If you want one pair of earplugs that lets you dial your own noise level up and down all day, choose Loop Switch 2; if you need a wired headset with a microphone for clear phone calls and music with deep bass, choose jechan Call Noise Cancelling. These two products both reduce noise in your ears, but they solve completely different problems. One is a passive hearing-protection tool you wear to control the world around you. The other is a wired set of in-ear headphones built for listening and talking. If you are shopping for in ear noise cancelling earbuds, the honest answer is that they are not really competitors at all — they are two different jobs.
• Loop Switch 2 — biggest strength: Three adjustable noise-reduction modes (Quiet, Engage, Experience) in a single passive earplug, with 20-26 dB SNR of reduction and a manual in-ear dial you can change on the fly.
• Loop Switch 2 — biggest trade-off: It has no electronics, no battery and no microphone, so it is not a listening device. You cannot play music or take a call with it.
• jechan Call Noise Cancelling — biggest strength: Dual-driver Hi-Fi sound (dynamic plus balanced armature) with active call noise cancellation and a USB Type-C wired connection with an inline mic and controls.
• jechan Call Noise Cancelling — biggest trade-off: The cord ties you to your device, and its noise reduction is aimed at clearing up calls rather than giving you a selectable, adjustable level of quiet.
• Who each pick is for: Loop Switch 2 is for people who want to turn down loud rooms, concerts, commutes and open offices without blocking the world entirely. jechan Call Noise Cancelling is for people who want wired headphones that sound rich and keep their voice clear on calls.
Loop Switch 2 is a noise-management tool, not a pair of headphones. The whole idea is adjustability. A manual dial on the earplug lets you move between three levels of reduction: Quiet Mode for your strongest reduction, Engage Mode for holding a conversation without pulling them out, and Experience Mode for live events where you still want to hear the music clearly. The range is 20-26 dB SNR of passive reduction, which means it is your ears doing the work, not a chip.
The fit story is where the second generation earns its keep. Loop slimmed the earplug body, angled the nozzle smaller so it sits more naturally, and ships four ear-tip sizes (XS, S, M, L), with medium pre-installed. That matters because a passive earplug lives or dies by its seal — a loose tip means less reduction and more discomfort. The kit also includes a carry case with moulded silicone inserts, so the plugs stay put in a bag or pocket.
jechan Call Noise Cancelling: Who It's For
jechan Call Noise Cancelling is a wired in-ear headphone with a specific mission: good sound plus clear calls. The dual-driver setup pairs a dynamic driver for deep, punchy bass with a balanced armature driver for balanced mids and crisp highs. That combination is the classic recipe for richer, more detailed audio than a single-driver budget earbud, and it is aimed at music, podcasts and gaming. The 16-ohm impedance is low, so it is easy to drive from a phone or laptop.
The noise story is different from Loop's. jechan uses two layers: active call noise cancellation to cut ambient distractions like traffic, crowds or office chatter on the mic side, and physical isolation from the in-ear seal. That is about making your voice land clearly on the other end of a call — remote work, business calls, commutes. It is not a selectable "quiet mode" you dial up and down.
The design is practical for daily wired use. You get a tangle-resistant cable, an inline controller with push buttons for volume, playback and calls, and a metal enclosure with USB Type-C connectivity. Multiple ear-tip sizes are included for a snug fit during walking or running, and the lightweight build is meant to reduce fatigue over long sessions.
Buy jechan if you want one wired headset that handles music, gaming and calls with a real microphone and inline controls. Skip it if you want total freedom from a cable or if your goal is adjustable, passive quiet rather than audio playback and call clarity.
Side-by-Side: Which Should You Choose?
• Best for listening to music and audio → jechan Call Noise Cancelling. Dual drivers, deep bass and a wired Hi-Fi signal make it a playback device first.
• Best for phone calls and remote work → jechan Call Noise Cancelling. Active call noise cancellation plus a built-in mic and inline controls are built for exactly this.
• Best for concerts, festivals and loud social settings → Loop Switch 2. Experience Mode is designed to keep live sound crisp while Engage Mode lets you talk without removing them.
• Best for focus and commuting quiet → Loop Switch 2. Quiet Mode delivers its strongest passive reduction, with no battery to manage.
• Best for travel and all-day wear comfort → both. Loop offers four tip sizes and a slimmer body; jechan offers soft tips, a lightweight build and multiple sizes.
• Best for people who hate charging → Loop Switch 2. It is fully passive with no electronics or battery at all.
• Best for staying connected to your device → jechan Call Noise Cancelling. The USB Type-C wired connection keeps latency very low (0.1 ms listed) for gaming and video.
If I had to pick one, I would buy Loop Switch 2 — but only because my priority is controlling noise rather than consuming audio. In my opinion, the three-mode dial and the wide 20-26 dB range make it the more flexible tool for the everyday problem of "this room is too loud." That said, if you want headphones that play music and take calls, jechan Call Noise Cancelling is the right buy and Loop cannot replace it. Decide which job you actually have first, then the choice is obvious. Check the current price on Amazon before you commit, since both sit in very different product categories.
FAQ
It depends on whether you want to listen or to block sound. For adjustable passive quiet, I would point to Loop Switch 2 with its three modes and 20-26 dB SNR reduction. For wired audio and call clarity, jechan Call Noise Cancelling with dual drivers and active call noise cancellation is the stronger pick.
No. Loop Switch 2 is a passive hearing-protection earplug with no battery, no electronics and no microphone. It reduces noise across three selectable modes but cannot play audio or handle calls. If you need that, jechan Call Noise Cancelling has a built-in mic and inline call controls.
Not the way Loop does. jechan relies on active call noise cancellation plus physical isolation from the ear-tip seal, which is aimed at clearer calls rather than a user-selectable reduction level. Loop Switch 2 is the one with a manual dial for switching between Quiet, Engage and Experience modes.
