If you want a wired USB-C pair built for low-latency video, gaming and calls with no charging to think about, choose JVC Gumy Connect USB-C; if you need a kid-friendly wireless pair with a volume-reduced, safe-listening design and a long rechargeable battery, choose eKids Trolls Band Together.
• JVC Gumy Connect USB-C — biggest strength: A USB-C plug with a built-in DAC, delay-free audio and an IPX4 splash-resistant rating, so it works for gaming, video and online meetings without an adapter or a battery.
• JVC Gumy Connect USB-C — biggest trade-off: It's a wired in-ear that relies on USB-C, so it won't connect to older 3.5 mm devices and it's aimed at adult use.
• eKids Trolls Band Together — biggest strength: Bluetooth freedom with up to 37 hours of continuous play, a volume-reduced design for kids, a built-in microphone and a bonus detachable audio cable for wired use.
• eKids Trolls Band Together — biggest trade-off: The audio specs are modest (Bluetooth 4, 20 Hz–20 kHz, 32 ohm) and its plastic over-ear build is aimed at kids rather than critical listening.
• Who each pick is for: Choose the JVC for a teenager or adult who wants plug-and-play USB-C audio with no lag; choose the eKids for a child who wants a fun, safe-volume wireless pair for school, home or travel.
The JVC Gumy Connect USB-C is a wired in-ear headphone whose whole identity revolves around that USB-C connector. There's no battery, no pairing, no charging cable to lose — you plug it into a USB-C port and it works. For anyone who's been annoyed by dongles and adapters on modern phones, tablets and laptops, that alone is a meaningful convenience. The built-in DAC is the piece that does the heavy lifting here: JVC states it reduces noise and improves sound quality, which is why the brand positions these for calls and music in high quality over a digital USB-C connection.
Sound is handled by a 9.2 mm dynamic driver with a neodymium magnet and a 16 ohm impedance, with a frequency response up to 22,000 Hz. JVC's headline claim is "delay-free" audio — the pitch being that you can watch a movie or play a game on a phone or PC without the lip-sync lag that wireless headphones sometimes introduce. That's the exact scenario where a wired USB-C set makes sense: competitive gaming, video editing, live streaming, or a Zoom/Teams class where you don't want audio drifting out of sync.
On the practical side, the JVC is rated IPX4, meaning resistance to water splashing from any direction — sweat and light rain are part of the design brief, not an afterthought. The inline remote gives you three buttons (volume up, volume down, and a multi-use audio/phone control) plus a dedicated slide switch for mic on/off. That mic switch is a small but genuinely useful detail for anyone who takes calls and wants to mute instantly without touching their phone. JVC also includes four sets of eartips in XS, S, M and L, so you can dial in a secure, isolating fit, and the package includes the eartips, the headphones and a user manual, backed by a one-year parts and labor warranty.
Who should buy it? If you're an adult or older student who lives in USB-C — a recent phone, a laptop, a tablet — and you want low-latency audio for gaming, video and meetings, this is a clean fit. I'd recommend it for anyone who'd rather not manage a battery. Who should skip it? If your devices still use a 3.5 mm jack, or if you're shopping for a young child, this isn't the right tool — it's an in-ear built for adult use with a USB-C-first design.
The eKids Trolls Band Together headphones are built for a completely different owner: a kid. The design language is unmistakable — graphics inspired by the Trolls Band Together movie, a pink plastic over-ear frame, padded ear cushions and an adjustable headband that grows with a child's head. eKids describes itself as a maker of interactive electronics for kids, and this product fits that mold: it's less about audiophile specs and more about being fun, durable and safe for young listeners.
The most important feature for parents is that the audio is volume reduced for a safe listening experience on any device. That's the whole point of a kids' headphone, and eKids leads with it. The second headline feature is battery life: a rechargeable battery that provides up to 37 hours of continuous play, with a charge time of around 36 hours. For a child using these for school, a long car trip or a flight, that's a genuinely long window between charges.
Connectivity is flexible in a way kids' gear often isn't. It's a Bluetooth 4 headphone with a 10-meter range, so it pairs wirelessly with a phone, tablet or laptop, and it includes a bonus detachable audio cable so you can switch to wired 3.5 mm mode when you want to — handy on a plane or when the battery is low. There's a built-in microphone for virtual learning, gaming or video calls, and media controls on the earcups via push buttons. It's lightweight, foldable and designed to travel. The audio itself is a 32 ohm dynamic driver with a 20 Hz–20,000 Hz range — perfectly reasonable for streaming music, videos and games, but not built for critical listening.
Who should buy it? A parent shopping for a child who wants a fun, safe-volume, wireless pair for school, home or travel, and who values that long battery life and the foldable, packable design. In my opinion, it's the right pick when the listener is a kid and safety plus convenience matter more than raw fidelity. Who should skip it? Anyone shopping for themselves, for serious gaming latency, or for a wired USB-C connection — this is a Bluetooth-first kids' product, and the design intent makes that clear.

If I were buying for myself, I'd take the JVC Gumy Connect USB-C. In my opinion, the built-in DAC, delay-free audio and IPX4 rating make it the more useful everyday tool for gaming, video and calls on USB-C devices — and never having to charge it is a quiet luxury. But that's a personal pick, not a universal one. If the listener is a child, the eKids Trolls Band Together is the smarter choice: volume-reduced for safety, wireless with a long battery, and foldable for travel. Match the headphone to the person and the use case, and either one does its job well.
Yes — JVC markets it specifically as delay-free for videos and gaming, which is the advantage of a wired USB-C connection with a built-in DAC. That makes it a strong fit for phone or PC gaming where sync matters.
eKids rates it at up to 37 hours of continuous play, with a charge time of roughly 36 hours. If the battery runs out, you can switch to the included detachable audio cable for wired listening.
Yes. They're Bluetooth headphones first, but eKids includes a detachable 3.5 mm audio cable so you can switch between wireless and wired modes on compatible devices.
The eKids Trolls Band Together, in my opinion. Its volume-reduced design, kid-sized adjustable fit and lightweight foldable build are aimed squarely at children, whereas the JVC is an adult-oriented USB-C in-ear with no volume limiting. For current pricing on either, check the button on this page.
