We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want to keep using your existing Lightning EarPods while topping up your iPhone, choose Opluz iPhone Splitter; if you need to fast charge a modern USB-C phone or laptop while listening on regular 3.5mm headphones, choose BAVNCO USB C.
• Opluz iPhone Splitter — biggest strength: dual Lightning design that feeds both a Lightning headset and a charge cable at once, with support for up to 2.4A charging and 48 KHz / 24-bit audio.
• Opluz iPhone Splitter — biggest trade-off: it is a Lightning-only accessory, so it is useless on USB-C iPhones and tablets, and it will not drive a standard 3.5mm headphone plug.
• BAVNCO USB C — biggest strength: one USB-C port becomes a 3.5mm aux jack plus a PD 60W charging path, so you can listen on ordinary wired headphones while fast charging a phone, tablet or laptop.
• BAVNCO USB C — biggest trade-off: no data transfer at all, and you need a PD wall charger and PD cable to actually see the 60W speeds.
• Pick Opluz iPhone Splitter if you are on an older Lightning iPhone or iPad and want to keep your Apple-style wired headset.
• Pick BAVNCO USB C if you have a newer USB-C device and want the flexibility of standard 3.5mm headphones plus fast charging.
The Opluz adapter is a two-in-one Lightning splitter. One port takes a Lightning headphone or Lightning EarPods, the other takes your Lightning charging cable, and both can run at the same time. That is the whole point of the design: you can listen to music, take a call, use the mic and remote, or game while the phone is still charging. It supports up to 2.4A charging and the built-in chip is there to keep the voltage and current stable rather than letting it spike.
Audio is handled by a dedicated DAC chip with noise-reduction processing, and Opluz rates the output at up to 48 KHz and 24-bit. In practice that means it is built to preserve the sound of a Lightning headset rather than degrade it, and the adapter is listed as compatible with both CTIA and OMTP wiring standards. The listing also states it is Apple MFi certified, which matters because uncertified Lightning audio adapters are the ones that tend to throw an error message on screen.
BAVNCO USB C: Who It's For
BAVNCO takes the opposite approach. It plugs into a USB-C port and splits it into a 3.5mm aux jack and a PD charging port rated up to 60W. So the headphones you already own — the ones with a normal 3.5mm plug — keep working, and the charging side can push serious wattage, enough that BAVNCO lists phones, tablets and laptops among the devices it can power. That is a genuinely different class of charging from a 2.4A Lightning splitter.
Audio runs through a smart DAC decoding chip and BAVNCO markets it as lossless HIFI with no current noise, aimed at music listeners, podcast fans and gamers. The built-in chips negotiate the voltage and current each device needs, which is what lets the same dongle serve a phone and a laptop without you thinking about it. Two honest caveats: it does not support data transfer, and BAVNCO itself recommends pairing it with a PD wall charger and PD cable for proper speeds.
Compatibility is the other headline. The list covers iPhone 17/16/15 Pro Max/Plus, Galaxy S26 and S25 series back through S8, Note 20 down to Note 8, iPad Pro and iPad mini, MacBook Pro/Air, Google Pixel 10 through 6, OnePlus, Huawei Mate, Dell XPS, HP Chromebook, Surface Book 3, Samsung tablets, LG V40 and even the Steam Deck and PS5. That is a broad net.
Who should buy it: anyone on modern USB-C hardware who wants one dongle for both ordinary wired headphones and fast charging, especially travellers and students who move between a phone and a laptop. Who should skip it: Lightning-only iPhone owners, anyone who needs a data connection through the same port, and anyone who wants to charge at high speed without a PD charger on hand. It comes with 365 days of after-sales service.
Side-by-Side: Which Should You Choose?
• Best for keeping your current headphones → it depends entirely on the plug. Lightning headset: Opluz. 3.5mm headset: BAVNCO.
• Best for older iPhones and Lightning iPads → Opluz iPhone Splitter. It is purpose-built for that connector generation.
• Best for modern iPhones, Galaxy, Pixel, MacBook and Steam Deck → BAVNCO USB C, simply because its compatibility list is far wider and current.
• Best for headphone features → Opluz iPhone Splitter if your headset is Lightning, since it passes through mic, call audio and remote controls; BAVNCO is aimed at plain 3.5mm listening.
• Best for audio spec headroom → a tie in kind, not in numbers. Opluz quotes 48 KHz / 24-bit with noise reduction; BAVNCO leans on a smart DAC chip for lossless HIFI with no current noise. Both claim clean output, measured differently.
• Best for travel and everyday carry → BAVNCO USB C, because one dongle covers more of your devices and the 60W side doubles as your laptop charger path.
• Best if you refuse to carry a PD charger → Opluz iPhone Splitter, since it works off your existing Lightning cable without extra conditions.
In my opinion, I would buy the BAVNCO USB C for most people shopping in 2026. The reason is coverage: PD 60W charging plus a 3.5mm jack fits phones, tablets and laptops, and it works with the ordinary wired headphones almost everyone already owns. The Opluz is the smarter buy only in one specific situation — you are still on a Lightning iPhone or Lightning iPad and you want to keep using a Lightning headset with mic and remote support intact. If that is you, Opluz is the better fit. If you are on USB-C, BAVNCO is the one I would take.
how to charge headphones faster
Fast charging depends on the adapter and the charger behind it, not the headphones alone. The BAVNCO USB C supports up to 60W PD, but it only reaches that with a PD wall charger and PD cable — BAVNCO recommends using both. The Opluz tops out at 2.4A over Lightning.
how to charge headphones
With either adapter you plug the charging cable into the adapter's charge port and the headphones into the audio port, then connect the adapter to your phone. That lets audio and charging run at the same time instead of forcing you to choose one. The Opluz uses Lightning in and out; the BAVNCO uses USB-C in with a 3.5mm jack out.
how to fast charge bose headphones
Neither adapter charges headphones directly — they charge the phone or laptop the headphones are plugged into. So the headphone brand does not change anything here. What matters is your device's connector: Lightning for the Opluz, USB-C for the BAVNCO, and a PD charger for full BAVNCO speed.
is fast charging bad for headphones
No — these adapters charge your phone, not your headphones, and both are built with chips that regulate voltage and current to protect the connected device. Opluz uses a smart chip for stable charging; BAVNCO uses chips that negotiate each device's requirements. Neither design routes fast-charge current into the headphone driver.
