How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want one pair of wireless over-ear headphones that can quiet a noisy commute, last for days between charges, and double as a casual music and call headset, choose RUNOLIM Active Noise Cancelling; if you need a lightweight wired USB headset that keeps your voice clear on endless work calls while filtering out background noise on the mic side, choose Cyber Acoustics AC-104ENC.
• RUNOLIM Active Noise Cancelling — strongest at personal listening: hybrid active noise cancellation, a 100-hour battery spec, Bluetooth 6.0, and a foldable over-ear fit. Biggest trade-off: the ANC only works in Bluetooth mode, not over the 3.5 mm cable.
• Cyber Acoustics AC-104ENC — strongest at voice work: a mono USB headset with dual-mic Environmental Noise Cancellation, an ambidextrous boom arm, and in-line volume/mute controls. Biggest trade-off: it's wired to a USB-A port, so it isn't a portable, wireless listening device.
• Pick RUNOLIM if you want to block out the world and listen — travel, music, movies, casual calls.
• Pick Cyber Acoustics if you want to be heard clearly and control your mic instantly during long desk-based call sessions.
• They are not really substitutes for each other. One is a consumer listening headphone; the other is a workplace communication tool.
The RUNOLIM is built around quiet and endurance. Its headline feature is hybrid active noise cancellation that the brand says cuts external ambient noise, so you can focus in a loud coffee shop or on a busy street. That's the core promise: put them on, flip on ANC, and the environment fades. It pairs over Bluetooth 6.0 with a stated range of about 33 feet (10 meters), and it also accepts a 3.5 mm cable for wired listening — handy on a plane or with a device that has no Bluetooth.
Battery is the other big story. The spec sheet lists a 100-hour average battery life with a 2.5-hour charge time. In my opinion that figure is the single most compelling number on this sheet — it points to a headphone you charge occasionally rather than nightly. For music, the 40 mm dynamic drivers cover a 20 Hz–20 kHz range, and the brand leans into deep bass and clear mids. There's a built-in HD microphone for voice assistants, video calls, and online classes, plus touch controls on the earcups.
Who should buy it: commuters, travelers, students, and anyone who wants one wireless over-ear headphone for music, movies, and occasional calls with very long battery life and real noise cancellation.
Who should skip it: anyone who needs a dedicated, always-plugged-in work headset with a boom mic and instant mute. That's not what this is.
Cyber Acoustics AC-104ENC: Who It's For
The AC-104ENC is a specialist, and it's honest about it. This is a mono USB headset designed for call centers, remote work, and distance learning. Its defining feature is Environmental Noise Cancellation: dual microphones plus an algorithm focus on your voice and reduce background noise, so you sound clear in an open office or a busy home. Note the direction of that noise cancellation — it's about cleaning up what the other person hears, which is the opposite priority from the RUNOLIM's listening-side ANC.
It's wired. You plug it into a USB-A port, and that's a deliberate trade-off: no charging, no pairing, no battery to die mid-meeting. The cable runs 8 feet, which gives you real slack at a desk, and an in-line module puts volume and mic mute (with an LED indicator) right at your fingertips. For someone on back-to-back calls, that mute button matters more than any spec.
Weight is where this headset shines: it's listed at just 0.1 kg (roughly 45 grams), and the brand explicitly frames that as fatigue reduction over long shifts. You get an adjustable headband, a soft leatherette ear pad, and a boom mic that rotates to either side for left- or right-side wear. The brand says it works with major conferencing platforms like Teams, Zoom, and Google Meet. In the box: the headset, the 8 ft cable, a reusable storage bag, and a guide, backed by a 1-year warranty and US-based support.
Who should buy it: call-center agents, remote and hybrid workers, and students who live in video meetings and need clear voice pickup, easy mute, and all-day light comfort.
Who should skip it: anyone who wants wireless freedom, stereo music listening, or noise cancellation for their own ears. This is a single-ear communication tool.
• Best for blocking out noise around you → RUNOLIM Active Noise Cancelling. Its hybrid ANC is aimed at your listening environment.
• Best for making your voice clear to others → Cyber Acoustics AC-104ENC. Dual-mic ENC focuses on your speech.
• Best for battery life → RUNOLIM Active Noise Cancelling. The 100-hour spec and 2.5-hour charge mean very infrequent charging.
• Best for long work shifts → Cyber Acoustics AC-104ENC. At roughly 45 g with an adjustable band and leatherette pad, it's built to disappear on your head.
• Best for travel and music → RUNOLIM Active Noise Cancelling. Foldable over-ear design, 40 mm drivers, Bluetooth 6.0, and a 3.5 mm option for wired listening.
• Best for instant call control → Cyber Acoustics AC-104ENC. The in-line module gives you volume and mute with an LED indicator.
• Best for a no-charge, always-ready desk setup → Cyber Acoustics AC-104ENC. USB-A wired means nothing to pair or recharge.
• Best for a single do-everything headphone → RUNOLIM Active Noise Cancelling, as long as you accept that ANC requires Bluetooth mode.
If I had to pick one for myself, I'd take the RUNOLIM Active Noise Cancelling. It covers far more of my day — music, travel, movies, and casual calls — and the combination of hybrid ANC, a 100-hour battery spec, Bluetooth 6.0, and a foldable over-ear design is simply more versatile. The Cyber Acoustics AC-104ENC is the better tool if your day is calls: it's lighter, wired, and its dual-mic ENC and instant mute are exactly what a call-heavy job needs. So my honest recommendation is to buy the one that matches your primary use — listening versus talking. Check the current price on Amazon before deciding, since that's the one variable that can tip a close call.
Yes for occasional calls — it has a built-in HD microphone and Bluetooth 6.0. But it lacks a boom mic and a one-touch mute, so for constant meetings the Cyber Acoustics AC-104ENC is the more practical choice.
Not the way the RUNOLIM does. Its Environmental Noise Cancellation works on the microphone side, using dual mics to reduce background noise so callers hear you clearly. It's not designed to silence the room for your own ears.
No — the brand states ANC only works in Bluetooth mode, not over the 3.5 mm cable. The wired connection is for listening without ANC, which is worth knowing before you buy.
For call-heavy desk work, the Cyber Acoustics AC-104ENC, at roughly 45 g with an ambidextrous boom and in-line controls. For long listening sessions on the move, the RUNOLIM, thanks to its over-ear cushions and long battery life.
