• JSAUX Headphone Adapter — biggest strength: Apple MFi certified Lightning-to-3.5mm conversion with full inline control and a strain-relief build rated for 15,000+ bends.
• JSAUX Headphone Adapter — biggest trade-off: It only fits Lightning-port Apple devices (iPhone 7 through iPhone 14 era, plus older iPads), so it is useless on USB-C phones and the newer USB-C iPads.
• Toeasor USB C Solo — biggest strength: A one-piece USB-C-to-3.5mm cable that connects Beats headphones directly to USB-C phones, tablets and laptops with no extra dongle, plus inline mic and volume control.
• Toeasor USB C Solo — biggest trade-off: It is built specifically around Beats-style headphones with a 3.5mm jack port, and it does not add any 3.5mm output to a phone that lacks one.
• Who each pick is for: JSAUX for anyone with a Lightning iPhone who wants to keep using their favorite wired earbuds; Toeasor for Beats owners who want a cleaner wired connection to a USB-C device.
The JSAUX adapter solves one very specific, very common problem: a modern iPhone has no headphone jack, and you still want to plug in a pair of wired earbuds or headphones. It takes the Lightning port and turns it into a 3.5mm female jack. That is the whole job, and it does it with Apple MFi certification, which is the detail I would pay the most attention to here. MFi means the adapter has gone through Apple's own compatibility requirements, so you should not get the dreaded "this accessory is not supported" error that plagues cheap uncertified dongles.
The compatibility list is broad within Apple's Lightning ecosystem: iPhone 14, 13, 12, 11 series, SE, XS, XR, X, 8 and 7 families, plus iPod touch 6th generation and the older iPad Mini, Air and Pro models that still use Lightning. Note the exclusions — the 2018 iPad Pro 11-inch and 12.9-inch, and the 2021 iPad Mini, all use USB-C and will not work. It also needs iOS 10.3.1 or later, which matters mainly if you are dusting off an iPhone 7.
Buy it if you own a Lightning iPhone and want a compact, certified way to keep using wired headphones or earbuds — especially if you care about the inline remote still working. Skip it if you have a USB-C iPhone, a USB-C iPad, or you are trying to connect Beats headphones that use a detachable 3.5mm cable, because that is a different problem with a different solution.
Toeasor USB C Solo: Who It's For
The Toeasor USB C Solo is not an adapter in the traditional sense — it is a replacement audio cable. One end is USB-C, the other is a 3.5mm male plug, and it is designed to slot into Beats headphones that accept a 3.5mm jack: Solo 4, Solo 3, Solo Pro, Solo HD, Solo2, Studio Pro, Studio 3, Studio 2, Detox, Wireless, Mixr, Executive, Pro and Pill models, among other headphones with a 3.5mm port. The point is to eliminate the dongle dance entirely. Instead of plugging a 3.5mm cable into a Lightning-to-3.5mm adapter and then into your phone, you run one cable from your headphones straight into a USB-C device.
That "built-in connector" approach is the smartest thing about this product. It works with iPhone 17/16/15 and other USB-C smartphones, tablets, laptops and gaming consoles. For anyone who has upgraded to a USB-C iPhone and owns a pair of Beats, this is the cleaner path — fewer connections, fewer points of failure, nothing to lose in a bag.
The cable itself is spec'd reasonably: oxygen-free copper conductors, a 24K gold-plated straight connector for corrosion resistance, TPE jacket material and a 10,000-bend durability rating with a tangle-free design. It is also an all-in-one control cable — there is a built-in microphone, volume buttons and a multi-function button for play/pause and answering or ending calls. The description also frames it as a way to switch to wired listening to conserve your headphone's battery and get zero-latency audio, which is a genuinely useful angle for gaming or watching video.
Buy it if you own Beats (or another 3.5mm-jack headphone) and you are connecting to a USB-C phone, tablet or laptop — and you want mic and volume control on the cable itself. Skip it if your phone still uses Lightning, if your headphones do not have a detachable 3.5mm cable, or if what you actually need is a 3.5mm output for regular wired earbuds.
• Best for Lightning iPhones → JSAUX Headphone Adapter. It is the only one of the two that works with a Lightning port at all.
• Best for USB-C phones and laptops → Toeasor USB C Solo. Built-in USB-C means no separate adapter needed.
• Best for Beats owners → Toeasor USB C Solo. The fit list is written around Beats models with a 3.5mm jack.
• Best for keeping your existing wired earbuds → JSAUX Headphone Adapter. Any 3.5mm earphone, headphone or aux cable plugs into its female jack.
• Best for inline mic and call control → Toeasor USB C Solo. It has a built-in mic plus volume and multi-function buttons on the cable.
• Best for pocket-friendly, leave-it-plugged-in use → JSAUX Headphone Adapter. At 7 inches long it is essentially a dongle that stays on the end of your cable.
• Best for durability claims → a tie, on paper. JSAUX cites 15,000+ bends; Toeasor cites 10,000 bends. Both use braided or TPE jacketing and strain relief, so neither looks fragile.
• Best for audio spec detail → JSAUX Headphone Adapter. It is the only one that states a 48KHz sampling rate and noise filtering.
In my opinion, the deciding factor here is your phone's port, not the brand. If you are on a Lightning iPhone, the JSAUX Headphone Adapter is the one I would buy — MFi certification, full inline control and a compact aluminum-and-nylon build make it the lower-risk choice for that ecosystem. If you have moved to a USB-C iPhone or use a USB-C laptop and own Beats headphones, I would buy the Toeasor USB C Solo instead, because it removes the adapter entirely and adds a mic and volume controls in the process. They are not really competing for the same buyer — they are two clean answers to two different ports. Check the current price on Amazon before you commit, since the difference in cost between them may sway you.
No. JSAUX lists Lightning devices only — iPhone 14 series and earlier, plus Lightning iPads and iPod touch. The iPhone 15, 16 and 17 families use USB-C, so you would want the Toeasor USB C Solo or a similar USB-C solution instead.
It should work with any headphones that have a standard 3.5mm jack port, since the headphone end is a 3.5mm male plug. The fit list is written around Beats models, but the description notes compatibility with other 3.5mm-jack headphones as well.
Both claim to. JSAUX says volume, previous/next, pause, calls and Siri all work as usual through the adapter. Toeasor builds a microphone, volume buttons and a multi-function button directly into the cable.
I would lean toward the Toeasor USB C Solo for USB-C devices, because wired mode removes Bluetooth latency and it does not depend on an adapter. For a Lightning iPhone, the JSAUX adapter is the equivalent wired route, with its 48KHz sampling and noise filtering.
