How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want one small adapter that adds a 3.5mm headphone jack, a 60W PD fast charging port and a USB OTG data port all at once, choose MTIQHS 3-in-1; if you need to run USB-C headphones and a charger at the same time, choose Bawanfa Plus USB-C.
• MTIQHS 3-in-1 — biggest strength: three genuinely different ports in one body — 3.5mm audio, 60W PD charging and a USB OTG data port for flash drives, keyboards and more.
• MTIQHS 3-in-1 — biggest trade-off: it only speaks USB-C. Lightning iPhones are out, and the OTG port is for data and peripherals, not for a second pair of headphones.
• Bawanfa Plus USB-C — biggest strength: it splits your single USB-C socket into a 60W PD charging port plus two separate audio outputs — one USB-C jack and one 3.5mm jack — so charging and listening stop competing.
• Bawanfa Plus USB-C — biggest trade-off: only one audio jack works at a time, and there's no OTG data port, so no flash drives or USB peripherals.
• Who MTIQHS 3-in-1 is for: anyone on a USB-C phone, tablet or laptop who wants audio, charging and file transfer from one tiny dongle.
• Who Bawanfa Plus USB-C is for: USB-C headphone owners who are tired of picking between sound and battery.
The MTIQHS 3-in-1 is the more versatile of the two on paper, because the third port isn't just another audio jack — it's a USB OTG port. That means the same little white adapter that gives your USB-C phone a headphone jack also lets you plug in a flash drive, a USB hub, a keyboard and mouse, a USB microphone, a digital camera, or even an electric piano. The stated transfer rate goes up to 480Mbps, which is plenty for documents, photos and music files. It's a travel-friendly, do-everything brick rather than a one-trick dongle.
On the charging side, it handles up to 60W (20V/3A) over USB-C PD, with a tin-plated pure copper conductor inside. In practice, that's the kind of headroom that lets a laptop, tablet or phone pull serious power while you're still listening through the 3.5mm jack. The audio path uses a built-in high-resolution DAC chip rated up to 24bit/96kHz, and it supports volume control, pause and play, so calls and music behave normally. Plug and play, no app needed. It's also tiny — about 4.7 x 1.97 x 0.35 inches and roughly 5 grams — so it disappears in a pocket or bag.
Who should buy it: USB-C phone, iPad Pro, MacBook, Galaxy or Pixel owners who want one adapter for audio, fast charging and USB peripherals, and who value the 24bit/96kHz audio ceiling and a 2-year manufacturer warranty. Who should skip it: anyone still on a Lightning iPhone (it simply isn't compatible), and anyone whose main goal is to plug in USB-C headphones — this adapter's audio output is 3.5mm, so USB-C-headphone users should look at the other option.
The Bawanfa Plus USB-C approaches the same problem from the opposite direction. It turns one USB-C port into three: a 60W PD fast charging port, a USB-C audio jack, and a standard 3.5mm audio jack. That layout is aimed squarely at people who own USB-C headphones — the kind with no 3.5mm plug at all — and who are frustrated by the fact that plugging them in normally means giving up their charging port. Here, you get both. Volume control still works while charging, and the built-in charging chip is there to keep power delivery stable and safe.
Its audio chip is rated for 24-bit/48kHz high-resolution output with active noise cancellation, which is a slightly lower sample-rate ceiling than the MTIQHS adapter but still well into high-fidelity territory for everyday music, calls, movies and gaming. The design is a compact, sturdy integrated unit — no driver, no app, just plug and play — and it's pocket-sized for commutes and travel. Compatibility covers USB-C phones and tablets including iPhone 17/16/15 Pro Max/Pro/Plus, Galaxy S23 through S21 and Note 20/10 series, iPad mini 6, iPad Pro 2021/2020, iPad Air 5/4, iPad 2022 and MacBook Pro/Air. It also carries a 2-year warranty.
Two things to know before buying. First, the USB-C headphone jack and the 3.5mm jack cannot be used at the same time — it's one or the other. Second, your charger and cable need to support the PD fast-charging protocol for the 60W rating to actually mean anything. Who should buy it: USB-C headphone owners, and anyone who wants a single dongle that keeps both audio formats available without sacrificing charging. Who should skip it: people who need OTG data transfer, since this adapter has no data port.
• Best for charging speed headroom → a tie. Both top out at 60W PD (20V/3A), so fast charging is genuinely comparable on paper.
• Best for USB-C headphones → Bawanfa Plus USB-C. It has a dedicated USB-C audio jack; the MTIQHS adapter's audio output is 3.5mm only.
• Best for 3.5mm headphone users → MTIQHS 3-in-1. Traditional wired headphones plug straight in, with volume, pause and play support.
• Best for data and peripherals → MTIQHS 3-in-1. Only it offers a USB OTG port for flash drives, keyboards, mice and USB cameras, at up to 480Mbps.
• Best audio resolution figure → MTIQHS 3-in-1, at up to 24bit/96kHz versus 24-bit/48kHz on the Bawanfa Plus.
• Best for keeping both audio formats open → Bawanfa Plus USB-C, though remember only one jack works at a time.
• Best for the smallest, simplest carry → Bawanfa Plus USB-C, given its ultra-compact integrated build.
• Best for Lightning iPhones → neither. Both are USB-C only.
In my opinion, the MTIQHS 3-in-1 is the adapter I'd buy for most people, because the OTG port makes it useful far beyond audio — it's a charger, a headphone jack and a file-transfer tool in one roughly 5-gram package, and its 24bit/96kHz audio ceiling edges out the alternative. I'd pick the Bawanfa Plus USB-C instead if I owned USB-C headphones, since that's the one job MTIQHS can't do. Both are USB-C-only, so check that your phone or tablet qualifies before anything else — and check the current price on Amazon before you commit, since value depends on what you're paying today.
How to charge headphones faster
Fast charging depends on the whole chain, not just the adapter. Both of these pass up to 60W PD, but Bawanfa Plus explicitly notes that your charger plug and cable must also support the PD fast-charging protocol, or you won't get the benefit. Match a PD-rated charger and cable to a PD-rated adapter for the quickest result.
How to charge headphones
With either adapter, you connect your USB-C device, plug a charger into the adapter's charging port, and your headphones or earbuds charge as normal. On the Bawanfa Plus USB-C you can charge and listen at the same time through one audio jack; on the MTIQHS 3-in-1 you can charge while listening through the 3.5mm jack, and it also passes data.
Is fast charging bad for headphones
The PD fast-charging standard is designed to negotiate power safely, and both adapters include protection — Bawanfa Plus cites a built-in charging chip for stability and safety, while MTIQHS uses a tin-plated pure copper conductor. Charging speed is negotiated with your device, so the adapter won't force more power than the device accepts.
How to fast charge Bose headphones
The same rule applies to any brand, including Bose: the charger, the cable and the adapter all need to support PD fast charging. Both of these adapters are rated to 60W PD, so if your Bose headphones support fast charging and you pair them with a PD charger and cable, the adapter won't be the bottleneck.
