If you want to plug two pairs of headphones into one USB-C device and share the same audio with someone sitting next to you, choose MOSWAG Type C; if you need to keep listening while your phone charges, choose Quanlex 2. Those are two genuinely different jobs, and that single difference decides the whole comparison.
• MOSWAG Type C — biggest strength: it turns one USB-C port into two 3.5mm outputs, so two people hear the exact same audio at the same time. That's the entire point of the product, and nothing else in this matchup does it.
• MOSWAG Type C — biggest trade-off: there is no charging passthrough. It's an audio splitter only, so you can't top up your phone while it's connected.
• Quanlex 2 — biggest strength: it splits one USB-C port into a 3.5mm jack and a PD charging port, with a 32-bit/384kHz DAC and support for up to 60W PD charging. Listen and charge at once.
• Quanlex 2 — biggest trade-off: only one audio output. It solves the battery problem, not the sharing problem. Data transfer isn't supported either.
• Who each pick is for: MOSWAG Type C for couples, kids studying together, travel companions and anyone splitting one screen between two listeners. Quanlex 2 for a single user on a long flight, a commute or a gaming session who refuses to choose between sound and battery.
MOSWAG Type C is a Y-splitter, and it's honest about it. One USB-C plug goes into your phone, tablet or laptop, and two 3.5mm female jacks come out the other end. Both connected headsets get the same audio feed simultaneously. That's a narrow feature set, but for the people who need it, nothing else in this comparison comes close.
The build is aimed at daily handling rather than showroom looks. The connector is described as tight and resistant to loosening, with the manufacturer citing 500+ unplug cycles without damage. The shell is aluminum alloy, the cable is nylon braided and tangle-resistant, and the surface is described as fireproof and waterproof. The whole thing weighs about 0.02 kg — effectively nothing in a bag. Inside, MOSWAG points to an amplifier chip meant to raise output so quieter sources come through louder and clearer, which matters in the classroom-style scenario the brand describes: two kids on one online lesson, both needing to hear the teacher.
Compatibility is broad on the USB-C side: iPhone 15 and 16 families, recent iPad Pro, Air and Mini models, MacBook and MacBook Pro, and a long list of Samsung Galaxy phones and tablets, plus other USB-C audio devices. One caveat worth repeating because it catches people out: this is an audio splitter, not a charger. Don't buy it expecting power.
Buy it if you regularly want two people on one device — movie nights on a tablet, shared playlists on a flight, siblings in the same online class. Skip it if you're a solo listener, or if running your phone down while you listen is the problem you're actually trying to solve.
Quanlex 2 attacks the opposite problem. Its two ports are a 3.5mm audio jack and a USB-C PD charging port, so you can listen through wired headphones while the phone keeps charging. If you've ever watched your battery drop during a long call or a cross-country flight with wired earbuds in, that's the exact frustration this adapter is built around.
The audio side leans on a 32-bit/384kHz DAC with built-in noise cancellation, and Quanlex claims high-resolution output with in-line control support — meaning your headset's volume and call buttons should still work. It's plug-and-play: no drivers, no apps. The charging side supports up to PD 60W and is described as compliant with PD, QC, AFC and PPS standards; a separate bullet also mentions PD 27W charging for certain devices, so the honest read is that charging speed depends on your device and wall charger. The brand notes you should use a PD wall charger for the faster results. Data transfer is not supported.
The physical design is where Quanlex 2 gets interesting. Alongside the aluminum alloy shell and braided nylon cable, there's a magnetic suction connection that Quanlex says makes the joint stronger, reduces cable tearing and helps heat dissipation — with 15,000+ durability test cycles cited. Compatibility covers iPhone 16 and 15 families, iPad Pro/Air 2020–2024, iPad mini, MacBook Pro/Air 2024, Huawei Mate 60 Pro, a wide spread of Galaxy S and Note models, Google Pixel 2 through 9, LG V40 and more. It also carries a 1-year warranty, and it's black.
Buy it if you're one person who wants wired audio without babysitting your battery — travel, gaming, long calls, desk work. Skip it if two people need to hear the same thing, because it only has one audio output.
Side-by-Side: Which Should You Choose?
• Best for listening while charging → Quanlex 2. That's its core function, up to PD 60W depending on your device and charger.
• Best for a solo traveler or commuter → Quanlex 2. One listener, long hours away from an outlet.
• Best for families, tutors and study sessions → MOSWAG Type C. The boosted output and dual jacks suit two people on one lesson.
• Best for audio purists who care about the DAC spec → Quanlex 2. A 32-bit/384kHz DAC with noise cancellation is the more explicitly audiophile-oriented design here.
• Best for wired-call convenience → Quanlex 2. In-line control support means your headset buttons should keep working.
• Best for pure simplicity → MOSWAG Type C. Plug in, two people hear it. No charging standards, no wall-charger caveats.
• Best durability story → a near tie. Both use aluminum shells and braided nylon; MOSWAG cites 500+ unplug cycles, Quanlex cites 15,000+ cable test cycles. Different tests, both pointing at long service life.
In my opinion, the deciding question isn't which adapter is better built — both look solid — it's what you're actually doing with your phone. If you're buying for yourself, I'd take Quanlex 2. Listening while charging solves a problem you hit constantly, and the DAC spec and in-line control make it the more capable everyday adapter. I'd only switch to MOSWAG Type C if my real need was two people on one device, because Quanlex 2 simply can't do that job. Buy for the job, not the spec sheet. And since neither product's price is fixed, check the current price on Amazon before you commit.
FAQ
Quanlex 2. It splits your USB-C port into a 3.5mm jack plus a PD charging port supporting up to 60W, while MOSWAG Type C is an audio-only splitter with no charging passthrough at all.
No. Quanlex 2 has a single 3.5mm output, so only one headset connects. For two listeners on the same audio, you want MOSWAG Type C and its dual 3.5mm jacks.
Quanlex 2 is the more explicitly specified audio design, with a 32-bit/384kHz DAC and noise cancellation. MOSWAG Type C instead focuses on adding amplifier output so two listeners hear louder, clearer audio — a different goal rather than a strictly lesser one.
Yes. Both list support for the iPhone 15 and 16 families, recent iPads, MacBooks, and a broad range of Samsung Galaxy phones and tablets, along with other USB-C audio devices. Check your specific model against the compatibility list before buying.
