If you want to listen to wired headphones and charge your phone at the same time through one USB-C port, choose Subynanal USB c; if you need to pull a snapped-off 3.5mm plug out of a headphone jack, choose yboueo Headphone Plug Extraction. These two products share the words "USB-C" and "3.5mm" and almost nothing else. One is a daily-use audio adapter. The other is a single-purpose repair tool you hope you never need. Here's how to tell which one actually belongs in your cart.
• Subynanal USB c — biggest strength: a true 2-in-1 design that runs audio through a 3.5mm aux jack while passing up to 60W of PD charging, with a built-in DAC rated for 32bit/384KHz playback.
• Subynanal USB c — biggest trade-off: it does not support data transfer, and the manufacturer notes QC fast charging may not work on some newer phones — a PD wall charger is the recommended pairing.
• yboueo Headphone Plug Extraction — biggest strength: a 12-pack of thin-wall stainless steel tubes (0.1mm wall thickness) purpose-built to grip and extract broken 3.5mm plugs from phone, laptop and tablet jacks.
• yboueo Headphone Plug Extraction — biggest trade-off: the brand itself calls it a single-use tool and openly states it can't guarantee success in every breakage scenario, since it depends entirely on how and where the plug snapped.
• Who each is for: Subynanal for anyone whose phone dropped the headphone jack but who still wants wired audio plus charging; yboueo for anyone staring at a broken plug stuck inside a jack right now.
The Subynanal adapter solves a very specific modern annoyance: the phone in your pocket has one USB-C port, and you want to use it for two things at once. This dongle splits that port into a 3.5mm audio jack and a USB-C PD charging input, so music or a call keeps playing while the battery tops up. According to the spec sheet, the charging side supports up to 60W PD (20V/3A) and uses an EJ899M chip that identifies the voltage and current each device needs — that's the kind of regulation that protects your phone from a sloppy charge.
Who should buy it: iPhone 15/16/17 family owners, Galaxy S20-through-S24 users, Pixel 6/7/8/9 owners, iPad Pro and MacBook users — basically anyone with a USB-C port and a pair of wired headphones they refuse to give up. It's also genuinely useful for long calls or gaming sessions where you can't afford to drain the battery.
Who should skip it: anyone hoping to transfer files through it — the sheet is explicit that data transfer is not supported. And if you're on a phone that relies on QC rather than PD charging, the manufacturer warns results may vary; they recommend a PD wall charger for the fastest speeds. If your phone still has a real 3.5mm jack, you don't need this at all.
yboueo Headphone Plug Extraction: Who It's For
This is not a gadget. It's a repair kit for one bad moment: the tip of your 3.5mm headphone plug snaps off and stays lodged inside the jack. The yboueo set gives you 12 thin stainless steel tubes designed to slide into the tiny gap between the jack wall and the broken plug, grip it, and pull it free. The instructions are straightforward — insert the tube deep enough (the headphone hole is about 0.55 inch deep), press gently until you feel it grab, then tighten the tube end by hand or with pliers and pull. The brand claims the job can be done in about 20 seconds.
The honest part of the spec sheet is worth reading twice. yboueo states the tube wall is 0.1mm thick and that they can't make it thinner — that thinness is the entire reason the tool can fit into the gap at all. They also say plainly that every breakage is different, that they can't guarantee the tool suits every case, and that if the broken plug sits in a way the tube can't reach, it won't work. They call it a single-use tool, which is why it ships as a 12-pack: if one attempt fails or the tube deforms, you have spares. Compatible with 3.5mm jacks on phones, laptops, tablets and "any other devices" with that jack size.
Who should buy it: anyone with a broken plug stuck in a phone, laptop or tablet jack, who would rather try a cheap extraction before paying a repair shop or replacing the device. The 12-pack also makes sense for a household, a school, or anyone who handles a lot of shared audio gear.
Who should skip it: anyone whose jack is damaged in some other way, or whose broken piece is wedged in a position the tube physically can't reach. Also skip it if you're expecting a guaranteed fix — the brand itself won't promise that, and I respect them for saying so.
• Best for listening while charging → Subynanal USB c. It's the only one of the two that does audio and power at once.
• Best for rescuing a dead headphone jack → yboueo Headphone Plug Extraction. The Subynanal adapter cannot remove anything from a jack; that's simply not its function.
• Best for sound quality ceiling → Subynanal USB c. 32bit/384KHz support on paper beats the typical 24bit/96KHz adapter.
• Best for charging headroom → Subynanal USB c. Up to 60W PD with voltage/current identification via the EJ899M chip.
• Best everyday carry → Subynanal USB c. 13cm, roughly 4.5 grams, plug and play with no drivers.
• Best for one-time emergencies → yboueo Headphone Plug Extraction. A 12-pack of single-use tubes that sit in a drawer until the day you need them.
• Best for iPhone 15/16/17, Galaxy, Pixel, iPad and MacBook owners → Subynanal USB c, based on the listed compatibility.
• Best for phones, laptops and tablets with a 3.5mm jack → yboueo Headphone Plug Extraction, since the tool targets the jack itself rather than any particular model.
If I had to pick one, I'd buy the Subynanal USB c — in my opinion it's the product you'll actually use, week after week, because it removes a daily friction (choosing between music and battery) rather than fixing a rare accident. It also lists a 12-month warranty and a genuinely broad compatibility range. That said, the yboueo tool is cheap insurance for a specific disaster, and if you're holding a device with a snapped plug inside it right now, that's the one you need today. They're not competitors. They're answers to two different questions. Check the current price on Amazon for whichever one matches your situation.
FAQ
It's built for 3.5mm jacks on phones, laptops, tablets and similar devices. But yboueo states clearly that every breakage is different and they can't guarantee it works in every case — the tube must be able to reach the broken piece.
It supports up to 60W PD charging, and the manufacturer notes it may not support QC on some newer phones. They recommend using a PD wall charger for the faster speeds. Data transfer is not supported at all.
If your phone has no headphone jack and you still use wired headphones, get the Subynanal adapter. If you have a plug snapped off inside a jack right now, get the yboueo extraction set. Most people will only ever need one of them.
