If you want to turn a single USB-C port into both a wired headphone jack and a fast-charging passthrough for your phone, choose Xumee USB Type C; if you need actual hi-res earbuds with a built-in DAC, a mic with mute and a wired USB-C connection that just works, choose JVC USB-C Earbuds.
• Xumee USB Type C — biggest strength: it's a 2-in-1 adapter that adds a 3.5mm aux port and 60W PD charging at the same time, with a smart DAC chip for better audio than a plain dongle.
• Xumee USB Type C — biggest trade-off: it's an adapter, not headphones. You still need your own wired headphones, and some newer phones may not support Quick Charge through it.
• JVC USB-C Earbuds — biggest strength: real hi-res audio in the earbuds themselves, thanks to a high-quality D/A converter and a 10mm neodymium driver, plus a 3-button remote with mute.
• JVC USB-C Earbuds — biggest trade-off: it's a single-purpose device. It plays audio and takes calls, but it can't charge your phone while you listen.
• Who each pick is for: go Xumee if you already own good 3.5mm headphones and want to keep charging. Go JVC if you want one cable, one pair of earbuds, and nothing else to carry.
The Xumee adapter solves a very specific modern problem: phones dropped the headphone jack, but your favorite wired headphones didn't. This little dongle splits your USB-C port into a 3.5mm female audio jack and a charging input that supports up to 60W Power Delivery. That means you can listen to music and top up your battery at the same time — something most simple USB-C-to-3.5mm dongles can't do. Inside is a smart DAC chip, and the 3.5mm port works with both CTIA and OMTP headset wiring, so older and newer wired headsets are covered. It also handles mic input and in-line wire controls, so answering calls and pausing tracks with your headset's buttons still works.
Compatibility is broad. Xumee lists iPhone 16 / 15 Pro Max / 15 Pro / 15 Plus / 15, most USB-C Android phones including Galaxy S25, S24, S23, S22, S21 series, Note 20 and Note 10, Google Pixel 8 and 7 XL, iPad Pro, and Huawei Mate and P series devices. It's plug-and-play — no drivers, no setup. At 4.54 g it disappears in a pocket, and the strain-relief design is built to survive repeated bending.
Who should buy it? Anyone with a good pair of wired 3.5mm headphones or IEMs who wants to keep using them on a USB-C phone, and who doesn't want to choose between charging and listening. Who should skip it? If you don't already own wired headphones, this adapter gives you nothing to plug in. Also skip it if you need guaranteed fast charging on a phone that only plays nicely with Quick Charge — Xumee specifically notes that PD wall chargers are the safer bet, and that some newer phones may not support QC through it. One quirk worth knowing: audio can pause when you plug or unplug the charger, because the control chip restarts. Just hit play again.
The JVC HAFR29UC is the other philosophy entirely: everything in one cable. These are wired in-ear earbuds with a USB-C plug on the end, so there's no dongle to lose and no adapter to forget. The headline feature is hi-res audio support, backed by a high-quality D/A converter that JVC says minimizes noise and sound degradation, plus a 10mm neodymium dynamic driver. The frequency range runs 20 Hz to 22,000 Hz at 16 ohm impedance — easy to drive, and the 22 kHz ceiling is exactly the kind of extended range "hi-res" is talking about.
The control story is better than most budget earbuds. A 3-button remote handles volume, mute on/off, and sound mode switching between Flat, Bass, and Clear — handy when you're on a call and want voices to cut through. There's a built-in mic, and the mute button is a genuinely useful touch for meetings. Noise isolation comes from the silicone tips rather than active noise cancellation, so you get passive blocking of surrounding chatter. JVC includes four sizes of earpieces, a 1.2m cable, a small carrying pouch, and a 1-year parts and labor warranty. At 18.14 g they're light enough for long sessions, and they plug straight into a PC, phone, or tablet with no drivers.
Who should buy it? People who want one simple wired setup for music, calls, and video, and who care about hi-res audio without buying a separate DAC or adapter. The three color options and compact pouch make them an easy travel pick. Who should skip it? If you want to charge while you listen, these can't do it — the USB-C port is occupied by the earbuds. And if you already own high-end wired headphones you love, the Xumee route preserves that investment instead of replacing it.
• Best for hi-res listening out of the box → JVC USB-C Earbuds. The dedicated D/A converter and 10mm driver are built for it; nothing extra to buy.
• Best for keeping your own headphones → Xumee USB Type C. It's the bridge for the wired gear you already own, with a Hi-Res DAC chip of its own.
• Best for charging while listening → Xumee USB Type C. Up to 60W PD passthrough is something the JVC earbuds simply don't offer.
• Best for calls and mute → JVC USB-C Earbuds. The 3-button remote with dedicated mute beats a generic in-line control.
• Best for sound tuning → JVC USB-C Earbuds. Flat, Bass, and Clear modes let you adjust on the fly.
• Best for portability and zero setup → JVC USB-C Earbuds. One 1.2m cable, a pouch, four tip sizes, no dongle to misplace.
• Best for mixed devices → Xumee USB Type C. The long compatibility list covers iPhone 15/16, Galaxy, Pixel, iPad Pro, and Huawei in one small part.
• Best if you hate earbuds → Xumee USB Type C. Over-ear and on-ear 3.5mm headphones work fine through it.
In my opinion, the JVC USB-C Earbuds are the better buy for most people asking this question, because they deliver the hi-res audio experience directly — DAC, driver, mic, mute, and sound modes — with nothing else to buy or lose. I'd pick the Xumee USB Type C only if you already own wired headphones you love and you refuse to give up charging while you listen. If your priority is sound quality per dollar and a single tidy cable, go JVC. If your priority is flexibility and keeping your existing gear alive, go Xumee.
what is hi res headphones
Hi-res headphones are built to reproduce a wider frequency range than standard audio gear — in this case up to 22,000 Hz — so fine detail in recordings comes through more clearly. The JVC earbuds qualify through their D/A converter and 10mm driver, while the Xumee adapter's Hi-Res DAC chip brings the same idea to whatever 3.5mm headphones you already own.
what is hi res audio headphones
Hi-res audio refers to playback that preserves more detail than a compressed, downsampled signal. Headphones carrying that label, like the JVC HAFR29UC, pair a capable driver with a clean converter so the extra information actually reaches your ears instead of getting smeared on the way.
what are hi res headphones
They're headphones designed around detail rather than just loudness. In practice that means a proper D/A converter, a decent driver, and a frequency range that extends to about 22 kHz — all things the JVC model lists, and all things the Xumee adapter adds to a wired headset you plug into it.
which headphones support hi res lossless
You need a source, a converter, and a driver that all keep up. The JVC USB-C Earbuds are the self-contained option here, with their built-in D/A converter and USB-C connection. If you'd rather use your own wired headphones, the Xumee USB Type C supplies the Hi-Res DAC stage that many phones' USB-C ports otherwise lack.
