If you want a wired on-ear headphone that doubles as a headset for calls and everyday phone listening, choose Audio-Technica ATH-S120C-LV; if you need a cable-replaceable in-ear earphone built for pure music listening with a 3.5mm jack, choose Yechiry Earphone.
• Audio-Technica ATH-S120C-LV — biggest strength: USB-C connectivity with an inline mic and full media/call controls, so one cable handles music, volume, track skipping and phone calls.
• Audio-Technica ATH-S120C-LV — biggest trade-off: It's wired and locked to USB-C devices, and it's an on-ear design rather than an in-ear one.
• Yechiry Earphone — biggest strength: A detachable 4-strand oxygen copper cable that you can swap out, paired with a 3.5mm plug that fits a huge range of gear.
• Yechiry Earphone — biggest trade-off: No microphone, and the connection is 3.5mm only, so USB-C-only phones need an adapter.
• Who Audio-Technica ATH-S120C-LV is for: Anyone taking calls and listening from a USB-C phone, tablet or laptop who wants controls right on the cable.
• Who Yechiry Earphone is for: Music-first listeners on 3.5mm devices who value a replaceable cable and a deep-bass, detailed tuning.
The ATH-S120C-LV is a wired on-ear headphone that connects over USB-C. That single detail shapes everything about it. Because the signal and the controls travel down the same USB-C cable, you get an inline remote and microphone that handle play/pause, track skipping, volume and answering or ending calls. You never have to pull your phone out of a pocket or bag to change a song or take a call. For commuters, remote workers and students who live on a laptop or a USB-C phone, that's a genuinely useful setup.
Comfort and portability are clearly part of the design brief. The headphones are lightweight and compact, and the housings fold flat, which makes them easy to slip into a bag between uses. Audio-Technica rates the drivers as dynamic with a 20 Hz – 20,000 Hz frequency range, 35 ohm impedance and 103 dB sensitivity — a combination that suggests they're easy to drive from a typical USB-C source without needing extra amplification. The on-ear earpieces use fabric and silicone materials, and the brand describes the fit as comfortable for extended sessions, which matters if you wear them through a long workday or a full season of a show.
Who should skip it: anyone with a 3.5mm-only device, since there's no 3.5mm option here. If you want the isolation of an in-ear seal, or you specifically want a user-replaceable cable, this isn't that product. And if you never take calls and just want the simplest possible music-only setup, you're paying for controls and a mic you won't use.
Yechiry Earphone: Who It's For
The Yechiry Earphone takes the opposite approach. It's a wired in-ear earbud with a 3.5mm plug, and its defining feature is the detachable cable — a 4-strand oxygen copper design the brand says is anti-interference and easy to replace. That's the practical win: if a cable frays or breaks, you swap the cable instead of the whole earphone. Yechiry also frames the detachable design as reducing stethoscope effect, skin effect and proximity effect, which is the kind of cable-noise chatter you get when a cord rubs against clothing.
On sound, the brand positions it for a wide, balanced, coherent signature with powerful bass, open mids and extended highs, and describes it as a pick for audiophiles, DJs and singers. That's marketing language, but the intended character is clear: a full-range, bass-forward tuning rather than a thin, flat one. Note one important omission — this model is sold without a microphone. It is a listening earphone, not a headset, so you can't take calls on it.
Compatibility is broad. The 3.5mm jack works with smartphones, laptops, tablets, MP3 players and devices running Android, iPod and Windows. That universality is the real selling point: a 3.5mm plug fits almost everything older or non-USB-C, and if your phone has dropped the headphone jack, a cheap adapter bridges the gap. The trade-off is exactly that — on a USB-C-only phone you'll need that adapter, and you lose inline call controls entirely because there's no mic.
Who should buy it: listeners who treat music as the main event, own 3.5mm-capable gear, and want a replaceable cable as insurance against the most common failure point in any wired earphone. Who should skip it: anyone who needs to take calls, or who wants the simplicity of plugging straight into a USB-C phone with controls on the cable.
Side-by-Side: Which Should You Choose?
• Best for USB-C phones, tablets and laptops → Audio-Technica ATH-S120C-LV. The USB-C connector is the native fit, no adapter required.
• Best for older or mixed 3.5mm devices → Yechiry Earphone. The 3.5mm jack covers smartphones, laptops, tablets, MP3 players and more.
• Best for replacing a worn cable → Yechiry Earphone. The detachable 4-strand oxygen copper cable is user-swappable; the Audio-Technica cable is fixed.
• Best for on-ear comfort over long sessions → Audio-Technica ATH-S120C-LV. Lightweight, compact and foldable, with fabric and silicone earpieces.
• Best for bass-forward, detailed music listening → Yechiry Earphone. Its stated tuning emphasizes powerful bass, open mids and extended highs.
• Best for travel and storage → Audio-Technica ATH-S120C-LV. The housings fold flat, so they pack down easily.
• Best for a distraction-free, music-only setup → Yechiry Earphone. No controls or mic to fiddle with — just plug in and listen.
If I had to pick one, I'd buy the Audio-Technica ATH-S120C-LV. In my opinion it's the more versatile tool: one USB-C cable gives you music, volume, track control and hands-free calls, and the fold-flat on-ear design is comfortable and easy to carry. The 2-year warranty and iOS/Android compatibility seal it for everyday use across a phone and a laptop. I'd only steer you to the Yechiry Earphone if your devices use 3.5mm, you never take calls, and you specifically want a cable you can replace yourself. That's a real advantage — just for a narrower job.
"Better" depends on your devices. The Audio-Technica wins for USB-C gear and calls thanks to its inline mic and controls. The Yechiry wins for 3.5mm devices and cable replacement. They're built for different setups, not the same one.
No. This model is sold without a microphone, so it's for listening only. If you need to take calls or use voice chat, the Audio-Technica ATH-S120C-LV is the one with an inline mic and call controls.
No — it connects over USB-C only. If your phone or laptop has a 3.5mm jack and no USB-C port, the Yechiry Earphone is the more direct fit. Check the current price on Amazon before deciding, since both sit in different budget tiers.
Both have a clear weak point worth weighing. The Yechiry's detachable cable can be replaced if it fails, which is a genuine longevity advantage. The Audio-Technica's cable is fixed, but it folds flat for storage and carries a 2-year warranty. In my opinion, the replaceable cable is the better long-term bet for heavy wired use.
