• YINYOO KBEAR KS1 — biggest strength: A 10mm polymer PET dynamic driver tuned V-shape with forward vocals, plus a detachable cable, so the sound stays genuinely HiFi and the cable is replaceable.
• YINYOO KBEAR KS1 — biggest trade-off: It is wired only, has no microphone in this version, and relies on passive sound isolation rather than electronic noise cancellation.
• Supersonic IQ Sound IQ-341 — biggest strength: A fully wireless package with ANC, ENC, dual mics, in-ear detection and a 300mAh touchscreen charging case that adds up to 15 hours of extra playtime.
• Supersonic IQ Sound IQ-341 — biggest trade-off: Battery life per charge is 5 hours, and the sound quality is aimed at everyday listening and calls rather than critical HiFi monitoring.
• Who the KS1 is for: Singers, bass lovers and anyone who wants wired HiFi sound for the money and does not mind a cable.
• Who the IQ-341 is for: Commuters, callers and wireless-first users who want noise cancellation and a smart charging case in one package.
The KBEAR KS1 is a wired in-ear monitor from a brand built around HiFi audio, and the Clear version is the one to notice here. Its translucent rear cavity is a deliberate design choice — the see-through shell gives it a technical, exploratory look that the plain white and black versions do not have. If you like gear that shows its internals, this is the KS1 to pick.
Inside sits a 10mm polymer PET diaphragm driven by a dual magnetic circuit, dual cavity single dynamic driver. The tuning is V-shaped: strong bass, clear imaging and notably good female vocals. The 18-ohm impedance and 20 Hz–20 kHz frequency range mean it is easy to drive from a phone or a laptop without a dedicated amp. The 3.5mm jack keeps it compatible with almost anything wired, and the detachable cable is a real long-term advantage — if the cable fails, you replace the cable, not the earphones.
Comfort is a stated priority. The cavity is made of imported high-density PC material, which the design notes say suppresses diffuse reflection of sound waves inside the shell, and the surface is smooth and skin-friendly. The rounded, contoured shape is meant to lock in so the earphones stay put while running. This version has no microphone, so skip it if you need to take calls. Also worth respecting the manufacturer's own guidance: rest your ears after about two hours, and lower the volume before plugging in to protect the diaphragm. In my opinion, the KS1 is the pick for singers, bass-forward listeners and wired purists who want a genuine HiFi feel without fuss.
The Supersonic IQ-341 is a true wireless earbud built for convenience first. Bluetooth 5.3 handles the connection with a 10-meter range and auto-sync after the first pairing, so it reconnects without you thinking about it. There is no jack at all — this is wireless only — and the black plastic in-ear design is straightforward and pocketable.
The headline feature is the charging case with a touchscreen display. It shows battery status at a glance, and its 300mAh capacity delivers up to 15 hours of extra playtime on top of the earbuds themselves. Each earbud charge lasts about 5 hours, so the case is what gets you through a full day of commuting, calls and errands. Charging is over USB-C, which keeps your cable bag simple.
Audio-wise you get a dynamic driver covering the same 20 Hz–20,000 Hz range, plus active noise cancellation to cut down ambient rumble. The dual microphones pair ANC with ENC (environmental noise cancellation) for clearer calls, and you can summon Google Assistant or Siri with a touch. Touch controls handle volume, playback and the voice assistant. In-ear detection pauses playback when you pull an earbud out and resumes when it goes back in — a genuinely useful touch for anyone who is constantly interrupted.
Who should buy it? Commuters, remote workers on calls, and anyone who refuses to deal with a cable. Who should skip it? If you want critical listening, a replaceable cable or wired reliability with zero charging, this is not the tool. In my opinion, the IQ-341 is the better everyday companion, not the better audiophile device.
• Best for wired HiFi sound → YINYOO KBEAR KS1. A 10mm dynamic driver with V-shape tuning and forward vocals delivers more musical intent than a general-purpose wireless bud.
• Best for noise cancellation → Supersonic IQ Sound IQ-341. It has active noise cancellation; the KS1 relies on passive sound isolation only.
• Best for calls → Supersonic IQ Sound IQ-341. Dual mics with ANC and ENC are purpose-built for voice; the KS1 version here has no microphone.
• Best for battery independence → YINYOO KBEAR KS1. It is wired and never needs charging, while the IQ-341 runs about 5 hours per charge plus up to 15 hours from the case.
• Best for replaceable parts → YINYOO KBEAR KS1. The detachable cable means a worn cable is a cheap fix rather than a dead pair of earphones.
• Best for hands-free convenience → Supersonic IQ Sound IQ-341. Touch controls, voice assistant support and in-ear auto-pause make it the smoother daily driver.
• Best for workouts without fall-out → YINYOO KBEAR KS1. The ergonomic locked-in fit is explicitly designed to stay put while running; the IQ-341 is the better pick for lighter, indoor use.
• Best for travel and commuting → Supersonic IQ Sound IQ-341. Bluetooth 5.3, a 10m range and a touchscreen case that shows battery status solve the two biggest travel annoyances.
If I had to pick one, I would buy the Supersonic IQ Sound IQ-341 for most people. ANC, dual mics, in-ear detection and a charging case with a touchscreen display cover more real-life situations — commuting, calls, workouts and travel — in one device. That said, I would personally choose the YINYOO KBEAR KS1 if sound quality and a wired, charge-free setup matter more than wireless freedom. The KS1 is the better listen; the IQ-341 is the better all-rounder. Buy the one that matches your day, not the spec sheet.

The IQ-341, clearly. It uses active noise cancellation plus ENC for calls. The KS1 offers sound isolation through its in-ear fit only — no electronics involved.
In my opinion, the KBEAR KS1. Its V-shaped 10mm dynamic driver tuning with clear imaging and forward vocals is aimed at musical listening, while the IQ-341 prioritizes convenience and call clarity.
