If you want a single-purpose cable that fast-charges a long list of Anker Soundcore earbuds and headphones from any USB-A outlet, choose Aiivioll USB C Charger; if you need a 3-in-1 USB-C splitter that lets you listen through a 3.5mm or USB-C headphone jack while your phone keeps fast charging up to 60W PD, choose caojunzhen USB-C.
Aiivioll USB C Charger vs caojunzhen USB-C at a Glance
• Aiivioll USB C Charger — biggest strength: a USB-A to USB-C charging cable rated up to 2A, with a claimed 10,000+ plug/unplug cycle build and a huge Anker Soundcore compatibility list.
• Aiivioll USB C Charger — biggest trade-off: it is a charging and data cable only. It carries no audio adapter function, so it cannot turn a phone's USB-C port into a headphone jack.
• caojunzhen USB-C — biggest strength: three ports in one small adapter — 3.5mm audio, USB-C audio, and USB-C charging up to 60W PD — so you can charge and listen at the same time.
• Pick Aiivioll USB C Charger if you own Soundcore earbuds or headphones and just want a spare or replacement fast-charging cable that stays in a bag or at a desk.
• Pick caojunzhen USB-C if your phone has no headphone jack and you want wired audio plus charging from one USB-C port.
The Aiivioll USB C Charger is a USB-A to USB-C cable, one meter long, with a round PVC jacket in black. That is the whole idea, and that simplicity is exactly why it works for a lot of people. It is built for the person whose Soundcore earbuds came with a short cable that got lost, chewed by a pet, or left in a hotel room. Plug one end into any USB-A wall charger, power bank, or laptop port, plug the other into the earbuds case, and you are charging.
The spec that matters most here is the fast-charge claim. Aiivioll rates it for up to 2A and says a 10-minute top-up on models like the Life A1, A2 NC, Dot 2, P2 and Note gives roughly 1.5 hours of playback when paired with a 1.5A-or-higher AC adapter. Read that carefully: the cable is only half the equation. Your wall adapter has to be able to push the current. Pair it with a weak 1A brick and you get a slow trickle no matter what the cable can handle.
The compatibility list is unusually broad for a budget cable. It names Soundcore Life A1, A2 NC, Dot 2, P2, P2 Mini, P2i, P3, P3i, P20i, P40i, A20i, A3i, Note, Note 3S, Q35, Q30, Q20+, Q20i and Q10 headphones, plus Space Q45, Sport X10, Space One, Space A40, Liberty 4, Liberty Air 2, Air 2 Pro, Liberty 3 Pro, Liberty 2 and Liberty 2 Pro earbuds. It also lists a pile of Soundcore speakers — Mini 3, Soundcore 3, Motion Boom, Motion Boom Plus, Flare 2, Boost, PowerConf and more. If your gear is on that list, you already know it will fit.
Who should skip it? Anyone who needs an audio adapter, a USB-C-to-USB-C cable, or a cable for a non-Soundcore device that uses a different connector. This is a USB-A-to-USB-C cable with a specific job.
caojunzhen USB-C: Who It's For
The caojunzhen USB-C is a completely different animal. It is a 3-in-1 adapter that plugs into your phone's USB-C port and splits it into three: a 3.5mm headphone jack, a USB-C headphone jack, and a USB-C charging port. The pitch is simple and very real for modern phone owners — stop choosing between listening and charging.
The charging side supports up to 60W PD passthrough. That is a serious number, and it means the adapter is not a weak dongle that trickles power while you use it. If your phone fast-charges over USB-C PD, this adapter is designed to pass that power through rather than choke it. The audio side uses a Hi-Fi DAC, which is the part that converts digital audio to analog for wired headphones. caojunzhen lists it as compatible with iPhone 15 and Samsung S24, which makes sense since both use USB-C.
There is one rule you absolutely must know before buying: the 3.5mm jack and the USB-C headphone jack cannot be used at the same time. So you pick wired headphones on one connector or the other, and charge on the third. If you were imagining plugging in two sets of headphones simultaneously, that is not what this does.
The other practical details: it is an auxiliary-type connector with three ports, and it carries a 6-month warranty. That warranty is shorter than the 12-month promise Aiivioll offers, which is worth noting if long-term coverage matters to you.
Side-by-Side: Which Should You Choose?
• Best for charging Soundcore earbuds and headphones → Aiivioll USB C Charger. Its compatibility list is built around exactly that gear.
• Best for wired audio on a jackless phone → caojunzhen USB-C. It restores a 3.5mm and a USB-C headphone option in one plug.
• Best for charging while listening → caojunzhen USB-C. 60W PD passthrough plus audio at the same time is the whole point.
• Best for a rugged everyday cable → Aiivioll USB C Charger. The claimed 5,000+ bend and 10,000+ plug-cycle figures are aimed at wear and tear.
• Best for a quick top-up before a commute → Aiivioll USB C Charger, provided you use a 1.5A-or-higher adapter to actually get the fast-charge behavior.
• Best for travel with one small accessory → caojunzhen USB-C. Three functions in one adapter beats carrying a dongle plus a separate charging cable.
• Longest stated coverage → Aiivioll USB C Charger. 12 months versus 6 months on the caojunzhen.
• Best for a USB-C-to-USB-C phone charging cable → neither. Aiivioll is USB-A to USB-C, and caojunzhen is an adapter, not a straight cable.
In my opinion, the right pick comes down to one question: are you charging earbuds, or are you trying to get wired audio out of a phone that removed the jack? If it is the first, I would buy the Aiivioll USB C Charger — the compatibility coverage, the 2A fast-charge rating and the longer warranty make it the more useful everyday accessory for Soundcore owners. If it is the second, the caojunzhen USB-C is the one I would take, because no charging cable can give you a headphone jack. They solve different problems, and only one of them solves yours. Check the current price on Amazon before you commit.
how to charge headphones
Plug the charging cable into the headphone or earbud case and the other end into a power source. With the Aiivioll cable, that means a USB-A outlet — a wall adapter, laptop port or power bank. Use a 1.5A-or-higher adapter if you want the fast-charge behavior the cable is rated for.
how to charge headphones faster
The cable is only half the story — the adapter matters just as much. Aiivioll rates this cable up to 2A and says a 10-minute charge on supported Soundcore models yields up to 1.5 hours of playback when paired with a 1.5A-or-more AC adapter. A weak charger will hold you back regardless of the cable.
is fast charging bad for headphones
There is nothing in these spec sheets suggesting fast charging damages headphones. Aiivioll states the cable automatically adjusts to the power the device needs and that charging runs cool without harming the device. Your headphones' own charging circuitry ultimately governs how much current they accept.
how to fast charge bose headphones
Neither product here is a Bose charging cable. The Aiivioll USB C Charger is built around Anker Soundcore models, and the caojunzhen USB-C is an audio-and-charging adapter for phones. For Bose, match a cable to Bose's own connector and use a charger rated at or above what Bose specifies.
