If you want a wired adapter that lets you keep a 3.5mm headphone plugged in while your phone fast-charges at up to 60W, choose JSAUX USB C; if you need standalone wireless earbuds with a charging case that refills over USB-C fast charging, choose DCBCODGAL Earbuds.
• JSAUX USB C — biggest strength: a single USB-C port split into a 60W PD charging passthrough plus a 3.5mm audio jack, so you charge and listen at the same time with a Smart DAC chip handling the audio.
• JSAUX USB C — biggest trade-off: it is an adapter, not headphones. You need your own 3.5mm wired earphones, it doesn't do data transfer, and compatibility has real gaps (some OnePlus models, OMTP mic-only gear, Apple EarPods volume control).
• DCBCODGAL Earbuds — biggest strength: genuinely wireless in-ear buds with Bluetooth 5.3, a dual LED battery display, and a USB-C charging case that tops the buds up in about 1.5 hours for long total playtime.
• DCBCODGAL Earbuds — biggest trade-off: no wired option at all, no active noise cancellation, and everything depends on a Bluetooth link with a roughly 10-meter range.
• Who each pick is for: JSAUX USB C is for people who already own good wired headphones and want to charge while they listen. DCBCODGAL Earbuds are for people who want no cables in daily use and a case they charge over USB-C.
The JSAUX USB C adapter solves one very specific, very annoying problem: modern phones dropped the headphone jack, but you still want to use a wired set of earphones, and your battery is dying at the same time. This little grey dongle splits one USB-C port into two — a USB-C port for power and a 3.5mm female jack for audio. Plug a PD wall charger into the USB-C side and it passes through up to 60W of PD 3.0/2.0 charging while your music or game audio keeps playing. That's the whole point of the product, and it does that job without needing drivers or an app.
The audio side is handled by a Smart DAC chip, which the spec sheet says keeps the transmission stable and free of current noise. The 3.5mm port follows the CTIA standard, so in-line controls and mic-equipped headsets of that type work. Build-wise, JSAUX describes a strong military-fiber cable with strain relief rated for 15,000+ bends, aluminum alloy housing, and metal-coated connectors for a solid contact. At roughly 18–20cm it's short enough to dangle from your pocket without tangling, and light enough to forget about.
Who should buy it: anyone with a USB-C phone or tablet — the compatibility list covers iPhone 15/16 families, most recent Galaxy S and Note models, iPad Pro and iPad mini 6, MacBook, and a long list of Pixel and Huawei devices — who wants to keep using wired headphones without killing their battery. Who should skip it: owners of phones that still have a 3.5mm port (the adapter isn't for you), anyone on the OnePlus models it doesn't support, people who need OMTP or mic-only devices, and anyone expecting to move files through it — there's no data transfer here. Also note the Apple EarPods volume buttons won't work through it.
The DCBCODGAL Earbuds are the opposite approach: cut the cable entirely. These are in-ear true wireless buds running Bluetooth 5.3, with the fast-pairing convenience that comes with it — once you've paired them the first time, they reconnect automatically when you open the charging case. No plugging, no dongle, no adapter to lose in a bag.
Battery is the headline here. A single charge gives up to 8 hours of playtime, and the case extends total listening to roughly 40–46 hours depending on how you count it. The dual LED display on the case shows remaining battery in real time, which is a small feature that genuinely removes the "are these dead?" guesswork. When the case itself runs low, USB-C fast charging refills it in about 1.5 hours. The spec sheet lists a 2-hour battery charge time for the buds as well, so either way you're not waiting around all afternoon.
Comfort and durability are pitched at everyday use: high-quality silicone tips that the brand says were wear-tested for a snug fit, a compact rounded case with a reset button (hold 5 seconds with the buds inside to clear glitchy pairing data), and IPX7 waterproofing for rain and sweat. Sound comes from 13mm dynamic drivers with a titanium-plated diaphragm for deeper bass and cleaner treble, and the buds support both mono and twin stereo modes so you can hand one to a friend.
Who should buy it: commuters, gym-goers, and anyone who wants wireless audio with a long runtime and a case that charges over the same USB-C cable as everything else. Who should skip it: audiophiles who need a wired, latency-free connection; anyone who wants active noise cancellation, because this model has none; and people who prefer over-ear designs — these are strictly in-ear.
• Best for charging while listening → JSAUX USB C. It's the only one of the two that lets you plug in power and audio at the same time, up to 60W PD.
• Best for battery life and untethered use → DCBCODGAL Earbuds. Up to 8 hours per charge and roughly 40–46 hours with the case.
• Best for people who already own wired headphones → JSAUX USB C. It turns your existing 3.5mm gear into something your USB-C phone can use.
• Best for workouts and rain → DCBCODGAL Earbuds. IPX7 waterproofing and no cable to snag.
• Best for call clarity on the move → DCBCODGAL Earbuds. Mono and twin stereo modes plus a mic built into the buds; the JSAUX only passes through audio from whatever headset you attach.
• Best for pocket-sized simplicity → JSAUX USB C. An 18cm dongle with plug-and-play operation and no pairing at all.
• Best for sharing audio → DCBCODGAL Earbuds. Hand one bud to a friend in mono mode; the JSAUX can't do that.
• Best if you hate charging another device → JSAUX USB C. It draws power from your phone's charger rather than needing its own battery.
In my opinion, these two aren't really rivals — they solve different problems, and the right pick depends on whether you're married to wired sound. If you own a good pair of 3.5mm headphones and your main frustration is choosing between charging and listening, I'd buy the JSAUX USB C adapter. It's the cleaner fix for that exact scenario. If you'd rather ditch cables altogether and want a case with a visible battery readout and USB-C fast charging, I'd go with the DCBCODGAL Earbuds. For pure everyday wireless convenience, that's my pick.
Two things matter: the charger and the port. With the DCBCODGAL Earbuds, the USB-C fast charging case reaches full in about 1.5 hours, so use a USB-C cable and a capable wall adapter rather than a weak USB port. With the JSAUX USB C adapter, use a PD wall charger — the spec sheet notes PD gives faster results than other protocols on some newer phones.
The data sheets don't indicate any harm. The JSAUX adapter is rated for PD 3.0/2.0 up to 60W, and the DCBCODGAL case is designed around USB-C fast charging with a stated 1.5-hour full charge. Both are built to handle the charging they advertise.
For the DCBCODGAL Earbuds, drop the buds in the case, close it, and plug the case in over USB-C. For the JSAUX USB C setup, the headphones themselves don't charge — the adapter passes power to your phone, and your wired earphones draw nothing.
Yes. It's an adapter, not a headset — you supply your own 3.5mm CTIA headphones or earbuds. Just avoid OMTP mic-only devices, and note that Apple EarPods volume controls won't work through it.
