• Sony MDRXB950AP/H — biggest strength: around-ear comfort plus an inline mic and remote for hands-free calling, backed by 40mm dynamic drivers and an Acoustic Bass Booster. Biggest trade-off: it's a full-size over-ear headphone, so it's bulkier and heavier (1.4 lb) to carry than any earbud.
• エレコム(ELECOM) EHP-GB100ARD — biggest strength: a genuinely pocketable in-ear design (about 8 g) built specifically for deep bass, with a semi-open ducted housing and four ear-cap sizes for a tight seal. Biggest trade-off: it's wired-only with no microphone or remote, so it's for listening, not talking.
• Pick the Sony if you want one pair for commuting, calls and long home sessions with an around-ear fit.
• Pick the ELECOM if you want light, low-fuss in-ear bass and don't need a mic.
The MDRXB950AP/H is Sony's take on a bass-first smartphone headset, and the design brief is clear from the spec sheet. It uses 40mm dynamic drivers with a rated frequency range of 3 Hz to 28 kHz, paired with an "Acoustic Bass Booster" that pushes low-end response. That's an unusually wide claimed range at both ends, and it tells you Sony is aiming for a big, full-bodied sound rather than a flat, analytical one.
What really separates it from a plain pair of headphones is the smartphone angle. There's an inline microphone for hands-free calls, and Sony's SmartKey app lets you customize what the inline remote button does — so it works whether you're on an iPhone or an Android phone. The cable is a tangle-free Y-type cord at about 1.2 m, and the earcups swivel so the whole thing folds flatter for a bag. The aluminum enclosure and around-ear design point to something meant to be worn for hours, not just a quick listen.
Who should buy it: anyone who wants a single headset that handles music and phone calls, prefers the feel of an over-ear cup over an in-ear plug, and wants to be able to tweak the remote behavior through an app. Who should skip it: if you want something that disappears into a pocket, or you mainly listen while running or at the gym, this is the wrong shape. It's also worth noting the sheet lists both wired connectivity and Bluetooth 4.0 alongside active noise cancellation — treat those as features to confirm against the listing if they matter to you, since the core pitch here is clearly the wired smartphone headset. As always, check the current price on Amazon before deciding.
The EHP-GB100ARD is a completely different animal: a canal-type in-ear earphone from ELECOM's "GrandBass" line, and every spec on the sheet is aimed at one goal — deep, punchy low end from a tiny driver. The 10mm dynamic driver uses an external-magnet ("outer magnetic") design with large neodymium magnets, and the diaphragm is a WFC paper and PU composite chosen for high internal loss and elasticity. In plain terms, that's a recipe for bass that stays controlled instead of turning to mush.
The rest of the build supports that. A lightweight CCAW voice coil improves how quickly the diaphragm responds, which the sheet ties to a wider range and clearer sound. The rear housing is rigid aluminum to cut unwanted vibration from the driver yoke, and the housing is semi-open with ducts front and rear, tuned for ventilation resistance so the diaphragm moves more freely. The rated range is 20 Hz to 20 kHz at 16Ω impedance and 95 dB/mW sensitivity — easy to drive from a phone. The adjustable ear-caps in XS, S, M and L are there to get a proper seal, which is what actually unlocks the bass in an in-ear.
Who should buy it: listeners who want a light, wired in-ear for bass-heavy music on the train, at a desk or on a walk, and who value the included pouch, cord keeper and spare tips. Who should skip it: anyone who needs a microphone for calls — there isn't one — or who dislikes the plugged, sealed feeling of canal earphones. The sheet doesn't state a mic or remote, so don't expect either.
Side-by-Side: Which Should You Choose?
• Best for bass from a tiny package → エレコム(ELECOM) EHP-GB100ARD: the whole GrandBass design — external magnets, composite diaphragm, ducted semi-open housing — targets low end.
• Best for all-day comfort at home → Sony MDRXB950AP/H: the around-ear aluminum cups are built for long sessions.
• Best for portability → エレコム(ELECOM) EHP-GB100ARD: roughly 8 g per earphone, with a pouch and cord keeper, versus a 1.4 lb over-ear set.
• Best for a secure fit you can tune → エレコム(ELECOM) EHP-GB100ARD: four ear-cap sizes and adjustable mounting depth let you dial in the seal.
• Best for the widest claimed frequency range → Sony MDRXB950AP/H: rated 3 Hz–28 kHz against the ELECOM's 20 Hz–20 kHz.
• Best for plug-and-play on any phone → either: both are wired 3.5 mm, and both are easy to drive.
• Best if you want built-in noise cancellation → Sony MDRXB950AP/H: its sheet lists active noise cancellation, while the ELECOM relies on passive isolation from the seal.
In my opinion, the Sony MDRXB950AP/H is the one I'd buy for most people, because it does more jobs at once — big around-ear bass, a mic for calls, an app-tunable remote and a swivel fold — and it's the more flexible daily driver.
I'd only steer you to the エレコム(ELECOM) EHP-GB100ARD if you specifically want light, wired in-ear bass and never take calls on your headphones. It's the more specialized tool, and if that's your use case, it fits it well. Check the current price on Amazon for both before you commit, since that's the one number that can tip a close call.
FAQ
Yes. The Sony has an inline microphone and a SmartKey-app-configurable remote for hands-free calling. The ELECOM sheet lists no microphone, so it's a listening-only earphone.
Both are explicitly bass-focused — Sony via its Acoustic Bass Booster and 40mm drivers, ELECOM via its GrandBass external-magnet driver and ducted housing. The Sony's over-ear cups move more air; the ELECOM gets its bass from a tight in-ear seal, which depends on picking the right ear-cap size.
No. Both are wired 3.5 mm headphones designed for phones. The ELECOM's 16Ω impedance and 95 dB/mW sensitivity make it especially easy to drive from a handset.
The ELECOM EHP-GB100ARD, in my opinion. It's around 8 g, seals in your ear and comes with multiple ear-cap sizes, so it stays put. The Sony's around-ear, 1.4 lb design is better suited to sitting, commuting or working at a desk.
