How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a single wired USB-C headset that also doubles as your daily driver for a computer, choose APETOO USB C Headphones; if you need a Lightning-to-3.5mm adapter so you can keep using the wired headphones you already own on an older iPhone, choose Seulliya Apple MFi Certified. These two products solve completely different problems, and the right pick depends on which jack your devices actually have — not on which one sounds more impressive in a listing.
• APETOO USB C Headphones — biggest strength: a complete, ready-to-use wired USB-C headset with a digital DAC chip, inline volume/mic controls, a 4FT cable, a carrying case and spare ear tips — one purchase, everything included.
• APETOO USB C Headphones — biggest trade-off: it needs a USB-C port, so Lightning-only iPhones (and anything with a 3.5mm jack) are out unless you adapt.
• Seulliya Apple MFi Certified — biggest strength: certified Lightning-to-3.5mm conversion with a 32-bit RISC-V DAC (95dB SNR, up to 48kHz), so older iPhones keep working with any 3.5mm headphone you already own.
• Seulliya Apple MFi Certified — biggest trade-off: it is an adapter, not a headphone, and it explicitly does not support call or mic functions.
• Who each is for: APETOO for anyone with a USB-C phone, tablet, laptop or Mac who wants one cable to rule them all; Seulliya for Lightning-port iPhone and iPad owners who want to keep their favorite 3.5mm cans alive.
The APETOO set is a wired in-ear headphone built around a USB-C plug and a built-in digital DAC chip. That chip matters more than it sounds: instead of relying on your device to convert audio, the headphone handles the digital-to-analog step itself, which is why APETOO can claim high-fidelity stereo transmission without loss. The 32 ohm dynamic drivers span 20 Hz to 20,000 Hz, and the oval silicone tips are designed to physically block ambient noise rather than cancel it electronically. In practice that means the isolation you get depends on how well the tips seal, which is exactly why APETOO ships two extra sizes (S and L) alongside the installed pair.
Who should skip it? If your phone is a Lightning iPhone 14 or older, this is the wrong connector, full stop. And if you want true active noise cancellation rather than passive tip isolation, this is not that product. The copper-housed, rose-pink in-ears are also a look — if you wanted something visually neutral, that is a personal preference worth weighing.
Seulliya Apple MFi Certified: Who It's For
The Seulliya adapter is a different category entirely. It is a Lightning-to-3.5mm dongle: you plug the Lightning end into an iPhone or iPad, and the 3.5mm end accepts whatever wired headphones, earbuds, car aux cable or speaker you already have. It carries Apple MFi certification, which is the meaningful part — certified chips are what eliminate the "this accessory is not supported" pop-up errors that plague cheap uncertified adapters. The audio path runs through a 32-bit RISC-V DAC clocked at 125MHz with a 95dB signal-to-noise ratio and sampling rates up to 48kHz.
Read the spec sheet carefully, though, because one line changes everything: this adapter is designed for listening and does not support call or mic functions. If you plug a headset with an inline mic into it, you should not expect the mic to work. That makes it a music, podcast and audiobook tool — great for a commute, the gym, a car aux input or a home office where you only need playback. It is not a conferencing solution.
The compatible device list is the Lightning era: iPhone 14 Pro Max down through iPhone 7, plus iPads from the 4th generation through 9th generation, iPad Air 1st through 3rd gen, and iPad mini 1st gen through 5th. The TPE cable is built for bend resistance, and the one-pack format means you get a single adapter — useful to park in a bag or a car, though if you want one for every location you would need more than one. No plug, no battery, no setup: plug and play.
• Best for a USB-C phone, tablet or laptop → APETOO USB C Headphones. iPhone 15–17, iPad, MacBook, Galaxy, Pixel and OnePlus all connect directly.
• Best for a Lightning iPhone or older iPad → Seulliya Apple MFi Certified. It is the only one of the two that physically fits those ports.
• Best for computer use → APETOO USB C Headphones. It is a complete headset with a mic and volume remote, so it handles calls and meetings as well as music on a MacBook or USB-C laptop.
• Best for keeping your existing wired headphones → Seulliya Apple MFi Certified. The adapter exists precisely so you do not have to replace gear you like.
• Best for calls and voice chat → APETOO USB C Headphones. Seulliya's adapter explicitly does not support mic functions.
• Best for passive noise isolation → APETOO USB C Headphones. Silicone tips in three sizes create a physical seal; the adapter offers nothing here.
• Best for pure playback on an old iPhone → Seulliya Apple MFi Certified. A certified DAC with 95dB SNR at up to 48kHz is a clean listening path.
• Best value for a single do-everything purchase → APETOO USB C Headphones. Case, spare tips, mic and controls are all in the box; the adapter is one small part.
In my opinion, the APETOO USB C Headphones are the better buy for most people reading this, because they are a finished product rather than a bridge: they work as headphones for a computer, a USB-C phone and a tablet, and they include the mic, the volume remote, the case and the spare tips you would otherwise buy separately. I would only steer you to the Seulliya adapter if you own a Lightning-port iPhone or older iPad and want to keep using your existing 3.5mm headphones — and even then, only for listening, since the mic does not pass through. Check the current price on Amazon before you commit, since that is the one variable that can flip a close call.
How to use headphones for iphone
It depends on the port. On iPhone 15 and later, plug a USB-C headphone like the APETOO set straight in — no adapter needed. On iPhone 14 and earlier, you need a Lightning-to-3.5mm adapter like the Seulliya unit, then plug any 3.5mm headphone into it.
How to use wired headphones for iphone 15
The iPhone 15 series uses USB-C, so a USB-C headphone connects directly to the charging port. The APETOO headphone is built for exactly this — plug it in and it works, and if the sound routes oddly on a Mac, select "USB" under Sound settings.
How to use wired headphones for iphone 16
Same as the iPhone 15: USB-C is the audio port, so a native USB-C headset plugs in with no adapter. If you own 3.5mm headphones instead, you would need a USB-C-to-3.5mm adapter, which is a different product from the Lightning adapter covered here.
A headphone like the APETOO set contains the drivers, mic and controls, so it plays audio by itself. The Seulliya adapter contains only a DAC and a jack, so it produces no sound on its own — it just lets 3.5mm gear connect to a Lightning port, and it does not carry mic audio.
