If you want a wired, lag-free connection for calls and don't want to think about charging, choose jechan Call Noise Cancelling; if you need true hybrid active noise cancelling with a charging case, transparency mode and app-tuned sound, choose TOZO NC9.
• jechan Call Noise Cancelling — biggest strength: a dual-driver setup (dynamic + balanced armature) with dual noise reduction, wired over USB-C, and an in-line control for volume, playback and calls.
• jechan Call Noise Cancelling — biggest trade-off: it's a wired set, so there's no charging case, no Bluetooth freedom, and the noise cancelling is described as call-focused active noise cancellation rather than a full hybrid ANC system.
• TOZO NC9 — biggest strength: hybrid active noise cancelling rated to a 45dB reduction depth, six microphones with ENC for calls, transparency mode, IPX8 water resistance and up to 60 hours of total playtime from the case.
• TOZO NC9 — biggest trade-off: wireless earbuds mean you're dependent on battery and Bluetooth, and this model uses touch plus app controls, which some people find fussier than a simple in-line button.
• Who each pick is for: the jechan set suits anyone who wants a dependable wired connection for calls and everyday listening; the TOZO NC9 suits anyone who wants real ANC, long battery life and app customization for commuting, travel and workouts.
The jechan Call Noise Cancelling is built around two ideas: good sound from two drivers, and clear calls through double-layered noise reduction. On the sound side, jechan pairs a dynamic driver for bass with a balanced armature driver for mids and highs. That's a genuinely different approach from a single-driver earbud — the dynamic side carries the punch, while the balanced armature handles detail and vocal clarity. The frequency range runs 20 Hz to 20,000 Hz with 16 ohm impedance, so it's an easy load for a phone or laptop to drive.
The call side is where the name comes from. jechan describes both active call noise cancellation (to knock down traffic, crowd or office chatter) and physical isolation from the in-ear seal. That combination makes sense for remote work, business calls and commutes — the kind of situations where your voice needs to come through cleanly without you hunting for a quiet room. The in-line control is the practical detail I like here: volume, playback and calls are all a push-button away on the cable, with no app and no pairing step.
Who should buy it? Anyone who values a stable wired connection, wants zero lag (jechan lists audio latency of 0.1 milliseconds), and doesn't want to manage yet another battery. The metal enclosure, tangle-resistant cable and multiple ear tip sizes point to a set meant for long, daily use — walking, running or a full workday.
TOZO NC9: Who It's For
The TOZO NC9 is a much more ambitious product on paper. It's a hybrid active noise cancelling design rated to a maximum reduction depth of 45dB — that's the kind of figure that matters on a plane, a train or a noisy open-plan office. Because it's hybrid, it uses both feedforward and feedback style cancellation rather than relying on the seal alone, and TOZO gives you a transparency mode when you do want to hear announcements, traffic or someone talking to you without pulling the buds out.
Calls get serious treatment too: six microphones with ENC ambient noise reduction, which is the wireless equivalent of what the jechan set does on a wire. Sound comes from 10mm dynamic drivers with TOZO's OrigX Acoustic 2.0 tuning, and the TOZO app opens up 32 EQ options plus a sharing zone where you can post your own EQ preset. If you like fiddling with bass levels and sound style, that's a real advantage over a set with no app at all.
Battery is the headline. TOZO claims up to 60 hours total with ANC off and 40 hours with ANC on, with 14 hours (ANC off) or 10 hours (ANC on) in a single stretch, and roughly 1.5 hours for a full charge. The case has an LED display showing remaining battery, which removes the guessing game. Add IPX8 water resistance, Bluetooth 5.3 with a 20-metre range, and six sizes of replaceable ear caps, and you have a set designed for long days, workouts and travel.
Who should buy it? Commuters, travellers, gym-goers and anyone who wants wireless convenience plus strong ANC, long battery and app-level control. Who should skip it? If you hate charging earbuds, dislike touch controls, or want a guaranteed lag-free wired signal, the wired jechan set is the simpler answer. Note the NC9 lists 60 milliseconds of audio latency versus the jechan's 0.1 milliseconds — for most music and calls that's irrelevant, but competitive gamers who care about sync should weigh it.
• Best for active noise cancelling strength → TOZO NC9. Hybrid ANC with a 45dB reduction depth is a different tier from call-focused cancellation.
• Best for call clarity in noisy places → close call, but the TOZO NC9's six-mic ENC array is the more complete call system; the jechan set counters with active call noise cancellation plus physical isolation.
• Best for latency-free audio and gaming → jechan Call Noise Cancelling. 0.1 milliseconds of latency and a wired USB-C connection beat Bluetooth for sync.
• Best for battery life → TOZO NC9. Up to 60 hours total from the case with ANC off; the jechan set has no battery at all because it's wired.
• Best for workouts and wet weather → TOZO NC9. IPX8 water resistance is the deciding spec here.
• Best for sound customization → TOZO NC9. 32 EQ options via the app versus no app and no EQ on the jechan set.
• Best for simplicity and never charging → jechan Call Noise Cancelling. Plug in, push the in-line button, done.
• Best for staying aware of your surroundings → TOZO NC9. Transparency mode lets ambient sound in on demand.
In my opinion, the TOZO NC9 is the better buy for most people. Hybrid ANC at a 45dB reduction depth, six-mic ENC calls, transparency mode, IPX8, app EQ and up to 60 hours of total playtime cover more real-world situations than any wired set can. I'd only steer you to the jechan Call Noise Cancelling if you specifically want a wired, zero-latency connection for calls and don't want to manage charging — in that niche, its dual-driver design and in-line controls make it the smarter pick.
what are the best in ear noise cancelling earbuds
Based on the specs here, the TOZO NC9 is the stronger in-ear noise cancelling option: hybrid ANC with a 45dB reduction depth, transparency mode, six-mic ENC calls, IPX8 and up to 60 hours total playtime. The jechan Call Noise Cancelling is also in-ear, but its noise cancelling is aimed at calls rather than full hybrid ANC.
what are the best over the ear noise cancelling earbuds
Neither product on this page is an over-ear model — both are in-ear designs. The jechan set is a wired in-ear earbud with a metal enclosure, and the TOZO NC9 is a wireless in-ear earbud with hybrid ANC and a charging case, so if you specifically want over-ear headphones you'll need to look at a different category.
No. The jechan set is wired over USB-C, so it draws power from whatever it's plugged into and has no battery to manage. The TOZO NC9 is the opposite: it's Bluetooth, charges in about 1.5 hours, and gives up to 60 hours of total playtime with ANC off or 40 hours with ANC on.
Both are built for it. The TOZO NC9 uses six microphones with ENC ambient noise reduction and adds hybrid ANC. The jechan set uses active call noise cancellation plus physical isolation from the in-ear seal. If you make calls in genuinely loud places and want the most layers of protection, I'd lean TOZO NC9.
