• Matsusho Apple MFi Certified — biggest strength: up to PD 60W fast charging with simultaneous USB-C audio, plus an MFi certified decoder chip and 24bit/48kHz lossless output. It ships as a 2-pack.
• Matsusho Apple MFi Certified — biggest trade-off: it splits USB-C into two USB-C ports, so it only helps you if your headphones already end in USB-C. There is no 3.5mm jack here.
• YINYOO USB C Splitter — biggest strength: it splits one USB-C port into a 3.5mm headphone jack and a PD charging port, so ordinary wired headphones work while you charge, with a DAC chip handling the conversion.
• YINYOO USB C Splitter — biggest trade-off: charging tops out at 15W (5V/3A), which is a much lower ceiling than the Matsusho, and the brand notes a very brief audio dropout when power is connected or disconnected.
• Who each pick is for: Matsusho for USB-C headphone owners who care most about fast charging; YINYOO for 3.5mm headphone and IEM owners who want a small, tough dongle.
The Matsusho adapter is a 2-in-1 USB-C to dual USB-C splitter. In plain terms: it takes the single port on your phone and turns it into two USB-C ports. One is for your USB-C headphones or earbuds, the other is for your charging cable. That sounds simple, but it is exactly the setup a lot of newer phone owners are missing, because the headphone jack disappeared and the charging port is now the only wired audio path left.
Where this adapter separates itself is the charging side. Matsusho rates it at up to PD 60W, and the brand claims that is roughly 3X faster than an original lightning-port splitter. The adapter also uses an intelligent chip to manage that power and, per the description, to avoid overheating during rapid charging. For headphones specifically, this matters more than people expect. If you are running power-hungry over-ear USB-C headphones with active noise cancellation or a built-in amp, they pull current from the phone. Charging at 60W while audio plays keeps the battery moving in the right direction instead of slowly draining. Matsusho does note that for some newer phones the adapter may not support QC, and it recommends a PD wall charger for the fastest results — a fair caveat rather than a hidden one.
Audio quality is handled by an MFi certified chip with a decoder built in, and Matsusho lists support for up to 24bit/48kHz lossless output. There is also noise reduction in the design, with the aim of a clean, buzz-free signal. MFi certification is the part I would weigh heavily if you are on an iPhone: it means the dongle is built to the Apple accessory standard, and the decoder chip means you should not have to worry about a system update breaking audio.
Compatibility is broad — iPhone 17, 17 Pro, 17 Pro Max, Air, 16, 16 Plus, 16 Pro, 16 Pro Max, 15, 15 Plus, 15 Pro, 15 Pro Max, iPad Pro, iPad Mini 6, iPad Air 4/5, Galaxy S25 through S20 series, Note 20/10, and Pixel 9 down to Pixel 2 XL. It comes as a 2-pack, which is genuinely useful if you want one in a bag and one at a desk.
Who should buy it: anyone with USB-C headphones who wants to charge fast and keep listening. Who should skip it: anyone whose headphones end in a 3.5mm plug. This adapter will not help you.
The YINYOO USB C Splitter, sold under the CCZ CA01 model name, does a different job. It splits one USB-C port into two outputs: a PD-compatible charging port and a 3.5mm headphone jack. That 3.5mm jack is the whole point. Most wired headphones and in-ear monitors in the world still use it, and this dongle is how you keep using them on a phone that only has USB-C.
Because the phone has no analog jack, the adapter has to convert digital audio to analog itself, and YINYOO uses a DAC smart chip to do it. The brand claims higher-fidelity stereo audio and stable transmission with noise reduction built in. This is the correct architecture for driving wired IEMs, and it is the reason this adapter is marketed specifically toward KZ ZS10 PRO and similar in-ear monitor owners. One honest note from the brand: connecting or disconnecting power causes a very brief loss of music sound. That is a real quirk, and if you are mid-game or mid-call it is worth knowing about in advance.
Charging is rated at up to 15W (5V/3A) PD, and YINYOO says it will not reduce your device's original charging speed, with compliance across PD, QC, and PPS standards. That is a sensible, conservative figure. It is not a fast-charge monster, but it is enough to hold steady or slowly climb while you listen — which is the realistic goal when you are gaming or on a long commute.
Build quality is where the YINYOO punches above its size. The shell is aluminum and the cord is nylon braided, which is a meaningfully sturdier combination than a bare plastic dongle. It is compact and light, plug and play, and the brand positions it for travel, workouts, commutes, and car use. Compatibility covers iPhone 16/15 series, Galaxy S24 down through S8 Plus, Note 20 through Note 8, iPad Pro, iPad Mini 6, MacBook, Pixel 9 through 6, and Huawei Mate and P-series devices.
Who should buy it: anyone with 3.5mm headphones or IEMs who wants to charge and listen at once, and anyone who wants a small adapter that survives being tossed in a pocket. Who should skip it: anyone chasing maximum charging wattage, or anyone whose headphones are USB-C — you would be paying for a jack you cannot use.
Side-by-Side: Which Should You Choose?
• Best for 3.5mm wired headphones and IEMs → YINYOO USB C Splitter. It is the only one of the two with an actual headphone jack.
• Best for USB-C headphone owners → Matsusho Apple MFi Certified. Dual USB-C output is exactly what modern USB-C earphones and ANC over-ears need.
• Best for iPhone users who want certification → Matsusho Apple MFi Certified. MFi certification plus a decoder chip is the more reassuring combination for iOS.
• Best for durability in a bag or pocket → YINYOO USB C Splitter. Aluminum shell and nylon braided cord are sturdier by design than a plain adapter body.
• Best for long gaming or streaming sessions → Matsusho Apple MFi Certified. Higher charging headroom means less risk of the battery sliding downhill mid-session.
• Best for travel and commutes → YINYOO USB C Splitter. Compact, lightweight, and built for pocket carry.
• Best for getting two units → Matsusho Apple MFi Certified. It ships as a 2-pack, so you can leave one in each place you listen.
In my opinion, the deciding question is not which adapter is better — it is what your headphones plug into. If you own USB-C headphones and you want the fastest charging while audio plays, I would buy the Matsusho Apple MFi Certified. The PD 60W rating, MFi certified chip, and 24bit/48kHz output make it the stronger pick for fast-charge headphone use, and the 2-pack adds real convenience. If your headphones end in 3.5mm, none of that matters, and I would buy the YINYOO USB C Splitter instead — it is the only one that gives you a jack, and its aluminum-and-braided build makes it the better pocket companion. Check the current price on Amazon for both before you commit; the numbers move, and your headphone connector does not.
how to fast charge bose headphones
You cannot force faster charging from the adapter alone — the headphones and the wall charger both set the ceiling. What an adapter like the Matsusho does is pass through up to PD 60W so your phone is not starved while the headphones are connected. Pair it with a PD wall charger, which Matsusho explicitly recommends for the fastest results.
how to charge headphones faster
Use a PD charger rather than a basic one, and use an adapter rated for higher wattage. The Matsusho is rated up to PD 60W, while the YINYOO tops out at 15W (5V/3A). Matsusho also notes that some newer phones may not support QC through its adapter, so PD is the safer standard to build around.
how to charge headphones
On a modern phone with one USB-C port, you need a splitter: the adapter occupies the port, your headphone cable goes into the audio side, and your charging cable goes into the power side. The Matsusho feeds both from USB-C ports; the YINYOO feeds one USB-C power port and one 3.5mm jack. Plug and play, no setup either way.
is fast charging bad for headphones
Not inherently, and neither adapter's headphones draw is the risk factor here. The Matsusho description states its intelligent chip avoids overheating during rapid charging, and the YINYOO says its 15W output will not reduce your device's original charging speed. The real caution is matching your wall charger to what your phone supports.
