If you want over-ear hi-res listening with active noise cancelling and a huge 48-hour battery, choose Wentronic Y04; if you need pocket-sized earbuds with LDAC hi-res wireless, adaptive ANC and dual-device switching, choose TOZO NC20.
• Wentronic Y04 — biggest strength: Over-ear comfort with 40 mm dynamic drivers, Bluetooth 5.3, ANC and a battery claim of up to 48 hours.
• Wentronic Y04 — biggest trade-off: It's a full-size plastic over-ear headphone, so it's bulkier to carry and its frequency range tops out at the standard 20Hz–20,000Hz rather than the extended range the TOZO reaches.
• TOZO NC20 — biggest strength: LDAC hi-res wireless audio, a wide 12Hz–40kHz range, adaptive hybrid ANC, 6 mics, IPX8 waterproofing and 80 hours of total playtime with the case.
• TOZO NC20 — biggest trade-off: They're in-ear buds, so fit depends on ear tips, and getting the most out of them (EQ presets, in-ear detection) leans on the companion app.
• Pick Wentronic Y04 if: you want one comfortable pair of over-ear headphones for long desk sessions, travel and calls.
• Pick TOZO NC20 if: you want maximum portability plus the hi-res LDAC codec and app-based tuning.
The Wentronic Y04 is a classic over-ear wireless headphone built around comfort and simplicity. The 40 mm dynamic drivers sit inside soft over-ear cushions, which is the kind of design that spreads pressure around your ears instead of pressing into them. For anyone who wears headphones for hours — a full workday at a desk, a long flight, a slow Sunday of podcasts — that over-ear fit is the whole point. The stated 48-hour playtime backs that up: you can plausibly go days between charges without thinking about it.
On the tech side you get Bluetooth 5.3 for a stable, low-latency link, active noise cancelling to pull down ambient noise, and a listed 40 ms audio latency, which matters if you watch video or play games and don't want lip-sync drift. Controls are physical push buttons rather than touch, and there's a 3.5 mm jack if you ever want a wired connection. Impedance is 32 ohm, so they're easy to drive from a phone or laptop.
Who should buy it? In my opinion, the Y04 suits the listener who wants one dependable over-ear pair for home, office and travel and values battery life and physical buttons over app tinkering. Who should skip it? If you want true wireless earbuds you can drop in a pocket, or you specifically want the LDAC hi-res codec and an app with EQ presets, this isn't the design for you — it's a single over-ear headphone, and its range is the conventional 20Hz–20,000Hz.
The TOZO NC20 is a true wireless earbud aimed squarely at people who care about hi-res wireless audio. The headline is LDAC support with Hi-Res Audio Wireless, which transmits substantially more data than a standard Bluetooth link — that's the mechanism behind the extra detail. The claimed frequency range of 12Hz–40kHz goes well beyond what the human ear hears at the top end, and the 12 mm Super DLC diaphragm driver with dual magnets is tuned for clear highs and controlled bass. There's also OrigX Pro processing for a wider sense of space.
Around that core, the NC20 stacks up features: adaptive hybrid ANC that adjusts to your surroundings, 6 mics with AI call handling, in-ear detection that auto-plays and auto-pauses, and dual-device pairing over Bluetooth 6.0 so you can hop between a phone and a laptop. Battery life is listed at 80 hours, presumably counting the charging case, and the case supports wireless charging. IPX8 waterproofing plus a sealed acoustic chamber and nano coating means sweat and rain are less of a worry. At 3.7 g per earbud, they're built for long wear.
Who should buy it? Anyone who wants hi-res codec support, app-based tuning with 32 EQ presets, and buds light enough to forget they're in. Who should skip it? If you dislike in-ear tips, don't want to use an app, or prefer over-ear isolation and physical buttons, the NC20 will feel like the wrong shape — and its fit depends on getting a good tip seal.
• Best for hi-res codec support → TOZO NC20 (LDAC / Hi-Res Audio Wireless; the Y04 uses standard Bluetooth 5.3 with a 20Hz–20,000Hz range).
• Best for battery life → Wentronic Y04 on a single charge basis at a listed 48 hours; TOZO NC20 lists 80 hours with its case.
• Best for long-wear comfort at a desk → Wentronic Y04, thanks to its over-ear cushions and 40 mm drivers.
• Best for portability and workouts → TOZO NC20, with 3.7 g earbuds and IPX8 waterproofing.
• Best for call clarity → TOZO NC20, which lists 6 mics with AI call processing.
• Best for simplicity → Wentronic Y04, with push-button controls, no app required and a 3.5 mm wired option.
• Best for tuning the sound → TOZO NC20, with 32 EQ presets in the TOZO app.
• Best for switching between two devices → TOZO NC20, thanks to Bluetooth 6.0 dual pairing.
If hi-res audio is your priority, I'd buy the TOZO NC20. LDAC support, the 12Hz–40kHz range and the DLC driver are exactly what "hi-res headphones" should mean in 2026, and the app, adaptive ANC, IPX8 rating and dual pairing make it the more future-proof pick for most people. I'd only go with the Wentronic Y04 if over-ear comfort, physical buttons and marathon battery life matter more to you than codec support — that's a legitimate reason, but it's a different priority. In my opinion, the NC20 is the stronger all-rounder for the hi-res listener.
FAQ
what is hi res headphones
what is hi res audio headphones
Hi-res audio refers to audio mastered and delivered at higher-than-CD resolution, and hi-res audio headphones are the gear that can play it back without downsampling it heavily. In practice, that means support for a codec like LDAC, which the TOZO NC20 lists, rather than just any wireless headphone.
what are hi res headphones
They're headphones designed to preserve more of the original recording's detail — wider frequency range, higher data throughput, or both. The TOZO NC20 fits that description with LDAC and a 12Hz–40kHz range, while the Wentronic Y04 focuses on comfort, ANC and a long 48-hour battery instead.
which headphones support hi res lossless
Lossless over wireless depends on the codec and the source device. The TOZO NC20 supports LDAC Hi-Res Audio Wireless, which is the hi-res path here; for true lossless you'd typically need a wired connection, which the Wentronic Y04 offers through its 3.5 mm jack. Whichever you pick, check the current price on Amazon before deciding.
