If you want open-ear, sweat-proof audio for running and workouts, choose SHOKZ After Aeropex; if you need a portable speakerphone that makes conference calls sound professional, choose Jabra Speak 510. These two products share almost nothing except Bluetooth — one is worn on your head, the other sits on a table — so the "better" pick depends entirely on what you're actually trying to do.
• SHOKZ After Aeropex — biggest strength: Bone conduction drivers sit on your cheekbone and leave your ears completely open, so you stay aware of traffic, teammates and surroundings while you run or ride.
• SHOKZ After Aeropex — biggest trade-off: Open-ear listening means you'll never get the isolation or bass of sealed headphones, and at roughly 25.5 g it's a sport-first device, not a meeting-room tool.
• Jabra Speak 510 — biggest strength: A 50 mm dynamic driver in a 10-watt stereo speakerphone with a built-in mic, USB and Bluetooth, so one puck handles calls across laptops, phones and desk phones.
• Jabra Speak 510 — biggest trade-off: It's a tabletop speaker (about 195 g, roughly 4.7" square), not something you wear — useless for a run, and it needs a flat surface to do its job.
• Pick SHOKZ After Aeropex if you're buying for your own ears: workouts, running, cycling, podcasts on the move.
• Pick Jabra Speak 510 if you're buying for a room: conference calls, hybrid meetings, a small team huddle, or hands-free calling at a desk.
The AfterAeropex is the cleanest expression of what SHOKZ does. Its bone conduction driver sends audio through your cheekbone, and the wrap-around, bud-free design means nothing ever enters your ear canal. If you've ever pulled earbuds out mid-run because they kept slipping or your ears started aching, that design choice is the whole point. The spec sheet backs it up: an open-ear placement, a claimed 8 hours of playback, and an IP67 waterproof rating that covers sweat, rain and everything short of swimming — SHOKZ explicitly notes these aren't for the pool. There's even a moisture-detection alert that stops charging if the contacts are wet, which is the kind of small detail that tells you this was designed by people thinking about sweaty humans.
Comfort is the other pillar. At roughly 25.5 grams, this is a device you can genuinely forget you're wearing, and the "pain-free, all-day" framing in the specs isn't marketing fluff — no bud means no pressure inside the ear, which is exactly where most sport headphones fail over a long session. Bluetooth 5 with multipoint pairing lets it hold two devices at once, so you can jump from a laptop call to your phone without re-pairing. A single multifunction button handles play, pause, skip, voice assistant and call answering, and dual noise-cancelling mics handle your voice on calls. You also get touch and voice control, a 10-meter Bluetooth range, and a two-hour charge time to full.
Who should buy it: runners, cyclists, gym-goers, and anyone who wants music or podcasts while staying aware of what's happening around them. It's also a strong pick for people who find in-ear buds uncomfortable or who ride on roads where hearing traffic matters.
Who should skip it: anyone who wants deep bass and total isolation, anyone who needs a speakerphone for meetings, and anyone who wants to swim with their headphones — IP67 covers sweat and rain, not submersion. And if you're shopping for a group rather than yourself, this is the wrong category entirely.
The Speak 510 is a different animal: a portable conference speakerphone built for calls you take with other people. Its job is to make you sound clear and to make everyone in the room sound clear back. The hardware reflects that — a 50 mm dynamic driver, 10 watts of output, stereo playback, and a single built-in microphone, all packed into a tabletop puck about 4.7 inches square and 1.3 inches tall. It's light enough to toss in a bag with the included travel pouch, but at roughly 195 grams it's meant to sit on a desk, not live in your pocket.
The connectivity is the real selling point. It does Bluetooth and USB, so you can pair it wirelessly to a phone or plug it directly into a laptop for a more stable connection. Jabra lists it as working with Microsoft Teams and all the major online meeting platforms, plus desk phones, mobile phones and softphones — which matters if your "office" is a rotating cast of a work laptop, a personal phone and whatever conference room you've booked. Bluetooth range is quoted at up to 100 feet, so you can walk to the whiteboard without dropping the call.
Battery life is where it quietly outclasses the SHOKZ: 15 hours of average use versus 8, with the same 2-hour charge time. Setup is described as near-instant — pair or plug, and you're live. Controls are handled through a touchpad on top, so muting and volume are one tap away. It is not waterproof, and it's not something you'd wear, so treat it as a room device and it performs exactly as intended.
Who should skip it: runners, gym users, and anyone shopping for personal listening. It's also the wrong choice if you need serious bass or private audio — it broadcasts to the room, which is the entire point and also the entire limitation.
Side-by-Side: Which Should You Choose?
• Best for workouts and running → SHOKZ After Aeropex. Open-ear bone conduction and IP67 sweat/water resistance are built exactly for this.
• Best for conference calls and meetings → Jabra Speak 510. A 10-watt speakerphone with a built-in mic and Teams compatibility is purpose-built for it.
• Best battery life → Jabra Speak 510, with a claimed 15 hours versus 8 hours on the AfterAeropex.
• Best for staying aware of your surroundings → SHOKZ After Aeropex. Open-ear placement is the core design, not a side feature.
• Best for connecting to many device types → Jabra Speak 510. Bluetooth and USB, plus desk phone, mobile and softphone support.
• Best for all-day personal comfort → SHOKZ After Aeropex. Roughly 25.5 grams and bud-free, so nothing presses into your ear canal.
• Best for travel where you need a room-filling call → Jabra Speak 510. Portable, pouch included, up to 100 ft Bluetooth range.
• Best for noisy or wet environments on your head → SHOKZ After Aeropex. IP67 handles rain and sweat; the Speak 510 is not waterproof.
If I had to buy one, I'd buy the SHOKZ After Aeropex — but only because my use case is personal audio on the move, and open-ear bone conduction solves a problem (hearing your surroundings while running) that no speakerphone can touch. That said, this is genuinely a category question, not a quality question. If your days are full of calls and you need the room to hear you, I'd take the Jabra Speak 510 without hesitation: 15 hours of battery, USB plus Bluetooth, and a 10-watt speaker made for voices. Buy the one that matches your actual day, and check the current price on Amazon before you commit.
Yes — it carries an IP67 waterproof rating, which covers sweat and rain. Note the specs say it's not suitable for swimming, and a moisture-detection alert prevents charging while the contacts are wet. For road running and gym sessions, it's built for exactly that.
Yes. It's a stereo speaker with a 50 mm dynamic driver and 10 watts of output, and Jabra lists streaming music among its uses. It's tuned for clear voice, so don't expect audiophile bass — but it works fine for background music between meetings.
The Jabra Speak 510 lasts longer on paper: a claimed 15 hours versus 8 hours for the AfterAeropex. Both take about 2 hours to charge. For a full day of calls the Jabra wins; for a week of runs the SHOKZ is plenty.
For most people, no — they solve completely different problems. Only buy both if you genuinely need open-ear audio for workouts and a dedicated speakerphone for work calls. Otherwise, match the product to the job you do most and skip the other.
