system that understands fashion and function aren’t opposing forces. They’re partners in creating technology people actually want to wear.

Three components make up the full system: an open ear ring handling audio output, a wrist-worn ring tracking your listening data, and a home charging station. That circular form factor pulls double duty in ways most earbud designs completely miss. Wrapped around your ear, it creates this architectural presence without jamming anything into your ear canal. You stay aware of conversations, traffic, your entire sonic environment while your music layers on top. When you’re done listening, the ear ring snaps magnetically onto the wrist component, transforming the whole setup into what reads as a chunky watch band or bracelet. Nobody’s shoving these into a pocket case like loose change.
The AI running behind the scenes tracks your full 24-hour audio cycle and starts building preference profiles automatically. Machine learning analyzes sound intensity, pitch variations, and tonal characteristics from everything flowing through those ear rings. Cycling to work means you probably want traffic noise punched up alongside your playlist. Grinding through spreadsheets at a coffee shop means the background chatter gets filtered while your focus playlist stays crisp. The system generates these sound filtering categories in real time, and you can tweak individual layers through sliders in the app. Boost voices, drop mechanical hum, amplify nature sounds, whatever combination your brain needs in that specific moment.
They’ve included this gesture control called “Slate” that actually seems thought through. You rotate your hand in a circular motion while wearing both rings, mimicking that clapperboard snap before a film take. One rotation flips you between content-focused mode and environment-focused mode. Your podcast drops to background levels while street sounds come forward, or vice versa. No app diving, no button fumbling, just a quick physical gesture.
The aesthetic commits fully to the jewelry angle without hedging. Both black and metallic colorways show up in the renders, and that wrist component carries enough visual mass to register as intentional rather than apologetic. You could wear this setup to contexts where regular earbuds feel socially awkward. Dinner with your partner’s parents, a work presentation, anywhere those telltale white stems signal that you’re half-checked-out. This project emerged from a design team working within Samsung’s development programs, and you can feel years of wearable experience informing every choice. Slac points toward where personal audio needs to go: context awareness, all-day wearability, and designs that enhance your aesthetic rather than forcing compromises.
Will this exist any time soon? I honestly doubt it. A lot of these large-scale internship/incubation programs are aimed at imagining an alternate reality or future and working to build the technology in that direction, in the hopes that insights and innovations will trickle into existing products. The Slac, as we see it, probably won’t exist… but its overarching theme of technology as jewelry is already fairly popular. Smartwatches and AI Pins are a great example of this, and given how often we already wear TWS earbuds, the idea of an earbud that also masquerades as jewelry seems like a fairly clever route…
