If you want a wired, semi-open in-ear tuned around a purpose-built bass driver and a proper seal, choose エレコム(ELECOM) EHP-GB100ARD; if you need a foldable, wireless over-ear with active noise cancelling and a rechargeable battery, choose SXFJF Headphones Deep Heavy.
• エレコム(ELECOM) EHP-GB100ARD — biggest strength: a genuine bass-first acoustic design: a 10 mm external-magnet dynamic driver, neodymium magnets, a WFC paper/PU composite diaphragm, a CCAW voice coil and a rigid aluminum rear housing, all working together for deep, punchy low end.
• エレコム(ELECOM) EHP-GB100ARD — biggest trade-off: it's wired (fixed 1.2 m Y-cord, 3.5 mm L-type plug) and uses passive noise cancellation, so there's no Bluetooth and no battery.
• SXFJF Headphones Deep Heavy — biggest strength: wireless freedom plus convenience: Bluetooth with a microphone for hands-free calls, active noise cancelling with a closed-back design, a rechargeable USB battery, and a foldable over-ear build.
• SXFJF Headphones Deep Heavy — biggest trade-off: it's heavier (240 g) and its bass is delivered through DSP and a "deep bass function" rather than a driver engineered purely for low frequencies.
• Who each pick is for: choose the ELECOM if deep, physical bass from a wired in-ear is your priority; choose the SXFJF if you want wireless over-ear comfort, noise cancelling and all-day cable-free listening.
The EHP-GB100ARD is what happens when a company decides to build an in-ear around one goal: bass. ELECOM calls the platform "Grand Bass," and the spec sheet backs the marketing. The 10 mm outer-magnet dynamic driver uses large neodymium magnets in an external magnetic circuit — a layout chosen specifically to deliver dynamic, sharp low frequencies. Then there's the diaphragm: a WFC paper and PU composite with high internal loss, which is a fancy way of saying it moves freely enough to push real air without ringing. Add a lightweight CCAW voice coil for faster vibration response, and a rigid aluminum rear housing to kill the stray vibrations coming off the driver yoke, and you get a design where every part is pulling toward clean, rich bass.
So who should buy it? Someone who wants deep bass in the most direct way possible: a wired connection from a phone, laptop or portable player, no charging, no pairing, no latency. The 16Ω impedance and 95 dB/mW sensitivity mean it's easy to drive from almost anything with a headphone jack. It weighs about 8 g, so it disappears in your ears. You also get a cord keeper and a pouch, so it's genuinely pocketable.
Who should skip it? Anyone who has moved past wired audio. There's no Bluetooth here, and the noise control is passive only — it works by sealing your ear canal, nothing more. If you take calls on the move or hate cables, this isn't your headphone. And if you want over-ear comfort rather than something inserted in your ear canal, look elsewhere.
SXFJF Headphones Deep Heavy: Who It's For
The SXFJF Headphones Deep Heavy takes the opposite approach: it wraps convenience around the bass. This is a foldable, over-ear wireless headphone in gray, with a closed-back design and ultra-soft ear cushions that the brand describes as ergonomic for long wear. The pitch is simple — put them on, pair once, and forget about cables for the rest of the day.
On the bass front, SXFJF leans on a "deep bass function" that's meant to deliver strong low-end depth alongside HD clarity. It's a software-and-tuning take on bass rather than ELECOM's hardware-first approach, but the frequency response range still covers 20–20,000 Hz, so the full audible spectrum is there. The 32Ω impedance is typical for this class and plays nicely with phones and laptops over Bluetooth.
The real draw is everything around the sound. There's active noise cancelling, and the closed-back cups plus noise-isolation pads help block ambient noise — handy on a noisy street, a busy subway or a flight cabin. There's a built-in microphone for hands-free calls and media controls on the headset. There's a rechargeable battery charged over USB, so you're not buying disposables. And it folds, which matters when you're carrying a 240 g headphone in a bag.
Where does it fit best? Commuting, travel, office work, long listening sessions — anywhere you want isolation and no cable. It's also the obvious pick for anyone whose phone no longer has a headphone jack, since the connection is Bluetooth-first (the spec sheet also lists a 3.5 mm plug, so wired use is possible).
Who should skip it? Anyone who prioritizes maximum bass precision over features. If you want low end shaped by driver physics rather than EQ, the ELECOM is the more honest tool. And if weight bothers you, 240 g on your head is a real consideration over a several-hour session.
• Best for deep, physical bass → エレコム(ELECOM) EHP-GB100ARD — the entire design, from the 10 mm external-magnet driver to the aluminum housing, is built to move air.
• Best for wireless freedom → SXFJF Headphones Deep Heavy — Bluetooth with a microphone and media controls, no cable required.
• Best for noise control → SXFJF Headphones Deep Heavy — active noise cancelling plus a closed-back, isolating design beats the ELECOM's passive seal.
• Best for long listening comfort → SXFJF Headphones Deep Heavy — over-ear with ultra-soft cushions, versus an in-ear that sits inside your canal.
• Best for portability → エレコム(ELECOM) EHP-GB100ARD — at roughly 8 g with a pouch and cord keeper, it vanishes into a pocket.
• Best for travel and commuting → SXFJF Headphones Deep Heavy — rechargeable over USB, foldable, and built to block out engine and street noise.
• Best for zero-latency wired listening → エレコム(ELECOM) EHP-GB100ARD — a straight 3.5 mm connection with no pairing or charging.
• Best if your phone has no headphone jack → SXFJF Headphones Deep Heavy — Bluetooth-first design sidesteps the missing port entirely.
If deep bass is the whole reason you're shopping, I'd take the エレコム(ELECOM) EHP-GB100ARD. In my opinion, a 10 mm external-magnet driver, a composite diaphragm, an aluminum rear housing and a seal you can actually adjust will out-deliver an EQ-based "deep bass function" every time — and the 8 g weight means you'll forget you're wearing them. That said, if you need wireless, noise cancelling and all-day over-ear comfort, the SXFJF Headphones Deep Heavy is the one that fits your life, and I'd recommend it without hesitation for commuting and travel. Match the tool to the job.
what is deep bass in headphones
Deep bass is the low-frequency part of the audio range, roughly the bottom of the 20 Hz–20 kHz band both these headphones cover. In practice it's the rumble you feel from kick drums, bass guitars and sub-bass synths. The ELECOM chases it with driver hardware; the SXFJF chases it with a dedicated deep bass function.

These are two different products, but the general Bluetooth routine is the same: put the headphones in pairing mode, open your phone's Bluetooth settings, and select the device. The SXFJF Headphones Deep Heavy connects the same way — Bluetooth pairing, then media controls on the headset handle playback and calls.

Same principle: turn the headphones on, enable Bluetooth on your source device, and pick them from the list. Note that the ELECOM EHP-GB100ARD isn't wireless at all — it uses a fixed 1.2 m cord with a 3.5 mm L-type plug, so you just plug it in and play.

Bluetooth pairing again — power on, enter pairing mode, select from your device's list. If you're weighing these two, the deciding question is simpler: do you want a wired in-ear tuned purely for bass (ELECOM), or a wireless, noise-cancelling over-ear (SXFJF)?
