How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want to keep using your favourite wired earphones while charging your phone at the same time, choose JSAUX USB C Headphone; if you need wireless earbuds that let you hear traffic and conversation while you run, choose 2B2C Open Ear Earbuds.
• JSAUX USB C Headphone — biggest strength: a 2-in-1 USB-C splitter that gives you a 3.5mm audio jack and a PD 60W charging port at the same time, with a built-in DAC/ADC for Hi-Fi playback and mic support on TRRS headsets.
• JSAUX USB C Headphone — biggest trade-off: it is an adapter, not a listening device. It does nothing without wired earphones, it can't be charged on every OnePlus or Pixel model, and it won't drive Apple EarPods' inline volume controls.
• 2B2C Open Ear Earbuds — biggest strength: a genuinely wireless, over-ear open design at 9g per bud, Bluetooth 5.3 with a 10m range, and a charging case with an LED battery display.
• 2B2C Open Ear Earbuds — biggest trade-off: open-ear means no noise isolation at all, there's no wired fallback and no jack, and the sound relies entirely on Bluetooth plus the case's own battery.
• Who each pick is for: JSAUX for anyone with wired earphones, a USB-C phone and a charging problem. 2B2C for runners, cyclists, delivery riders and office workers who want their ears open and their hands free.
This is one of those small gadgets that solves a very specific, very annoying problem. A lot of modern phones have exactly one USB-C port. Plug in wired earphones and you can't charge. Plug in a charger and your music stops. The JSAUX adapter splits that single port into two: one PD-compatible charging port rated up to 60W, and one 3.5mm jack. Music, games, calls and video keep running while the phone tops up.
The audio side is more serious than the price bracket of most dongles suggests. The DAC handles 24bit/96kHz or 16bit/48kHz playback and the ADC handles 16bit/48kHz, which the spec sheet describes as stable, high-quality output without current noise. The 3.5mm port is CTIA/TRRS compatible. That last detail matters: only TRRS (4-pole) headsets get microphone support, while TS and TRS plugs will play audio only. If you want to take calls or record, check your headset's plug first.
Compatibility is broad but not universal. It's listed for iPhone 16 Pro/16 Pro Max/16/16 Plus, the iPhone 15 series, Galaxy S24/S24+/S24 Ultra/S23/S22/S21, Note 8/9/10/20, iPad Pro and various Huawei Mate and P models. The two clear exceptions are OnePlus and Pixel — it can't charge all models of those. For charging speed you want a PD20W-or-higher wall charger, since QC isn't supported on some phones.
Buy it if you own good wired earphones, your phone has one USB-C port, and you're tired of choosing between listening and charging — on a train, at a desk, or during a long gaming session. Skip it if you've already moved to wireless, if you're on OnePlus or Pixel, or if you mainly use Apple EarPods and expect their inline volume buttons to work. It's also worth noting it doesn't support Apple headphone line control, and unplugging power mid-song restarts the chip, so playback may need to be resumed. It carries a lifetime warranty and needs no drivers.
These are the opposite philosophy. Nothing touches your ear canal. Each earbud hooks around the outside of your ear and weighs about 9g, so the inner ear stays open. The pitch here is comfort over long stretches plus situational awareness — you hear cars, bikes, colleagues and announcements while your audio plays. For running, cycling, hiking or driving, that awareness is the entire point.
The spec sheet lists Bluetooth 5.3 with a 10m range, and multi-function buttons on the buds for play/pause, volume and calls, so you're not reaching for your phone. Sound is handled by a dynamic driver with a 20Hz–20,000Hz range and 16 ohm impedance, described as crystal-clear HD stereo with reduced sound leakage. There's a microphone built in for calls. Noise control is listed as "None" — which is honest, and exactly what open-ear design means.
Battery is where these look strongest on paper. Two hours to a full charge gives up to 8 hours of continuous playback, and the compact magnetic charging case provides roughly 10 additional charges. The case has an LED display showing remaining power and charging status, which is a genuinely useful touch compared with guessing at a blinking dot. A Type-C cable is included. The earpieces are over-ear shaped with silicone and fabric materials, and the color here is pink.
Side-by-Side: Which Should You Choose?
• Best for keeping wired earphones alive → JSAUX USB C Headphone. The 3.5mm jack is the whole product.
• Best for listening and charging at once → JSAUX USB C Headphone. PD 60W charging alongside audio playback is the core feature.
• Best for call and recording support on a wired headset → JSAUX USB C Headphone, provided your headset uses a 4-pole TRRS plug.
• Best for situational awareness and outdoor safety → 2B2C Open Ear Earbuds. Nothing blocks your ear canal.
• Best for all-day comfort without ear fatigue → 2B2C Open Ear Earbuds. Roughly 9g per bud and an around-the-ear fit.
• Best for total battery freedom from a wall outlet → 2B2C Open Ear Earbuds. Up to 8 hours per charge plus about 10 case recharges.
• Best for plug-and-play across many phone brands → JSAUX USB C Headphone, with the notable OnePlus and Pixel charging exceptions.
• Best for pure wireless convenience → 2B2C Open Ear Earbuds. Bluetooth 5.3, no cable, no dongle hanging off your phone.
If I had to pick one for myself, I'd buy the JSAUX USB C Headphone. In my opinion it solves a harder problem: it lets you keep using earphones you already like, adds genuinely decent DAC specs, and removes the charge-or-listen trade-off that single-port phones force on you. The lifetime warranty and driver-free setup make it a low-risk thing to keep in a bag. I'd only steer you to the 2B2C Open Ear Earbuds instead if your priority is wireless freedom and staying aware of your surroundings outdoors — that's where open-ear design wins, and no adapter can replicate it. Whichever way you lean, check the current price on Amazon before deciding, since both sit in very different budget brackets.
Probably not, unless you still use wired earphones or a wired headset for calls. Its value comes entirely from the 3.5mm jack plus simultaneous PD 60W charging. Without wired earphones, there's nothing for it to do.
No. Noise control is listed as none, and the open-ear design is built specifically to let ambient sound in. That's a safety feature outdoors, but it means you'll hear traffic, conversations and machinery over your audio.
The 2B2C Open Ear Earbuds, by a wide margin. They give up to 8 hours of playback per charge, recharge fully in about 2 hours, and the case adds roughly 10 more charges. The JSAUX adapter has no battery — it draws from your phone while passing through PD 60W charging.
It's listed for most iPhone 15 and 16 models, Galaxy S20 through S24, Note 8–20, iPad Pro and several Huawei models. The stated exceptions are OnePlus and Pixel, where it can't charge all models. For full charging speed, use a PD20W-or-higher wall charger.
