• Puro Sound Labs — biggest strength: hard 85 dB volume limit plus a Balanced Response Curve, so kids get full bass and clear vocals without you worrying about their hearing.
• Puro Sound Labs — biggest trade-off: it is passive noise cancellation only and tops out at 20 hours per charge, so it will not silence a loud environment.
• Avantalk Avantree Sky Infinity — biggest strength: true Active Noise Cancellation with a Qualcomm chip, aptX Adaptive audio, Auracast, and two pairs of earbuds you can swap to keep going.
• Avantalk Avantree Sky Infinity — biggest trade-off: in-ear fit and a 3-hour charge time mean more fiddling, and there is no 3.5 mm jack on the buds themselves.
• Who each pick is for: Puro for parents buying safe listening for kids; Avantree for travelers and anyone sharing audio on a plane or at home.
The Puro Sound Labs BT2200 Plus is a kids-first headphone, and it never pretends otherwise. The headline feature is the 85 dB volume limit. That number is the whole point. It caps output at a level widely treated as safe for extended listening, which means a child can wear these through a long car ride, a quiet afternoon on the dock, or a rainy day indoors without you hovering. The Balanced Response Curve is the second piece: instead of just muffling everything to hit that limit, Puro tunes the driver so bass and vocals still come through. Dynamic drivers with a 20 Hz to 20,000 Hz range cover the full audible spread.
Comfort is where this thing earns its keep for families. The earpads are soft and breathable, and the earcups rotate and adjust. You get both on-ear and over-ear cushions in the box, so a smaller kid and an older one can each find their fit. That matters on a boat or in a tent, where a headphone that pinches gets ripped off in ten minutes. The build is faux leather, the color here is teal, and the whole package is lightweight enough for all-day wear.
Battery is a clean 20 hours, and charge time is listed at 20 hours as well — so plan on charging overnight, not mid-trip. Bluetooth 5 gives you roughly 30 feet of range, which is plenty when the phone is in a dry bag a few feet away. The built-in mic handles calls. You also get a 3.5 mm jack, which is genuinely useful: no battery, no pairing, just a cable when you want zero fuss.
Who should buy it: parents and gift-buyers who want safe, comfortable, no-drama headphones for a child, and who value the wired option and the dual-listening cable. Who should skip it: adults who want real noise cancellation, or anyone who needs to block out a genuinely loud environment. Passive noise cancellation only means it reduces some ambient sound through the seal, nothing more. It is not a tool for silencing a noisy cabin.
Avantalk Avantree Sky Infinity: Who It's For
The Avantree Sky Infinity NC is aimed at a completely different buyer. This is a travel kit disguised as earbuds. Two things define it. First, Active Noise Cancellation driven by a Qualcomm chip, which the brand describes as cutting the large majority of engine and cabin noise. Second, the bundled Relay Transmitter — a plug-and-play Bluetooth dongle that connects to an airplane seat screen or any AUX output, so you can wirelessly listen to in-flight entertainment. If you have ever fumbled with a flimsy airline adapter, this is the fix.
Then there is the two-pair trick. The box includes two pairs of Infinity NC earbuds. Use one while the other charges in the case, and swap whenever you like. For a long-haul flight or a full day of moving around, that effectively removes the battery-anxiety problem without needing to sit tethered to a wall. The case itself is compact and slides into a travel bag.
Sound is handled by Qualcomm aptX Adaptive, with support for aptX Low Latency, aptX HD, aptX and SBC. That is a broad codec spread, and aptX Adaptive is the interesting one: it adjusts to deliver deep bass, clear vocals, and low latency, which keeps audio and video lined up. Bluetooth 5.3 with a stated range of up to 33 feet covers phone, tablet, and laptop use. Each earbud pairs independently, so this is not a flight-only gadget — it is a daily driver too.
Auracast is the forward-looking piece. With LE Audio broadcasting, you can join public audio streams in airports, gyms, museums, or conference halls without pairing — tap and listen. That is a technology bet on where public audio is heading, and it is rare to see it in a mainstream pair of earbuds.
Controls are touch-based, and there is no headphone jack on the earbuds. Charge time is listed at 3 hours. You get four extra pairs of earbud tips, which is important for in-ear fit, since a proper seal is what makes ANC work well. Warranty runs 24 months with product registration, plus chat, email, and phone support.
Who should buy it: frequent flyers, couples or friends who want to share one audio source, commuters who need real noise cancelling, and anyone curious about Auracast. Who should skip it: parents shopping for a young child, since there is no volume limit and the in-ear design is a poor fit for small ears.
• Best for hearing safety with kids → Puro Sound Labs. The 85 dB cap is the deciding spec, and nothing on the Avantree side replaces it.
• Best for noise canceling → Avantalk Avantree Sky Infinity. Active Noise Cancellation versus passive isolation is not a close contest in loud spaces.
• Best for sharing audio → tie, but differently. Puro shares via a daisy chain cable to one device; Avantree shares via two earbuds on one transmitter. Cable versus wireless, same idea.
• Best for flying → Avantalk Avantree Sky Infinity. The bundled transmitter and ANC are built for exactly that scenario.
• Best for a wired fallback → Puro Sound Labs. A 3.5 mm jack means it works with no battery at all; the Avantree earbuds have no jack.
• Best for all-day comfort on a kid → Puro Sound Labs. Rotatable cups plus interchangeable on-ear and over-ear cushions are hard to beat for growing heads.
• Best for codec quality → Avantalk Avantree Sky Infinity. aptX Adaptive and aptX HD outclass plain Bluetooth 5 audio.
• Best for battery convenience → Avantalk Avantree Sky Infinity. Two swappable earbud pairs beat a single 20-hour charge when you cannot stop to plug in.
For most people reading this, the honest answer depends on who is wearing them. If I were buying for a child — for a family fishing weekend, a long drive, or everyday listening — I would buy the Puro Sound Labs BT2200 Plus. The 85 dB limit is a real safety feature, the fit options are generous, and the daisy chain cable solves the two-kids-one-tablet problem cleanly. If I were buying for myself as a traveler, I would buy the Avantree Sky Infinity NC. Active noise cancelling, the airplane transmitter, and the second pair of earbuds are a genuinely useful combination for flights and commutes, and Auracast makes it feel current. Match it to the wearer, not to the spec sheet.
FAQ
Yes. It uses Active Noise Cancellation built around a Qualcomm chip to reduce engine and cabin noise. That makes it the stronger pick when you want to block out a loud environment, whether that is a plane, a bus, or a noisy dock.
Both can do it, in different ways. Puro includes a daisy chain cable that links two headphones to a single device. Avantree includes two pairs of earbuds that both pair with the same transmitter, so two people share wirelessly with no cable between them.
The Avantree Sky Infinity is the more natural fit for active use — it is in-ear, lightweight, and comes with extra tip sizes for a secure seal. The Puro is on-ear/over-ear with a headband, so it is better suited to sitting still than to casting and moving around.
