If you want a wired in-ear that leans on decades of Sony tuning know-how, a flat tangle-resistant cord and a familiar 3.5mm plug, choose Sony Deep Bass Earphones; if you need dual-driver bass, a metal housing and a mic built to fight background noise on calls, choose jechan Dynamic Balanced Deep. Both are wired, both sit in your ear canal, and both are aimed at people who want more low-end thump than a cheap pack-in pair gives them. The difference is what "deep bass" actually means to each brand.
• Sony's biggest strength: a 9mm neodymium dynamic driver, a 5 Hz–24 kHz claimed frequency range and a Y-type flat cord that resists tangling — plus the reassurance of a name most people already know.
• Sony's biggest trade-off: no noise cancelling at all (noise control is listed as "None"), a plastic housing, and a 3.5mm jack that newer phones without a headphone socket can't use without an adapter.
• jechan's biggest strength: a dual-driver setup with a balanced armature driver, an inline call-noise-cancelling mic, passive noise isolation from the ear seal, and a metal body.
• jechan's biggest trade-off: a narrower 20 Hz–20,000 Hz range on paper, a USB Type-C connection that locks out older 3.5mm-only gear, and a 32 ohm impedance that asks a little more of weak sources.
• Pick Sony if you want simple plug-and-play bass from a brand you trust and you're feeding a 3.5mm socket.
• Pick jechan if clear calls in noisy places, isolation and a sturdier build matter more than brand familiarity.
Sony's pitch here is straightforward: a small, light in-ear with a 9mm neodymium dynamic driver and a claimed frequency range that runs from 5 Hz all the way up to 24 kHz. That low-end figure is the headline for bass fans — it's the kind of spec that suggests the driver is tuned to reach down for sub-bass rather than just pushing a mid-bass hump. Sony itself labels the theme "Deep Bass Sound," so the intent is clear.
The practical stuff is where it earns its keep. The earbuds use rounded silicone tips in a rounded-tip shape, which is the classic design for a secure, comfortable fit during long listening sessions. The cord is a Y-type flat design, which is genuinely useful if you've ever spent five minutes untangling a round cable before a commute. There's an inline mic and remote for taking calls and controlling playback without pulling your phone out, and the whole thing weighs about 3 grams — you'll forget you're wearing them.
Who should buy it? Anyone with a 3.5mm socket who wants a fuss-free bass-forward daily pair for music, podcasts and the odd call, and who values a familiar brand name. Who should skip it? If your phone only has USB-C, or if you ride loud trains and need the outside world muted, this isn't the pair — Sony lists noise control as "None," so you get zero active or passive cancellation beyond whatever the tip seal gives you. It's also plastic-bodied, so if you want a metal feel, look elsewhere.
jechan goes after a different buyer: someone who wants the bass boost and a clean mic. The spec sheet describes a dual-driver design with a balanced armature driver, balanced bass and treble tuning, and a claimed 102 dB sensitivity with a 32 ohm impedance. The frequency range is quoted as 20 Hz–20,000 Hz, and audio latency is listed at 0.5 milliseconds — a figure that matters more if you're using these for video or gaming than for plain music listening.
The real differentiator is the call handling. There's a built-in call-noise-cancelling mic that the brand says filters background clutter, paired with an ergonomic in-ear seal that creates passive noise isolation. That combination — a tight seal plus a mic tuned to reject noise — is exactly what you want on a busy train platform or in an open-plan office. The inline push-button controller handles playback and calls.
The build is the other selling point: a metal enclosure in dark brown, which should shrug off daily abuse better than plastic, and a lightweight ergonomic shape the brand pitches for all-day wear, workouts and travel. The trade-offs are real, though. The connection is USB Type-C, so anything with only a 3.5mm jack is out unless you have an adapter. The 32 ohm impedance means a weak built-in output won't drive them as loudly as a 16 ohm pair. And the quoted top end stops at 20 kHz, which is narrower on paper than Sony's 24 kHz — though in practice neither number tells you much about tuning.
Who should buy it? Commuters, office workers and anyone who takes a lot of calls in noisy rooms, plus people who want a metal-bodied pair. Who should skip it? Anyone still living on 3.5mm sockets, or someone who wants the absolute lowest-fuss option.
• Best for brand familiarity and simple setup → Sony Deep Bass Earphones. 3.5mm jack, inline mic, flat tangle-resistant cord, nothing to configure.
• Best for clear calls in noisy places → jechan Dynamic Balanced Deep. The call-noise-cancelling mic plus passive isolation is the whole point of this pair.
• Best for blocking out the world → jechan Dynamic Balanced Deep. Sony explicitly lists no noise control; jechan uses the ear seal for passive isolation.
• Best for newer USB-C phones → jechan Dynamic Balanced Deep. Its native connection is USB Type-C, so no dongle needed on modern handsets.
• Best for older phones, tablets and audio players → Sony Deep Bass Earphones. The standard 3.5mm plug works with the widest range of gear.
• Best for build feel → jechan Dynamic Balanced Deep. Metal enclosure versus Sony's plastic.
• Best for low-end extension on paper → Sony Deep Bass Earphones. A claimed 5 Hz floor against jechan's 20 Hz, and a lower 16 ohm impedance that's easier to drive.
• Best for video and gaming latency → jechan Dynamic Balanced Deep. Its 0.5 ms quoted latency is the more relevant figure for lip-sync.
Neither of these is objectively better; they're aimed at different sockets and different priorities. Check the current price on Amazon before you commit, since the value equation shifts depending on what each costs on the day you buy.
In my opinion, I'd buy the jechan Dynamic Balanced Deep if I were shopping today. The dual-driver setup, the call-noise-cancelling mic, the passive isolation from the seal and the metal body cover more of what actually goes wrong with cheap earbuds — muffled calls and a flimsy build — and the USB-C connection matches the phone I'd be plugging into. I'd only switch to the Sony Deep Bass Earphones if I needed a 3.5mm plug for older gear, wanted the lowest possible impedance for a weak source, or simply preferred buying from a name I already know. Both deliver bass; jechan just gives you more around it.
how is deep bass earbuds
Deep bass earbuds are in-ears tuned so the low frequencies — kick drums, basslines, sub-bass in electronic music — come through with weight rather than sounding thin. Both pairs here are explicitly marketed that way: Sony themes its model "Deep Bass Sound" with a claimed 5 Hz–24 kHz range, while jechan uses a dual-driver design with balanced bass and treble.
what is deep bass earbuds
The term describes in-ear headphones whose drivers and tuning emphasise low-end output. Sony uses a single 9mm neodymium dynamic driver; jechan uses a dual-driver arrangement with a balanced armature driver. The practical result is the same goal — more low-end presence than a basic pair — reached through different driver designs.
how to turn up bass on earbuds
Neither of these has a bass dial, so you raise low-end by other means: use your phone or player's equaliser and lift the lower bands, and make sure the tips seal properly in your ear canal, since a loose seal leaks bass away. jechan's passive isolation depends on that same tight seal, so fit matters for both sound and noise blocking.
is deep bass earbuds good
For most listeners, yes — extra low-end makes music feel fuller and more energetic. The trade-off is that heavy bass tuning can sometimes crowd out mids and vocals, and neither of these pairs offers active noise cancellation, so deep bass won't help you on a loud train. If you want bass plus real quiet, jechan's passive isolation gets you closer than Sony's model, which lists no noise control at all.
