How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want the stronger fast-charge ceiling for a USB-C-only setup, choose JBJBBG USB C Splitter，2; if you need one dongle that also fits Lightning iPhones and legacy 3.5mm headsets, choose Opluz Lightning&USB C. That's the short version, and it's the version I'd give a friend setting up a call center desk, where one cable has to charge a phone and carry a headset at the same time without drama.
• JBJBBG USB C Splitter，2 — biggest strength: PD 100W USB-C fast charging paired with a Realtek DAC Hi-Res audio chip, so one cable handles USB-C earphones and serious power delivery at once.
• JBJBBG USB C Splitter，2 — biggest trade-off: It lives entirely in USB-C land. No Lightning port, and no 3.5mm jack, so older headsets are out.
• Opluz Lightning&USB C — biggest strength: Three ports in one short dongle — Lightning, USB-C and a 3.5mm aux jack — plus MFi certification and 60W PD charging.
• Opluz Lightning&USB C — biggest trade-off: The charging ceiling is lower at 60W, and it's built around the 3.5mm plug rather than native USB-C audio.
• Choose JBJBBG if your phone, tablet or laptop is USB-C and you want maximum charging headroom plus a clean digital audio path.
• Choose Opluz if you mix Apple Lightning devices with USB-C gear, or you still rely on a 3.5mm headset.
This is a USB-C-to-dual-USB-C adapter, and that phrase matters. One port takes a USB-C headphone, the other takes your charging cable, and the two run side by side. The charging side is PD 100W, which is a lot of headroom — enough that the adapter itself is unlikely to be the bottleneck on a modern phone, tablet or laptop that supports USB-C Power Delivery. The audio side uses a Realtek DAC Hi-Res decoding chip, and the spec sheet is explicit about what that buys you: stable, lossless signal transmission with no current noise. For a headset you wear eight hours a day, "no current noise" is not a marketing footnote, it's the difference between a clean voice on the other end of the line and a faint hiss that everyone notices but you.
The build details are quietly sensible. Tin-plated thickened copper core for the charging path, TPE outer material, phone call and volume control support, and a listed weight of 0.02 kg — light enough that it won't drag on a headset cable. Color is grey. Compatibility is broad and specific: iPhone 16 and 15 families, iPad Pro 2018 through 2021, iPad Air, iPad Mini, MacBook and MacBook Pro/Air, Galaxy S23 down through S10 and Note10, Pixel 7 down to Pixel 2, plus Huawei and LG devices. Plug and play, no driver talk.
Opluz Lightning&USB C: Who It's For
Opluz takes the opposite approach: instead of two USB-C ports, it gives you three ports — USB-C, Lightning and a 3.5mm audio jack — in a dongle that's only 14 cm long. Charging runs through PD 60W. Audio runs through a built-in smart DAC decoding chip, again with the no-current-noise promise, and the spec sheet notes it won't hurt your ears. The Lightning port carries MFi certification, which in practice means no error message pop-up when you plug into an Apple device — a genuinely useful detail if you've ever had a cheap adapter throw a compatibility warning mid-call.
The feature list is broader than JBJBBG's in one specific way: audio and charger dongle support for call function, charging, headphone control, data transfer, microphone and remote control. So inline mics and volume buttons on a 3.5mm headset should keep working through the adapter. Compatibility covers both Lightning phones (iPhone 16 and 15 down through the 6/6S generation) and all USB-C devices, plus iPad, Samsung, Pixel, Huawei and LG.
Who should buy it: the person with a mixed drawer. An older Lightning iPhone for personal use, a USB-C work phone, and a comfortable 3.5mm headset you refuse to replace — Opluz handles all three without swapping cables. Who should skip it: if you've moved fully to USB-C and your headset is USB-C native, you're paying in complexity for ports you'll never use, and the 60W charging ceiling is lower than JBJBBG's 100W.
• Best for maximum fast charging → JBJBBG USB C Splitter，2. PD 100W versus PD 60W is the single clearest gap between these two.
• Best for mixed Apple and USB-C households → Opluz Lightning&USB C. The Lightning port plus MFi certification is something JBJBBG doesn't offer at all.
• Best for keeping an existing 3.5mm headset → Opluz Lightning&USB C. That aux jack is the whole point of the design.
• Best for a pure USB-C headset → JBJBBG USB C Splitter，2. Native USB-C audio, Realtek DAC, no analog conversion in the chain.
• Best for travel and tight desks → Opluz Lightning&USB C. At 14 cm and 0.01 kg it's the smaller, lighter object.
• Best for a laptop-plus-phone charging setup → JBJBBG USB C Splitter，2. Higher PD headroom matters more on bigger devices.
• Best for call center phone banks with mixed handsets → Opluz Lightning&USB C. It adapts to whatever the agent is handed.
• Best for a single-platform desk you'll keep for years → JBJBBG USB C Splitter，2. Fewer ports, fewer compromises.
I'd buy the JBJBBG USB C Splitter，2 for a call center setup where every device is USB-C. In my opinion, the combination of PD 100W charging and a Realtek Hi-Res DAC is the more focused piece of engineering — it does one job, and the spec sheet suggests it does that job without the noise floor or charging bottleneck that would annoy me over a full shift. The Opluz is the smarter pick only if you genuinely still touch Lightning devices or a 3.5mm headset. If that's you, buy the Opluz without hesitation. If it isn't, don't pay for ports you'll never use. Either way, check the current price on Amazon before you commit, since both are budget accessories and the gap between them moves.
You can't force a headset to charge faster than its own input allows. What you can do is remove the bottleneck on the source side: the JBJBBG adapter passes through PD 100W, and the Opluz passes PD 60W, so whichever you pick won't be the limiting factor on a phone that supports Power Delivery. Use a charging brick and cable rated above your headset's input, and the headset will draw what it's designed to draw.
Two things matter: the power source and the cable path. Both adapters here support USB-C PD fast charging while audio plays, which means you're not choosing between listening and topping up. Beyond that, the speed is set by the headset itself — a headset rated for slow trickle charging stays slow no matter what you plug it into. Match a capable charger to a capable headset and you'll see the difference.
Plug the headset into the audio port and your charging cable into the power port. On the JBJBBG that means a USB-C headset in one port and a USB-C charging cable in the other. On the Opluz you have three ports to work with — USB-C, Lightning and 3.5mm — so you choose the audio connection that matches your headset and use the USB-C port for power. Both are plug and play.
Not inherently, and both adapters are built with that concern in mind. JBJBBG specifies a tin-plated thickened copper core for safe, stable fast charging and states it won't hurt the phone or lose power. Opluz specifies a smart DAC chip and MFi certification on the Lightning side. The adapter negotiates power delivery rather than dumping current, so the risk sits with a poorly made charger, not with a properly rated adapter.
