How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a lightweight wireless over-ear pair built for kids — 170 g, Bluetooth 5.3, 60 hours of claimed playtime and an 85/94dB volume ceiling — choose JoySpark Kids; if you need a wired, zero-latency over-ear headset with an inline mic and a USB-C adapter for calls, classes and desk work, choose MartiAudio Over-Ear Headphones.
• JoySpark Kids biggest strength: It's the only one of the two that cuts the cord — Bluetooth 5.3, a built-in mic, and a 3.5mm backup jack so listening doesn't stop when the battery does.
• JoySpark Kids biggest trade-off: It's a kids-first product. The 85/94dB limit and touch/button control scheme are designed for young users, not for critical listening.
• MartiAudio biggest strength: Wired plug-and-play reliability with a gold-plated 3.5mm plug plus a USB-C to 3.5mm adapter, so it works with basically anything without charging or pairing.
• MartiAudio biggest trade-off: No Bluetooth at all. There's no battery to run down, but there's also no wireless freedom, and it weighs 7.68 oz (about 218 g) versus JoySpark's 170 g.
• Who JoySpark Kids is for: Parents buying for a toddler, kid or young teen who needs a safe, light, tangle-free headphone for tablets, flights and school.
• Who MartiAudio is for: Adults and older students who want a durable wired headset for calls, online courses, commuting and studio-style listening.
JoySpark Kids is a comfort-first, kid-first wireless headphone, and the specs back that up. The T5 weighs just 170 g, which is genuinely light for an over-ear design, and it pairs memory foam ear cushions with a fully adjustable padded headband. For a small head, that combination is the difference between a headphone a child forgets they're wearing and one they rip off after ten minutes.
The feature set is aimed squarely at parents. There's a 40mm dynamic driver with a 20 Hz–20,000 Hz range and 32 ohm impedance, so sound is full rather than tinny, but the real draw is the 85/94dB volume limit — 85dB for everyday listening, 94dB for noisier places like a plane cabin. Combination-key controls are designed to stop accidental volume changes, which matters when the user is five. Bluetooth 5.3 gives a 10-meter range, and the built-in mic handles calls and homework sessions.
Buy it if: you're buying for a toddler through young teen, you want wireless convenience without a dongle, and ear protection is non-negotiable. Skip it if: you're an adult who wants neutral, uncolored sound or active noise cancellation — that's not what this is built for.
MartiAudio Over-Ear Headphones: Who It's For
MartiAudio takes the opposite approach: no battery, no pairing, no app. The MA569 is a wired over-ear headphone with a gold-plated 3.5mm plug and an included USB-C to 3.5mm female adapter, so it plugs straight into older laptops and modern phones alike without hunting for a dongle. For anyone who has ever watched a Bluetooth pair fail right before a meeting, that's the whole pitch.
Around the ears you get protein leather cushions and a fully adjustable padded headband, and the around-ear seal provides passive sound isolation rather than active cancellation. The build is where the design language gets interesting: reinforced metallic joints, a heavy-duty braided cable, and a matte black finish with 40mm dynamic drivers, 40 ohm impedance, 94dB sensitivity and the same 20 Hz–20,000 Hz frequency range as the JoySpark.
The inline mic and +/- volume control on that braided cable turn it into a work headset as much as a music headphone — hands-free calls, remote work, online courses. Because it's wired, latency is effectively zero, which matters for gaming, video editing or anything where audio and picture need to stay glued together. It weighs 7.68 oz, so it's noticeably heavier than the JoySpark, though the padding is designed to spread that weight. The age range is listed as adult, and it carries a 2-year manufacturer warranty.
Buy it if: you want a dependable wired headset for calls, commuting, classes or desk work, and you like the idea of never charging anything. Skip it if: you need wireless freedom, a volume-limited mode for a child, or the absolute lightest pair you can find.
• Best for young kids → JoySpark Kids. The 85/94dB limit and 170 g weight are the two specs that matter most for small ears.
• Best for wireless freedom → JoySpark Kids. Bluetooth 5.3 with a 10-meter range versus no wireless option at all on the MartiAudio.
• Best for battery life → JoySpark Kids. Up to 60 hours claimed, 40 hours average per the spec sheet, with a 2.5-hour charge — and a 3.5mm jack as backup.
• Best for calls and remote work → MartiAudio. The braided cable's inline mic and inline volume control beat digging a phone out of a pocket.
• Best for zero-latency audio → MartiAudio. Wired means no pairing delay, which suits gaming, video editing and live monitoring.
• Best for plug-and-play across devices → MartiAudio. Gold-plated 3.5mm plus the included USB-C adapter covers phones, tablets, laptops and PCs.
• Best for the lightest possible fit → JoySpark Kids. 170 g is meaningfully lighter than 7.68 oz.
• Best for durability under adult use → MartiAudio. Reinforced metallic joints and a heavy-duty braided cable, backed by a 2-year warranty.
If the buyer is a child, I'd buy the JoySpark Kids without much hesitation. The volume limit, the 170 g weight and the wireless-plus-backup-jack combo are exactly what a parent should be optimizing for, and 60 hours of claimed playtime means it won't be dead on the flight home.
If the buyer is an adult who just wants a reliable wired headset for calls, classes and commuting, I'd buy the MartiAudio. No charging, no pairing, no latency, and a mic on the cable where your hand already is.
They're not really competitors — they solve different problems. Match the headphone to the person and you'll be happy either way. Before you decide, check the current price on Amazon for both, since that's the one variable that can tip a close call.
what are the lightest over ear headphones
By the numbers on these two data sheets, the JoySpark Kids T5 is the lighter option at 170 g, versus 7.68 oz (roughly 218 g) for the MartiAudio MA569. "Lightest" overall depends on the whole market, but between these two the JoySpark is clearly the featherweight.
No. The MartiAudio is a wired headphone with a 3.5mm plug and a USB-C adapter, so there's no battery and nothing to charge. It draws its audio signal from whatever device it's plugged into, which is why it can run indefinitely without a recharge.
Yes. Alongside Bluetooth 5.3, the JoySpark Kids has a 3.5mm jack and ships with an audio cable, so you can run it wired when the battery is low or when you'd rather not pair at all. That dual mode is one of its most practical features.
Both have microphones, but they suit different situations. The MartiAudio puts a high-definition inline mic and volume controls on its braided cable, which is convenient for desk work and long calls. The JoySpark has a built-in mic with one-button call answer and end, which is simpler for a child to use.
