If you want a single plug-and-play wired USB-C earbud that just works with modern phones, tablets and laptops, choose AIAUXAI USB C Earbuds; if you need to keep a 3.5mm headphone you already own alive while charging your phone at the same time, choose MTAKYI 2-in-2.
• AIAUXAI USB C Earbuds — biggest strength: a complete, self-contained wired listening solution with a USB-C plug, an in-line remote and a DAC chip built in, so there is nothing else to buy or configure.
• AIAUXAI USB C Earbuds — biggest trade-off: it is a wired in-ear set only, so if your phone still uses Lightning or you want to charge and listen simultaneously, it is not the right tool.
• MTAKYI 2-in-2 — biggest strength: it turns one port into two — a 3.5mm audio jack plus a magnetic charging path — and its Lightning side keeps older iPhones in the game.
• MTAKYI 2-in-2 — biggest trade-off: it is an adapter, not headphones. You must already own a 3.5mm headset, and it does nothing for USB-C-only earbuds or for phones with neither Lightning nor USB-C audio support.
• Who each pick is for: pick AIAUXAI if you want to plug in and listen with zero extra parts; pick MTAKYI if you want to reuse a favourite 3.5mm headset and charge while you listen.
The AIAUXAI USB C Earbuds are a straightforward idea done properly: a wired in-ear headphone with a USB Type-C plug on the end. There is no pairing, no battery to think about, no adapter to lose. You plug into a USB-C audio jack and you are listening. The set ships with a carrying case and two pairs of eartips, which matters more than it sounds — the fit is what keeps an in-ear design comfortable for a long call or a long commute, and having a spare pair of tips to swap is a genuinely useful inclusion.
Where this set earns its place is in the spec list. It uses a dynamic driver with a 20Hz–20,000Hz frequency range and 105dB sensitivity, which is the full audible band and a sensitivity figure that means a phone does not have to strain to drive it loudly. A DAC digital decoder chip sits inside, handling the digital-to-analog conversion so the signal arriving at the driver is clean. The enclosure is plastic with a pink finish and a black case, and the isolation is passive — sound isolation, not active noise cancellation — so it cuts some surrounding noise by sealing your ear rather than by electronics.
The control story is also complete. There is a button remote on the wire for volume up and down, track forward and back, play and pause, and answering, ending or rejecting calls. In my opinion that is the single most underrated feature on a wired headset: you never have to take your phone out of your pocket to skip a song or take a call.
MTAKYI 2-in-2: Who It's For
The MTAKYI 2-in-2 solves a completely different problem. It is an adapter, not a headphone. You get a splitter with a Lightning connector and a USB-C connector on one side, and on the other a 3.5mm audio jack plus a Type-C magnetic charging path. The core promise is simple and specific: listen through your own 3.5mm headphones while charging your phone at the same time. If you have ever been on a long call, a flight or a gaming session with a dead battery creeping up, you know exactly why that matters.
The magnetic design is the feature that separates it from a generic dongle. The two halves hold together magnetically when you are not using them, which keeps the cable from becoming a tangled mess in a bag, and they pull apart cleanly when you need to separate them. Small detail, real-world benefit.
Compatibility is split by connector, and that split is worth reading carefully. The Lightning end covers iPhone 14, 13, 12 and 11 families. The USB-C end covers iPhone 16 and 15 families, Samsung Galaxy S24 down through the S21 range and the Note line, Pixel 4, Huawei and OnePlus. The Lightning side carries an Apple MFi certified chip, which is the part that matters most for iPhone owners: it means the adapter is built to work without the "this accessory is not supported" pop-up that plagues cheap dongles.
On the audio side, MTAKYI uses a built-in DAC chip rated up to 48kHz and 24-bit output, with noise reduction technology for a stable transmission without current noise. The build is a silver aluminium alloy shell — heat and corrosion resistant — with shock-absorbing strain relief, and the company states the connector has been through 20,000-plus bending tests and the USB-C side through 15,000 bending cycles. That is durability engineering aimed squarely at the weakest point of any adapter: the joint where the plug meets the cable.
Who should buy it? iPhone owners on Lightning who refuse to give up their wired 3.5mm headset, anyone who needs to charge and listen at once, and people who want one adapter that covers both an older Lightning phone and a newer USB-C one. Who should skip it? If you do not own a 3.5mm headset, or your phone has neither a Lightning nor a USB-C port, or you want earbuds included, this is not the purchase.
• Best for a complete out-of-the-box solution → AIAUXAI USB C Earbuds. Earbuds, case, spare tips and an in-line remote are all in the box; nothing else to buy.
• Best for reusing headphones you already own → MTAKYI 2-in-2. It is the bridge between a 3.5mm headset and a modern port.
• Best for charging while listening → MTAKYI 2-in-2. That dual function is its entire reason to exist; AIAUXAI has no charging path at all.
• Best for sound-isolating in-ear fit → AIAUXAI USB C Earbuds. A sealed in-ear design with two pairs of tips gives you a fit you can adjust; the MTAKYI adapter depends entirely on the headset you plug into it.
• Best for older iPhones (Lightning) → MTAKYI 2-in-2. The Lightning connector and MFi certified chip cover iPhone 11 through 14 families.
• Best for newer USB-C phones, tablets and laptops → AIAUXAI USB C Earbuds. Its compatibility list runs from iPhone 15/16/17 to Galaxy S26, Pixel, OnePlus, iPad, MacBook and Chromebook.
• Best for on-wire call and volume control without touching your phone → AIAUXAI USB C Earbuds. The remote handles volume, tracks, play/pause and calls directly.
• Best for durability engineering at the connector → MTAKYI 2-in-2. Aluminium alloy shell, strain relief and stated bending-test figures target the failure point of an adapter.
My Verdict
Yes, for USB-C models. The compatibility list covers iPhone 15, 16 and 17 families including Pro, Pro Max and the e-series, and it also lists iPad, MacBook, Galaxy, Pixel, OnePlus and various laptops with a USB-C audio jack. It will not work on Lightning-only iPhones.
Yes. That is the point of the splitter — one side feeds a 3.5mm headphone, the other provides a Type-C magnetic charging path. Note that it needs your own 3.5mm headset to produce sound; no earbuds are included.
They are not directly comparable. AIAUXAI is a complete dynamic-driver in-ear set with a DAC chip, 20Hz–20,000Hz response and 105dB sensitivity. MTAKYI is an adapter with a DAC rated to 48kHz/24-bit and noise reduction — how it sounds depends on the headphone you attach. In my opinion, for a self-contained result the AIAUXAI is the safer choice.
Look at what you already own and what you actually need. If you need earbuds plus controls plus a case, AIAUXAI is one purchase. If you need to keep a 3.5mm headset and charge simultaneously, MTAKYI is the only one of the two that does it. Check the current price on Amazon for each, since I do not quote prices here.
