If you want to keep using the wired headphones you already own with a modern iPhone, choose JSAUX Headphone Adapter; if you need a complete set of wired in-ear headphones with a mic and volume control in one package, choose SUPVOL IPhone.
• JSAUX Headphone Adapter — biggest strength: Apple MFi certified Lightning-to-3.5mm conversion, so your existing wired headphones, earbuds and audio cables keep working on Lightning iPhones — volume, track skipping, calls and Siri included.
• JSAUX Headphone Adapter — biggest trade-off: It is only an adapter. There is no cable, no earpieces and no microphone of its own, so it is useless on its own and it does not fit USB-C iPads.
• SUPVOL IPhone — biggest strength: An all-in-one wired in-ear headphone set with a built-in mic, in-line remote and a 4ft tangle-resistant cable — nothing else to buy.
• SUPVOL IPhone — biggest trade-off: It is a specific pair of earphones, so you are locked into one fit, one cable length and one sound signature, and the fit is in-ear only.
• Pick JSAUX if you already love a pair of wired headphones and just need the connection.
• Pick SUPVOL if you want a ready-to-use wired headphone solution in one purchase.
The JSAUX adapter is a small, single-purpose tool: it changes a Lightning port into a 3.5mm port. That sounds minor until you realise what it unlocks. Every 3.5mm device you own — over-ear headphones, studio monitors, earbuds, aux cables in a car — becomes usable again on an iPhone 14, 13, 12, 11, SE, XS, XR, X, 8 or 7. Because it is Apple MFi certified, the connection is designed to be recognised cleanly by iOS with no error pop-ups, and the adapter keeps the full control set working: volume, previous/next track, pause, answering calls and Siri.
Physically, it is built to survive daily life. The strain relief is tested to 15,000+ bends, the housing is aluminium, and the cable is nylon braided, which also helps it resist tangling. On the audio side, JSAUX states a sampling rate up to 48KHz with noise filtering, which is the range the adapter claims for clean, uninterrupted playback. It measures roughly 7 inches long and 0.15 inches thick — long enough to hang naturally out of a pocket, thin enough not to snag. It weighs almost nothing.
SUPVOL IPhone: Who It's For
SUPVOL approaches the same problem from the opposite direction. Instead of adapting the phone, it ships the headphones themselves: wired in-ear earphones with a Lightning connector, a built-in microphone and an in-line remote. The cable runs 4ft and is described as tangle-resistant, with an oxygen-free copper core intended to limit signal loss. The earpieces are shaped to follow the natural curve of the ear, and SUPVOL says they stay put during long wear or exercise. The driver is a dynamic driver, tuned — per SUPVOL — for driving bass, a tight mid and precise treble, with a dual sound-hole design for a wider, more surrounding presentation.
Control is a single push-button remote: one press to play or pause, two to skip forward, three to go back, plus volume adjustment and call handling. Noise control is listed as none, so this is not active noise cancelling — SUPVOL leans on passive in-ear sealing and "enhanced noise reduction" for call clarity instead. The listing also mentions Bluetooth pairing with a pop-up one-tap connection and 2–8 second auto-reconnect, and the connectivity section lists both wired and Bluetooth, so treat the Bluetooth wording as a secondary feature of the product family rather than a replacement for the wired Lightning connection.
Compatibility is broad: iPhone 14/14 Pro/14 Pro Max/14 Plus, 13 series, 12 series, SE, 11 series, XS Max, X, XR, 8/8 Plus, 7 Plus, 7, plus older 6/6s/5c and SE 2020, along with iPad Pro/Air/Mini. It is a one-year warranty item and sold as a single unit.
Who should buy it: someone who wants the whole job done in one purchase — headphones, mic and remote, wired to the Lightning port, no separate dongle to lose. It suits commuters, call-heavy users and anyone who wants a spare set that lives in a bag. Who should skip it: listeners who prefer over-ear headphones, anyone who needs active noise cancelling, and anyone who already owns premium wired headphones — in that case the SUPVOL set is redundant.
• Best for reusing headphones you already own → JSAUX Headphone Adapter. It converts the port instead of replacing your gear.
• Best for a complete out-of-the-box wired setup → SUPVOL IPhone. Headphones, mic and remote are all included.
• Best for call handling and volume on the cord → both, but JSAUX also supports Siri and full volume/skip control through your own headset's remote.
• Best build-durability signals → JSAUX Headphone Adapter, with its 15,000+ bend strain relief, aluminium housing and nylon braid.
• Best for workout and commute use → SUPVOL IPhone, thanks to the in-ear fit and 4ft tangle-resistant cable.
• Best for aux cables, car stereos and audio gear → JSAUX Headphone Adapter, since it accepts any 3.5mm plug.
• Best for older iPhones (6, 6s, 5c, SE 2020) → SUPVOL IPhone, which lists those models; JSAUX starts at iPhone 7.
• Best for USB-C iPads → neither. Both are Lightning-based, and JSAUX specifically excludes the USB-C iPad Pro and 2021 iPad Mini.
In my opinion, the JSAUX Headphone Adapter is the smarter buy for most people, because it solves the actual problem — a missing 3.5mm jack — without forcing you to replace headphones you already like, and its MFi certification, metal housing and braided cable point to a long service life in a pocket or bag. I would only steer you to SUPVOL IPhone if you genuinely want a new pair of wired in-ear headphones with a mic and remote included, or you are on an older iPhone that JSAUX does not list. If price is your deciding factor, check the current price on Amazon for each before you commit.
how to use headphones for iphone
Plug the adapter into the Lightning port, then plug any 3.5mm headphone into the adapter's female jack. With the JSAUX adapter, iOS recognises it as Apple MFi certified, so volume, playback and call controls on your headset keep working. With SUPVOL, you plug the Lightning connector straight into the phone — no adapter needed.
how to use wired headphones for iphone 15
You generally cannot use either of these on an iPhone 15. Both products are built around the Lightning connector, and the iPhone 15 family uses USB-C. JSAUX also explicitly excludes USB-C iPads, so the same limitation applies across that generation.
how to use wired headphones for iphone
Confirm your iPhone is Lightning-based and running iOS 10.3.1 or later, which is JSAUX's stated requirement. Then connect the adapter to the phone and your headphones to the adapter — the adapter keeps volume, previous/next, pause and Siri working as normal. SUPVOL's wired earphones connect directly to the Lightning port instead.
how to use wired headphones for iphone 16
Neither product is the right fit here. The iPhone 16 uses USB-C, and both the JSAUX adapter and the SUPVOL earphones are Lightning-based. JSAUX notes the same incompatibility for USB-C iPad Pro and iPad Mini models, so look for a USB-C audio solution instead.
