How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wireless, app-tunable over-ear headphone with active noise cancellation for flights, offices and long listening sessions, choose TOZO Hybrid Active Noise; if you need a wired USB-C in-ear set for clear calls, low-latency listening and passive isolation on a commute, choose jechan Dynamic Balanced Deep.
• TOZO Hybrid Active Noise – biggest strength: True active noise cancellation with a Transparency mode, 60 hours of playtime, Bluetooth 5.3, app-based EQ and a 3.5 mm wired fallback.
• TOZO Hybrid Active Noise – biggest trade-off: It's a 225 g over-ear headphone in a single Pink colorway, and its noise cancelling needs charging — no battery, no ANC.
• jechan Dynamic Balanced Deep – biggest strength: A wired USB-C in-ear with a dual-driver setup, an inline mic with call noise cancelling, and a claimed 0.5 ms latency.
• jechan Dynamic Balanced Deep – biggest trade-off: It's wired-only with no Bluetooth, no app, no battery and only passive isolation — you're tethered to your device.
• Pick TOZO Hybrid Active Noise if you want one headphone for travel, home office and calls with real ANC and battery freedom.
• Pick jechan Dynamic Balanced Deep if you want a plug-and-play wired earbud for calls and low-latency listening without charging anything.
The TOZO Hybrid Active Noise is built around one idea: cut the noise around you without wires. It's an over-ear headphone with 40 mm dynamic drivers, 32 ohm impedance, a 20 kHz frequency response and 115 dB sensitivity, so it's easy to drive from a phone, laptop or tablet. The headline feature is genuine Active Noise Cancellation — the kind that targets steady droning sounds like airplane engines and subway rumble — plus a Transparency Mode so you can hear announcements or a colleague without pulling the headphones off. That combination is what separates it from a passive-isolation design.
Battery is the other pillar. TOZO rates it at 60 hours of average life with a 2-hour charge time over USB-C, which means you can realistically go a week of commuting between charges. Bluetooth 5.3 with a 10-meter range covers the usual desk-to-kitchen wandering, and the 90 ms latency figure is fine for podcasts, meetings and casual video. If you care about sync on fast-paced games, that number is the one to weigh.
Controls are flexible: button and touch on the earcups, plus app control for a custom EQ. There's also a 3.5 mm jack and an included AUX cable, so you can keep using it wired when the battery is flat or on a plane's seat-back system. The 225 g weight is average for an over-ear with ANC — comfortable for long sessions, but not featherweight.
Buy it if you want one pair for flights, open offices, libraries and home study, and you value ANC, battery life and app tuning. Skip it if you want something pocketable, prefer a wired connection by default, or you specifically want an in-ear fit — this is a full-size headphone, and the Pink ABS finish is the only color listed.
The jechan Dynamic Balanced Deep takes the opposite approach. It's a wired in-ear headphone that connects over USB-C — no Bluetooth, no pairing, no charging. You plug it in and it works. The design uses a balanced armature driver with a 20 Hz – 20,000 Hz frequency range, 32 ohm impedance and 102 dB sensitivity, tuned for what jechan describes as dynamic balanced bass and treble with a deep bass emphasis. The metal housing and dark brown finish give it a sturdier feel than the usual plastic bud.
The practical selling point is calls. There's a built-in microphone with call noise cancelling and a passive noise isolation design — the seal in your ear blocks some surrounding noise rather than cancelling it electronically. The inline module handles push-button controls, which is about as simple as headphone controls get. And the latency figure is striking: 0.5 ms. For wired audio that's essentially imperceptible, which matters if you're watching video, gaming or doing anything where lip-sync drift is annoying.
Because it's wired, there's nothing to charge and nothing to run out. At 1.6 ounces it's light enough to forget you're wearing it, and the round in-ear shape is aimed at all-day comfort for work or travel. The trade-offs are real, though: you're tethered to whatever has a USB-C port, there's no app, no EQ customization, no ANC and no wireless range. Passive isolation only does so much on a plane or a noisy train.
Buy it if you make a lot of calls, want zero-latency wired audio, and like the in-ear fit. Skip it if you need wireless freedom, active noise cancelling, or you use a device without USB-C — there's no 3.5 mm option listed.
• Best for noise cancelling → TOZO Hybrid Active Noise. Real ANC plus Transparency Mode beats the jechan's passive isolation for engines and crowd rumble.
• Best for battery life and wireless freedom → TOZO Hybrid Active Noise. 60 hours per charge, Bluetooth 5.3, and a 10-meter range.
• Best for calls in a busy room → jechan Dynamic Balanced Deep. The inline mic with call noise cancelling is the more purpose-built setup for voice.
• Best for lowest latency / video and gaming sync → jechan Dynamic Balanced Deep. 0.5 ms versus 90 ms is a different league.
• Best for travel convenience → it splits. TOZO is better on a plane thanks to ANC and wireless; jechan is better if you want something tiny that never needs charging.
• Best for comfort over long sessions → TOZO Hybrid Active Noise for over-ear cushioning, or jechan if you prefer a light 1.6 oz in-ear.
• Best for customization → TOZO Hybrid Active Noise. The app gives you a custom EQ; the jechan offers button controls only.
• Best for plug-and-play simplicity → jechan Dynamic Balanced Deep. No pairing, no app, no charging routine.
I'd buy the TOZO Hybrid Active Noise for most people. The combination of real active noise cancellation, a Transparency mode, 60 hours of battery, Bluetooth 5.3, app EQ and a 3.5 mm wired backup covers more situations — flights, offices, study, calls, movies — than any single wired earbud can. I'd only steer you to the jechan Dynamic Balanced Deep if your priority is wired, low-latency, mic-forward listening and you don't mind being tethered. For a one-headphone-for-everything buyer, TOZO is the safer call.
Yes. TOZO uses active noise cancellation with a Transparency Mode, which targets steady background noise electronically. The jechan relies on passive isolation from the ear seal, which helps but doesn't cancel sound the same way. For planes, trains and open offices, TOZO has the advantage.
No. They're wired in-ear headphones that connect over USB-C. There's no Bluetooth and no battery, so there's nothing to charge — but you're tethered to your device and need a USB-C port to use them.
The jechan has a dedicated call noise cancelling microphone and inline push-button controls, which makes it the more focused call tool. The TOZO also handles calls over Bluetooth 5.3 and works for meetings, but its strength is the listening and noise-cancelling side.
The TOZO Hybrid Active Noise, since it runs on Bluetooth and also includes a 3.5 mm jack with an AUX cable. The jechan is USB-C wired only, so it can't switch to wireless. Check the current price on Amazon before deciding, since that's the one thing that can tip a close call.
