How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want an inline volume control that plugs into an existing pair of headphones and gives you a real, thumb-friendly volume wheel on the cable, choose Stellar Labs Inline Volume Control; if you need a complete pair of wired earbuds with an inline mic and volume buttons built in, choose APETOO 3.5mm. These two products solve the same annoyance — fiddling with your phone or laptop when you just want the volume lower — from opposite directions. One is an accessory you add to headphones you already own. The other is a full earphone you simply plug in.
• Stellar Labs Inline Volume Control — biggest strength: it adds an inline volume control to any 3.5mm headphone that lacks one, which makes it uniquely useful with airline seat entertainment, older audio gear and high-output sources. Biggest trade-off: it is only a control, so it does nothing for you if you have no headphones to plug into it.
• APETOO 3.5mm — biggest strength: it is a complete, ready-to-use wired earbud set with a TRRS 3.5mm plug, an inline remote with microphone and volume buttons, silicone tips and a storage case. Biggest trade-off: it is a fixed 32 ohm earphone, so you cannot carry it over to a nicer pair of headphones later.
• Choose Stellar Labs if you already own good headphones and just want volume at your fingertips, especially on planes or with gear that runs unusually loud.
• Choose APETOO if you need everything in one purchase — earbuds, cable, mic and controls — for calls, gaming, school or general laptop use.
• In one line: Stellar Labs fixes the headphones you have; APETOO replaces the headphones you have.
The Stellar Labs Inline Volume Control is a small black plastic inline unit that sits on your headphone cable. One end plugs into your sound source — a phone, laptop, in-flight entertainment jack, portable player, anything with a 3.5mm output — and the other end is a 3.5mm jack that accepts your existing headphones. Between the two, the unit provides the volume control your headphones don't have. It is wired, it is passive in the sense that it does not introduce its own wireless technology, and it is a single item, not a pair of earphones. The control method is listed as touch with a volume control controller type, and there is no noise control of any kind.
The real-world case for it is narrower than the case for a whole set of earbuds, but it is a case nothing else fills. If your favorite over-ear headphones are a plain passive pair with no inline remote, and you fly a few times a year, an airline seat jack is exactly the kind of source that can run hot and awkward to adjust. Drop this in the chain and you gain a physical volume control right where your hand already is. The same logic applies to a desktop setup feeding low-impedance headphones from a source designed for a heavier load — the description specifically mentions using low-impedance headphones with devices meant for higher loads. It also suits someone with a vintage receiver or a mixer with an unusually hot output.
Who should skip it: anyone who doesn't already own a 3.5mm headphone they like. This is an accessory, and it only earns its place if there's a headphone at the other end. If your headphones already have an inline remote, you don't need this either. It also won't help if your headphones use a different connector — it is strictly a 3.5mm part. And if you're expecting it to improve sound quality, that's not what it's for; it's a convenience and level-matching tool, not a sonic upgrade. It carries a 1-year warranty and ships in protective packaging, and at 4.54 g it disappears on the cable rather than weighing it down.
The APETOO 3.5mm is the other kind of answer: a complete pair of black wired in-ear earbuds. The plug is a TRRS 3.5mm connector, which is the four-pole type that carries audio plus microphone on a single jack, and APETOO lists broad compatibility across iPhone, Samsung, MacBook Air, MacBook Pro, MacBook, phones, tablets, laptops, desktops, gaming consoles, iPod and MP3/MP4 players with a 3.5mm stereo jack. The inline remote has buttons and a built-in microphone for calls and game chat — note that the microphone sits on the right side — and the control method is button-based on a remote.
The earbuds use dynamic drivers with a 32 ohm impedance and a rated frequency range of 20 Hz to 20,000 Hz. That 32 ohm figure is a normal, easy-to-drive load, which is exactly what you want for plugging straight into a laptop or phone headphone jack without a separate amplifier. The enclosure is ABS plastic, the ear placement is in-ear with a bud shape, and the fit is described as a half-in-ear ergonomic shape with silicone ear tips. That last detail matters: a half-in-ear design doesn't seal off the outside world the way a deep-sealing IEM does, so you stay aware of traffic, announcements and people talking to you. Sound isolation is listed as the noise control approach, and there is no active noise cancellation.
The cable is built from anti-wrap oxygen-free copper, which is meant to survive being stuffed in a backpack or dragged against clothing. You also get a mini storage case and two extra ear tips in the box, plus the earbuds themselves. At 25 g for the set, it's light enough to forget about.
Who should buy it: students, commuters, office workers and anyone whose laptop or console jack needs a cheap, dependable wired earphone with a mic and physical buttons. It's also a sensible pick for kids and school use, since there's no battery to charge and no pairing to lose. The listed age range is teens and adults.
Who should skip it: anyone who already owns a headphone they love and just wants volume control — that person is paying for a whole earphone they don't need. And if you want total isolation from a noisy train or plane cabin, a half-in-ear design deliberately won't give you that. If you need USB-C rather than 3.5mm, look elsewhere, because this is a 3.5mm part despite the storage case listing mentioning a USB-C item.
• Best for keeping your current headphones → Stellar Labs Inline Volume Control. It adds a control without replacing anything.
• Best for a complete, ready-to-go setup → APETOO 3.5mm. Earbuds, cable, mic, buttons and case in one purchase.
• Best for airline in-flight entertainment → Stellar Labs. Taming an unusually loud seat jack is precisely what it's built for.
• Best for calls and game chat → APETOO 3.5mm. It has a built-in microphone and inline buttons; Stellar Labs has neither.
• Best for laptop, MacBook and console use → APETOO 3.5mm. The 32 ohm impedance and TRRS plug are aimed squarely at those jacks.
• Best for awareness of your surroundings → APETOO 3.5mm. The half-in-ear silicone-tip fit is designed not to block everything out.
• Best for travel durability and storage → APETOO 3.5mm. Anti-wrap oxygen-free copper cable, two spare tips and a mini case.
• Best for someone who owns no 3.5mm headphones at all → Stellar Labs makes no sense here; you need the APETOO set.
In my opinion, most people searching this comparison should buy the APETOO 3.5mm, because it's the complete solution: earbuds, mic, volume buttons and a case, all with an easy-to-drive 32 ohm load and a connector that fits laptops, phones and consoles. It's the product that works out of the box for the largest number of buyers. That said, I'd genuinely pick the Stellar Labs Inline Volume Control if I already owned a good pair of passive 3.5mm headphones and my problem was purely that they had no volume control — especially for flying. In that specific situation, no pair of cheap earbuds is a substitute for a control that works with the headphones you actually want to wear. Buy based on whether you're fixing headphones or replacing them.
FAQ
how to disable volume control on wired headphones
do earbuds have volume control
Some do, some don't — it depends on the model. The APETOO 3.5mm earbuds do include an inline remote with volume buttons and a microphone on the right side. Many basic wired earbuds ship with no controls at all, which is exactly the gap the Stellar Labs Inline Volume Control is designed to fill by adding a control to headphones that lack one.
Only with 3.5mm wired headphones. It plugs into a 3.5mm source and provides a 3.5mm jack for your existing headphones, so headphones with a different connector won't work. It's also pointless on headphones that already have their own inline volume control.
APETOO lists compatibility with laptops, desktops, MacBook Air, MacBook Pro, MacBook, phones, tablets, gaming consoles, iPod and MP3/MP4 players that have a 3.5mm stereo jack. The 32 ohm impedance and dynamic drivers are an easy load for those jacks. Just remember the microphone is on the right side, which matters for how you wear them.
