How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a dual USB-C splitter that lets you run USB-C headphones, a 60W PD charger and even high-speed data through one small adapter, choose Feipool USB C Splitter; if you need a cheap-to-keep-around 3.5mm headphone-and-charger dongle that works cleanly with iPhone and still fast-charges headphones on a long call center shift, choose 1STCHAMP MFi Certified USB.
• Feipool USB C Splitter — biggest strength: one female USB-C port that doubles as an audio jack and a 10Gbps USB 3.0 Gen 2 data port, plus 60W PD pass-through charging, all in a single 3.94 x 1.57 x 0.79 inch adapter.
• Feipool USB C Splitter — biggest trade-off: it's built for USB-C headphones, not 3.5mm ones, it won't carry video, and it won't drive an external HDD.
• 1STCHAMP MFi Certified USB — biggest strength: a 3.5mm jack plus 60W PD charging with MFi certification, so iPhone users get no pop-up warning, and you get three adapters in one pack.
• 1STCHAMP MFi Certified USB — biggest trade-off: the headphone side is a standard 3.5mm analog jack, so it's useless with USB-C headphones, and the 24bit/48kHz DAC ceiling is fine for calls and streaming but not for high-res audio files.
• Who each pick is for: Feipool for USB-C headphone owners and anyone who wants charging plus fast data on the same adapter; 1STCHAMP for iPhone and 3.5mm headset users who want a spare in every bag.
The Feipool adapter is a 3-in-1 piece: a USB-C headphone port, a 60W PD charging port, and — this is the part most people miss — a female USB-C port rated for USB 3.0 Gen 2 10Gbps data. That means the same port you'd plug a USB-C headset into can also take a USB-C mouse, keyboard, flash drive, card reader or SSD. It also handles ProRes video recording on iPhone 16 Pro and 16 Pro Max. The things it won't do are video output to a display and external hard drives, so don't buy it expecting a dock.
Who should buy it: USB-C headphone owners, iPhone 15/16 users, Galaxy and Pixel users, and anyone who wants charging plus fast file transfer from one port. Who should skip it: anyone with a 3.5mm headset, anyone who needs HDMI or display output, and anyone planning to hang an external hard drive off it. One honest caveat from the spec sheet: it may not negotiate Quick Charge on some newer phones, so Feipool recommends a PD wall charger for the best charging speed.
1STCHAMP MFi Certified USB: Who It's For
The 1STCHAMP adapter takes the opposite approach. Instead of a second USB-C port, it gives you a 3.5mm aux jack plus a PD 60W charging port, and it's MFi certified — meaning iPhone users get full iOS compatibility with no pop-up warning message. That single detail is the reason a lot of people buy it. The built-in DAC is rated at 24bit/48kHz with noise reduction, so you get clean stereo audio without the buzzing that plagues cheap dongles, and the description calls out no-drive plug-and-play with a slim, pocketable ABS body in white.
The 3-pack is the real selling point. Three identical adapters means one stays in the car, one lives in a laptop bag, and one sits on the desk — which is genuinely useful if you're the kind of person who loses dongles. It works across iPhone 17/17 Pro/17 Pro Max/17 Air/16e/16/15 series, iPad Mini 7/6, iPad Pro, iPad Air, iMac, MacBook Pro/Air, Galaxy S25 down to S8 and Note 20/10, Pixel 10 through 6, and most USB-C tablets, phones and laptops. Warranty is listed at 60 months with 24/7 support, resolved within 24 hours per the listing.
Who should buy it: 3.5mm headset users, iPhone owners who want MFi-certified peace of mind, and anyone who wants spares scattered around. Who should skip it: USB-C headphone owners — the jack is analog 3.5mm only — and anyone who needs data transfer or video from the adapter, since neither is offered here. A kids headset for call center setups is a realistic use case too: hand a child a cheap wired 3.5mm headset and it plugs straight in without any driver fuss.
• Best for USB-C headphones → Feipool USB C Splitter. Its headphone port is USB-C, and it doubles as a 10Gbps data port.
• Best for 3.5mm headsets → 1STCHAMP MFi Certified USB. Analog aux jack, no adapter-on-adapter stacking.
• Best for iPhone users worried about compatibility warnings → 1STCHAMP. MFi certification means no pop-up message on iOS.
• Best for charging while listening → a tie. Both run 60W PD pass-through, so both can fast charge headphones and phone at once.
• Best for data and file transfer → Feipool. USB 3.0 Gen 2 at 10Gbps, plus ProRes recording support on iPhone 16 Pro models.
• Best for multiple devices or travel spares → 1STCHAMP. Three adapters in the pack beat one.
• Best for audio spec transparency → 1STCHAMP names its DAC figures (24bit/48kHz); Feipool names the Realtek chip and lossless transmission but no sample rate.
• Best for bone conduction headphones for call center shifts → check which connector your model uses first — USB-C bone conduction pairs with Feipool, 3.5mm pairs with 1STCHAMP.
In my opinion, the Feipool USB C Splitter is the better buy for most people reading this, because it does more with the same 60W PD charging: audio, charging and 10Gbps data through one adapter. If your whole setup is USB-C, that flexibility is worth more than a spare unit. For a call center desk where someone switches between a wired headset, a charger and occasional file transfers, Feipool is the one I'd pick. But if your headset is 3.5mm, or you're on iPhone and want zero compatibility anxiety, the 1STCHAMP 3-pack is the smarter buy — three MFi-certified adapters with a 24bit/48kHz DAC and a 60-month warranty. Check the current price on Amazon before you commit, since both are inexpensive enough that owning one of each is a reasonable hedge.
FAQ
how to fast charge bose headphones
how to charge headphones faster
Use a PD wall charger rather than a standard USB port — that's where the 60W rating on both adapters actually matters. Feipool specifically notes that using a PD wall charger gives optimal charging speed, and warns that Quick Charge may not work on some newer phones. Also unplug anything drawing power from the data port while charging.
how to charge headphones
With either adapter you plug the charger into the PD port and the headphones into the audio port, then both work at once. On Feipool that audio port is USB-C; on 1STCHAMP it's a 3.5mm jack. Both are plug-and-play with no driver installation.
is fast charging bad for headphones
No — the charging port on these adapters charges your phone, not the headphones. 1STCHAMP notes its chip stabilizes charging voltage and current to protect your devices, and Feipool's PD design targets stable, faster charging. What matters for headphone health is using the correct cable and not exceeding the headset's rated input.
