How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a featherweight wired pair that stays comfortable for hours of calls and everyday listening, choose Audio Technica ATH-EQ300M; if you need a kid-friendly wireless headset with a built-in mic, huge battery life and volume limits, choose JoySpark Kids. Both lean into the same idea — lightweight headphones that don't weigh you down — but they aim at completely different people. One is a minimal adult ear-fit design; the other is a padded over-ear wireless set built for children. If calls are your priority, that single difference decides almost everything.
• Audio Technica ATH-EQ300M — biggest strength: Extremely light at just 20 g (0.7 oz) with an ultra-thin housing, so it barely registers on your ears during long listening or call sessions.
• Audio Technica ATH-EQ300M — biggest trade-off: It's a wired 3.5 mm design with no built-in microphone listed, so it isn't a true wireless headset for calls.
• JoySpark Kids — biggest strength: Up to 60 hours of playtime, Bluetooth 5.4, Type-C charging and a built-in HD mic make it a genuinely practical wireless headset for kids.
• JoySpark Kids — biggest trade-off: It's over-ear and bulkier by nature, and its 85/94 dB volume limiting and kid-focused tuning are aimed at children, not critical adult listening.
• Who each pick is for: Audio Technica ATH-EQ300M for adults who want the lightest possible on-ear fit for wired listening; JoySpark Kids for parents who want a durable, safe, wireless set for a child.
The ATH-EQ300M is defined by one number: 20 g. That's the entire pitch of this design. The ultra-thin housing and ear-fit shape mean the headphone rests against your ear rather than clamping around it, which is exactly why people reach for lightweight headphones in the first place. The 1.2 m cord gives you enough slack to move around a desk, and the 3.5 mm jack plugs into basically anything with a standard headphone port. With a 20 ohm impedance and a dynamic driver covering 16 Hz to 24,000 Hz, it's an easy load to drive — you don't need a headphone amp to get sound out of it.
In my opinion, this is the pick for someone who wants a barely-there pair for long stretches: working at a desk, listening to podcasts, taking wired calls through a laptop or phone that already handles the mic, or just wanting something that doesn't press on the ears. The rounded earpiece tip and plastic enclosure keep it simple and low-fuss. It also comes in six colors, so if you care about matching your setup, you have options.
Who should skip it? Anyone who wants true wireless freedom, a built-in microphone, or a headset they can walk away from their device with. There's no battery here because there's no Bluetooth audio in the traditional sense — it's a wired listen-first design. If you need a self-contained wireless headset for calls, this isn't it. And if you need one device that a child can safely use unsupervised with volume caps, this isn't the right tool either.
The JoySpark Kids set is built around the opposite priorities: wireless freedom, safety and stamina. Bluetooth 5.4 handles the connection, Type-C fast charging tops it up, and the battery is rated for up to 60 hours of playtime on a single charge. That's the headline. For a kid on a long car ride, a flight, or a week of study sessions, that kind of runtime means you're not hunting for a cable every day. There's also a 3.5 mm jack and wired connectivity as a backup, so it isn't wireless-only.
The safety angle matters too. Volume is switchable between 85 dB and 94 dB, giving a parent a clear ceiling to choose from. The over-ear design uses soft, cushioned ear cups and an adjustable headband, and the ABS construction is meant to survive daily handling by a child. It also includes a built-in HD mic and passive noise cancellation, which makes it workable as a headset for calls — a kid can actually talk to a grandparent or join a class session without a separate mic. The 32 ohm impedance and 20 kHz frequency response are modest, which fits the audience.
Who should buy it? Parents shopping for a durable, comfortable, wireless pair for a child, teen or toddler, especially where battery life and volume limits are the deciding factors. Who should skip it? Adults who want a neutral, detail-focused listening experience, or anyone who wants the absolute lightest possible on-ear fit. Over-ear cushions and a headband simply weigh and bulk more than a 20 g ear-fit design, and the tuning is aimed at younger ears, not critical listening.
• Best for the lightest possible fit → Audio Technica ATH-EQ300M. At 20 g with an ultra-thin housing, it's the definition of lightweight headphones.
• Best for battery life → JoySpark Kids. Up to 60 hours of playtime leaves the wired Audio Technica with nothing to compare.
• Best for wireless freedom → JoySpark Kids. Bluetooth 5.4 with Type-C charging versus a 1.2 m cord.
• Best for safe kid listening → JoySpark Kids. Switchable 85/94 dB volume limiting and kid-focused build.
• Best for a built-in mic and hands-free calls → JoySpark Kids. The HD mic and passive noise cancellation make it the more self-contained headset for calls.
• Best for plug-and-play wired simplicity → Audio Technica ATH-EQ300M. No pairing, no charging, just a 3.5 mm jack.
• Best for critical adult listening → Audio Technica ATH-EQ300M. A 16 Hz–24,000 Hz range and 20 ohm impedance suit straightforward music and podcast listening.
• Best for durability against rough daily use → JoySpark Kids. Cushioned over-ear build and ABS enclosure are designed for children.
For my own use, I'd buy the Audio Technica ATH-EQ300M. The reason is simple: I want headphones I forget I'm wearing, and 20 g with an ultra-thin housing is about as close to invisible as it gets. For wired listening and taking calls through a laptop or phone, it does the job without fuss, and six color options don't hurt. If I were shopping for a child, or I needed a genuinely wireless headset for calls with a built-in mic and serious battery life, I'd pick the JoySpark Kids without hesitation. Match the tool to the person — that's the whole decision.
FAQ
How to wear on ear headphones
How to make on ear headphones more comfortable
Keep sessions reasonable and let your ears breathe between them, since on-ear designs press rather than seal. The ATH-EQ300M's 20 g weight and ultra-thin housing already reduce clamping force, which is the main comfort complaint with heavier on-ear models. If you need cushioning instead of contact, the over-ear JoySpark Kids with soft cushioned cups is the different approach.
How to wear on ear headphones comfortably
Position the earpiece so it covers your ear opening evenly, and avoid pushing it flat against your head. Because the ATH-EQ300M is so light, small adjustments hold well and you shouldn't need to re-seat it often. If comfort is your deciding factor and you prefer padding over a bare fit, choose a cushioned over-ear set instead.
How to clean on ear headphones
Wipe the plastic housing and earpieces of the ATH-EQ300M with a soft, slightly damp cloth, and avoid soaking the driver area or the 3.5 mm jack. For the JoySpark Kids set, gently wipe the ABS shell and cushioned ear cups the same way. Let everything dry fully before use.
