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 wired USB-C earbud you can pull out of a bag and use immediately, choose Gsangoo USB C Headphones; if you need to charge your phone and keep listening through your own 3.5mm earphones at the same time, choose Stouchi 2-in-1. These two products are not really rivals — one is a finished pair of headphones, the other is a tiny adapter that turns a USB-C port into two ports. The right answer depends entirely on what you already own and what problem you are trying to solve.
• Biggest strength of Gsangoo USB C Headphones: a complete plug-and-play wired earphone with a built-in microphone, a digital DAC chip and a 3-button remote, so nothing else is required.
• Biggest trade-off of Gsangoo: you are locked into the included earbuds, and there is no active noise cancellation — the noise control field is explicitly "None."
• Biggest strength of Stouchi 2-in-1: one USB-C port becomes two, letting you charge at up to 9V/3A (30W) while feeding audio to a 3.5mm headphone jack, with a Hi-Res DAC rated at 24bit/96KHz.
• Biggest trade-off of Stouchi: it is just an adapter — no earbuds, no microphone, and it only helps if you already own a pair of 3.5mm headphones.
• Buy Gsangoo USB C Headphones if you want one purchase that ends the "my phone has no headphone jack" problem today.
• Buy Stouchi 2-in-1 if you already love a wired 3.5mm headset and refuse to give up charging while you use it.
The Gsangoo USB C Headphones are a self-contained solution. You get a pair of semi-in-ear wired earbuds with rounded tips, a flexible TPE cord, a built-in microphone and a 3-button remote for call and track control. The audio side runs a dynamic driver covering 20 Hz to 20,000 Hz, and the description credits a "latest digital DAC chip" for stereo transmission and clearer calls. In practical terms, that means the headphone does the digital-to-analog conversion inside the plug, which is exactly why it can work on phones that dropped the 3.5mm jack.
Who should buy it? Anyone who wants a lightweight, pocketable wired earphone for calls, podcasts and commute listening, and who does not want to carry a dongle. The package even includes anti-drop earplugs and a drawstring bag, and the item weight is listed at just 0.03 kg. Who should skip it? If you need active noise cancellation, this is not that product — noise control is listed as none, and noise isolation only comes from the tip fit. If you already own a great pair of 3.5mm headphones, buying a second set of earbuds may be redundant.
Stouchi 2-in-1: Who It's For
The Stouchi 2-in-1 is a completely different animal. It is a small red adapter with two ports: one USB-C that plugs into your phone or tablet, and a 3.5mm audio jack for your own wired earphones or headphones. The point is simultaneous use — charge and listen at once, which is the exact scenario that frustrates anyone who switched to a jackless phone and still prefers wired audio.
The charging side is the headline feature. The built-in PD chip pushes power up to 9V/3A, which the listing describes as 30W fast charging. That matters most during long calls, gaming sessions or movie marathons where a dongle-only setup would leave you choosing between battery and audio. The audio side uses a Hi-Res DAC rated at 24bit/96KHz and is compatible with both CTIA and OMTP wiring standards — a detail that matters because older headsets sometimes use the other standard and end up with silent or garbled microphones.
Compatibility is again wide: iPhone 17/16/15 Pro Max and siblings, iPad Air 5th and 4th gen, a large spread of Samsung Galaxy S and Note models, Z-Flip, Pixel 9 down to Pixel 2, iPad Pro and Mini 6, and Huawei P40 and Mate 40/30 Pro lines. The adapter is described as mini and lightweight, with lifetime technical support from the manufacturer.
Side-by-Side: Which Should You Choose?
• Best for a complete, ready-to-use kit → Gsangoo USB C Headphones. Earbuds, mic, remote and DAC are all included in one cable.
• Best for keeping your own headphones → Stouchi 2-in-1. It accepts any 3.5mm headset and adds a charging passthrough.
• Best for long sessions where battery dies → Stouchi 2-in-1. 9V/3A PD charging while audio plays is the whole reason this product exists.
• Best for phone calls without extra hardware → Gsangoo USB C Headphones. Built-in microphone and 3-button remote, though iPhone 15/16 users must enable "Reduce Audio Loudness" first.
• Best for higher-resolution audio spec → Stouchi 2-in-1. The 24bit/96KHz DAC figure is the more explicit audio specification of the two.
• Best for travel and pocket carry → Gsangoo USB C Headphones. A single lightweight cable at 0.03 kg beats carrying an adapter plus a separate headset.
• Best for mixed old and new gear → Stouchi 2-in-1. CTIA and OMTP support means it plays nicely with headsets of different vintages.
• Best for noise isolation → neither, strictly speaking. Gsangoo relies on tip fit with no active noise control; Stouchi passes through whatever your own headphones provide.
In my opinion, the Gsangoo USB C Headphones are the smarter buy for most people, because they solve the problem in one step: plug in, and you have audio, a mic and controls. The Stouchi 2-in-1 is the better choice only if you are emotionally attached to a specific pair of 3.5mm headphones and cannot live without charging while you listen. If that describes you, the Stouchi is genuinely excellent at its one job. Otherwise, buy the Gsangoo and move on. Check the current price on Amazon before deciding, since these two products sit in very different budget brackets.
They do different jobs, so "better" depends on you. Gsangoo gives you finished earbuds with a mic and remote; Stouchi gives you charging plus a 3.5mm jack for headphones you already own.
Yes, but the listing states that calls require you to enable "Reduce Audio Loudness" under Settings, then Sound and Haptics, then Headphone Security on iOS.
Yes — that is the core design. It supports PD fast charging up to 9V/3A alongside a 3.5mm audio jack, so you can charge and listen simultaneously.
The Stouchi quotes a 24bit/96KHz Hi-Res DAC, while Gsangoo quotes a digital DAC chip with a 20 Hz–20,000 Hz dynamic driver. On paper the Stouchi's DAC spec is higher, but the final result also depends on the headphones you plug into it. Compare the current prices on Amazon before you commit.
