How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want the familiar, bass-forward Beats sound and don't mind a renewed unit with a 90-day warranty, choose Amazon Renewed Powerbeats3; if you need an open-ear design that keeps you aware of traffic on every run, choose Jamsync Open Ear Headphones.
• Amazon Renewed Powerbeats3 — biggest strength: a true in-ear, sealed fit with 12 hours of battery life and Siri/control support, which is what a lot of runners still prefer for locked-in sound.
• Amazon Renewed Powerbeats3 — biggest trade-off: these are in-ear and noise control is listed as "None," so they plug your ear canal rather than let sound in — and they're a renewed product, which means a 90-day warranty instead of a full new-unit one.
• Jamsync Open Ear Headphones — biggest strength: an open-ear design (22g, IPX5, 14-hour battery, Bluetooth 5.4) built specifically so you hear cars and cyclists while you run.
• Jamsync Open Ear Headphones — biggest trade-off: open-ear means you don't get sealed, isolating sound, and there's no noise control listed — the audio is deliberately leaky so the world stays audible.
• Who each is for: pick the Powerbeats3 if you want in-ear bass and a classic sport earbud; pick the Jamsync if awareness and all-day comfort matter more than isolation.
The Powerbeats3 is the in-ear option here, and that single design fact drives everything else. The earbuds sit inside your ear canal, which is the setup many runners reach for when they want their music to feel present and full rather than ambient. It's a wireless Bluetooth model with a control type that includes Siri, so track skipping and voice commands are handled without pulling out your phone mid-stride. Battery life is listed at 12 hours, which comfortably covers a week of short runs or a couple of long ones before you need to charge.
Who should skip it? Anyone who needs to stay aware of their surroundings while running. There's no noise control listed, and the in-ear placement naturally blocks some ambient sound — which is exactly the opposite of what a road runner dodging traffic wants. If safety awareness is your priority, the Jamsync is the better tool for the job. Also skip it if a 90-day warranty feels too short for your comfort level.
Jamsync Open Ear Headphones: Who It's For
The Jamsync is built around one idea: keep your ears open. It's an open-ear design, meaning the drivers rest outside your ear canal rather than sealing it, so traffic, cyclists and announcements stay audible while your playlist plays. That's the whole reason this category of running headphone exists, and it's what makes the Jamsync the more safety-conscious pick of the two. The fit is a wrap-around silicone frame at just 22 grams, which the specs describe as staying planted through sprints, box jumps and long rides, with no pressure points or ear fatigue.
The numbers are genuinely strong for the category. Battery life is listed at 14 hours of continuous playback, charged through a sealed magnetic port that keeps moisture out — no exposed port and no rubber plug to lose. It's rated IPX5 for water resistance, so sweat and light rain are within its comfort zone. Bluetooth 5.4 handles pairing and multi-point connectivity, so you can switch between your phone and laptop, and there's a built-in mic tuned for active use — the spec sheet is upfront that it's meant for quick check-ins, not studio calls, and that there's no noise cancellation by design.
Buy it if you run outdoors, commute by bike, or train in a gym where you still want to hear what's around you. It's also the pick if you hate the plugged-up feeling of in-ear buds. Skip it if you want deep, isolating bass — the Jamsync's own specs admit the sound is "not audiophile-grade sealed sound," because open-ear audio always leaks. If you need maximum isolation, this isn't the design for you.

For running specifically, I'd buy the Jamsync Open Ear Headphones. In my opinion, the open-ear design is the deciding factor: hearing traffic while you run isn't a nice-to-have, it's the thing that keeps you safe on the road, and the Jamsync is engineered around exactly that. Add the 14-hour battery, IPX5 rating, 22g frame and 12-month warranty, and it's the more purpose-built running headphone of the two. I'd only pick the renewed Powerbeats3 if you already love that in-ear Beats sound and don't need to hear your surroundings.
FAQ
how to wear running headphones
how to run with headphones
Get a secure fit before you start, keep the volume low enough that you can still hear what's around you, and route the cable or set the controls so nothing dangles. The Jamsync's open-ear design is the safer choice outdoors because it leaves your ears open to traffic; the in-ear Powerbeats3 blocks more ambient sound, so stay extra aware.
how to run without headphones
Some runners go without entirely — no fit issues, no battery to manage, full awareness of your surroundings. If you want music but still want that open, aware feeling, an open-ear model like the Jamsync is the closest compromise, since it keeps your ears uncovered rather than sealed.
how to connect shokz running headphones
Connecting a bone-conduction or open-ear running headphone is the same basic process: put the headphone in pairing mode, open your phone's Bluetooth settings, and select the device. The Jamsync uses Bluetooth 5.4 with multi-point connectivity, so it pairs quickly and can hold a connection to two devices at once.
