• Stellar Labs Inline Volume Control — biggest strength: it puts volume control back in your hand on any wired 3.5mm headphone that doesn't have one, and it's genuinely useful on high-output sources like in-flight entertainment systems.
• Stellar Labs Inline Volume Control — biggest trade-off: it's an accessory, not headphones. No drivers, no cushions, nothing to listen through on its own. "In Ear" and "Supra-Auricular" in the listing refer to what it's intended to pair with, not what ships in the box.
• Acer Kids Headphones — biggest strength: a 74/85dB adjustable volume limiter, an adjustable headband sized for ages 3–12, and a foldable build with reinforced hinges and a tangle-free cable.
• Acer Kids Headphones — biggest trade-off: no microphone, and the volume ceiling is deliberately low. That's the point, but it means adults won't want them for music or calls.
• Buy the Stellar Labs adapter if you already own headphones and just need to tame the volume. Buy the Acer Kids Headphones if a child needs their own pair for school, travel or a tablet.
This is a small black inline controller that plugs into your sound source and gives you a 3.5mm jack on the other end for your existing headphones. That's the whole idea, and it's a good one. If your headphones have no local volume control, this adds one. If your source is unusually loud — the manufacturer specifically calls out airline in-flight entertainment systems and audio gear with high output levels — this sits between the two and lets you dial things down without fighting a menu.
The second use case is the interesting one. Low-impedance headphones plugged into a device designed for a higher load can sound harsh and too loud. This adapter gives you a physical dial to correct that mismatch. It's the kind of thing you buy once, toss in a travel pouch, and forget about until the seatback screen blasts you at full volume.
Who should skip it? Anyone who wants actual headphones. There's no driver here, no ear cushion, no cable to your ears — just a controller and a jack. It's also a wired-only, 3.5mm-only solution, and it carries a 1-year warranty. If your phone or tablet dropped the headphone jack, this won't help you. And if your headphones already have a volume wheel or buttons on the cable, you're paying for a feature you already have.
In my opinion, this is a niche accessory that does its niche well. It's for the traveler, the tinkerer, the person with a drawer full of decent headphones that all lack inline control.
The Acer Kids Headphones are a finished product aimed at a very specific buyer: a parent with a child roughly 3 to 12 years old. The 74/85dB adjustable limiter is the headline feature, and it's the one that actually matters. You set the ceiling, the child can't push past it, and their hearing is protected on long flights, in the car, or during a tablet session that runs longer than you planned.
The hardware is built around kids being kids. Reinforced hinges, an "oops-proof" design, and a tangle-free 3.5mm cable that Acer says is bend-tested thousands of times. The headband adjusts as your child grows, and the whole thing folds up small enough to disappear into a backpack. At 8 ounces with memory foam ear cushions, it's light enough that a kid will actually keep it on. The 40mm dynamic drivers and 32-ohm impedance are mainstream, easy-to-drive specs — nothing exotic, just sensible for a Chromebook or tablet.
Two things to know before you buy. First, there's no microphone. Your child can still talk through the mic on the connected device, but not through the headset. Second, that volume ceiling is real. If you're hoping an adult can borrow these for a podcast, the limiter will frustrate you.
The materials are CPC/CPSIA certified non-toxic, which is the kind of detail parents care about and most headphone listings skip. Backed by a 3-year manufacturer warranty. For school, travel, and daily tablet use, it fits the brief.
• Best for hearing protection → Acer Kids Headphones. The 74/85dB adjustable limiter is a hard ceiling you control. The Stellar Labs adapter has no limiter at all — it just reduces volume manually.
• Best for using headphones you already own → Stellar Labs Inline Volume Control. It upgrades existing gear instead of replacing it.
• Best for kids ages 3–12 → Acer Kids Headphones. Adjustable headband, lightweight build, foldable, and drop-resistant.
• Best for fixing a too-loud source → Stellar Labs Inline Volume Control. Built specifically for high-output gear and airline seatback systems.
• Best for long wear comfort → Acer Kids Headphones. Memory foam cushions and an 8-ounce build designed for extended use.
• Best for travel with a child → Acer Kids Headphones. Folding design, tangle-free cable, and a volume cap for the plane.
• Best for adults and general listening → Stellar Labs Inline Volume Control. The Acer set is tuned and capped for children, not grown-ups.
• Best for a gift → Acer Kids Headphones. It's a complete, ready-to-use product rather than an accessory that needs a second purchase.
If I had to pick one, I'd pick the Acer Kids Headphones — but only because most people searching these two products together are shopping for a child. It's a finished, safe, durable product with a volume limiter, a 3-year warranty, and a design that survives real use. The Stellar Labs Inline Volume Control is the smarter buy if you're an adult fixing a specific problem with headphones you already love. Match the product to the person, not the other way around.
how to disable volume control on wired headphones
You can't remove a volume control that's built into a cable, but you can work around it. The Stellar Labs Inline Volume Control does the opposite — it adds a control where none exists. If your headphones already have one, just leave it at maximum and adjust volume on your device instead.
do earbuds have volume control
Some do, many don't. Plenty of wired earbuds ship with no inline control at all, which is exactly the gap the Stellar Labs adapter fills. It accepts any 3.5mm headphone, including earbuds, and gives you a physical dial.
No. Acer states plainly that these headphones do not include a mic. Your child can still speak through the microphone built into the connected tablet, laptop or phone, but not through the headset itself.
The headband is adjustable and Acer sizes it for ages 3 to 12, so it's designed to grow with your child. The foldable build and 3-year manufacturer warranty also suggest it's meant to last through several school years.
