How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a cable that turns an older Lightning iPhone into a wired listening device for a car stereo, speaker or pair of headphones, choose Seulliya Aux Cord; if you need actual earbuds that plug straight into a USB-C iPhone, choose ASKUBSKU USB C Earbuds.
• Seulliya Aux Cord — biggest strength: Apple MFi certified chip with a built-in DAC, so a Lightning iPhone can feed a 3.5mm AUX input without "accessory not supported" errors.
• Seulliya Aux Cord — biggest trade-off: It's a cable, not headphones. You still need a car stereo, speaker or headphone with a 3.5mm jack, and it does not work with USB-C or Micro-USB devices.
• ASKUBSKU USB C Earbuds — biggest strength: Everything is in one package — USB-C plug, in-ear buds, inline mic, remote volume control and a carry bag.
• ASKUBSKU USB C Earbuds — biggest trade-off: They only fit USB-C ports, so Lightning iPhones are out, and the in-ear fit won't suit everyone.
• Who the Seulliya is for: iPhone 14/13/12/11/XS/XR/X/8/7 owners who want to keep using the AUX input in their car or their favourite wired headphones.
• Who the ASKUBSKU is for: iPhone 17 Air/16/15 owners, iPad and Samsung/Pixel USB-C users who want a wired earbud with a mic for calls and music.
The Seulliya Aux Cord is a one-job tool, and it does that job in a very specific direction: from a Lightning port out to a 3.5mm jack. If your iPhone still uses Lightning and your car, home stereo, speaker or headphones still use an AUX input, this is the bridge between two generations of hardware that otherwise refuse to talk to each other. The MFi certified chip is the part that matters most here — it's the reason you don't get the dreaded "accessory not supported" pop-up that plagues cheap uncertified Lightning adapters.
Inside, Seulliya uses a DAC (digital-to-analog converter) paired with high-purity copper wiring, and the listing states support for up to 24bit/96kHz digital audio with a 96 KHz frequency figure. In plain terms, that's more headroom than a car stereo or a set of everyday earbuds will ever expose. The design details are modest but sensible: 3.3 ft of soft TPE, roughly 9 grams, white, abrasion-resistant, and rated for a 15,000+ bend lifespan. TPE is the flexible, rubbery jacket material that resists the kinking and knotting that kills cheap cables.
Who should buy it? Anyone with a Lightning iPhone who refuses to give up the AUX jack — the commuter plugging into a car stereo for music and navigation, the person with a beloved pair of wired headphones, the household with an older speaker dock. Who should skip it? Anyone with a USB-C iPhone or Android phone, since Seulliya explicitly warns it works only with Lightning devices. And if you want earbuds, not a cable, this isn't the product — it's the middleman.
The ASKUBSKU USB C Earbuds are the opposite approach: instead of an adapter that lets you keep old gear, they're a complete listening solution for the newer port. The plug is USB-C, which covers iPhone 17 Air/16/15 Pro Max Plus, iPad, Samsung S26 down through S23 FE, S22, A35 and Flip models, and Pixel 10/9/8. Wired means no charging, no pairing, no battery to run down mid-commute.
The feature set is aimed squarely at daily practicality. There's a built-in microphone, and ASKUBSKU describes it as having no noise interference during calls. The inline remote handles volume, play/pause, skipping tracks and picking up or hanging up calls — the kind of thing you only appreciate once you've fumbled for your phone on a crowded bus. Sound isolation is listed as the noise control method, which is passive blocking rather than active cancellation; the rounded-tip dynamic drivers cover a 20 Hz – 20,000 Hz range, the standard full-range span.
The ergonomics are the selling point ASKUBSKU leans on hardest: a 45° in-ear angle designed to reduce the pain and fatigue that comes with long wear. They're plastic-bodied, silver, lightweight, and ship with a black or gray carry bag. Who should buy them? USB-C phone owners who want cheap, simple, tangle-resistant wired audio for calls, podcasts and music on the move. Who should skip them? Lightning iPhone users, anyone who dislikes in-ear tips, and anyone hoping for active noise cancellation — this is isolation, not ANC.
• Best for older Lightning iPhones → Seulliya Aux Cord, which is built specifically for iPhone 14/13/12/11/XS/XR/X/8/7 and iPod touch/iPad.
• Best for USB-C phones → ASKUBSKU USB C Earbuds, covering iPhone 17 Air/16/15, iPad, Samsung and Pixel USB-C devices.
• Best for car stereo and navigation audio → Seulliya Aux Cord. Plug the Lightning end into the phone, the 3.5mm end into the car's AUX input, done.
• Best for calls and hands-free control → ASKUBSKU USB C Earbuds, thanks to the built-in mic and inline remote for volume and track skipping.
• Best for portable everyday listening → ASKUBSKU USB C Earbuds — in-ear, lightweight, with a carry bag for pockets and bags.
• Best for durability against bending → Seulliya Aux Cord, rated for a 15,000+ bend lifespan with a soft TPE jacket.
• Best for reusing headphones or speakers you already own → Seulliya Aux Cord. It doesn't replace your gear; it reconnects it.
• Best if you want nothing extra to carry → ASKUBSKU USB C Earbuds. One cable, two buds, no separate headphones required.
In my opinion, the right pick comes down to one question: which port is on your phone? If you're on a Lightning iPhone and you want your car stereo, speaker or wired headphones back in the loop, I'd buy the Seulliya Aux Cord — the MFi certification and DAC are exactly what that job needs, and the 3.3 ft TPE build is the right kind of boring. If you're on a USB-C iPhone, iPad or Android phone and you want earbuds with a mic and controls, I'd buy the ASKUBSKU USB C Earbuds. Neither is a compromise pick; they simply serve different ports and different jobs.
FAQ
how to use headphones for iphone
how to use wired headphones for iphone 15
The iPhone 15 family uses USB-C, so a Lightning-to-3.5mm cable like the Seulliya won't fit. You want USB-C audio gear instead, such as the ASKUBSKU USB C Earbuds, which plug straight in and give you inline volume, track control and a mic.
how to use wired headphones for iphone
Check the port first — that's the whole decision. Lightning iPhones pair with the Seulliya Aux Cord; USB-C iPhones pair with USB-C earbuds like the ASKUBSKU. Seulliya itself warns the cable is Lightning-only and won't work with USB-C or Micro-USB jacks.
how to use wired headphones for iphone 16
The iPhone 16 is a USB-C device, so the ASKUBSKU USB C Earbuds are the direct match — plug in and listen, with no driver or external power required on the Seulliya side of things either. Skip any Lightning cable for this phone, because the connector simply won't seat.
