How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired, over-ear headphone with a big 30mm driver and a wide 10Hz–25kHz frequency range, choose Panasonic RPHX35K; if you need a slim true-wireless in-ear set with a charging case and ENC call noise cancelling, choose Fabater Lightweight Headphone Noise.
• Panasonic RPHX35K — biggest strength: a 30mm dynamic driver paired with a neodymium magnet and a 10Hz–25kHz frequency response, which points to a fuller, more extended sound than a tiny earbud driver can typically produce.
• Panasonic RPHX35K — biggest trade-off: it's a wired design in a plastic housing, so you're tethered to your device and there's no charging case, no onboard battery and no active noise cancelling — just sound isolation.
• Fabater Lightweight Headphone Noise — biggest strength: genuine portability. Two in-ear buds, a 600mAh charging case, 45mAh per bud, a slim 8mm-wide / 6mm-thick profile and ENC noise cancelling for calls.
• Fabater Lightweight Headphone Noise — biggest trade-off: in-ear buds with small drivers can't match the driver size or frequency range of a 30mm over-ear unit, and the spec sheet gives no frequency response figure at all.
• Pick the Panasonic if you listen at a desk, on a couch or anywhere you don't mind a cable and you care most about driver size and sound range.
• Pick the Fabater if you're commuting, studying or taking calls and you want something that disappears in your pocket.
The Panasonic RPHX35K is built around one clear idea: put a real driver on your ears. That 30mm dynamic driver is the headline number here, and it's a meaningful one. Most earbud drivers are a fraction of that size, and driver surface area is one of the physical reasons full-size headphones tend to sound bigger and less strained. Panasonic pairs it with a neodymium rare-earth magnet, which is the standard choice when a manufacturer wants strong magnetic force from a compact magnet assembly. The claimed frequency response runs from 10Hz at the bottom to 25kHz at the top — a genuinely wide spread that covers the deep end of bass and well past the range of human hearing.
Around that driver sits a lightweight, comfortable design in a black plastic enclosure, weighing in at 4.64 ounces. That's light enough that a long listening session at a desk shouldn't feel like a workout for your neck. The noise control approach is sound isolation rather than active cancellation, which makes sense for an over-ear design — the cups themselves do the blocking. There's a cable, so no charging, no pairing, no battery to think about. Plug in and go.
Who should buy it: someone who listens in one place — a desk, a dorm room, a home office — and wants the biggest driver and widest frequency range they can get in a light, simple package. Also a good fit for a teenager, since the listed age range targets teens and the wired design means nothing to lose or recharge.
Who should skip it: anyone who needs wireless freedom, active noise cancelling for a loud commute, or a built-in mic for calls. If you're on a train or a plane and want the world quieted electronically, this isn't that product. And if you want to move around while listening, the cable will annoy you within a day.
The Fabater Lightweight Headphone Noise takes the opposite approach. Instead of one big driver on your head, you get two small in-ear buds that sit inside your ear canal — "sound injected directly into your ears," as the spec sheet puts it, which is a fair description of how in-ear designs deliver audio privately and securely. The buds are remarkably thin: 8mm wide and 6mm thick. That's the kind of profile that lets them sit flush and avoid the pressure points that make chunkier earbuds ache after an hour or two.
The battery story is the other half of the pitch. Each bud carries a 45mAh battery, and the charging case holds 600mAh — a case that size relative to the buds means the case is doing the heavy lifting, topping the buds up between sessions so you're not hunting for a wall outlet mid-afternoon. Charging time is listed at one hour. Connectivity is wireless 5.4, which is the current generation of Bluetooth and brings the stability and power efficiency you'd expect from it.
Then there's the ENC noise cancelling. Note what this is and isn't: ENC (environmental noise cancellation) is aimed at your voice on calls, filtering background noise so the person on the other end hears you clearly rather than a wall of café or street sound. It is not the same as active noise cancellation that quiets the world for you. The product name says "noise concealing," and the isolation you get comes from the in-ear seal plus that call-side processing. The housing is PC and ABS plastic in a nude color, and the package includes the two earphones, the charging case, a charging cable and a manual.
Who should buy it: commuters, students and anyone on calls during the day. The slim fit plus the case makes it a genuinely pocketable setup, and ENC matters if you take meetings from noisy places.
Who should skip it: anyone who prioritizes raw driver size and frequency range, wants a wired connection with zero charging, or prefers the feel of an over-ear cup to something inserted in the ear canal.
• Best for sound-range specs → Panasonic RPHX35K. A 10Hz–25kHz response is a concrete, published figure; the Fabater sheet lists none.
• Best for driver size → Panasonic RPHX35K. 30mm dynamic driver versus small in-ear drivers.
• Best for portability → Fabater Lightweight Headphone Noise. 8mm wide, 6mm thick, in a charging case.
• Best for calls and clear voice pickup → Fabater Lightweight Headphone Noise. ENC noise cancelling is designed for exactly that.
• Best for zero-maintenance listening → Panasonic RPHX35K. Wired means no battery, no charging, no pairing.
• Best for long sessions away from a plug → Fabater Lightweight Headphone Noise. 45mAh per bud plus a 600mAh case and a one-hour charge time.
• Best for teens and desk use → Panasonic RPHX35K. Light 4.64-ounce build, teen age range, simple wired setup.
• Best for commuting and study → Fabater Lightweight Headphone Noise. Slim, private, wireless 5.4, built for exactly those scenarios.
One thing worth being clear about: both list a 90-day warranty, and neither sheet gives me a frequency response, driver size or impedance figure for the Fabater, or any battery figure for the Panasonic — because the Panasonic doesn't have one. What you're really choosing between is a cable and a charging case.
In my opinion, the Panasonic RPHX35K is the better pick if sound hardware is what you're buying for. A 30mm driver, a neodymium magnet and a 10Hz–25kHz range are the kind of published specs that tell you where the engineering budget went, and the 4.64-ounce build keeps it comfortable for long desk sessions. I'd recommend the Fabater Lightweight Headphone Noise instead if your day involves movement, calls and pockets — the slim 8mm/6mm buds, the 600mAh case and ENC for voice are built for that life, and no amount of driver size fixes a cable you don't want. Buy the Panasonic for the sound, the Fabater for the freedom. Check the current price on Amazon before you commit, since that's the one variable I can't weigh in for you.
No. It's listed as a wired headphone with a cable. The spec sheet also lists Bluetooth under wireless technology, but the built-in media field says cable and the design is wired, so treat it as a plug-in headphone.
It has ENC noise cancelling, which targets background noise on your voice during calls. It's not the same as active noise cancellation that reduces surrounding sound for the listener — the in-ear seal is what blocks outside noise for you.
Neither sheet mentions water resistance or sweat protection, so I wouldn't assume either is built for heavy sweating. Between the two, the Fabater's slim in-ear fit and wireless design are more practical for movement, while the Panasonic's cable makes it awkward to move around.
The sheet gives battery capacity, not runtime: 45mAh in each earphone and 600mAh in the charging case, with a one-hour charging time. The case recharges the buds between sessions, which is where most of the extra playtime comes from.
