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 you already own with a modern iPhone or iPad, choose UGREEN Headphone Adapter; if you need a complete, ready-to-use pair of wired earbuds with a built-in mic and volume remote, choose SUPVOL iPhone.
These two products get lumped together in search results because both are "wired audio for iPhone" gadgets, but they solve completely different problems. One is a converter that lets you keep your favorite cans and your car's aux cable alive. The other is a finished pair of budget earbuds with a cable, a remote and a microphone. Below I break down exactly where each one wins, where each one stumbles, and which one fits your situation.
• UGREEN Headphone Adapter — biggest strength: Apple MFi certified Lightning-to-3.5mm conversion with 48 kHz / 24-bit audio output, noise reduction and a braided, aluminum-shell build rated for a long bending lifespan. It turns the port you already have into the headphone jack Apple removed.
• UGREEN Headphone Adapter — biggest trade-off: It is a dongle, not headphones. You must already own 3.5mm headphones, and it does not work with USB-C iPads or the iPad mini 6.
• SUPVOL iPhone — biggest strength: A complete 2-pack of in-ear wired earbuds with an inline mic, volume remote and 20 Hz–20,000 Hz dynamic drivers — nothing else to buy, and a spare set in the box.
• SUPVOL iPhone — biggest trade-off: The setup is unusually fiddly. You must enable Bluetooth before plugging in, wait for a pop-up window, and if it does not appear, manually connect to a device named "Beats" in your Bluetooth list.
• Pick UGREEN Headphone Adapter if you already love a specific pair of over-ear or in-ear 3.5mm headphones and want to keep using them on a Lightning iPhone.
• Pick SUPVOL iPhone if you just want working earbuds for calls and music today, with a second pair as backup.
Think of this as a translator. Your iPhone speaks Lightning; your headphones speak 3.5mm. The UGREEN adapter sits in between and does the interpreting, and it does it with an Apple MFi certification rather than a generic chip. In practice that matters, because the certification is the difference between a clean handshake with iOS and the "this accessory is not supported" message that plagues cheap dongles. The adapter also supports in-line control, so the volume and call buttons on your existing headphone cable keep working, and it is plug-and-play with no settings to toggle.
Who should buy it? Anyone with a Lightning iPhone — the compatibility list runs from the iPhone 14 Pro Max and 14 Plus back through the 13, 12, 11, XS, XR, X, 8, 7 and SE 2020 — who wants to keep using wired headphones, plug into a car's aux input, or connect to a speaker or amp. The 3.94-inch length and 21-gram weight make it a pocketable little cable rather than a bulky brick. Who should skip it? If you do not already own 3.5mm headphones, this purchase makes no sense on its own — you would be buying an adapter for gear you do not have. It is also the wrong tool if you own an iPad mini 6 or a USB-C iPad Pro, since those ports are not Lightning. And honestly, if what you want is a brand-new pair of earbuds, this is not that product.
SUPVOL iPhone: Who It's For
This is the opposite approach: instead of adapting what you own, SUPVOL hands you the whole chain — drivers, cable, remote and microphone — in one box, and throws in a second set. The earbuds are in-ear with rounded tips and a plastic housing in white, using dynamic drivers covering a 20 Hz to 20,000 Hz frequency range. That is the standard full-range span, and SUPVOL describes the tuning as bass-forward with a tight midrange and precise treble. For podcasts, calls and commuting playlists, that profile is exactly what most people want.
The feature that will matter most day to day is the inline remote. It controls volume, playback and call answering, so you are not pulling your phone out on a busy street or in a meeting. The built-in microphone is the reason to consider these over a plain pair of throwaway earbuds — it turns them into a legitimate headset for work calls and voice notes, and the in-ear seal helps block background noise for clearer pickup on the other end.
Who should buy it? Someone who needs working earbuds for calls and music right now, wants a mic and volume control, and likes having a spare pair. Who should skip it? Anyone who already owns great headphones and just needs to connect them — that is UGREEN's job — or anyone who wants zero-configuration, plug-and-play simplicity.
Side-by-Side: Which Should You Choose?
• Best for keeping your existing headphones → UGREEN Headphone Adapter. It converts Lightning to 3.5mm and preserves your own headphones' sound.
• Best for a complete out-of-the-box solution → SUPVOL iPhone. Drivers, cable, mic and remote included, times two.
• Best for calls and voice chat → SUPVOL iPhone. The inline microphone and remote are built for answering and ending calls.
• Best for audio fidelity with your own gear → UGREEN Headphone Adapter. 48 kHz / 24-bit output with noise reduction beats what a budget earbud set is designed to do.
• Best for car aux and speaker connections → UGREEN Headphone Adapter. Plug it into a 3.5mm aux cable and your Lightning phone feeds the stereo.
• Best for durability under daily pocket abuse → UGREEN Headphone Adapter. Aluminum shell, braided nylon and a 15,000-plus bend rating.
• Best for hassle-free setup → UGREEN Headphone Adapter. Plug and play, no Bluetooth dance required.
• Best for a spare set you can leave in a bag → SUPVOL iPhone. Two pairs per pack means one for home, one for travel.
If I were buying for myself, I would pick the UGREEN Headphone Adapter. In my opinion, adapters live or die on reliability, and the combination of Apple MFi certification, 48 kHz / 24-bit output and a braided aluminum build rated for 15,000-plus bends is the more convincing package for someone who already owns headphones worth keeping. The SUPVOL set is a reasonable buy if you genuinely need new earbuds and a microphone, and the two-pack softens the risk — but the Bluetooth-first setup routine is a friction point I would rather not deal with. Check the current price on Amazon before you commit, since that is the one variable that can flip this call.
Yes. UGREEN states the adapter is Apple MFi certified, which is what lets it connect securely to Lightning iPhones without the unsupported-accessory error. It supports in-line control and plug-and-play use with no settings changes.
Yes. SUPVOL lists compatibility with iPhone 14, 14 Pro, 14 Pro Max, 14 Plus, the 13 and 12 series, SE, 11 series, XS Max, X, XR, 8, 8 Plus, 7 Plus and 7, plus iPad and iPod. Just remember to turn Bluetooth on before plugging them in.
They are built for different jobs. The UGREEN adapter passes through your own headphones' audio at up to 48 kHz / 24-bit with noise reduction, so quality depends on the headphones you attach. The SUPVOL earbuds use dynamic drivers covering 20 Hz–20,000 Hz with a bass-forward tuning — fine for calls and casual listening, but limited by the earbuds themselves.
No. The UGREEN adapter is a pure wired Lightning-to-3.5mm connection with no Bluetooth involved. Only the SUPVOL earbuds require you to enable Bluetooth and connect before use.
