• BZINK USB C — biggest strength: a dual-DAC wired adapter (CX31993 + MAX97220) with Hi-Res certification, 32-bit/384kHz decoding, 124dB SNR and enough output for 16–600Ω headphones. It upgrades the headphones you already own rather than replacing them.
• BZINK USB C — biggest trade-off: it is an adapter, not a headphone. You still need a decent wired pair, and it only works through a USB-C (or USB-A, via the included adapter) port — no wireless freedom at all.
• Wentronic Y04 — biggest strength: a self-contained wireless over-ear headphone with ANC, Bluetooth 5.3, a 40mm dynamic driver and 48 hours of playtime — everything you need in one box, no cables, no dongle.
• Wentronic Y04 — biggest trade-off: it tops out at a 20Hz–20,000Hz frequency range, which is standard hi-fi territory rather than extended hi-res territory, and ANC plus Bluetooth inevitably means a different kind of listening than a pure wired chain.
• Who each pick is for: BZINK USB C is for the listener who already owns good wired earphones or over-ears and wants to hear them properly; Wentronic Y04 is for the listener who wants one cable-free, noise-cancelling pair for the ward, the bus and the couch.
The BZINK USB C is, at heart, a tiny amplifier and decoder. The main chipset is a CX31993 paired with a MAX97220 — two dedicated DAC chips rather than the generic audio codec baked into a phone. On paper that shows up as DAC decoding up to 32-bit/384kHz and ADC at 24-bit/96kHz, a signal-to-noise ratio of 124dB at 32Ω, total harmonic distortion plus noise down to -95dB, and 63mW of output into 32Ω. The frequency response spans 20Hz–40kHz and the impedance range is 16–600Ω, which is the interesting number here: it means the same little dongle will happily drive sensitive in-ear monitors and also push high-impedance over-ear headphones that a phone's built-in jack would simply struggle with.
So who should buy it? Anyone who already owns a wired pair they like and feels it sounds thin or quiet straight out of a phone. Nurses are a genuinely good fit here: if you listen on breaks with wired IEMs and want the best hi-res earphones for nurses without carrying a separate player, this is the piece that makes that possible. Who should skip it? Anyone who wants wireless convenience, anyone whose devices are all Lightning or 3.5mm-only, and anyone who does not already own a decent wired headphone — because this adapter cannot fix a bad driver, it can only feed a good one properly.
Wentronic Y04: Who It's For
The Wentronic Y04 is the opposite philosophy: one object, nothing else required. It is a Bluetooth 5.3 over-ear headphone with active noise cancelling, a 40mm dynamic driver, 32Ω impedance and a 20Hz–20,000Hz frequency range. Latency is quoted at 40 milliseconds, which is low enough that audio stays reasonably in sync with video, and the connection is wireless only — there is a 3.5mm jack listed, but the headline feature set is the Bluetooth link. Controls are push-button and built into the earcups, so track skipping, volume and call handling happen on the headphone itself rather than on your phone.
Comfort is clearly the design brief. The over-ear cushions are meant for extended wear, the earpiece shape is circular, and the enclosure is plastic in a Starlight colour with a deliberately minimalist look. The playtime figure is the standout: 48 hours. For someone doing back-to-back twelve-hour shifts, that is the difference between charging every couple of days and never thinking about the battery at all. ANC then does the rest of the work — it blocks ambient noise so you can focus on music or calls, which matters on a loud commuter train, in a shared break room, or in an open-plan office.
Side-by-Side: Which Should You Choose?
• Best for true hi-res playback → BZINK USB C. Hi-Res certification, 32-bit/384kHz decoding and a 20Hz–40kHz response are the specs that matter if hi-res is the goal.
• Best for driving demanding headphones → BZINK USB C. A 16–600Ω impedance range and 63mW at 32Ω mean it handles both sensitive IEMs and hard-to-drive over-ears.
• Best for noise cancelling → Wentronic Y04. Active Noise Cancelling is built in; the BZINK has none, because it is a wired adapter.
• Best for battery life and cable-free use → Wentronic Y04. 48 hours of playtime and Bluetooth 5.3 versus a dongle that draws its power from your phone.
• Best for low-latency wireless video → Wentronic Y04. The 40ms latency figure keeps lip-sync close enough for casual viewing.
• Best for keeping the headphones you already love → BZINK USB C. It upgrades your existing wired pair instead of replacing it, and the USB-A adapter widens it to desktops and consoles.
• Best for a long shift on your feet → Wentronic Y04. Over-ear cushions and push-button controls are built for extended, hands-free wear.
• Best for gaming headphones for nurses → BZINK USB C if you play wired with a good headset, Wentronic Y04 if you want wireless and ANC and can accept the latency trade-off.
In my opinion, the BZINK USB C is the more interesting product for anyone who genuinely cares about hi-res sound, because Hi-Res certification and a dual DAC with real amplification numbers are things the Y04 simply does not claim. But if I am honest about how most nurses actually listen — on a noisy bus, in a shared break room, in ten-minute windows between patients — I would buy the Wentronic Y04. Wireless freedom, active noise cancelling and 48 hours of playtime solve more of the daily problems than a DAC does. Buy the BZINK if you already own great wired earphones and want to hear them at their best; buy the Y04 if you want one pair that just works, everywhere, all week.
FAQ
what is hi res headphones
Hi-res headphones are headphones capable of reproducing audio at a higher resolution than standard CD quality, which usually means supporting higher sampling rates and bit depths and covering an extended frequency range. In this comparison, the BZINK USB C is the hi-res-certified piece, decoding up to 32-bit/384kHz with a 20Hz–40kHz response.
It means the same idea applied to the whole chain: the source file, the decoding hardware and the driver all need to handle high-resolution audio without downsampling. A certified DAC like the BZINK's CX31993 + MAX97220 pair matters because it does the decoding properly before the signal ever reaches your headphones.
what are hi res headphones
They are headphones built and rated for high-resolution playback rather than just standard streaming quality. The Wentronic Y04 is a Bluetooth over-ear with a 20Hz–20,000Hz range — solid hi-fi, but its wireless signal path and frequency ceiling sit outside the strict hi-res definition.
which headphones support hi res lossless
Hi-res lossless playback needs a wired connection from a capable source to a certified DAC and then to the headphone. In this pair, the BZINK USB C is the component that supports that chain at up to 32-bit/384kHz; the Wentronic Y04 is wireless Bluetooth 5.3, which is convenient but not a lossless hi-res path.
