For factory workers, headphones for factory workers are best served by Cyber Acoustics ACM-4004: its wired 3.5mm connection and reinforced braided cord keep the setup simple and practical.
Choose EarFun instead if you want wireless listening, active noise cancellation, and multipoint Bluetooth.
• Cyber Acoustics ACM-4004 — best for a straightforward wired setup; pick this if you want an adjustable on-ear fit and a braided cord with a flexible headband.
• Cyber Acoustics Lightweight 3.5mm — best for keeping a spare pair on hand; pick this if you want a two-headphone pack with adjustable headbands and wired 3.5mm connections.
• EarFun Tune Pro Active — best for wireless listening and calls; pick this if you want active noise cancellation, long stated battery life, and connection to two devices at once.
• AKG K371 — best for detailed, wired listening; pick this if you value a closed over-ear design and a stated frequency range of 5 Hz to 40 kHz.
The ACM-4004 is a wired, on-ear headphone with a standard 3.5mm plug, adjustable headband, and leatherette earpads. Its uncomplicated design makes it a sensible starting point for someone who wants to connect directly to a compatible device rather than manage Bluetooth pairing or battery charging. I rank it first because the combination of a familiar wired connection and reinforced cord is a practical fit for routine listening.
The braided TuffCord is intended to be more durable than a simple, unprotected cable, while the headband is designed to tolerate bending and twisting. Those features may matter in a shared or busy workspace where headphones are handled frequently. The cord is six feet long according to the product information, which allows some movement without putting the plug right beside the listener. The 3.5mm connection still means the device needs a compatible jack.
Its on-ear fit is adjustable, and the earpads are leatherette. The listed driver size is 32mm, and the product includes volume control. These details suggest a basic, easy-to-operate option for listening to audio from a compatible phone, computer, or other device. The product description also identifies recycled plastic as part of its construction.

This listing is for a pack of two ACM-4004-style wired headphones. Each uses a 3.5mm plug, adjustable headband, leatherette earpads, and a braided TuffCord. If a household, classroom, or work area needs a spare pair ready, having two headphones in the pack can be more useful than buying a single unit. The specs describe the headphones, not a different model built specifically for industrial use.
The adjustable on-ear design should suit listeners who prefer a simpler fit and a direct wired connection. There is no Bluetooth pairing step in the listed connection method, and no battery requirement is specified. That can make the setup straightforward for compatible devices. As with the single ACM-4004, the plug limits use to devices with a 3.5mm jack or an appropriate connection path.
The central trade-off is that this is still a basic wired headphone, not a wireless work headset or a documented hearing protector. The available listing information does not provide the same detailed audio specifications as the single ACM-4004 sheet, so I would avoid assuming that the two packages differ in sound or construction beyond what is stated. The two-unit format is the distinguishing practical point.
Some shoppers arrive looking for a neckband headphones gift for teens or even clip on earbuds for ps5. This pack is neither a neckband nor a clip-on earbud; it is an over-the-head, on-ear wired design. I’d choose it when two simple 3.5mm headphones are the goal, not when a shopper needs a particular wearable style or a console-specific feature.
The EarFun Tune Pro Active is an over-ear Bluetooth headphone with active noise cancellation, an ambient sound mode, and a five-microphone call system. Compared with the wired Cyber Acoustics models, it offers more ways to manage calls and connect devices. Multipoint lets it maintain connections with two devices at once, which could be convenient for someone switching between a phone and a computer.
The stated battery life is up to 120 hours with ANC off and up to 80 hours with ANC on. Those are manufacturer-stated figures, not a guarantee for every pattern of use. The product also lists a fast-charge feature: a 10-minute charge is described as providing 15 hours of runtime. Bluetooth 5.4 handles wireless connection, and an included 3.5mm cable offers a wired listening option.
Its over-ear cushions use memory foam, and the headband adjusts. The earcups swivel, while the app provides custom EQ according to the product information. ANC and ambient mode give listeners options for changing how much surrounding sound they hear. But noise cancellation is not a substitute for workplace hearing protection. In a factory, blocking sound could also make spoken instructions, alerts, or equipment warnings harder to notice.
This is the pick I’d consider for someone who needs wireless versatility outside a noisy work zone or in a workplace that explicitly allows this kind of listening. It has more features than the wired options, but that means more reliance on charging and Bluetooth. It is also an over-ear headphone rather than a dedicated communication or safety headset, and the specs do not establish that it is suitable for every industrial environment.
The AKG K371 is a closed, wired over-ear headphone aimed at listeners who care about sound detail. It has 50mm transducers, a detachable cable, and a 3.5mm connection, with a 6.5mm adapter listed as included. Its stated frequency range runs from 5 Hz to 40 kHz. That broad specification and the reference-response design make it a more natural fit for focused listening, editing, or audio work than for someone seeking a rugged factory-specific headset.
The closed oval earcups are designed to provide passive insulation, and the over-ear shape surrounds the ears rather than resting directly on them. This may feel preferable to an on-ear style during longer seated listening sessions. The product information also gives a 32-ohm impedance, which is intended to work with professional and consumer devices. Its cable can be detached, so it is not permanently fixed to the earcups.
The main trade-off is that this is a wired studio-style headphone without the wireless features or active noise cancellation found in the EarFun. Its passive isolation should not be mistaken for certified hearing protection, and the supplied details do not say that it is designed for factory safety use. A closed design may reduce some outside sound, but it can also make awareness of nearby activity more difficult.
I’d put the K371 on the shortlist for someone who wants a wired, over-ear option for quiet or controlled listening and values the listed audio specifications. I would not choose it simply because a factory floor is loud. For that situation, the critical question is whether the employer permits headphones and what hearing protection the work actually requires.
How We Picked
We compared the listed connection types, fit, construction details, and audio features for likely everyday uses.
The order reflects my independent editorial opinion about practicality for factory workers, not a claim that any model is workplace-certified.
FAQ
The listed features do not establish that any of these models is certified hearing-protection equipment. Follow workplace safety rules and use the protective equipment specified for the job.
The Cyber Acoustics ACM-4004 and Cyber Acoustics Lightweight 3.5mm use wired 3.5mm connections. Your device still needs a compatible headphone jack.
The EarFun Tune Pro Active supports Bluetooth and multipoint connection, and its five-microphone system is described as supporting clearer calls. It also includes a 3.5mm cable for wired listening.
No. For factory workers, I’d first check workplace rules and required hearing protection before choosing any personal headphones.
