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, comfortable wired earbud with swappable ear tips and a wide frequency range for music listening, choose Panasonic ErgoFit; if you need an in-line microphone and on-cord controls for calls, video meetings and everyday phone use, choose ASKUBSKU 3.5mm.
• Panasonic ErgoFit — biggest strength: Three sizes of ultra-soft earpads (S/M/L), a 9mm neodymium dynamic driver and a stated 12Hz–23kHz frequency range built for music detail.
• Panasonic ErgoFit — biggest trade-off: It's sold as a no-mic model, so you can't take calls or use voice chat with it.
• ASKUBSKU 3.5mm — biggest strength: An in-line remote with a high-sensitivity microphone, plus semi in-ear tips angled 45° to reduce ear pressure and stay put.
• ASKUBSKU 3.5mm — biggest trade-off: Fewer fit options — no multiple tip sizes mentioned — and a narrower stated frequency range of 20Hz–20kHz.
• Choose Panasonic ErgoFit if music comes first and you want to tune the fit to your ears.
• Choose ASKUBSKU 3.5mm if you take calls, sit in meetings, or want pause/play and volume at your fingertips on the cable.
The ErgoFit RP-HJE120-S is, at heart, a listening tool. Panasonic built it around a 9mm neodymium magnet dynamic driver and quotes a frequency response spanning roughly 12Hz to 23kHz, which is a wider claimed range than the ASKUBSKU's 20Hz–20kHz. In plain terms, that spec suggests the ErgoFit is aimed at people who care about hearing the low end of a bassline and the airy top of a cymbal without paying for anything fancy. The 47-ohm impedance and 200mW maximum input power also tell you it's designed to plug into ordinary 3.5mm jacks — laptops, desktops, tablets, MP3 players, older phones — and just work.
The fit story is where Panasonic puts real thought into it. You get three pairs of soft earpads in small, medium and large, and the product notes are refreshingly honest about why that matters: if the tip doesn't match your ear canal, you won't get the sound quality the driver is capable of. That's true of every in-ear bud, but Panasonic is one of the few at this level that hands you the tools to fix it. The buds themselves are a rounded-tip, in-ear plastic-and-rubber design in silver, and the cord is a comfort-length 3.6 feet — short enough to thread through a jacket or bag without tangling into a mess, long enough to reach a pocket.
ASKUBSKU 3.5mm: Who It's For
The ASKUBSKU 3.5mm is a different animal: it's a communication-first earbud. The headline feature is the in-line control pod, which lets you pause and play, nudge the volume up or down, answer or hang up a call, and even trigger your camera shutter without pulling your phone out. If you've ever fumbled for your phone mid-walk, mid-workout or mid-commute, that's the appeal. Pair that with a "newly-upgraded high-sensitivity microphone" tuned for multi-directional pickup and enhanced voice, and you get a bud that's genuinely built for talking as much as listening.
The second thing ASKUBSKU gets right is wearability. The design is a 45-degree semi in-ear shape rather than a deep-canal plug, and the brand specifically calls out "no ear pressure feeling, no pain in ears after long time wear." For people who find traditional in-ear buds uncomfortable after an hour, that semi in-ear approach is the whole point. There's also a magnet on the back of each bud so they clip together around your neck when you're not using them — a small touch that matters if you're constantly taking them in and out at a desk.
On audio, ASKUBSKU claims a dynamic driver with a high-amplitude, low-distortion design "carefully adjusted" for bass detail and clear mid-highs, over a stated 20Hz–20kHz range. That's the standard full-range spec — fine for music, podcasts and calls, but not as wide as the ErgoFit's claimed ceiling. It's a black plastic in-ear with a circular earpiece shape and push-button controls, and the compatibility list is long: Samsung Galaxy S10 down through the A-series, Note 9, Moto, Switch, Kindle, MP3 players, several iPads and more. One practical warning from the brand itself: if the 3.5mm port gets dusty, the buds can act up — clean the jack and reconnect. Who should skip it? Anyone who wants to fine-tune fit with different tip sizes, or who prioritizes the widest possible frequency range over call features.
• Best for calls and meetings → ASKUBSKU 3.5mm. It's the only one of the two with a microphone and an answer/hang-up button.
• Best for music detail → Panasonic ErgoFit. The 9mm neodymium driver and wider 12Hz–23kHz claim point to more low-end extension.
• Best for fit customization → Panasonic ErgoFit. Three tip sizes (S/M/L) let you chase a proper seal.
• Best for long-wear comfort → ASKUBSKU 3.5mm. The semi in-ear, 45-degree design is explicitly built to avoid ear pressure.
• Best for on-cable control → ASKUBSKU 3.5mm. Play/pause, volume and shutter control live on the cord.
• Best for staying put during movement → ASKUBSKU 3.5mm. The angled tips are described as "not easy to fall."
• Best for pure, uncomplicated listening → Panasonic ErgoFit. No mic, no buttons — just plug in and play.
• Best all-rounder for phone use → ASKUBSKU 3.5mm. If you use one pair for everything including calls, its feature set covers more ground.
If I were buying for myself, I'd pick the ASKUBSKU 3.5mm. In my opinion, the in-line controls and microphone make it the more useful everyday bud — you can take a call, pause a podcast and skip a track without touching your phone, and the semi in-ear shape sounds kinder to your ears over a long day. The ErgoFit wins on paper for pure music listening thanks to its wider claimed frequency range and three tip sizes, so if you never take calls and want to tune the fit, that's the smarter pick. But as a single do-everything wired earbud, I'd go ASKUBSKU. Check the current price on Amazon before deciding, since that's the one factor that can tip a close call.
No. The RP-HJE120-S is a no-mic model, so there's no microphone and no in-line remote. If calls matter, the ASKUBSKU 3.5mm is the one with a mic and call controls.
Not necessarily. Panasonic claims a wider 12Hz–23kHz range versus ASKUBSKU's 20Hz–20kHz, which suggests more bass extension. ASKUBSKU counters with a low-distortion driver tuned for clear mids and highs. Which sounds better to you depends on what you listen to.
The ASKUBSKU 3.5mm is designed around comfort, with a 45-degree semi in-ear shape meant to avoid ear pressure. The ErgoFit relies on getting the right tip size — it includes S/M/L pads, so fit it carefully or it won't seal well.
Yes. Both are wired 3.5mm buds and won't work with devices that only support Bluetooth. ASKUBSKU lists broad compatibility with Samsung, Moto, Switch, Kindle, MP3 players and more; Panasonic works with any device that accepts a standard 3.5mm jack.
