If you want a pocketable, bass-forward in-ear pair tuned for a tight, sealed fit, choose エレコム(ELECOM) EHP-GB100ARD; if you need a lightweight over-ear set for long listening sessions with a roomier, more relaxed feel, choose Generic FLYSONIC Lightweight Over.
• エレコム(ELECOM) EHP-GB100ARD — biggest strength: A 10 mm external-magnet dynamic driver with a semi-open ducted housing and an aluminum rear housing, all aimed squarely at deep, crisp bass in a tiny in-ear shell.
• エレコム(ELECOM) EHP-GB100ARD — biggest trade-off: It's an in-ear canal design, so the sound depends heavily on getting a good seal from the ear caps, and the 1.2 m Y-type cord is fairly standard in length.
• Generic FLYSONIC Lightweight Over — biggest strength: An over-ear, padded design built around comfort for extended wear, with a long tangle-free cord and universal 3.5 mm compatibility.
• Generic FLYSONIC Lightweight Over — biggest trade-off: Over-ear headphones are inherently bulkier than in-ears, and the 48 Ω impedance is higher, which can matter on weaker sources.
• Buy the ELECOM if: you want compact, bass-tuned in-ear listening on the move.
• Buy the FLYSONIC if: you want comfortable over-ear wear for long sessions at a desk or on the couch.
The EHP-GB100ARD is, first and foremost, an exercise in bass engineering. ELECOM built it around a 10 mm "Torus" external-magnet dynamic driver, paired with large neodymium magnets in an external magnetic circuit. That combination is what the spec sheet credits for the dynamic, sharp low end. The diaphragm is a WFC paper and PU composite chosen for high internal loss and elasticity, and the voice coil is a lightweight CCAW type that the design notes say improves vibration response for a wider range and clearer overall sound. In plain terms: this is a driver package assembled to move air hard down low without smearing the rest.
The housing does real work too. The rear is rigid aluminum, which the specs say reduces unnecessary vibration coming off the driver yoke, so the signal reaching your ear is cleaner and the bass comes across as crisp rather than boomy. The semi-open construction adds ducts at the front and rear of the driver unit, tuned for ventilation resistance so the diaphragm can move more freely. That's a deliberate trade: a freer-moving diaphragm gives you that overwhelming low end, but a semi-open design leaks a bit more sound than a fully sealed one.
So who should buy it? If you're an in-ear listener who prioritizes bass weight and a compact, go-anywhere form factor, this is the obvious pick. The adjustable deep-mount ear caps let you set the insertion depth for a better seal, which is the difference between thin bass and full bass on any canal phone. You also get four cap sizes (XS/S/M/L), a cord keeper, and a pouch — a genuinely useful accessory set for daily carry. The 16 Ω impedance and 95 dB/mW sensitivity suggest it should be easy to drive from a phone or laptop headphone jack.
Who should skip it? If you dislike things in your ear canal, or you want the airy, spacious presentation that only an over-ear cup can give, this isn't the design for you. The 1.2 m Y-type cord is also on the shorter side for desktop use, and with a 6-month warranty it's clearly positioned as a value in-ear rather than a long-haul flagship.
The FLYSONIC Lightweight Over takes the opposite approach: instead of a precision-sealed driver in your ear canal, it puts plush padded earpads around your whole ear. The spec sheet leans on comfort language — lightweight construction for extended wear, cushions that "softly surround the entire ear" — and that's the entire point of an over-ear design. Nothing presses into your canal, so hour after hour of listening at a desk, on a couch, or during a long flight doesn't create that fatigue in-ears can cause.
On audio, FLYSONIC describes clear, immersive sound with an "extra bass" tuning. There's no driver-size or frequency-range figure given, so I'd treat the bass claim as a tuning direction rather than a measured spec — it's a consumer-friendly low-end lift, not a lab-verified curve. The impedance is 48 Ω, which is higher than the ELECOM's 16 Ω. Higher impedance generally means the headphones want a bit more voltage to reach the same loudness, so they'll pair most predictably with a laptop, desktop, or a decent dongle rather than the weakest phone outputs.
The cord is a long, tangle-free one, which is a real quality-of-life difference for over-ear use — you can stretch to the kitchen or lean back from a desk without yanking your device off the table. And because it's a standard 3.5 mm jack, it connects to essentially anything: laptops, desktops, tablets, controllers, older phones, portable players. You get one pair, a 1-year warranty, and a black/gray finish.
Side-by-Side: Which Should You Choose?
• Best for deep bass in a compact form → エレコム(ELECOM) EHP-GB100ARD. The whole design is bass-first: external-magnet driver, composite diaphragm, aluminum rear housing, ducted semi-open shell.
• Best for all-day comfort → Generic FLYSONIC Lightweight Over. Padded over-ear cups and a lightweight build are made for extended wear without canal fatigue.
• Best for portable, on-the-go listening → エレコム(ELECOM) EHP-GB100ARD. An 8 g in-ear with a pouch and cord keeper is built to travel.
• Best for desk and couch sessions → Generic FLYSONIC Lightweight Over. The long tangle-free cord gives you freedom to move while staying plugged in.
• Best for fitting different ears → エレコム(ELECOM) EHP-GB100ARD. Four ear-cap sizes plus adjustable deep-mount positioning let you dial in the seal.
• Best for easy driveability from weak sources → エレコム(ELECOM) EHP-GB100ARD. Its 16 Ω impedance is lower than the FLYSONIC's 48 Ω, so it should reach volume more easily.
• Best for device flexibility → Generic FLYSONIC Lightweight Over. A standard 3.5 mm jack covers laptops, desktops, tablets, and controllers alike.
• Best for longer warranty coverage → Generic FLYSONIC Lightweight Over. It carries a 1-year warranty versus the ELECOM's 6 months.
In my opinion, the smarter buy depends entirely on how you listen. If you want punchy, bass-forward sound in something that lives in your pocket, I'd take the エレコム(ELECOM) EHP-GB100ARD — the driver, housing, and ducting are all engineered with a clear purpose, and the ear-cap selection makes that bass achievable. If comfort for long sessions matters more than portability, I'd go with the Generic FLYSONIC Lightweight Over and its padded over-ear fit and long cord. For most people who want one do-everything pair, I lean toward the ELECOM for its focused design and easy amplification.
By design, yes. The ELECOM is explicitly built around a 10 mm external-magnet bass driver with a composite diaphragm and ducted housing. The FLYSONIC advertises an "extra bass" tuning but gives no driver or frequency figures, so the ELECOM's bass intent is the more concretely specified one.
The FLYSONIC. Its padded over-ear cups sit around the ear instead of inside the canal, which is the whole reason to choose over-ear for extended sessions. The ELECOM is an in-ear canal design, so comfort depends on how well the ear caps fit you.
No. Both are wired 3.5 mm headphones. The ELECOM's lower 16 Ω impedance makes it easier to drive from weaker sources, while the FLYSONIC's 48 Ω pairs best with a laptop, desktop, or decent dongle.
Yes — the two sit in different categories (in-ear versus over-ear), so the current price on Amazon is worth checking for each before you commit. This page provides a button for that.
