• TOZO NC9 — biggest strength: Hybrid ANC rated to a 45dB reduction depth, a 6-mic ENC call array, IPX8 waterproofing and 59 hours of total battery life.
• TOZO NC9 — biggest trade-off: No translation features and no touchscreen case; it's a straightforward music-and-calls earbud, and the bundled A1 pair is a lighter, IPX5 companion rather than a second flagship.
• ZYHKON AI Translation Earbuds — biggest strength: Real-time two-way translation across 164 languages with no subscription, plus a touchscreen charging case that controls music, calls and volume.
• ZYHKON AI Translation Earbuds — biggest trade-off: ANC is rated lower at up to 38dB, and the headline battery figure is 48 hours total with 8 hours per charge — less than the NC9.
• Who each pick is for: TOZO NC9 for noise-blocking, all-day wear and wet-weather use; ZYHKON for travelers, students and bilingual conversations who still want decent audio.
The NC9 is built around one idea: shut the world out. TOZO rates its hybrid active noise cancellation at a maximum reduction depth of 45dB, which is the deepest figure in this comparison. Hybrid ANC means the system uses microphones on both the outside and inside of the earbud to catch noise before and after it enters your ear, and that's the design that usually handles steady low-frequency rumble — engine drone, air conditioning, train noise — better than a single-mic setup. There's also a Transparent Mode when you'd rather hear traffic or a barista than block them.
Sound comes from 10mm dynamic drivers paired with TOZO's OrigX Acoustic 2.0 processing, covering a 20Hz–20,000Hz range, with 32 preset EQs adjustable in the app. Calls rely on a 6-microphone array with ENC, which filters background noise so your voice comes through in busy places. For Xbox use, note what's here and what isn't: these are Bluetooth 5.3 in-ear buds with touch controls and no jack. You can pair them to a console that supports Bluetooth audio, but there's no low-latency gaming mode listed and no boom mic — so treat them as earbuds you also use for gaming, not gaming gear.
Battery is the standout: 59 hours average life with the charging case, plus an LED display to show charge status. IPX8 is the highest water-resistance rating here, which matters if you sweat heavily or get caught in rain. Comfort is handled by ergonomic shaping and six sizes of replaceable earcaps.
Buy the NC9 if you want maximum noise cancellation, long battery life, a waterproof build and clear calls. Skip it if you need live translation, a touchscreen case, or a true low-latency wireless setup for competitive console play.
The ZYHKON pair is a different product category wearing the same shape. Its core feature is real-time, two-way translation in 164 languages with no subscription — you download the app, connect once, and translate without monthly fees. ZYHKON quotes a response time under two seconds, which is the difference between a conversation that flows and one that stalls.
The modes are where the thought went. Free Talk Mode handles automatic back-and-forth conversation without tapping your phone. Headset + Phone Mode is the quick two-way option for ordering food or asking directions. There's also Photo Translation, Voice Memo and an AI Chat Mode for language learning and note-taking. For anyone traveling, studying a language, or working with international colleagues, that toolkit is the entire reason to buy these.
The charging case has a touchscreen, and that's more useful than it sounds: you control music, calls, translation functions, volume and alarms from the display instead of digging out your phone. Audio is handled by 14.2mm dynamic drivers — larger than the NC9's 10mm — over a 20Hz–20,000Hz range, with hybrid ANC rated up to 38dB and ENC for calls. Bluetooth 5.4 is the newer version here, which typically means faster pairing and a more stable connection, and it works with both iOS and Android.
Battery is 6–8 hours per charge and up to 48 hours total, which ZYHKON frames around long flights and business trips. The color is blue, the enclosure is plastic with silicone tips, and there's a 2-year warranty listed.
Buy the ZYHKON if translation is a real need and you want solid sound, a smart case and newer Bluetooth alongside it. Skip it if you mainly want the deepest possible noise cancellation and the longest runtime, or if you'd rather not depend on a companion app for the product's main feature.
• Best for noise cancellation → TOZO NC9. 45dB hybrid ANC vs 38dB on the ZYHKON.
• Best for battery life → TOZO NC9. 59 hours total vs 48 hours total on the ZYHKON.
• Best for water resistance → TOZO NC9. IPX8 versus no IP rating listed for the ZYHKON.
• Best for calls in noisy places → TOZO NC9. A 6-mic ENC array is the more elaborate setup on paper.
• Best for travel and language barriers → ZYHKON. 164 languages, real-time two-way translation, no subscription.
• Best for controlling things without your phone → ZYHKON. The touchscreen case handles music, calls, volume and alarms.
• Best for newer connectivity → ZYHKON. Bluetooth 5.4 vs Bluetooth 5.3.
• Best for Xbox use → TOZO NC9, in my opinion. Neither is a gaming headset, but the NC9's longer battery and stronger isolation suit long sessions better; if you'd rather have open-ear or bone-conduction designs for gaming, this pair isn't that — those are a separate category.
In my opinion, most people should buy the TOZO NC9. Deeper hybrid ANC, IPX8 waterproofing, a 6-mic call array and 59 hours of runtime cover the everyday jobs — commuting, workouts, calls, and long Xbox sessions where you want the room to disappear. I'd only switch to the ZYHKON AI Translation Earbuds if translation is something you'll actually use: 164 languages with no subscription, a touchscreen case and Bluetooth 5.4 make it the better tool for travel, study and international work, and its audio hardware is no slouch either. Pick the ZYHKON for the languages, the NC9 for the silence.
Hybrid ANC uses microphones positioned both outside and inside the earbud to detect ambient noise, then generates opposing sound to cancel it. It generally handles a wider range of noise than single-mic ANC. The TOZO NC9 and the ZYHKON both use hybrid ANC, rated to 45dB and 38dB respectively.
ANC stands for Active Noise Cancellation — the earbuds listen to surrounding noise and cancel it electronically rather than just sealing your ear. It's most effective on steady sounds like engines and fans. Both earbuds here include ANC, plus a transparency-style option so you can hear your surroundings.
They're best for noisy commutes, flights, open offices and anywhere you want to lower background sound without raising volume. The NC9's 45dB rating and IPX8 build suit workouts and wet weather too, while the ZYHKON adds translation modes for travel and conversation.
Neither is a dedicated gaming headset — both are in-ear Bluetooth earbuds with no headphone jack and no gaming mode listed. They'll work for audio on a Bluetooth-capable setup, but for competitive play many people prefer low-latency gaming headsets, or open-ear and bone-conduction designs for long sessions.
