How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a simple, purpose-built replacement charging cord for 3.5mm-jack headphones, choose Gneinour Studio Charge Cable; if you need to listen, charge and move data at the same time on a modern USB-C phone or laptop, choose Pubiohs USBC Splitter 1.
These two look like they belong in the same drawer, but they solve completely different problems. One is a single-purpose charging cable for older headphone designs. The other is a small adapter hub that turns one USB-C port into several. Pick the wrong one and it simply won't do the job — so let's sort out which job you actually have.
• Gneinour Studio Charge Cable — biggest strength: Charges and transfers data through a 3.5mm jack-to-USB connection, with gold-plated contacts, tinned copper conductors and a 2A maximum current.
• Gneinour Studio Charge Cable — biggest trade-off: It is a charging and data cable only, not an audio cable, so it will not play sound from your phone.
• Pubiohs USBC Splitter 1 — biggest strength: Splits one USB-C male plug into a 3.5mm audio jack, a USB-C headphone/data jack and a USB-C charging port, with a built-in DAC rated up to 32-bit/384kHz.
• Pubiohs USBC Splitter 1 — biggest trade-off: It only works with digital USB-C headphones and only one headphone jack can be active at a time; it also won't do 100W fast charging or charge laptops.
• Who the Gneinour cable is for: Owners of Beats Studio/Solo Wireless or other 3.5mm-to-USB headphones who need a dependable replacement charge cord.
• Who the Pubiohs splitter is for: USB-C phone, iPad and laptop users who want to charge while listening on digital headphones and still move data.
The Gneinour Studio Charge Cable is a replacement cord, plain and simple. One end is a 3.5mm male jack, the other is a USB 2.0 Type-A male plug, and it exists to push power and data into devices that charge through a 3.5mm port. The spec sheet lists a 2A maximum current, gold-plated connectors, four-core tinned copper conductors and a 480 Mbps data rate — the kind of numbers that tell you this is built for steady charging and sync rather than audio playback.
What stands out to me is the durability framing. The PVC jacket is described as high elasticity, with a 10,000-bend test behind it, plus a tangle-free design and a compact 1m / 3.3ft length. At just 5 grams in red, round profile, it's the sort of cable you can leave plugged into a laptop or power adapter and forget about. The multiple protection systems — over-voltage, over-charging and over-heating safeguards — matter here too, because headphones with small internal batteries are exactly the devices you don't want cooked by a sloppy charger.
Who should buy it? If you own Beats by Dre Studio Wireless or Solo Wireless headphones, or any other headphone, MP3 player, pocket recorder, speaker or iPod shuffle that charges over a 3.5mm plug-to-USB connection, this is a direct-fit replacement. Who should skip it? Anyone expecting to hear music through it. Gneinour states clearly this is a charging jack, not an audio cable. If your headphones have a USB-C port, or you want to listen and charge at the same time, this isn't your product — the Pubiohs adapter is.
The Pubiohs USBC Splitter 1 is the opposite kind of accessory: it adds ports instead of replacing one. A single USB-C male connector fans out to three female ports — a 3.5mm audio jack, a USB-C headphone jack that also handles data, and a USB-C charging port. That's the whole pitch: charge your phone while you listen, take a call, game or watch video, and still transfer data. Plug and play, no software.
The audio side is where Pubiohs makes its strongest claims. There's a built-in intelligent DAC chip rated up to 32-bit/384kHz, which the brand positions against the more common 24-bit/96kHz ceiling. The stated goal is HiFi sound with static and distortion eliminated through precise signal paths and no current noise. It also supports microphone input and volume adjustment, and the input side accepts both USB-C and Lightning, which is why the compatibility list runs from iPhone 7/8/X era models all the way up to iPhone 17 series and most Type-C Android devices.
Now the trade-offs, and they're significant. This adapter is for digital USB-C headphones only — analog headphones won't work, and Pubiohs tells you to test whether your headphone shows up as an external USB audio device first. Only one audio jack can be live at a time; connect two and you get silence. It doesn't support 100W fast charging, so laptops and iPad Pro are out, and it won't charge connected speakers. On some iPads, tablets, laptops and MacBooks you also have to manually select "USB Audio 2.0" the first time. Buy it if you have digital USB-C headphones and a phone that needs charging while you listen. Skip it if your headphones are analog, or if you're hoping to fast-charge a laptop through it.
Side-by-Side: Which Should You Choose?
• Best for replacing a lost or frayed headphone charge cord → Gneinour Studio Charge Cable. It's a direct 3.5mm-to-USB replacement with a 2A rating and a bend-tested PVC jacket.
• Best for audio quality → Pubiohs USBC Splitter 1. The built-in DAC rated to 32-bit/384kHz is an audio feature the Gneinour cable simply doesn't have.
• Best for data transfer alongside charging → Pubiohs USBC Splitter 1. It handles data on the USB-C headphone jack, while the Gneinour cable tops out at 480 Mbps sync.
• Best for old-school 3.5mm-port devices → Gneinour Studio Charge Cable. MP3 players, pocket recorders, speakers, iPod shuffle and 3.5mm-plug headphones are exactly its compatibility list.
• Best for iPhone and modern Android users → Pubiohs USBC Splitter 1. Its Lightning and USB-C inputs cover a very wide phone range, from older iPhones through the latest models.
• Best for travel and throw-in-a-bag simplicity → Gneinour Studio Charge Cable. At 5 grams, 1m and tangle-free, it disappears into any pocket.
• Best for a single compact adapter instead of a dongle pile → Pubiohs USBC Splitter 1. Audio, charging and data all come out of one small hub.
If I had to pick one for myself, I'd buy the Pubiohs USBC Splitter 1 — but only because my daily setup is a USB-C phone and digital headphones, where charging and listening at the same time is a genuine daily annoyance it solves. In my opinion it's the more capable, more modern accessory of the two, and the DAC spec plus mic and volume support make it the better fit for calls and video. That said, if your headphones are the classic 3.5mm-jack, USB-charged kind — Beats Studio or Solo Wireless, an old MP3 player, a pocket recorder — the Gneinour Studio Charge Cable is the honest, no-nonsense answer, and the splitter would be useless to you. Match the accessory to the port on your device and you'll be happy either way. Check the current price on Amazon before you commit.
No. Gneinour states it is a 3.5mm jack charging cable, not an audio cable. It carries power and data up to 480 Mbps, but it will not play sound into your headphones.
Only if they're digital USB-C headphones. Pubiohs advises testing your headphone on a digital-audio-only device first — if it's recognized as an external USB audio device, it's digital and the adapter will work. Analog headphones are not supported.
No. It doesn't support 100W fast charging, so laptops and iPad Pro aren't suitable, and charging connected speakers isn't supported either. It's intended for phones and similar small devices.
No. Only one headphone jack and the charging jack can be connected at a time. If you connect two audio jacks simultaneously, you won't hear any sound.
It's 1m / 3.3ft, tangle-free, and made of PVC described as high elasticity with a 10,000-bend test behind it. It weighs 5 grams, so it's easy to store and carry.
