• MTAKYI 2-in-3 — biggest strength: a genuine multi-tool. USB OTG camera/keyboard support, a 3.5mm jack and a Type-C charging port in one small white adapter, with a built-in DAC chip.
• MTAKYI 2-in-3 — biggest trade-off: it is an adapter, not a finished cable, and the two headphone paths (3.5mm and Type-C) cannot be used at the same time.
• Toeasor USB C Solo — biggest strength: a clean USB-C-to-3.5mm cable with an inline mic and volume remote, built specifically for Beats models and rated for 10,000 bends.
• Toeasor USB C Solo — biggest trade-off: it only connects a 3.5mm headphone to a USB-C device. No OTG, no card reader, no charging pass-through, and no Lightning support.
• Who each pick is for: MTAKYI for the phone-as-workstation person who wants one tiny accessory in a pocket; Toeasor for the Beats owner who just wants wired audio back.
The MTAKYI 2-in-3 is a pocket adapter that does three jobs at once. One end is a Lightning + USB-C connector; the body splits into a USB port for OTG devices, a 3.5mm AUX jack, and a Type-C port for charging or a Type-C headset. Plug in a USB keyboard and you get faster typing on a phone or tablet. Plug in a USB camera, card reader, U disk, microphone, electric piano or mouse, and it works. That is a lot of capability in something measuring a fraction of an inch per side and weighing about 0.03 kg.
For audio, the built-in DAC chip is the interesting part. It means the 3.5mm female port handles both CTIA and OMTP wiring, so older and newer headsets both behave. MTAKYI also states the 3.5mm port supports listening and charging at the same time through the Lightning charging port — useful if you are in a long call or a long gaming session and the battery is sliding. The one rule to remember: the two headphone paths cannot run simultaneously. Pick 3.5mm or Type-C, not both.
Buy it if you carry one phone or tablet and want wired audio, a USB accessory port and charging from a single item — the traveler, the student, the person who types long messages with a real keyboard. Skip it if you only ever need to connect one pair of 3.5mm headphones to one phone; a plain cable does that with less bulk, and this adapter is overkill. There is a 12-month warranty and it is plug-and-play with no app.
Toeasor USB C Solo: Who It's For
The Toeasor USB C Solo is a different animal entirely: it is a replacement audio cable, not an adapter. One end is USB-C, the other is a 3.5mm male plug, and the whole point is to let a pair of Beats headphones plug straight into an iPhone 17/16/15, a tablet, a laptop or a gaming console without a dongle in between. The connector type is listed as 3.5mm male to USB Type-C, and the cable ships in black and red.
The Beats fit list is the headline: Solo 4, Solo 3, Solo Pro, Solo HD, Solo2, Studio Pro, Studio 3, Studio 2, Detox, Wireless, Mixr, Executive, Pro and Pill headphones, plus other 3.5mm-jack headphones. If you lost or frayed the original cable on a pair of Solos, this is the intended fix.
Then there is the inline remote: microphone, volume up/down, and a multi-function button for play/pause and answering or ending calls. That matters more than it sounds. Once you switch a Beats headphone to wired mode, the on-ear controls often stop working — this cable gives them back at your fingertips.
Construction is where Toeasor makes its claims: oxygen-free copper conductors, a 24K gold-plated straight connector to resist corrosion, TPE outer material, and a stated 10,000 bending test rating with a tangle-free design. The stated goal is stereo sound quality matching the original cable.
Buy it if you own Beats headphones and want zero-latency wired audio for gaming or media, or you want to save the headphone's internal battery by skipping Bluetooth. Skip it if you need Lightning support, OTG accessories, charging pass-through or anything beyond a single audio connection — none of that is here.
Side-by-Side: Which Should You Choose?
• Best for a phone-as-hub setup (keyboard, mouse, card reader, USB mic) → MTAKYI 2-in-3.
• Best for Beats headphone owners → Toeasor USB C Solo, given the explicit Solo/Studio/Mixr/Executive/Pill fit list.
• Best for inline call and volume control on a wired headset → Toeasor USB C Solo, which builds the mic and remote into the cable.
• Best for Lightning devices (iPhone 14 and older, older iPads) → MTAKYI 2-in-3. The Toeasor cable is USB-C only.
• Best for durability against daily coiling → Toeasor USB C Solo, on paper, thanks to the OFC copper, TPE jacket and 10,000-bend rating.
• Best for something that disappears into a pocket → MTAKYI 2-in-3, at roughly 0.03 kg and tiny dimensions.
• Best for a single clean connection with no dongle → Toeasor USB C Solo.
If I had to pick one, I would buy the MTAKYI 2-in-3. In my opinion it is the better long-term value because it solves several problems — wired audio, USB accessories, charging — instead of one, and it works across both Lightning and USB-C devices, which is rare in a single adapter. For a glasses wearer who wants one small thing in a bag that handles a headset, a keyboard and a charge cable, that breadth is worth more than a prettier single cable. I would still recommend the Toeasor USB C Solo without hesitation if you own Beats headphones and simply want a reliable replacement cord with working inline controls — that is a narrower job, and it does it well.
They are not really competitors. MTAKYI is a multi-port adapter with OTG, 3.5mm audio and charging; Toeasor is a single USB-C-to-3.5mm cable with an inline mic. Which is better depends on whether you need one connection or several.
Only through the 3.5mm jack, and only if your Beats model has a 3.5mm input — the adapter does not add Beats-specific inline controls. The Toeasor cable is the one designed around Beats models and their remote functions.
It works with USB-C devices such as iPhone 17/16/15, tablets, laptops and consoles. It does not support Lightning, so older iPhones need the MTAKYI adapter instead.
On the MTAKYI 2-in-3, MTAKYI states you can charge through the Lightning port while listening via 3.5mm — but you cannot use both headphone paths at once. The Toeasor cable carries audio only and has no charging function.
Toeasor publishes a 10,000-bend test rating along with OFC copper and a gold-plated connector, so the cable is built for repeated coiling. MTAKYI emphasizes a compact, upgraded multifunction design and backs the adapter with a 12-month warranty.
