If you want a simple inline volume knob that gives any wired headphone its own local volume control, choose Stellar Labs Inline Volume Control; if you need a complete wired headphone for a kid (or anyone) with a safe volume cap, a built-in mic and a sharing jack, choose awatrue AT2.
• Stellar Labs Inline Volume Control — biggest strength: it isn't a headphone at all, it's a small in-line volume control that plugs into your sound source and adds a 3.5 mm jack for whatever headphones you already own, so any wired pair gains a local volume knob.
• Stellar Labs Inline Volume Control — biggest trade-off: it makes no sound of its own and adds one more short cable segment, so it only helps people who already have headphones they like and a source with awkward volume behavior.
• awatrue AT2 — biggest strength: it's a finished pair of on-ear wired headphones with an 85/94 dB volume limiter, a built-in microphone and a 3.5 mm share jack, so one purchase covers listening, calls and audio sharing.
• awatrue AT2 — biggest trade-off: because the volume is capped for hearing safety, it won't satisfy anyone who wants loud playback, and it's built around kids rather than critical listening.
• Who each is for: the Stellar Labs adapter is for adults fixing a volume problem on existing headphones and audio gear; the awatrue AT2 is for parents buying a safe, school-ready headset for a child.
The Stellar Labs unit is a black plastic in-line controller. It plugs into the 3.5 mm output of your sound source and provides a 3.5 mm jack on the other end for your existing headphones. That's the whole idea. It adds a local volume control to any wired headphone that doesn't have one, and the cable runs in-line, so the control sits between your device and your ears where your hand naturally falls. Connectivity is wired 3.5 mm throughout, and the control method is listed as touch with a volume-control controller. It carries a one-year warranty and weighs roughly 4.54 g, so it's the kind of thing you clip on and forget about.
Where it genuinely earns its place is with gear that has bad volume ergonomics. Think of a source with unusably high output where even the lowest step is too loud, or low-impedance headphones paired with a device designed for a higher load. In-line attenuation between the two fixes that mismatch in seconds, without replacing anything. The description also points at airline in-flight entertainment systems, which is a fair example: you keep your own headphones, and you get a knob instead of hunting for the seat's hidden buttons.
Who should skip it? Anyone who wants headphones, not a fix. It produces no sound on its own, has no microphone, no noise control and no limiter. If you don't already own a wired headphone you like, or your problem is that you need a safe, kid-ready headset, this is the wrong purchase entirely. In my opinion it's a niche tool — but for that niche it's the cleanest answer, because it changes nothing about the headphones you already trust.
awatrue AT2: Who It's For
The rest of the package is built around school life. There's a built-in microphone for online classes, video chats and game voice, and a 3.5 mm jack that works with Chromebooks, tablets, PCs and laptops — the standard school-device list. It also has a built-in 3.5 mm sharing jack, so a second headset plugs straight in and two people hear the same thing without a splitter. The housing is thick PP (ABS is the listed enclosure material), CPC-certified and described as resistant to twisting and bending. Weight is 5.2 ounces, it comes in a BlueGreen colorway, and the warranty runs one year.
Who should buy it? Parents equipping a child for remote classes, homework, car rides and shared screen time. The limiter plus the mic plus the share port is a genuinely useful combination you don't get by adding an adapter to random headphones. Who should skip it? Adults wanting an inline volume knob for their own good headphones, and anyone chasing loud output or serious audio quality. The volume ceiling is the feature, and it's also the limitation. One listing detail worth noting: wireless technology is listed as Bluetooth while connectivity is 3.5 mm wired, so if wireless matters to you, verify that with the product page before buying.
• Best for adding a volume control to headphones you already own → Stellar Labs Inline Volume Control. It's a pass-through adapter; your headphones stay your headphones.
• Best for a complete headset in one purchase → awatrue AT2. Drivers, mic, cable and controls are all included.
• Best for hearing-safe listening for a child → awatrue AT2. The 85/94 dB limiter is the reason it exists.
• Best for taming a too-hot output or a mismatched impedance load → Stellar Labs Inline Volume Control. In-line attenuation between source and headphone is exactly what it's for.
• Best for online classes and video calls → awatrue AT2. The built-in mic is designed for voice communication on Zoom-style platforms.
• Best for sharing audio with a sibling or friend → awatrue AT2. The built-in 3.5 mm share jack removes the need for a splitter.
• Best for airline seatback entertainment → Stellar Labs Inline Volume Control. It gives you a physical volume knob on a system that often hides one.
• Best for travel durability around kids → awatrue AT2. Thick PP construction and a CPC-certified build are aimed at rough handling.
• Best for people who want louder playback → neither. The AT2 is deliberately capped; the Stellar Labs adapter only reduces or trims level, it doesn't add gain.
• Best for weight in a pocket → Stellar Labs Inline Volume Control. At about 4.54 g it's a cable accessory, not a device.
My Verdict
how to disable volume control on wired headphones
Volume control on wired headphones is usually a passive in-line component, not a setting, so there's typically nothing to switch off in software. With the Stellar Labs Inline Volume Control you manage it physically — turn the in-line knob to its maximum and the source's own volume takes over, or remove the adapter from the chain entirely. The awatrue AT2 is different: its limiter is a deliberate safety cap of 85 dB or 94 dB, and it isn't meant to be defeated.
do earbuds have volume control
Some do, some don't — it depends on the model, not the category. Many wired earbuds ship with an in-line control or a remote, while others are bare cable and rely entirely on the source's buttons. That gap is the whole reason the Stellar Labs Inline Volume Control exists: it adds a 3.5 mm in-line volume control to any headphone or earbud that lacks one. The awatrue AT2 takes the opposite approach and builds volume control plus a limiter into the headphone itself.
Yes, per its specs. It uses a universal 3.5 mm jack and is described as compatible with Chromebooks, tablets, PCs and laptops, with a built-in mic for online classes. If the device has a 3.5 mm headphone port, it's designed to plug straight in.
It's an accessory. It's an in-line volume control that plugs into your sound source and provides a 3.5 mm jack for your existing headphones; it has no drivers and makes no sound on its own. The awatrue AT2, by contrast, is a complete headphone with 40 mm drivers, a microphone and a sharing jack.
For a child, I'd go with the awatrue AT2 — the 85/94 dB limiter, built-in mic and share jack are exactly what school and shared listening need. For yourself, if you already own wired headphones you like and just want a volume knob on the cable, I'd take the Stellar Labs Inline Volume Control. Check the current price on Amazon for whichever fits, since that's the one spec neither sheet covers.
