• FIO MOTUS biggest strength: A complete listening package — Bluetooth 5.4, active noise cancelling, 30mm dynamic drivers, and up to 55 hours of playtime in one foldable on-ear unit.
• FIO MOTUS biggest trade-off: It's an on-ear design in plastic, so it's a lifestyle headphone rather than a dedicated audiophile component, and its fullest wired potential depends on using the included Type-C audio cable.
• YINYOO USB C biggest strength: A CX31993 + MAX97220 dual-chip DAC dongle rated for 32bit/384kHz decoding, paired with an 8-strand single crystal copper silver-plated IEM cable.
• YINYOO USB C biggest trade-off: It makes no sound on its own — it needs your existing wired headphones, and its real benefit only shows up with lossless sources and decent IEMs.
• Pick FIO MOTUS if you want one device that handles commuting, calls and travel without wires.
• Pick YINYOO USB C if you already own good wired IEMs and want to squeeze hi-res detail out of a USB-C or USB-A device.
The FIO MOTUS FM30 is built around convenience. It's an on-ear wireless headphone with Bluetooth 5.4, a 10-meter wireless range, and multipoint connection for two devices at once — which is genuinely useful if you're bouncing between a laptop and a phone during a workday. The button controls and dual microphone cover the basics for calls and voice commands, and the 30mm dynamic drivers with a 20Hz–40,000Hz frequency range point to a tuning aimed at strong bass and detailed upper frequencies.
The headline feature is the combination of active noise cancelling and up to 55 hours of playtime. Noise cancelling here is described as using both feed-forward and feedback technology, which is the standard dual-microphone approach for reducing steady background noise. That combination — ANC plus long battery — is exactly what long-haul flights, open-plan offices and train commutes demand. It's also foldable and lightweight at 0.28 kg, and it ships with a protective case, a Type-C audio cable, a charging cable and a manual, so it's ready to travel out of the box.
YINYOO USB C: Who It's For
The YINYOO CCZ CM01 is not a headphone at all — it's a small adapter that sits between a digital source and your wired earphones. Inside are two DAC chips, the CX31993 and the MAX97220, which together handle digital-to-analog conversion at up to 32bit/384kHz with the aim of zero-loss output. YINYOO publishes some concrete numbers: SNR above 124dB, THD+N at 1kHz of -95dB, and 63mW of output power at 32Ω. Those figures describe a clean, low-distortion signal that can drive most in-ear monitors without strain, and the listing states it carries Hi Res Gold Label certification.
The supplied cable is worth noting on its own. It's an 8-strand single crystal copper silver-plated IEM cable, and the design logic is sound: copper contributes weight and body in the low and mid frequencies, while silver plating sharpens high-frequency detail. The result, as YINYOO frames it, is a wider soundstage with low distortion. Physically it's tiny — 125mm by 11mm and just 8.5g — and it comes with both USB-C and USB-A interfaces, so it works with USB-C iPhones, iPads, MacBooks, Android phones, laptops, desktops and car stereos.
Who should buy it: anyone with a phone or laptop that dropped the 3.5mm jack, plus a pair of wired IEMs they actually like, and a lossless streaming habit. It's also a sensible pick for calls, livestreams and content creation where clean audio capture matters. Who should skip it: if you don't own wired headphones, or you only stream compressed audio over Bluetooth, this dongle has nothing to work with — it's a link in a chain, not a standalone product.
Side-by-Side: Which Should You Choose?
• Best for all-in-one listening → FIO MOTUS On-Ear Headphones. Wireless, ANC, mic and 55-hour battery in one box; the YINYOO needs a source and your own earphones.
• Best for battery life → FIO MOTUS On-Ear Headphones. Up to 55 hours is the number to beat here; the dongle has no battery and draws from your device.
• Best for travel → FIO MOTUS On-Ear Headphones. Foldable, 0.28 kg, protective case included, and ANC to cut engine and cabin drone.
• Best for existing IEM owners → YINYOO USB C. If you already love your wired in-ears, the CM01 cable and DAC upgrade them for a USB-C or USB-A world.
• Best for calls and meetings → FIO MOTUS On-Ear Headphones. Dual microphones and button controls make it the simpler everyday headset.
• Best for pocketability → YINYOO USB C. At 8.5g it disappears into a pocket, while the FM30 is a full-size on-ear headphone.
• Best for wide device compatibility → YINYOO USB C. USB-C plus USB-A covers iPhones, iPads, MacBooks, Android, desktops and car stereos.
In my opinion, these two don't really compete — they solve different problems, so the right answer depends on what's missing from your setup. If you want one product that replaces everything, I'd buy the FIO MOTUS On-Ear Headphones: ANC, 55 hours, multipoint and a folding travel build cover the most ground for the most people. I'd only choose the YINYOO USB C if you already own wired IEMs you trust and your priority is hi-res lossless decoding from a jack-less device. If that's you, the CM01's dual DAC chips and copper-silver cable make it the more interesting upgrade.
what is hi res headphones
Hi-res headphones are headphones designed to reproduce a wider frequency range than standard audio gear — broadly, the extended detail above and below what CD-quality playback covers. The FIO MOTUS FM30 lists a 20Hz–40,000Hz range, which is wider than the roughly 20Hz–20,000Hz most people hear, and is the kind of spec marketed under the hi-res banner.
what is hi res audio headphones
Hi-res audio is the source material — high-resolution files or streams with more data than a standard compressed track — while hi-res headphones are the playback end of that chain. The YINYOO USB C sits on the source side: its dual DAC chips decode up to 32bit/384kHz, and the listing notes Hi Res Gold Label certification.
what are hi res headphones
Simply put, they're headphones or audio components built to handle high-resolution audio without throwing detail away. The FM30 handles it with 30mm dynamic drivers and a 20Hz–40,000Hz range; the CCZ CM01 handles it by converting digital to analog with SNR above 124dB and THD+N of -95dB at 1kHz.
which headphones support hi res lossless
Support requires both a hi-res-capable source and a playback device, and the two products here cover different halves. The YINYOO USB C supplies the hi-res lossless decoding via its CX31993 and MAX97220 chips, and any wired IEM you plug in becomes the headphone half of that chain. The FM30 is a wireless headphone that also accepts a wired Type-C audio connection, which is the path to its highest-quality playback.
