How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a simple, do-everything wired earbud with an in-line remote for calls, gaming and everyday listening on older phones and tablets, choose BENEWY in-Ear Headphones; if you need a serious all-metal IEM with a detachable cable, a wider frequency range and HiFi-grade tuning for music and monitoring, choose Linsoul KZ ZVX Pro.
• BENEWY in-Ear Headphones — biggest strength: a full three-button in-line remote with mic (volume up/down plus play, pause, track skip, answer and hang up), a 3.5mm gold-plated plug, a 14mm dynamic driver and a 2-year manufacturer warranty — plug-and-play on almost any device with a headphone socket.
• BENEWY in-Ear Headphones — biggest trade-off: it's a fixed-cable design in white, with a 20Hz–20kHz range and 32Ω impedance, so it's aimed at convenience and compatibility rather than audiophile tuning.
• Linsoul KZ ZVX Pro — biggest strength: an all-metal housing, an inner magnetic dynamic driver, a 0.75mm 2-pin detachable OFC cable and a wide 20Hz–40kHz range with 18Ω impedance — a proper IEM built for sound quality and long-term ownership.
• Linsoul KZ ZVX Pro — biggest trade-off: the detachable-cable, enthusiast-style build and 1-year warranty make it a more specialist purchase than a grab-and-go earbud, and it's silver only.
• Who each pick is for: BENEWY for casual listeners, commuters, gamers and anyone with an older iPhone, iPad, Samsung or MP3 player who wants one cheap-feeling-free, low-fuss pair; Linsoul KZ ZVX Pro for music lovers, musicians and tinkerers who care about tuning, build and replaceable cables.
The BENEWY pair is the definition of a practical wired earbud. It uses a 14mm dynamic driver with a 20Hz–20kHz frequency range, 32Ω impedance and 100±3dB sensitivity, and it throws in a three-button in-line controller with a built-in microphone. That controller isn't decorative: the middle button handles play and pause, answers and hangs up calls, rejects a call with a two-second press, skips forward with a triple click and back with a double click, while the [+] and [−] buttons adjust volume. For anyone who takes calls on the move or plays mobile games and wants quick controls, that's a genuinely useful setup.
Build-wise it's a mix of rubber, aluminium, stainless steel and plastic, with a soft, flexible TPE cable that the maker says is treated to resist wear and corrosion, plus a 3.5mm gold-plated plug. It ships with a pair of eartips and a plastic carrying case, and it's covered by a 2-year manufacturer warranty. The in-ear shape is designed to isolate external noise and limit sound leakage, which is exactly what you want on a bus or a noisy office.
Who should buy it? If you own an iPhone SE, 6, 6s, 6 Plus, 6s Plus, 5, 5c or 5s, an iPad Mini or Air, an iPod touch or Nano, a Samsung Galaxy, an HTC, an LG, or pretty much any Android, Windows or MP3 device with a 3.5mm socket, this is a grab-and-go option that works out of the box. Note that newer iPhones from the 7 onward need a 3.5mm adapter, which isn't included.
Who should skip it? If you want replaceable cables, an all-metal shell, or a tuning aimed at critical listening, this isn't that product. It's a comfort-and-convenience earbud, not an audiophile tool.
The KZ ZVX Pro is a different animal entirely. It's an all-metal IEM built from high-density alloy that's shaped, polished and buffed to a glossy finish — silver only — and it feels like a piece of hardware rather than a disposable accessory. Under the hood sits an inner magnetic dynamic driver with a precision magnetic circuit, a larger magnet and a wider-diameter voice coil, and KZ says the magnetic gap has been tightened to just 0.1mm to cut interference and signal loss. Whether or not you buy every marketing claim, the design intent is clear: lower distortion and stronger transient response.
The headline numbers back that up. The frequency range runs 20Hz–40kHz — double the top end of the BENEWY — with 105dB sensitivity and a low 18Ω impedance, which makes it easy to drive from a phone or a portable player. The 0.75mm 2-pin detachable connector is the real selling point for enthusiasts: you can swap or upgrade the OFC cable, which extends the life of the earphones and lets you tune the sound to taste. It also has a microphone, passive noise cancellation from the sealed in-ear fit, and soft silicone tips that are 3D-tested for comfort and stability.
Who should buy it? Musicians, hobbyist listeners and anyone who treats earphones as gear rather than a consumable. If you listen across classical, jazz, pop and rock and want one pair that handles all of it, the tuned acoustic curve is aimed squarely at you. If you like the idea of replacing a worn cable instead of the whole earphone, this is the smarter long-term buy.
Who should skip it? If you just want to plug in and forget it, or you dislike the idea of fiddling with connectors, the detachable-cable design and 1-year warranty may feel like more involvement than you want.
• Best for call and media controls → BENEWY in-Ear Headphones. It has a dedicated three-button remote with volume up/down plus play, pause, track skip and call handling; the KZ ZVX Pro has a remote and mic but a simpler control set.
• Best for sound quality and detail → Linsoul KZ ZVX Pro. A 20Hz–40kHz range, an inner magnetic dynamic driver and a 0.1mm magnetic gap point to a more refined, lower-distortion tuning than the BENEWY's 20Hz–20kHz driver.
• Best for build and long-term ownership → Linsoul KZ ZVX Pro. All-metal housing plus a 0.75mm 2-pin detachable OFC cable means you can replace the cable rather than the earphones.
• Best for easy plug-and-play compatibility → BENEWY in-Ear Headphones. It lists broad support for older iPhones, iPads, iPods, Samsung, HTC, LG, Android, Windows and MP3 devices with a 3.5mm jack.
• Best for driving from a phone → Linsoul KZ ZVX Pro. Its 18Ω impedance is easier to drive than the BENEWY's 32Ω, so it should reach volume more readily on modest sources.
• Best for noise isolation on a budget-minded setup → BENEWY in-Ear Headphones. It's explicitly designed to isolate external noise and minimise leakage, with a soft TPE cable built for daily wear.
• Best warranty coverage → BENEWY in-Ear Headphones. It carries a 2-year manufacturer warranty versus 1 year for the KZ ZVX Pro.
• Best for tinkerers and musicians → Linsoul KZ ZVX Pro. The detachable cable, all-metal shell and HiFi-oriented tuning are made for people who swap, upgrade and listen critically.
• If price matters most: check the current price on Amazon for both before deciding — the page has a button for each, and the value call depends on what you're paying on the day.
My Verdict
On paper, yes. The KZ ZVX Pro reaches 40kHz versus 20kHz, uses an inner magnetic dynamic driver with a tightened 0.1mm magnetic gap, and has an all-metal housing. The BENEWY is a solid everyday 14mm dynamic driver earbud, but it isn't tuned as an audiophile IEM.
Only for newer iPhones. It covers iPhone SE, 6, 6s, 6 Plus, 6s Plus, 5, 5c and 5s directly, but the maker states you'll need a 3.5mm adapter for iPhone 7, 7 Plus, 8, 8 Plus and X. Android, Windows, iPad, iPod and MP3 devices with a headphone socket work as-is.
The Linsoul KZ ZVX Pro. Its 0.75mm 2-pin connector lets you detach and replace or upgrade the OFC cable, which extends the earphones' lifespan. The BENEWY uses a fixed TPE cable, which is flexible and wear-resistant but not replaceable.
The Linsoul KZ ZVX Pro, thanks to its 18Ω impedance versus the BENEWY's 32Ω. Lower impedance generally means a phone can push it to a higher volume with less effort, though both are wired 3.5mm designs.
