How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired USB-C connection with a four-driver setup and inline control, choose jechan Type C; if you need a truly wireless, sleep-friendly earbud with adaptive noise cancelling and a charging case, choose Rulbovs NE92.
• jechan Type C — biggest strength: A four-driver configuration (dynamic plus balanced armature) with a 10 mm driver and USB-C plug, aimed at immersive bass and clear calls via Environmental Noise Cancellation.
• jechan Type C — biggest trade-off: It is wired, so there is no charging case and no wireless freedom. The inline touch controls and USB-C jack mean your phone or laptop has to be within cable reach.
• Rulbovs NE92 — biggest strength: Adaptive Noise Cancellation, Bluetooth 6.0, and up to 40 hours of total playtime from a charging case, all in a 3-gram-per-bud design built for side sleepers.
• Rulbovs NE92 — biggest trade-off: It is wireless only, so it depends on battery and pairing. There is no jack, and the small in-ear fit is tuned around sleep and light use rather than heavy wired listening.
• Who each is for: Pick jechan Type C if you want plug-and-play wired audio with strong bass and call noise reduction. Pick Rulbovs NE92 if you want cable-free listening, long battery life, and a fit that survives a full night on your side.
The jechan Type C is built around one idea: get a lot of driver hardware into a small, wired shell. The spec sheet lists a four-driver configuration, a 10 mm dynamic driver, and a combination of iron coil and dynamic coil, which is the kind of setup usually associated with deeper bass and more detailed highs than a single basic driver. If you care about low-end punch — electronic music, hip-hop, action-heavy games, or just a subwoofer-style thump in your commute soundtrack — the design here is pointed straight at that.
The second thing that stands out is the USB-C plug. There is no battery to manage, no pairing, no case. You plug in and listen. That makes it a strong fit for a USB-C laptop, a tablet, or a phone without a headphone jack. The inline controls handle volume, track navigation, and calls, so you are not reaching for your screen constantly.
For calls, jechan leans on Environmental Noise Cancellation and a dedicated ENC chip. The sheet describes dynamic noise reduction during calls, meaning the focus is on your voice reaching the other person clearly rather than on blocking the world out for you. The 32-ohm impedance and 20 Hz frequency response suggest it will play fine off a phone or laptop without a separate amp.
Rulbovs NE92: Who It's For
The Rulbovs NE92 is solving a completely different problem: staying in your ear, comfortably, for hours — especially while you sleep. The design is the headline. Each bud weighs about 3 grams, the ear shape is precision-contoured, and the material is ultra-soft silicone. The sheet specifically calls out side sleepers and says the fit stays pressure-free all night. If you have ever woken up because an earbud jammed into your ear, that single design choice is the whole point of this product.
Noise cancelling here is Adaptive Noise Cancellation, and the dual-microphone setup is tuned for calls — the sheet describes it cutting background noise so your voice comes through clearly. That is a different flavour of noise handling than a music-first tuning; it is aimed at sleep, white noise, meditation tracks, and clear voice pickup.
Battery is the other big number. Rulbovs lists up to 10 hours of playback on a single charge and up to 40 hours total with the charging case, with USB-C fast charging bringing them back to full in about an hour. That is a genuinely practical figure for overnight use: you can fall asleep with them and not think about the charger until the next night or later. Bluetooth 6.0 handles the connection, with auto-reconnect when you open the case and a stated range of around 33 feet.
Controls are touch-based — play/pause, skip tracks, answer calls, adjust volume, and voice assistant. The case and kit include a lanyard, the sleep earbuds, a USB-C charging cable, and a user manual. Note the warranty description reads "no," so factor that into how you think about long-term support.
Who should skip it? If you want maximum driver hardware and a wired connection you never have to charge, the NE92's small 6 mm drivers and wireless-only design will feel like a step down. It is built for comfort and endurance, not for bass-head listening.
Side-by-Side: Which Should You Choose?
• Best for battery life → Rulbovs NE92. Up to 10 hours per charge and up to 40 hours with the case beats a wired bud that has no battery at all.
• Best for side sleepers and small ears → Rulbovs NE92. 3 grams per bud, soft silicone, and a contoured shape designed to stay pressure-free.
• Best for plug-and-play, zero-setup listening → jechan Type C. No pairing, no case, no charging — USB-C in, sound out.
• Best for clear calls in noise → jechan Type C if your priority is an ENC chip on a wired connection; Rulbovs NE92 if you want dual-mic noise cutting on a wireless call.
• Best for travel and hiking → Rulbovs NE92. Bluetooth 6.0 with a stated 33-foot range and a charging case fits a pocket far better than a cable.
• Best for working at a USB-C laptop all day → jechan Type C. Inline volume and track controls plus no battery anxiety make it the simpler desk companion.
• Best for a headphone-jack-free phone you still want to use wired → jechan Type C, since the connection is USB-C rather than a 3.5 mm plug.

In my opinion, the deciding factor here is whether you want a cable or a case. If I wanted the most driver hardware for the money and never wanted to think about charging, I would buy the jechan Type C — the four-driver design and USB-C convenience are hard to argue with for desk and commute listening. But if I needed earbuds for sleep, travel, or long wireless sessions, I would buy the Rulbovs NE92, because 3 grams per bud, adaptive noise cancelling, and up to 40 hours of case-backed playtime solve a problem the wired bud simply cannot. Two different jobs, two different picks — and for most people who want in-ear noise cancelling without a cable, the NE92 is the one I would reach for.
FAQ
what are the best in ear noise cancelling earbuds
what are the best over the ear noise cancelling earbuds
"Over the ear" and "in ear" are different categories, and neither product here is an over-ear model — both are in-ear designs. The jechan Type C is an in-ear wired bud with ENC for calls, and the Rulbovs NE92 is an in-ear wireless bud with Adaptive Noise Cancellation. If you specifically want over-ear headphones, you would need to look at a different product type entirely.
No. The jechan Type C is a wired USB-C earbud, so it draws power from whatever it is plugged into and has no battery levels to manage. The Rulbovs NE92 is the opposite — it is fully wireless, with up to 10 hours per charge and up to 40 hours total using its charging case.
The Rulbovs NE92 is the clear pick on design. It weighs about 3 grams per bud, uses ultra-soft silicone, and is contoured specifically so side sleepers stay comfortable overnight. The jechan Type C is a wired metal-housed earbud with no sleep-specific design, so a cable and a firmer shell make it a poor fit for overnight use.
