How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want the most flexible USB-C audio accessory — one that lets you listen on a 3.5mm headphone, fast charge at 60W, and still connect USB peripherals or move files — choose INVERSE NET USB C; if you need a simple two-port adapter that charges at up to 100W while you listen through a Lightning-style IP headphone jack, choose Liaoan USB C Headphone.
• INVERSE NET USB C — biggest strength: three ports in one (USB-C OTG, 3.5mm headphone jack, 60W PD charging) that work at the same time, plus a built-in DAC rated up to 24bit/96kHz.
• INVERSE NET USB C — biggest trade-off: 60W charging is lower than the Liaoan's 100W, and it's a busier little adapter with more to keep track of.
• Liaoan USB C Headphone — biggest strength: 100W fast charging paired with an IP headphone jack on a clean 2-in-1 body, with a HiFi DAC for clear calls and audio.
• Liaoan USB C Headphone — biggest trade-off: no data transfer and no OTG, so it can't move files or drive USB accessories — it's strictly audio plus charging.
• Pick INVERSE NET USB C if you want one adapter that doubles as a headphone dongle, a charger, and a USB hub.
• Pick Liaoan USB C Headphone if you only ever want to charge and listen, and you'd rather have the higher 100W charging ceiling.
The INVERSE NET USB C is best understood as a small three-in-one dock rather than a plain headphone dongle. Its USB-C end plugs into your device and splits into a USB OTG port, a 3.5mm headphone jack, and a 60W PD charging port — and the listing states all three can work at the same time. That means you can be charging, listening through wired headphones, and reading a USB stick or using a keyboard at once. For someone who moves between a phone, a tablet and a laptop all day, that "everything at once" behavior is the whole point.
Audio is handled by a built-in high-resolution DAC chip rated up to 24bit/96kHz, which the spec sheet describes as a high-fidelity, lossless path for compatible iPads and Android phones. It also supports the everyday controls people expect through wired headphones: volume control, pause and play, and answering calls. Compatibility is broad — iPhone 17/16/15 families, iPad Pro, MacBook, and a long list of USB-C phones and tablets — with the one caveat the maker flags: it only works with iPad models that actually have a USB-C connector, so check your model first.
Liaoan USB C Headphone: Who It's For
The Liaoan USB C Headphone takes the opposite approach: it does two things and does them cleanly. The 2-in-1 design gives you an IP headphone jack on one side and a Type-C charging jack on the other, so you can charge your USB-C device while you listen to music, watch video, take calls or play games. The spec sheet is explicit that it does not support data transfer — this is an audio-and-power adapter, full stop. If that's all you need, the simplicity is a feature, not a limitation.
Charging is where the Liaoan pulls ahead on paper: it supports a maximum of 100W fast charging through its Type-C jack. The listing frames it as delivering the fastest possible charge to your device, and for anyone with a high-wattage phone or tablet, that higher ceiling is the headline. On the audio side, it uses a highly integrated DAC decoding chip that the maker describes as HiFi decoding with a stable, noise-free conversion and clearer voice calls — useful if you spend a lot of time on calls rather than just music.
Who should buy it? In my opinion, this is for the minimalist: someone who wants a single small adapter for charging and wired listening, values the higher 100W charging rating, and has no interest in OTG, file transfer or USB accessories. It's listed in orange and covers a wide spread of USB-C devices, including the recent iPhone 17/16/15 families, iPad Air/Pro, and a range of Galaxy and LG phones. Who should skip it? Anyone who needs to move files, connect a USB stick, mic, keyboard or card reader — the Liaoan simply can't do it. And if your priority is maximum charging speed, note the INVERSE NET tops out lower at 60W.
Side-by-Side: Which Should You Choose?
• Best for maximum charging speed → Liaoan USB C Headphone: 100W versus the INVERSE NET's 60W (20V/3A).
• Best for versatility → INVERSE NET USB C: three ports (USB OTG + 3.5mm + 60W PD) that work simultaneously.
• Best for straightforward charge-and-listen → Liaoan USB C Headphone: a true 2-in-1 with nothing extra to configure.
• Best for wired headphone controls → INVERSE NET USB C: volume control, pause/play and call answering through the DAC path.
• Best for high-res audio claims → INVERSE NET USB C: DAC rated up to 24bit/96kHz; the Liaoan leans on HiFi decoding with stable, noise-free conversion.
• Best for travel light → Liaoan USB C Headphone: two ports, one job, less to lose.
• Best for desk and camera work → INVERSE NET USB C: its OTG port is built for exactly that kind of accessory swapping.
In my opinion, the INVERSE NET USB C is the smarter buy for most people, because it covers audio, fast charging and USB accessories in one tiny body — the kind of flexibility you notice the moment you need it. I'd only steer you to the Liaoan USB C Headphone if your single priority is the higher 100W charging ceiling and you genuinely never need data transfer or OTG. If you're unsure, ask yourself one question: do you ever plug anything other than headphones into your phone? If yes, the INVERSE NET wins. Either way, check the current price on Amazon before you decide, since that's the one thing this spec comparison can't tell you.
how to charge headphones faster
Charging speed depends on the adapter and the cable, not the headphones themselves. The Liaoan USB C Headphone supports up to 100W fast charging through its Type-C jack, while the INVERSE NET USB C supports up to 60W (20V/3A) PD — so with a matching charger and cable, the Liaoan's ceiling is higher.
how to charge headphones
With either adapter you plug your charger into the adapter's charging port and the adapter into your USB-C device, then connect your headphones to the audio jack. The INVERSE NET uses a 3.5mm headphone jack, while the Liaoan uses an IP headphone jack. Both let you charge and listen at the same time.
how to fast charge bose headphones
These adapters charge the device you plug them into, not the headphones directly — the headphones connect through the audio jack. So to fast charge a phone or tablet while using wired headphones, plug your fast charger into the adapter's PD or Type-C port. The INVERSE NET maxes at 60W and the Liaoan at 100W.
is fast charging bad for headphones
Neither listing suggests that. Here the fast charging applies to your phone or tablet through the adapter's charging port, not to the headphones, which connect via the audio jack. Both adapters are designed to let you charge and listen simultaneously, so fast charging isn't a concern for the headphones in this setup.
