If you want a refined everyday pair whose ambient mode you can fine-tune in granular steps — and you're mostly worried about staying aware of a toddler in the next room while you listen — choose Sony WF-C710N; if you need a rugged, sport-first set with big battery numbers, a harder-shell travel case and an ambient mode built around workouts, choose JBL Endurance Race 2.
• Sony WF-C710N — biggest strength: Ambient Sound Mode with 20 adjustable levels plus a Focus on Voice setting, backed by Sony's Sound Connect app, so you control exactly how much of the room you let in.
• Sony WF-C710N — biggest trade-off: IPX4 only, so splashes and sweat are fine but heavy rain or full submersion are not part of the deal.
• JBL Endurance Race 2 — biggest strength: Up to 48 hours of total playback, IP68 waterproof and dustproof construction, and 4 beamforming mics for calls.
• JBL Endurance Race 2 — biggest trade-off: Smart Ambient is a simpler on/off-style awareness control with no multi-level slider, so it's less granular than Sony's approach.
• Who Sony is for: commuters, remote workers, parents keeping one ear on the house.
• Who JBL is for: runners, gym-goers and anyone who treats earbuds as workout gear first.
The WF-C710N is built around control. Ambient Sound Mode uses dual mics to pull the outside world into your ears, and the Sony Sound Connect app lets you dial that in across 20 levels. There's also a Focus on Voice setting, which is the feature I'd point at if you're the kind of person who keeps earbuds in while a small child is running around nearby — you can hear a voice without pulling anything out of your ears. That's the practical version of "ambient mode for toddlers": you keep your audio, you keep your awareness.
The rest of the package is quiet, competent everyday listening. Active Noise Cancelling with Dual Noise Sensor technology handles the other direction — when you want the room gone. Battery is rated up to 8.5 hours in the buds and up to 21.5 hours in the case, which Sony totals at up to 30 hours, and a 5-minute quick charge gets you up to an hour of playback. Multipoint connection pairs two Bluetooth devices at once, so a call on your laptop interrupts your phone's music and hands it back when you're done. The 5 mm dynamic driver plus DSEE processing is tuned for strong bass and clear vocals rather than studio flatness.
Who should buy it: people who want an ambient mode they can actually tune, who take calls in noisy places, and who want a lightweight, compact in-ear bud (5.2 g) that disappears in a pocket. The cylindrical case is small on purpose. IPX4 covers sweat and splashes, Bluetooth 5.3 covers the connection. Who should skip it: anyone who needs a waterproof rating for swimming or soaking rain, and anyone who wants the longest possible battery number on paper.
JBL's Endurance Race 2 is a sport bud that happens to do awareness well. Smart Ambient lets you decide how much of the outside world you hear so you can talk to someone or stay alert without removing the earbuds — exactly the behavior you'd want while jogging through a busy park. The difference from Sony is depth: this is a simpler control, not a 20-step slider, and there's no equivalent to a Focus on Voice toggle listed in the specs.
What it does have is endurance. Up to 12 hours in the buds plus another 36 hours across three full case charges gets you to 48 hours total, and 10 minutes on USB-C buys up to 4 more hours with ANC off. Active Noise Cancelling is here too, so the same buds that let the world in can also shut it out. Four mics — two beamforming mics per bud — handle calls, with the design intent being clear speech even in a breezy, busy outdoor setting. The 6.8 mm dynamic drivers push JBL Pure Bass, and an IP68 rating means dust and water are genuinely not a concern. Sports Mode settings live in the JBL Headphones App.
The bundle matters here: you also get an Expo Gear weather-resistant hard-shell case with a mesh pocket, zipper closure and a carabiner. It's a travel and storage solution, not a throwaway pouch, and the carrying case measures roughly 7 cm by 43.1 mm by 30.5 mm at 41.1 g — small enough to clip on a bag.
Who should buy it: runners, gym regulars, cyclists and anyone whose earbuds live in a backpack. Who should skip it: people who want granular ambient tuning, and anyone who prefers the lightest possible bud — at 53.9 g for the bundle, this is a heavier kit than a bare earbud set.
• Best ambient control → Sony WF-C710N. 20 adjustable levels plus Focus on Voice, all in the Sound Connect app.
• Best for workouts and weather → JBL Endurance Race 2. IP68 waterproof and dustproof versus IPX4 splash resistance.
• Best battery endurance → JBL Endurance Race 2. Up to 48 hours total against Sony's up to 30 hours.
• Best for calls in noisy places → Sony WF-C710N. Precise Voice Pickup Technology with AI-based noise reduction and voice extraction.
• Best for switching between laptop and phone → Sony WF-C710N. Multipoint connection is listed; the JBL sheet does not list it.
• Best travel kit out of the box → JBL Endurance Race 2. The bundle includes a hard-shell case with mesh pocket and carabiner.
• Best for keeping an ear on the house → Sony WF-C710N. The 20-level ambient slider and Focus on Voice are what you want when a toddler is asleep down the hall.
• Best fit for sport-specific tuning → JBL Endurance Race 2. Sports Mode settings in the JBL Headphones App.
If you're hunting for the best sports earbuds for toddlers in the sense of gear that survives being grabbed, dropped and rained on while you chase one around, the JBL's IP68 shell and hard case are the more forgiving combination. If your version of that search is really about hearing your kid while you listen, Sony's ambient system is the more precise tool.
In my opinion, I'd buy the Sony WF-C710N. Ambient sound mode is the whole point of this comparison, and Sony is the one that treats it as a real feature: 20 levels, a Focus on Voice setting, and an app to tune it. For parents keeping half an ear on a toddler while working or commuting, that granularity is the difference between useful and gimmicky. I'd only switch to the JBL Endurance Race 2 if my priority were surviving sweat, rain and dust with 48 hours of playback — that's a genuinely better workout bud, but a blunter ambient tool.
what is ambient mode on earbuds
Ambient mode uses microphones on the earbuds to feed outside sound into your ears instead of blocking it. On the Sony WF-C710N, dual mics capture surrounding sound and the Sound Connect app lets you adjust how much comes through across 20 levels.

It's the same idea under a different name — a transparency setting that keeps you connected to your environment while you listen. JBL calls its version Smart Ambient, letting you control how much of the outside world you hear while keeping the earbuds in.
what is ambient mode in earbuds
Simply put, it's awareness mode: you hear your music and your surroundings at the same time. Sony adds a Focus on Voice option for chatting without removing the earbuds, while JBL frames Smart Ambient around talking to others or staying alert.
For control, yes — in my opinion Sony's 20-level ambient adjustment and Focus on Voice setting give you finer tuning than JBL's Smart Ambient. For durability and total battery life, the JBL Endurance Race 2 with IP68 and up to 48 hours is the stronger pick.
Neither of these is an ear clip design — both are in-ear buds, so that's a different category. Between these two, I'd pick the Sony WF-C710N if awareness is the goal, and the JBL Endurance Race 2 if ruggedness is. Check the current price on Amazon before deciding.
