If you want volume control built right into a pair of headphones for a whole group of listeners, choose Bulktech 10; if you need a small inline volume dial that tames the loud output of earbuds or a speaker you already own, choose Cubilux 3.5mm.
Bulktech 10 vs Cubilux 3.5mm at a Glance
• Bulktech 10 — biggest strength: Ten complete on-ear wired headphones, each with its own in-line remote for volume, all with a 3.5mm jack and a 5-foot cord. You get volume control and the headphones in one purchase.
• Bulktech 10 — biggest trade-off: It is a 10-pack, so you commit to ten units whether you need them or not. It is built for sharing, not for a single listener.
• Cubilux 3.5mm — biggest strength: A stepless, analog volume dial on a 4-foot extension cable that lets you fine-tune any 3.5mm device with precision, including turning headphones down just enough for sleeping.
• Who Bulktech 10 is for: Teachers, schools, libraries, clinics, museums, airlines and anyone equipping many people with their own headphones at once.
• Who Cubilux 3.5mm is for: A single listener who already owns good earbuds, headphones or a speaker and wants a physical dial to trim the volume in fine steps.
Bulktech 10 is a set of ten wired on-ear headphones with leather ear cushions, a lightweight adjustable frame and swivel cups that fold flat for stacking and storage. Each pair carries a 3.5mm jack, so it plugs into tablets, phones, PCs, Chromebooks and other smart devices without an adapter. The brand rates the impedance at 32 ohm and the frequency range at 20–100, with a dynamic driver inside. Every set ships with a remote control that handles volume, and the cord runs 5 feet.
The real story here is volume control per listener, at scale. If you are running a classroom, a computer lab, a library listening station, a health center waiting room or a museum audio tour, you want each person to be able to set their own level without you handling a single shared device. The in-line remote on each pair does exactly that. The 5-foot cord gives kids and adults room to sit back from a screen, and the thick wire plus the extra-durable build are aimed squarely at daily handling by children. The swivel cups mean the whole set stacks down when the day is over. Since it is a 10-pack, you also get spares on the shelf, which matters in any shared environment where one pair always goes missing.
Who should buy it: anyone buying headphones for a group, a school, a training room, a travel kit or a family with several kids. Who should skip it: a single adult who just wants one nice pair for commuting. Ten pairs is ten pairs, and there is no microphone and no active noise control, so it is not the pick for calls or for blocking out a plane engine. It is a practical, volume-controllable, share-ready headphone — not a personal audiophile set.
Cubilux 3.5mm is not a headphone at all. It is a 4-foot male-to-female 3.5mm extension cable with a stepless analog volume dial built into the line. You plug your existing earbuds, headphones or speaker into the female end, plug the male end into your device, and you turn a physical wheel to set the level you want. Stepless means there are no fixed clicks — you can dial in a very specific point, which is the whole appeal. The build uses oxygen-free copper wire and gold-plated connectors, and the manufacturer states it maintains original music quality without added loss or static.
Two limits are stated plainly, and they matter. First, this cable does not amplify sound — it will never make anything louder, only quieter. Second, it does not control microphone volume; the mic signal passes through, but the dial only adjusts the audio output. It is also specified as compatible with a headphone amplifier but not with a speaker amplifier, and it is recommended for volume control and muting on personal audio devices. It works with most smartphones that have a 3.5mm jack, though specific phone models are not listed.
Who should buy it: someone whose phone, tablet or laptop jumps from too quiet to too loud in one step, or whose earbuds are simply too hot at the lowest setting. The manufacturer's own example is telling — turning headphones down just enough for sleeping. That is a precision problem, and a stepless dial solves it. Who should skip it: anyone hoping to make quiet headphones louder, anyone wanting to control mic level, and anyone who does not already own a 3.5mm device to plug it into.
Side-by-Side: Which Should You Choose?
• Best for equipping a group → Bulktech 10. Ten pairs, ten volume remotes, one purchase.
• Best for classrooms, libraries, clinics and labs → Bulktech 10. Swivel cups, stackable storage, kid-friendly build.
• Best for one person who needs quiet listening at night → Cubilux 3.5mm. Designed to bring levels down just enough.
• Best for durability under daily handling by children → Bulktech 10. Thick wire and extra-durable materials are part of the design.
• Best for preserving sound quality through the connection → Cubilux 3.5mm. Oxygen-free copper and gold-plated connectors are specified.
• Best if you need more volume → neither, honestly. Cubilux explicitly does not amplify, and Bulktech is a standard 32-ohm on-ear set, not a high-output one.
• Best if you need a microphone for calls → neither. Bulktech has no mic; Cubilux passes mic signal through but cannot adjust mic volume.
In my opinion, most people searching this comparison need one of two very different things, so I would buy based on that split. If I were outfitting a classroom, a lab or a family with several kids, I would buy Bulktech 10 — the combination of ten pairs, per-listener volume remotes and stackable swivel cups is hard to beat for shared use. If I were a single listener whose earbuds or speaker are too loud at the lowest setting, I would buy Cubilux 3.5mm — a stepless dial is the right tool for that job, and it is the only one of the two that gives you precise, granular control. Just remember it reduces volume; it never adds any. Check the current price on Amazon before you decide, since the two solve completely different problems.
how to disable volume control on wired headphones
Volume control on wired headphones is usually a passive in-line dial or a button pod on the cable, and it cannot be "turned off" through software because it is a physical component. The practical workaround is to set the level on the headphones themselves to maximum and then adjust the actual volume from your device. With the Cubilux 3.5mm, the in-line dial is the volume control, so leaving it wide open hands control back to your device.
do earbuds have volume control
Some do and some do not — it depends entirely on the model. Earbuds with an in-line remote or a button pod on the cable can adjust volume; plain earbuds with no controls cannot, and you adjust everything from the device. If your earbuds lack controls, an inline attenuator like the Cubilux 3.5mm adds a physical dial to the cable. Note that the Cubilux dial only lowers volume and cannot raise it.
No. Cubilux states clearly that this volume control does not amplify sound and will not boost volume. It is an attenuator, meaning it can only reduce the audio output signal coming from your device. If your problem is that everything is too quiet, this cable will not fix it — you would need a headphone amplifier instead.
Yes. Every pair in the Bulktech 10 set has a universally compatible 3.5mm jack, so it connects to tablets, phones, PCs, Chromebooks and similar devices, and each pair has its own in-line remote for volume. The cord is 5 feet long. If your phone has no 3.5mm jack, you would need your own adapter, which is not included.
