How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a comfortable, low-impedance all-rounder that plays nicely with almost anything you own and comes with genuinely unusual eartips, choose TANGZU Wan'er S.G II; if you need a bass-forward, wide-stage set built for immersive gaming and Hi-Res listening with a sturdier resin-and-metal build, choose TINHIFI C1.
• TANGZU Wan'er S.G II — biggest strength: A refined 10mm PET diaphragm driver with a 19Ω impedance that pairs easily with phones, consoles and Hi-Res players, plus patented Tang Sancai eartips that shape the sound path.
• TANGZU Wan'er S.G II — biggest trade-off: Passive noise cancellation only, and the driver tech is a PET diaphragm rather than the harder DLC material — so it leans smooth and natural rather than hyper-detailed.
• TINHIFI C1 — biggest strength: A 10mm DLC composite diaphragm with a dual magnetic circuit and dual cavity design, giving fast transients, deep bass and a wide soundstage.
• TINHIFI C1 — biggest trade-off: Higher 22Ω impedance and no inline noise control, so it asks a little more from your source and isolates less on its own.
• Who each is for: Pick the Wan'er S.G II if you want comfort, easy driveability and a balanced, fatigue-free listen across many devices. Pick the C1 if you want punchy bass, an expansive stage and a premium resin-and-metal build for gaming and critical listening.
The Wan'er S.G II is the second generation of a well-known budget IEM, and the changes here are mostly about refinement rather than reinvention. The headline is an upgraded 10mm PET diaphragm dynamic driver paired with a reworked driver chamber. In practice, that combination points toward a clean, natural tonality with low distortion — the kind of tuning that doesn't shout at you. PET is also a hypoallergenic material, which matters if your ears get irritated after long sessions.
Where this set really shines is flexibility. The impedance is just 19Ω, which is genuinely low, and that means it will play loud and clean from almost anything: a phone dongle, a PC, a gaming console, a Hi-Res player, or a high-current headphone amp. You don't need to build a chain around it. The 0.78mm flat 2-pin connector adds a detachable, silver-plated copper cable you can swap or upgrade later, and the recessed flat design is a common standard, so aftermarket cables are easy to find.
Comfort is clearly a design priority. The housing was sculpted around ergonomic feedback for a secure, fatigue-free fit, and that also helps with isolation. TANGZU's own Tang Sancai eartips use a filter-zone design that the brand says optimizes the sound pathway and cuts distortion compared to ordinary silicone tips. There's also a mic and media controls on the 3.5mm version, which is a real convenience for calls and gaming chat.
TINHIFI C1: Who It's For
The C1 takes a different angle: it's built around a 10mm DLC composite diaphragm. Diamond-like carbon is hard and light, and that combination is what gives it fast transient response and high-resolution detail — the reason DLC shows up in more expensive gear. TINHIFI pairs it with a dual magnetic circuit and a dual cavity structure that manages airflow for tighter driver control and more authoritative bass. Front and rear tuning ports further shape low-frequency response and stage width.
That tuning is the C1's personality. The bass is described as deep and textured, which is exactly what makes explosions and gunshots land in FPS games, and the stage is wide enough to help with positional cues. If you split your time between music and gaming, this is the more dramatic of the two. The 22Ω impedance is still low enough for phones and laptops, but it's slightly higher than the Wan'er, so a stronger source gets a bit more out of it.
The build is a step up in feel. You get a CNC metal faceplate over a medical-grade resin shell, gold-plated connectors, and multiple ear tip sizes plus cable management accessories. TINHIFI also highlights the curved, zero-pressure shell as comfortable for side-sleeping — a niche but genuinely useful trait if you listen in bed. A Type-C version with a built-in mic and Hi-Fi DAC is available for people who want to plug straight into a phone or laptop with no adapter. It also carries a 1-year warranty and goes through multi-stage QC including frequency calibration, burn-in, connector durability and drop testing.
Buy it if you want bass impact, a wide soundstage, a premium-feeling shell and gaming-ready imaging. Skip it if you want the lowest possible impedance, an inline mic on the 3.5mm version, or you prefer a neutral, easygoing tuning over a bass-forward one.
• Best for easy driveability → TANGZU Wan'er S.G II. At 19Ω it's the lower-impedance of the two and will sing from weak sources like a phone or controller jack.
• Best for bass and gaming immersion → TINHIFI C1. The DLC diaphragm, dual magnetic circuit and tuned ports are aimed squarely at deep bass and a wide, positional stage.
• Best for long-session comfort → TANGZU Wan'er S.G II. Hypoallergenic PET driver material, an ergonomically reshaped housing, and the Tang Sancai eartips all point to fatigue-free wear.
• Best for side-sleeping and travel → TINHIFI C1. The zero-pressure curved shell and lightweight build are explicitly designed for pillow use.
• Best for calls and inline control → TANGZU Wan'er S.G II. The 3.5mm version includes a mic and button media controls; the C1's standard 3.5mm has no inline noise control.
• Best for a premium build and accessories → TINHIFI C1. CNC metal faceplate, medical-grade resin shell, gold-plated connectors, multiple tips and a 1-year warranty.
• Best for plug-and-play with modern phones → TINHIFI C1 (Type-C version). Built-in Hi-Fi DAC and mic mean no dongle needed.
• Best for balanced, natural tonality → TANGZU Wan'er S.G II. The refined PET driver and chamber are tuned for clarity and natural timbre rather than thump.
In my opinion, the right pick comes down to what you'll actually be doing. If you want a comfortable, neutral-leaning set that plugs into anything and disappears in your ears for hours, I'd buy the TANGZU Wan'er S.G II — the 19Ω impedance, ergonomic shell and Tang Sancai eartips make it the more versatile daily driver. If you're a gamer or a bass lover who wants a wide stage, punchy low end and a more premium-feeling shell, I'd take the TINHIFI C1 instead. Neither is objectively better; they're tuned for different listeners.
Not universally. The Wan'er S.G II is easier to drive at 19Ω and more comfort-focused, while the C1 uses a harder DLC diaphragm with a dual magnetic circuit for faster detail and deeper bass. Which is "better" depends on whether you value balance and comfort or bass and stage.
The TANGZU Wan'er S.G II has the lower impedance at 19Ω versus 22Ω on the C1, and higher sensitivity at 113.5dB versus 108dB. Both are phone-friendly, but the Wan'er will reach the same volume with a bit less power.
Yes, both. The TINHIFI C1 leans into gaming with a wide soundstage and bass that makes in-game explosions and footsteps stand out. The Wan'er S.G II is a solid all-rounder for gaming thanks to its low impedance and comfortable fit for long sessions.
The 3.5mm TANGZU Wan'er S.G II includes a mic and button media controls, and uses passive noise cancellation from its seal. The TINHIFI C1's 3.5mm version lists no inline noise control, but a Type-C version with a built-in mic and Hi-Fi DAC is available. If a mic matters most, check the exact variant before buying — and if price matters, check the current price on Amazon.
