What people
are saying
I like them, I ran with them...I like the fit... I have the smallest ears ever, nothing feels comfortable on them. But, these are so good!
LOVE THEM!! Super lightweight, great sound, open ears. I don't like running with earbuds because I lose situational awareness, and that's very important to me, otherwise I get bad anxiety. With these, my ears are open and I can hear everything around me AND my music at all times.
They live on my desk, I put them on the moment I sit down, and I forget they are there until I am done for the day. That is the entire point. And the Fusion nails it in ways I did not expect.
Zero Canal. Full Awareness.
Open-Ear Design. World On.
Most headphones block the road out. That's when runs get dangerous.
Open-ear means your music plays while the street stays real. Bonic Fusion Open Ear Running Headphones keep your ears free from canal contact, helping reduce the feeling of trapped heat and discomfort. No wax buildup mile after mile. Just music layered over the world, so you can enjoy your sound and stay aware of your surroundings, exactly the way it should be.
That’s the difference with lightweight open ear headphones they stay out of your way while you stay aware, comfortable, and completely in control of every step.
Put It On. Forget It's There.
Gear that fights you doesn't make the run — it ends it.
At 27g, it disappears once it's on. Silicone that won't freeze in January or warp in July. A wraparound fit that holds from the first step to the last. No bounce. No fidgeting. Nothing between you and the miles.

FAQs
Please read our FAQs page to find out more.
How does Bonic Fusion differ from Bonic Cycle?
Same core tech — open-ear design, IPX8 waterproofing, silicone build — but lighter at 27g and available in four city-inspired colorways. Built for lit environments and daytime running. If you run in low-visibility conditions at night, our LED-equipped model is the better fit.
Will these stay on during a workout?
The memory metal frame flexes to your head shape and locks in place — no slipping through trail runs, cycling sprints, or gym sessions. For very small or large head sizes, reach out and we'll help you find the right fit.
Is open-ear better for your ears?
Traditional in-ear buds sit inside the ear canal, trapping heat and moisture. Over time, this can contribute to excess wax or discomfort.
Bonic rests on the outer ear, leaving the canal completely open — no contact, no buildup.
Is open-ear safe near traffic?
Open-ear headphones are designed to let you stay aware of your surroundings while listening. Sealed in-ears block the cars, bikes, and voices you need to hear. Bonic Fusion keeps you fully aware of your surroundings while you listen — music and environment, at the same time.
Can I wear these in cold weather?
Yes. The silicone cover is specifically designed to stay flexible in low temperatures. Hard plastic shells can crack or stiffen in freezing conditions — silicone doesn't. Comfortable in winter training
conditions.
