If you want a pair of over-ear headphones built for marathon listening sessions with hi-res wired flexibility, choose 1Mii Y8; if you need pocket-size earbuds that stream hi-res audio wirelessly over LDAC, choose TOZO NC20.
• 1Mii Y8 biggest strength: Over-ear comfort with 75 hours of playtime, a 40kHz-capable dynamic driver, and a 3.5mm jack that lets you go fully wired when you want to.
• 1Mii Y8 biggest trade-off: It's a full-size over-ear design — bulky for a pocket, and it relies on button/app controls rather than touch gestures.
• TOZO NC20 biggest strength: True wireless earbuds with LDAC hi-res streaming, adaptive hybrid ANC, dual-device pairing and an IPX8 waterproof rating.
• TOZO NC20 biggest trade-off: In-ear fit depends heavily on ear-tip seal, and there's no wired jack — it's wireless only.
• Pick 1Mii Y8 if you want one pair for flights, home office and long workweeks without charging anxiety.
• Pick TOZO NC20 if you want compact, gym-and-commute earbuds with wireless hi-res codec support and automatic in-ear detection.
The 1Mii Y8 is the "one pair that covers everything indoors and on the plane" option. It's an over-ear design with active noise cancellation aimed at low and mid-range noise — the drone of airplane engines, the hum of an office — so it's built to help you settle into music or work rather than fight every sound around you. The ear cushions use protein leather over memory foam, and the headband is ergonomic, which matters when a headphone is meant for all-day wear.
What stands out on paper is the combination of battery and connection flexibility. 75 hours of average battery life is a genuinely long runway — the kind of figure that means you can leave the cable at home for a week of workdays and travel. And when the battery does run down, you're not stuck: there's a 3.5mm jack and an included AUX cable, so the Y8 keeps working as a wired headphone. For anyone who has ever been stranded mid-flight with a dead wireless headphone, that's a real safety net.
Who should skip it? Anyone who wants earbuds. The Y8 is over-ear only, it's the heavier of the two by nature, and if your priority is something that disappears into a jeans pocket, this isn't it. It's also the wrong pick if you specifically want touch controls — the Y8 runs on buttons and the app.
TOZO NC20: Who It's For
The TOZO NC20 takes the opposite approach: maximum portability without giving up hi-res ambitions. These are true wireless in-ear buds, and the headline feature is wireless hi-res — they support Hi-Res Audio wireless with LDAC, which transmits roughly three times more data than standard Bluetooth. For anyone who has wondered which headphones support hi-res lossless, the answer in this matchup is nuanced: the NC20's LDAC path is the wireless hi-res route, and it's the more convenient one for phone-first listening.
The hardware backs it up. A custom 12mm driver with a Super DLC diaphragm and dual magnets is tuned for clear highs and controlled, distortion-free bass, and the frequency range runs from 12Hz to 40kHz — noticeably deeper at the bottom than the Y8's 20Hz floor. The enclosure is ABS plastic, which keeps things light: at 3.7g per earbud, TOZO is clearly designing for a nearly weightless feel with soft silicone tips that stay put across different ear shapes.
The ANC is adaptive hybrid, adjusting in real time to your surroundings and blocking a large share of traffic and conversation noise. There's in-ear detection too — enable it in the app and the buds play when you put them in, pause when you take them out, and drop into adaptive ANC automatically. Dual-device pairing over Bluetooth 6.0 means you can stay connected to a phone and a laptop at once and switch between them. The app carries 32 EQ presets plus a large library of user-shared EQ settings, and there's personalized tuning that adapts to your hearing profile.
Two practical details deserve a mention. First, IPX8 waterproofing with a sealed acoustic chamber and nano membrane — that's a meaningful durability edge over an over-ear headphone for workouts, rain and heavy sweat. Second, the wireless charging case with a battery status display, and 80 hours of average battery life across the system.
Side-by-Side: Which Should You Choose?
• Best for long-haul battery life → 1Mii Y8 (75 hours per charge, plus a wired fallback).
• Best for total system playtime → TOZO NC20 (80 hours with the charging case).
• Best for hi-res wireless streaming → TOZO NC20 (LDAC support).
• Best for wired hi-res listening → 1Mii Y8 (3.5mm jack and included AUX cable).
• Best for travel and flights → 1Mii Y8 (over-ear comfort, ANC tuned for engine drone).
• Best for workouts and wet weather → TOZO NC20 (IPX8 waterproof rating).
• Best for switching between phone and laptop → TOZO NC20 (dual-device pairing over Bluetooth 6.0).
• Best for deep bass extension on paper → TOZO NC20 (12Hz low end vs 20Hz).
• Best for app-based fine-tuning and extras → 1Mii Y8 (custom EQ, sleep sounds, AI voice chat, text translation).
If I were buying for myself, I'd go with the TOZO NC20. In my opinion, the combination of LDAC hi-res wireless, adaptive hybrid ANC, IPX8 waterproofing and dual-device switching covers more of my actual daily listening than a single over-ear pair does — and the 80-hour system battery with a wireless charging case means I'd rarely think about charging. The one thing I'd genuinely miss is the Y8's wired jack. But if your listening happens mostly at a desk, on planes, or in long stretches where comfort and a cable backup matter most, the 1Mii Y8 is the better fit. Neither is "better" in the abstract — they're built for different rooms of your life.
what is hi res headphones
Hi-res headphones are models whose drivers are capable of reproducing frequencies beyond the standard audio range — typically extending toward or past 40kHz. Both products here reach 40kHz, the 1Mii Y8 from 20Hz–40kHz and the TOZO NC20 from 12Hz–40kHz. The extended range matters most when the source and connection can actually carry that detail.
what is hi res audio headphones
It's the same idea framed around the source chain: hi-res audio headphones can accept and reproduce high-resolution audio rather than compressing it down. The TOZO NC20 does this wirelessly via LDAC, which transmits far more data than standard Bluetooth. The 1Mii Y8 does it over its 3.5mm wired connection, where there's no codec bottleneck at all.
what are hi res headphones
Simply put, they're headphones built to handle more of the frequency spectrum than ordinary ones. In this comparison, both qualify: the Y8 with a 20Hz–40kHz dynamic driver and the NC20 with a 12Hz–40kHz DLC driver. What separates them is delivery — wired on the Y8, LDAC wireless on the NC20.
which headphones support hi res lossless
Lossless is really about the wired path, which points to the 1Mii Y8 — its 3.5mm jack and included AUX cable let you bypass Bluetooth entirely. The TOZO NC20 is the wireless hi-res option via LDAC, which is very high quality but still a codec, not a lossless cable. If true lossless matters to you, plan on the Y8 wired.
