How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want proven hearing protection with active noise cancelling and a 22-hour battery, choose Puro Sound Labs; if you need the longest battery life, fun LED customization and the newest Bluetooth, choose MEE audio KidJamz KJ55BT.
• Puro Sound Labs – biggest strength: a full safety package — 85 dB volume limiting, hybrid active noise cancelling, and up to 87% ambient noise isolation. Biggest trade-off: the shorter 22-hour battery and an older Bluetooth 5.1 spec.
• MEE audio KidJamz KJ55BT – biggest strength: up to 40 hours of playtime, Bluetooth 5.4, and LED ear-cup graphics with eight color patterns. Biggest trade-off: no active noise cancelling — just passive sound isolation.
• Pick Puro Sound Labs if your priority is quieting a noisy world for your kid while still capping volume.
• Pick MEE audio KidJamz KJ55BT if your priority is marathon battery life, wired backup, and a headset your kid actually wants to wear.
Puro Sound Labs built the JuniorJam Plus around one idea: keep the volume safe without making the sound boring. The limiter caps output at 85 dB, which is the level widely recommended for kids' listening. Instead of just clamping the volume and leaving you with thin, tinny audio, Puro pairs the limiter with its Balanced Response Curve — the result is a claimed hi-res listening experience with solid bass and clear detail. On paper, the 32-ohm impedance and 20 Hz–20 kHz frequency range are standard for kid-friendly dynamic drivers, so the interesting part is the tuning, not the raw numbers.
The bigger differentiator is noise control. The JuniorJam Plus uses hybrid active noise cancelling to isolate up to 87% of ambient noise. That matters for a kid on a plane, in a car, or in a busy classroom: less background roar means they can hear their content clearly without cranking the volume up. It's the single most important safety feature here, because if a child can hear what they're playing at a moderate level, they're less tempted to push it louder.
Comfort and fit are aimed at growing kids. The ear cups are leather, on-ear, and circular, with a soft headband and a lightweight, flexible frame that adjusts from little ones up to teens. You get Bluetooth 5.1 with a 30-foot range, fast USB-C charging that fills the battery in about 60 minutes, and up to 22 hours of playback — plenty for a long trip, though not the longest in this comparison. The box includes a storage bag, USB-C and audio cables, and a sharing cable, plus a one-year warranty.
Who should buy it: parents who want the strongest noise-management story, a wired option for backup, and a headset that's genuinely comfortable for long sessions. Who should skip it: if your child needs two full days of battery between charges, or you want the fun LED look, look at the other option.
MEE audio's KidJamz KJ55BT makes its pitch on stamina and personality. The headline number is 40 hours of battery life — nearly double the Puro. For a kid who forgets to charge anything, or a long-haul trip with no outlet in sight, that's a real practical advantage. It also runs Bluetooth 5.4, the newer wireless standard in this matchup, which generally means a more efficient, more stable connection. Range is the same 30 feet.
Safety works differently here. KidJamz uses a built-in limiter that holds sound pressure below 85 dB, same as Puro. But MEE adds a clever twist: a hidden button combination lets parents temporarily disable the limiter for noisy environments like travel. That's a genuinely useful feature — it means the headphones stay usable when the world around them is loud, without permanently raising the safe ceiling. There's also a 3.5 mm jack, so it works wired when the battery runs dry or on a flight with a seat-back screen.
The fun factor is the other half of the story. Multicolor LEDs with eight color patterns light up graphics on each ear cup, and MEE offers optional personalization — a name, graphic, or logo. Four distinct audio modes let kids tweak the sound at the press of a button. Durability is engineered in with fewer moving parts, padded ear cups, and a flexible cushioned headband, sized for ages four and up. The 40 mm dynamic drivers are slightly larger than you'd expect at this price-adjacent tier, and the build uses plastic, silicone, and fabric.
A built-in microphone and on-board controls handle online classes, video chats, gaming, and calls without reaching for a tablet. It ships in rigid packaging with a protective case and a one-year warranty.
Who should buy it: families who want maximum battery, a wired fallback, the newest Bluetooth, and a design kids will be excited about. Who should skip it: if your child is easily distracted by lights, or you specifically want active noise cancelling, this isn't the pick.
• Best for noise management → Puro Sound Labs. Hybrid active noise cancelling with up to 87% ambient isolation is the standout feature here.
• Best for battery life → MEE audio KidJamz KJ55BT. Up to 40 hours versus 22 hours is a clear win for the MEE.
• Best for fast charging → Puro Sound Labs. A roughly 60-minute USB-C charge is a big deal when you're packing in a hurry.
• Best for connectivity → MEE audio KidJamz KJ55BT. Bluetooth 5.4 is newer than the Puro's 5.1.
• Best for wired backup → MEE audio KidJamz KJ55BT. The 3.5 mm jack means it keeps working when the battery doesn't (the Puro also includes an audio cable, so both have a wired path — the MEE's dedicated jack is the more convenient one).
• Best for fun factor → MEE audio KidJamz KJ55BT. Eight LED color patterns and optional personalization make it the more exciting pair for a kid.
• Best for long listening comfort → Puro Sound Labs. Leather on-ear cups and a lightweight adjustable frame are built for extended sessions.
• Best for travel with loud background noise → Puro Sound Labs, unless you plan to use the MEE's parent-disabled limiter in travel mode, in which case the MEE closes the gap.
In my opinion, the Puro Sound Labs JuniorJam Plus is the better pick for most families. Active noise cancelling plus up to 87% ambient isolation does more for a child's real-world listening than a bigger battery does, and the 85 dB limiter is always on rather than something a parent has to remember to switch back. That said, if your kid constantly runs batteries flat or you want the LED look and newest Bluetooth, I'd recommend the MEE audio KidJamz KJ55BT without hesitation. Check the current price on Amazon before you decide — both sit in the same general category, and the value math shifts with whatever deal is live.
FAQ
how do wireless bluetooth headphones work
A Bluetooth headphone has a small radio chip that pairs with your phone or tablet and receives a digital audio stream over the air, usually within about 30 feet. The headphones then convert that digital signal into sound through their drivers — in these two cases, dynamic drivers with a 20 Hz–20 kHz range.
Most wireless headphones enter pairing mode automatically the first time you power them on, or when you hold the power button for a few seconds until the indicator flashes. Once the light blinks, the headset shows up in your device's Bluetooth menu. Both the Puro and the MEE KidJamz use standard Bluetooth pairing, so the same steps apply.
how connect bluetooth headphones to phone
Open your phone's Bluetooth settings, make sure Bluetooth is on, and select the headphone name from the list of available devices. Confirm the pairing prompt if one appears, and the audio routes through the headphones. If the name doesn't show, put the headphones back into pairing mode and try again.
how to connect sony wh ch520 on ear wireless bluetooth headphones
That model pairs the same way as any Bluetooth on-ear headphone: power it on, hold the power button until the pairing light flashes, then pick it from your phone's Bluetooth list. The process is essentially identical to pairing the Puro Sound Labs or MEE audio KidJamz KJ55BT — the brand changes, the steps don't.
