How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want to keep using the wired headphones, car stereo or home hi-fi you already own with a Lightning iPhone, choose Seulliya MFi Certified iPhone; if you need a pair of USB-C earbuds for an iPhone 15, 16 or 17 (or a modern Android phone) with a built-in remote and mic, choose wamaxlink 2.
• Seulliya MFi Certified iPhone — biggest strength: a 3.3 ft Lightning-to-3.5mm adapter cable with a real MFi-certified chip (Realtek DAC) and 24K gold-plated contacts, so it turns an old 3.5mm device into something your Lightning iPhone can drive.
• Seulliya MFi Certified iPhone — biggest trade-off: it is a passive adapter, not headphones. You still need a 3.5mm device on the other end, and it does not support USB-C iPads/Pros or AirPods Max.
• wamaxlink 2 — biggest strength: you get two complete USB-C in-ear headsets with a mic and a three-button remote, a 36-month warranty and a 4 ft cord, so there is nothing else to buy.
• wamaxlink 2 — biggest trade-off: it only fits USB-C devices, so it is useless on a Lightning iPhone, and its 3.5mm jack listing looks like a spec-sheet inconsistency worth double-checking against your phone's port.
• Pick Seulliya MFi Certified iPhone if your phone still has a Lightning port and you want to reuse existing speakers, stereos or wired cans.
• Pick wamaxlink 2 if you own an iPhone 15/16/17 or a USB-C Android and just want cheap, wired, no-pairing earbuds with call controls.
This is a problem-solver, not a gadget. The Seulliya AUX cord exists because Apple dropped the headphone jack, and plenty of us still own a car stereo, a kitchen speaker, a receiver or a pair of wired headphones that only speak 3.5mm. The cable is 3.3 ft long, black, and ends in a Lightning plug on one side and a standard 1/8-inch male jack on the other. Plug it in and the audio just plays — no driver, no external power, no settings to fiddle with.
The part that matters most is the chip. Seulliya uses an Apple MFi-certified smart chip, and the description names a Realtek DAC supporting up to 24-bit/96kHz digital audio. In plain terms: the iPhone treats it as a legitimate audio accessory, so you get stable, lossless-feeling playback instead of the "this accessory is not supported" nag screen that cheap uncertified adapters are famous for. The contacts are 24K gold-plated, which is the usual way to reduce corrosion and keep the signal clean over time. It also claims a 15,000+ bend lifespan with soft TPE insulation, which is a durability figure worth noting if you tend to shove cables into pockets and gloveboxes.
Who should buy it: anyone with an iPhone 13, 12, 11, XS, XR, X, 8, 7, 6 or SE who wants to keep using an older car head unit, an aux input, a portable speaker or a wired headphone. It also works with Lightning-era iPads and iPods. Who should skip it: if your phone is an iPhone 15 or newer, or any USB-C iPad or iPad Pro, this cable simply will not plug in. Same if you were hoping to use it with AirPods Max, which need bidirectional transmission this adapter does not provide.
The wamaxlink 2 is a completely different animal: it is a two-pack of finished USB-C wired earbuds, not a cable. You get two identical in-ear headsets in bright white ABS plastic, each with a 4 ft cord, a built-in DAC chip, a microphone and an inline remote. The remote gives you the basics — one press for play/pause, two for next track, three for previous track — plus volume and call control. That is the whole appeal: no Bluetooth pairing, no charging case, no battery to babysit.
Compatibility is the headline here. The listing covers iPhone 17, 17 Pro, 17 Pro Max and Air, iPhone 16 and 16 Pro/Pro Max, iPhone 15 and 15 Pro/Pro Max, iPad Pro 12.9/11-inch, iPad Air 4/5, iPad Mini 6, MacBook and MacBook Pro, plus a long list of USB-C Android phones (Galaxy S20 through S26, Pixel 2 through 9 Pro XL and more). The ergonomic in-ear shape is designed to reduce fatigue over long sessions, and there is a magnet on the back of each earbud so they snap together and resist tangling in a bag. The listing also advertises advanced noise reduction and what it calls professional-grade tuning with 360° surround sound — treat that as marketing language, but a wired in-ear seal does genuinely block more outside noise than an open earbud.
Who should buy it: iPhone 15/16/17 owners, USB-C Android users, commuters, students and anyone who wants a spare pair in a backpack or at a desk. The 36-month warranty and 24/7 support claim is unusually long for this category. Who should skip it: Lightning iPhone owners, and anyone who wants over-ear comfort or a detachable cable. One thing to verify before ordering — the spec sheet lists a "3.5 mm Jack" under connectivity even though the entire product is USB-C, which reads like a data-entry error. Check that your phone's port is USB-C, not Lightning.
Side-by-Side: Which Should You Choose?
• Best for reusing old gear → Seulliya MFi Certified iPhone. It converts a Lightning iPhone into something a 3.5mm stereo, speaker or headphone can actually accept.
• Best for iPhone 15/16/17 owners → wamaxlink 2. Seulliya's Lightning connector is a non-starter on those phones.
• Best for iPhone 13 and older → Seulliya MFi Certified iPhone. It is built specifically for that connector and the devices that use it.
• Best for calls and remote control → wamaxlink 2. It has a mic and an inline remote; the Seulliya cable is audio-out only.
• Best for car aux and home hi-fi → Seulliya MFi Certified iPhone. A 3.3 ft cable into an aux-in port is exactly the job it was made for.
• Best for commuting and running → wamaxlink 2. A 4 ft cord, magnetic earbuds and an in-ear seal suit movement better than a loose adapter cable.
• Best for having a backup on hand → wamaxlink 2. The two-pack means one pair can live in a bag and one at home.
• Best for travel-light setup → Seulliya MFi Certified iPhone. One small cable, no earbuds to lose.
If I had to pick one, I would buy the wamaxlink 2 for a modern USB-C iPhone or Android phone — in my opinion it is the more complete purchase, because you get two working headsets, a mic, a remote and a long warranty rather than a single adapter. But that recommendation flips entirely if your phone still has a Lightning port: then the Seulliya MFi Certified iPhone is the right call, and the wamaxlink 2 will not even fit. Match the connector to your phone first, then decide. Whichever you land on, check the current price on Amazon before you commit.
No. It uses a Lightning connector, so it fits iPhone 14 and older, plus Lightning-era iPads and iPods. For an iPhone 15/16/17, you need a USB-C solution like the wamaxlink 2.
Does the wamaxlink 2 work with an iPhone that has a Lightning port?
They do different jobs, so it is not a clean comparison. Seulliya passes digital audio through an MFi-certified chip with gold-plated contacts up to 24-bit/96kHz, but the final sound depends on the speaker or headphones you plug in. wamaxlink 2 is a self-contained in-ear headset with its own DAC and noise reduction.
Value depends on what you already own. If you have a working car stereo or wired headphones, the Seulliya cable revives them for very little. If you need everything, the wamaxlink 2 gives you two headsets plus a 36-month warranty in one purchase. Check the current price on Amazon to compare the two directly.
