We're building hands-free, open-ear comms for rope teams. No buttons. No yelling. Just talk.
"Take!" · "Slack!" · "Watch me!" · "Off belay!"

The problem
01
Your hands are on the rock. Or on the rope. Push-to-talk is a joke the moment your next move is the hard one.
02
30 meters up, with a canyon breeze or a highway nearby, your belayer hears nothing. Not even close.
03
The guesswork that turns into near-misses. Every climber we've talked to has a story. Most have several.
How Oak works
Built so you never reach for it. Voice-activated, open-ear, noise-filtered — the only comms that disappears into your kit.
A single open-ear piece in one ear. Charging case holds a pair — one for you, one for your partner.
Voice activation means no buttons, ever. Wind and ambient filtering tuned for outdoor sport.
Open-ear design keeps you tied to your environment — rock, rope, rockfall warnings, partner commands.

Who it's for
We started with climbing because we live it. But the problem — hands busy, voice essential, environment-aware comms — shows up everywhere. We want to hear where it matters most to you.

Questions
We're validating the design with climbers right now. Production target is 2026. The early list gets the first units.
Rocky Talkies, Sena, and Cardo are push-to-talk radios. Great gear, but they all need a free hand. Oak never does. You never touch it mid-climb.
80m+ line of sight. Enough for single-pitch and most multi-pitch. Pitch-to-parking-lot is on the roadmap.
Yes — Oak meshes. Link up to a group of 6.
Oak is built by Ian Bernstein — a hardware operator who's shipped millions of units across previous consumer products, and a climber who was tired of yelling. Oak is the first product under his company, Idle Pines.
