How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a touchscreen case that doubles as your on-earbud control hub and a simpler everyday listening setup, choose ZYHKON Earbuds; if you need maximum battery life, hi-res LDAC audio and a rugged waterproof build for training and travel, choose TOZO NC20.
• ZYHKON Earbuds — biggest strength: A multifunctional touchscreen charging station plus five EQ modes and 14.2mm drivers make it the more tactile, hands-on pick for casual listeners who like fiddling with settings directly on the case.
• ZYHKON Earbuds — biggest trade-off: The spec sheet doesn't quote a battery figure at all, and it sticks with Bluetooth 5.4 rather than the newer 6.0 in the TOZO, so heavy travelers have less to go on for endurance.
• TOZO NC20 — biggest strength: Up to 80 hours of total playtime (ANC off), LDAC Hi-Res decoding, IPX8 waterproofing and dual-device Bluetooth 6.0 — a lot of endurance and audio pedigree in one package.
• TOZO NC20 — biggest trade-off: Almost everything runs through the TOZO app (in-ear detection, 32 EQ presets), so if you dislike app-dependent earbuds, the experience is less self-contained.
• Pick ZYHKON Earbuds if you want on-case controls, adaptive ANC/ENC for calls, and a no-fuss one-tap pairing routine.
• Pick TOZO NC20 if you want the longest runtime, hi-res audio, and a waterproof shell for workouts, commutes and long trips.
The ZYHKON Earbuds are built around convenience you can literally tap. The standout design choice is the multifunctional touchscreen charging station — instead of digging into a phone app, you interact with the case itself. Paired with five EQ modes (Standard, Classical, Jazz, Rock and Pop), that makes these earbuds feel like a self-contained little audio gadget rather than a phone accessory.
On the sound side, ZYHKON uses 14.2mm dynamic drivers, which is a relatively large driver for in-ear buds and generally points to fuller bass and a wider soundstage. The tuning is flexible rather than fixed: you can flip between EQ presets to match acoustic tracks, jazz, or high-energy pop without opening an app. Bluetooth 5.4 handles the connection, with one-tap smart pairing and instant auto-reconnect once you've paired the first time — handy if you switch between commuting, the gym and meetings.
Noise handling is a dual approach: hybrid ANC to knock down low-frequency rumble and crowd chatter, plus ENC that specifically targets voice pickup so callers hear you more clearly in cafés, on transit, or in wind. If your priority is clear calls and an easy, tactile control scheme, this is the stronger fit. Skip it if you need a documented all-day battery number or hi-res codec support — the spec sheet simply doesn't offer those, so buyers who care most about endurance and lossless-grade audio should look elsewhere.
The TOZO NC20 is the endurance-and-audio-spec pick. Its headline number is up to 80 hours of total playback with ANC off, dropping to 12.5 hours in the buds and 63 hours total with ANC on. A built-in LED power display on the case keeps the remaining charge visible, which reduces the "are these about to die?" anxiety that plagues cheap earbuds.
Audio is where TOZO leans hardest. LDAC Hi-Res wireless decoding supports higher-resolution streaming, and a custom 12mm driver with a Super DLC diaphragm plus dual magnets is designed for clear highs and distortion-free bass. Where ZYHKON gives you five EQ modes on the case, TOZO gives you over 32 EQ presets through the TOZO App, plus thousands of user-shared settings — far more granular, but app-dependent.
The rest of the feature list is travel- and workout-oriented: adaptive hybrid ANC for traffic and ambient noise, Bluetooth 6.0 with dual-device pairing so you can switch between a phone and laptop without re-pairing, smart in-ear detection that pauses audio when you remove a bud, and an IPX8 waterproof rating with HydroGuard protection against sweat and rain. Each bud weighs just 3.7g, and the package includes a wireless charging case, USB-C cable and eartips. Buy these if you want maximum runtime, hi-res audio and durability. Skip them if you'd rather not manage settings through an app.
• Best for battery life → TOZO NC20. Up to 80 hours total (ANC off) and 63 hours with ANC on is the clear endurance winner.
• Best for on-device controls → ZYHKON Earbuds. The multifunctional touchscreen case means you adjust sound without pulling out your phone.
• Best for hi-res audio → TOZO NC20. LDAC decoding and a Super DLC diaphragm driver target detail and clarity.
• Best for EQ flexibility → TOZO NC20. 32+ app presets beat ZYHKON's five on-case modes for sheer choice, though ZYHKON's are easier to reach.
• Best for workouts and rain → TOZO NC20. IPX8 waterproofing plus HydroGuard is the more rugged spec.
• Best for call clarity in noisy places → ZYHKON Earbuds. Dedicated ENC voice isolation targets human speech in cafés, transit and wind.
• Best for multi-device users → TOZO NC20. Bluetooth 6.0 with dual-device switching is more convenient than ZYHKON's Bluetooth 5.4 single-flow approach.
• Best for a simpler, app-free routine → ZYHKON Earbuds. One-tap pairing, auto-reconnect and case-based controls keep things self-contained.
In my opinion, the TOZO NC20 is the safer buy for most people. The 80-hour total playtime, LDAC hi-res audio, IPX8 waterproofing and dual-device Bluetooth 6.0 cover the widest range of real-world needs — travel, workouts, work calls and long listening sessions. I'd only steer you to the ZYHKON Earbuds if the touchscreen case and its five EQ modes genuinely appeal to you and you prefer a setup that doesn't lean on a companion app. Check the current price on Amazon for both before deciding, since that's the one variable that can flip this call.
