How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a complete, plug-and-play USB-C in-ear monitor with a mic built into a single set, choose YINYOO CCZ DC01; if you need a smart gaming cable that upgrades an existing pair of 0.78mm 2-pin IEMs with a DAC, DSP and a detachable boom mic, choose Linsoul Kiwi Ears S-Link.
• YINYOO CCZ DC01 — biggest strength: it's a finished product. One USB-C earbud with a built-in inline media control and mic, a dynamic driver tuned for punchy bass, and ear-fin tips designed to keep the fit locked in.
• YINYOO CCZ DC01 — biggest trade-off: it's a closed system. You get the sound the driver gives you, with no EQ modes, no DSP, and no way to swap microphones.
• Linsoul Kiwi Ears S-Link — biggest strength: it's a cable, not a headphone. You bring your own IEMs and it adds a DAC chipset with DSP, three sound modes, dual microphones and a smart touch control system.
• Linsoul Kiwi Ears S-Link — biggest trade-off: it only works if you already own (or plan to buy) IEMs with a 0.78mm 2-pin connector. Plug it into nothing and it does nothing.
• For the buyer who wants one purchase and done: YINYOO CCZ DC01.
• For the buyer who already owns IEMs and wants to make them smarter: Linsoul Kiwi Ears S-Link.
The CCZ DC01 Pro is the simpler answer to "I want wired USB-C earbuds that just work." It's a self-contained in-ear monitor: a redesigned dynamic driver inside a TPE-shelled housing, wired straight to a USB-C plug, with media controls on the cable and a microphone built in. The numbers tell a story of easy drivability — 22 ohm impedance and 110 dB sensitivity — which means a phone or tablet should push it to loud, clean levels without a separate amp. Frequency range runs the standard 20–20,000Hz.
The tuning is aimed at fun, not neutrality. The description leans hard on bass — "super bass," "punchy," "enveloping" — and that's consistent with a single dynamic driver design at this price-agnostic spec level. That's the right call for gaming, action movies, and pop or electronic music where low-end weight matters more than flat response. The included ear-fin ear tips are the other practical detail worth noting: they're there to hold the bud in place during movement, which is exactly what you want in a gaming session or a commute.
Linsoul Kiwi Ears S-Link: Who It's For
The S-Link is a different category of product entirely, and it's worth being blunt about that. This is a 1.2m silver-plated cable with a USB-C plug on one end and a 0.78mm 2-pin connector on the other. It is not a headphone. If you don't have IEMs to attach it to, this is not your product.
What it offers is control. Inside is a dedicated DAC chipset with a mini DSP, which lets the cable do two things: clean up and drive your IEMs' signal, and reshape their sound signature through EQ. That's paired with a three-mode smart control system — Normal, Game and Hi-Fi — that switches the DAC's settings depending on what you're doing. Normal for everyday listening, Game for positional clarity, Hi-Fi when you want the fullest presentation your IEMs can give.
Then there's the microphone situation, which is genuinely the headline. You get two: a built-in inline mic on the cable, and a detachable boom mic you can clip on when you need it. The smart controls let you switch between them on the fly, along with volume, play/pause, track skipping, call handling, and mic mute. The boom mic is directional, so according to the product information it focuses on your voice and cuts down on keyboard clatter and room echo — the single most common complaint about gaming on a plain inline mic.
Small details that matter: the 2-pin connectors are color-coded red for right and blue for left, so you can't install them backwards. The cable is about 1.25m, which is the sweet spot for phone, desk and commute use — long enough to reach a PC tower, short enough not to snag. Controls are touch-based rather than clicky buttons.
Who should buy it? IEM owners who game on mobile or PC and want one cable that handles audio, voice and control. Also anyone who wants to experiment with EQ without buying new headphones. Who should skip it? Anyone without 2-pin IEMs, and anyone who wants a single self-contained earbud and doesn't want to think about connectors.
• Best for a one-purchase, works-out-of-the-box setup → YINYOO CCZ DC01. Earbuds, cable, mic and tips all arrive together.
• Best for upgrading IEMs you already own → Linsoul Kiwi Ears S-Link. It turns a passive pair into a DSP-driven, EQ-capable, three-mode setup.
• Best for voice clarity in games and calls → Linsoul Kiwi Ears S-Link. The detachable directional boom mic is purpose-built for exactly this, and you can switch to the inline mic when you'd rather travel light.
• Best for bass-forward, plug-and-play listening → YINYOO CCZ DC01. A single dynamic driver explicitly tuned for punchy low end.
• Best for adjustability → Linsoul Kiwi Ears S-Link. Three sound modes plus DSP EQ tuning versus a fixed tuning on the DC01.
• Best for fit security during movement → YINYOO CCZ DC01. The patent ear-fin tips are designed to keep the bud seated.
• Best for connection reliability → YINYOO CCZ DC01. No 2-pin joint to worry about; the driver and cable are one unit.
• Best for tinkerers and audiophiles → Linsoul Kiwi Ears S-Link. Silver-plated wire, DAC chipset, and a connector standard that lets you rotate IEMs in and out.
In my opinion, most people searching this comparison should buy the YINYOO CCZ DC01. It's the lower-friction decision: one product, one USB-C plug, and you're listening and talking. It suits gaming, commuting and laptop calls without asking you to own anything else first.
I'd recommend the Linsoul Kiwi Ears S-Link specifically to IEM owners who game and want a boom mic, EQ modes and a DAC in one cable. If that's you, it's the more capable tool by a wide margin. If it isn't, it's the wrong shape of product entirely. Check the current price on Amazon for whichever one matches your situation before you commit.
They're not the same kind of product, so "better" depends on what you own. The DC01 is a complete USB-C IEM with a mic. The S-Link is a replacement cable for existing 0.78mm 2-pin IEMs. If you have no IEMs, the S-Link can't help you.
No. It's a cable only — a 1.2m silver-plated wire with USB-C on one end and 0.78mm 2-pin connectors on the other. You supply the in-ear monitors.
The Linsoul Kiwi Ears S-Link, based on its design. It offers both an inline mic and a detachable directional boom mic, and the boom mic is built to focus on your voice and reduce keyboard and room noise. The DC01 has a single built-in mic.
Usually, but not always without a settings tweak. Some Android phones need "disable USB audio routing" turned off in developer options, and some desktops default to speakers until you manually select USB as the output device.
Only on the S-Link. It has a DAC with DSP and three modes — Normal, Game and Hi-Fi. The YINYOO CCZ DC01 has a fixed tuning with no EQ controls.
