If you want a single USB-C wired earbud built around call clarity and deep bass with a metal build, choose BACKWIN USB C; if you need maximum sensitivity, wider device compatibility and the lowest latency figure on the sheet, choose jechan Earphones Rich Bass.
• BACKWIN USB C — biggest strength: Dual-driver design (10mm dynamic plus a balanced armature) paired with ENC call noise reduction and a full 20 Hz – 20,000 Hz frequency range, so deep bass and clear speech are both covered.
• BACKWIN USB C — biggest trade-off: USB-C only, so older 3.5mm gear is out, and it runs a lower 96 dB sensitivity than the jechan.
• jechan Earphones Rich Bass — biggest strength: 108 dB sensitivity and a 0.5 ms latency figure, which points to easier driving and tighter sync for video and calls.
• jechan Earphones Rich Bass — biggest trade-off: Smaller 20 KHz frequency response figure on the sheet and a lighter 1 oz build that leans plastic-light rather than dense.
• Who each pick is for: BACKWIN for USB-C-only phone and laptop users who take calls in loud places; jechan for buyers who want a bass-forward bud that also plays nice with whatever jack they have.
The BACKWIN USB C is the bud for someone whose listening life already lives on USB-C. No dongle, no adapter, no "where did I put that little cable" moment. Plug straight into a modern Android phone, a laptop, a tablet, and it just works. The Type-C connector is the entire connectivity story here, and for most people buying a phone in the last few years, that's exactly the right call.
What it does best is the combination of bass and voice. You get a 10mm driver working alongside a balanced armature, and the sheet lists a frequency range of 20 Hz to 20,000 Hz. That low end matters. The 20 Hz floor is where the rumble lives — kick drums, bass guitar, the thump under a hip-hop or EDM track. The balanced armature is the other half of the story, handling the detail and clarity that a dynamic driver alone often smears. Add ENC call noise reduction and an inline push-button control for volume, playback and calls, and you have a bud built for the commute, the open-plan office, the noisy train platform.
Who should buy it: USB-C device owners who want deep bass and genuinely usable call quality in one wired package, and who like the idea of a metal housing with a 1-year warranty and a set of S/M/L ear tips in the box. Who should skip it: anyone still carrying a 3.5mm-only device, or anyone who prioritizes the highest possible sensitivity figure over call-focused noise reduction. It's a black, in-ear, metal-bodied workhorse — not a fashion statement, and it isn't trying to be.
The jechan Earphones Rich Bass is aimed at the buyer who wants bass first and flexibility second. The title itself leads with "Rich Bass," and the sheet backs the intent: a dual-driver setup of one dynamic plus one balanced armature (1DD+1BA), 32 ohm impedance, and a sensitivity of 108 dB. That sensitivity number is the standout. Higher sensitivity means the bud needs less push from your source to hit a given loudness, which is genuinely useful on phones and laptops with modest output.
The latency figure of 0.5 milliseconds is the other detail worth pausing on. For wired audio that's effectively instant, which matters if you're using these for calls, conferencing, or anything where lip-sync and voice timing matter. The ENC setup here is powered by an AI recording chip, and the sheet specifically calls out an HD microphone for calls and recording — so the pitch is bass plus clean voice capture.
Build-wise you get a metal housing described as drop-resistant, finished in brown, with an inline remote for volume. The sheet also lists a USB Type-C connection, and the description references broad compatibility with both USB-C and 3.5mm devices. Note that the structured connectivity field lists USB Type-C only, so treat the 3.5mm compatibility as a claim from the description rather than a spec field. Who should buy it: bass-forward listeners who want an easy-to-drive bud and a rugged metal shell. Who should skip it: anyone who needs the lowest possible bass extension, since the sheet lists a 20 KHz frequency response figure rather than a deep 20 Hz floor.
Side-by-Side: Which Should You Choose?
• Best for deep, extended bass → BACKWIN USB C. Its sheet lists a 20 Hz – 20,000 Hz range, and 20 Hz is the floor where sub-bass actually lives.
• Best for call noise reduction in busy places → BACKWIN USB C. It lists Active Noise Cancellation, Environmental Noise Cancellation and sound isolation together.
• Best for low-latency video and voice work → jechan Earphones Rich Bass. The 0.5 ms latency figure is the tighter number on the sheet.
• Best for a rugged metal shell → jechan Earphones Rich Bass. Drop-resistant metal housing is called out specifically.
• Best for USB-C-only simplicity → BACKWIN USB C. One connector, no ambiguity, no adapter.
• Best for built-in tip options → BACKWIN USB C. It ships with S/M/L ear tips, which matters for fit and therefore for bass seal.
• Best for a lighter, less bulky carry → jechan Earphones Rich Bass. Roughly 1 oz versus 125 g on the BACKWIN sheet.
In my opinion, if deep bass is the whole reason you're shopping, I'd buy the BACKWIN USB C. The 20 Hz low-end figure, the dual-driver setup, the metal body and the triple-layer noise story (ANC plus ENC plus isolation) line up with exactly what a bass-first, call-heavy buyer wants. The jechan is the better pick if your priority is sensitivity and latency over raw low-end extension, or if you want the lighter, drop-resistant build. But for the "headphones with deep bass" need that brought most people to this page, BACKWIN is my recommendation.
what are headphones with good bass
Good bass comes from a driver that can move air at low frequencies and a housing that seals well in your ear. On paper, that means a low frequency-response floor — the BACKWIN USB C lists 20 Hz, which is the kind of number bass lovers look for. Fit matters just as much, which is why included S/M/L ear tips help.
what headphones have deep bass
Deep bass is about how far down the frequency range reaches. The BACKWIN USB C lists 20 Hz – 20,000 Hz, so its sheet explicitly covers the sub-bass region. The jechan Earphones Rich Bass is marketed around rich bass with a 1DD+1BA driver setup, but its sheet lists a 20 KHz frequency response figure rather than a low-end floor.
what is bass in headphones
Bass is the low-frequency part of the audio signal, roughly the bottom of the audible range, where kick drums and basslines sit. A driver size of 10mm, which both of these buds share, is a common size for in-ear bass output. Impedance of 32 ohm on both also means they're designed to work with typical phone and laptop outputs.
what are earbuds with good bass
Earbuds with good bass combine a low frequency floor, a decent seal and enough sensitivity to be driven properly. The BACKWIN USB C offers a 20 Hz floor and 96 dB sensitivity with ENC; the jechan Earphones Rich Bass offers higher 108 dB sensitivity for easier loudness. Which one wins for you depends on whether you want deeper extension or easier drive.
