If you want maximum battery life and over-ear comfort for long listening sessions, choose Ulacici Active Noise Cancelling; if you need a pocket-size earbud with a smart touchscreen case, higher waterproofing and app-free EQ control, choose ZYHKON Earbuds.
• Ulacici's biggest strength: Hybrid noise cancellation in an over-ear design with a claimed 60 hours of playtime, multipoint pairing for two devices at once, and a wired USB-C/3.5mm fallback when Bluetooth isn't an option.
• Ulacici's biggest trade-off: It's a full-size over-ear headset. No waterproofing rating, no touch controls, and it lives in a bag rather than a pocket.
• ZYHKON's biggest strength: A feature-dense earbud package — 38dB hybrid ANC with ENC call filtering, a touchscreen charging case that controls playback without your phone, 5 EQ modes, IPX7 waterproofing, and Bluetooth 5.4.
• ZYHKON's biggest trade-off: Per-charge battery is short (6 hours average, 6–8 hours claimed), so the 48-hour figure depends entirely on carrying the case. In-ear fit also isn't for everyone.
• Who each pick is for: Ulacici suits desk workers, travelers and long-session listeners who want big cups and marathon battery. ZYHKON suits commuters, gym-goers and anyone who wants maximum control from the smallest possible package.
The Ulacici U30 is a classic over-ear Bluetooth headphone built around one idea: keep the noise out and keep going. It uses hybrid noise cancellation — meaning the system samples noise from more than one point rather than relying on a single microphone — and pairs that with a 35-ohm dynamic driver covering the standard 20Hz–20,000Hz range. That's a conventional, well-understood audio setup, and the over-ear enclosure in faux leather is the kind of design that spreads pressure across the head instead of pressing into the ear canal.
The feature that stands out most in the specs is battery life. Ulacici rates it at 60 hours of playtime, which is a genuinely different category from most earbuds. Add multipoint connection — staying linked to two Bluetooth devices at once — and you get a headphone that's built for switching between a laptop and a phone without re-pairing. There's also an ANC switch indicator so you can see at a glance whether cancellation is on, and media controls for volume, track skipping and playback. If Bluetooth isn't available, a 3.5mm audio interface and USB-C charging give you a wired path, which matters on planes and older equipment. Bluetooth 5.2 with a 33-foot range covers a normal room.
Buy it if you work at a desk, take long flights or trains, or just want to put something on and forget about charging for days. The over-ear cups and 60-hour rating are the whole argument here.
Skip it if you need earbuds for the gym or running. There's no waterproofing rating, no in-ear seal, and it's simply too big to carry in a pocket.
The ZYHKON Z9pro is the opposite philosophy: compress as much control as possible into something you can lose in a jacket pocket. The headline is the touchscreen charging case, and it's not a gimmick spec — it lets you adjust volume, change tracks, answer calls, toggle ANC or Transparency Mode, set alarms and locate the earbuds without touching your phone. That's a real convenience on a packed train or mid-run.
The noise cancellation here is rated at up to 38dB of ambient noise reduction using hybrid ANC, plus ENC that filters out roughly 90% of background voices on calls. Those are the numbers that matter if you take meetings from a café or an open office. Sound comes from 14.2mm dynamic drivers with five EQ presets — Standard, Rock, Jazz, Pop and Classic — switchable straight from the case, so no app is required. Battery is 6 hours average per charge, extending to 48 hours total with the case, and the display shows real-time levels for both the buds and the case so you're not guessing. IPX7 waterproofing means sweat, rain and splashes are not a problem, and three sizes of silicone tips (S/M/L) help you find a seal. Bluetooth 5.4 handles pairing and stability, with a 15-meter range and broad iOS/Android compatibility. ZYHKON also lists a 24-month warranty.
Buy it if you commute, train, or want ANC and call clarity in a tiny package with controls that don't require your phone.
Skip it if you hate in-ear tips, want a single charge to last a week of heavy use, or prefer physical buttons over touch gestures.
• Best for battery life → Ulacici Active Noise Cancelling. 60 hours rated on the headphone itself versus 6 hours average per charge on the ZYHKON buds.
• Best for travel convenience → ZYHKON Earbuds. Charging case plus touchscreen controls means one small object covers power, playback and settings.
• Best for noisy calls → ZYHKON Earbuds. ENC is specifically built to filter background voices; Ulacici's sheet lists noise cancellation but no call-specific filtering claim.
• Best for workouts and rain → ZYHKON Earbuds. IPX7 protection and a secure in-ear fit; Ulacici has no waterproofing rating and an over-ear frame.
• Best for desk and long-session comfort → Ulacici Active Noise Cancelling. Over-ear faux-leather cups and no ear-canal pressure.
• Best for switching between laptop and phone → Ulacici Active Noise Cancelling. Multipoint keeps two devices connected simultaneously; ZYHKON relies on one-tap auto-connect to one device at a time.
• Best for wired fallback → Ulacici Active Noise Cancelling. It has both a 3.5mm audio interface and USB-C; the ZYHKON has no jack at all.
• Best for tuning your sound → ZYHKON Earbuds. Five EQ presets on the case versus a fixed tuning on the Ulacici.
My Verdict
Both use hybrid active noise cancellation, so they're working from the same principle. ZYHKON quantifies it at up to 38dB and adds ENC for calls. Ulacici doesn't publish a dB figure, but its over-ear cups physically block sound on top of the ANC. In my opinion, the over-ear seal gives Ulacici an edge for steady low-frequency noise like engines.
Ulacici rates its headphone at 60 hours of playtime on a charge. ZYHKON lists 6 hours average per charge, extending to 48 hours total when you count recharges from the touchscreen case. If you want to charge rarely, Ulacici wins; if you're fine docking the buds, ZYHKON covers a long trip.
Yes — they carry an IPX7 waterproof rating, which covers sweat, rain and splashes, and the three silicone tip sizes help you get a stable fit. The Ulacici headphone has no waterproofing rating listed, so I'd keep it out of heavy rain and away from sweaty workouts.
That depends on which specs you actually use, so check the current price on Amazon before deciding. If you want battery and over-ear comfort, the Ulacici earns its keep. If you want a touchscreen case, EQ modes, IPX7 and call filtering in a pocket-size package, the ZYHKON packs more features per gram.
