• KASOTT SoundMaster Pro V1 — biggest strength: A gaming-first design with 10mm dynamic drivers, 16-ohm impedance, a 45° angled in-ear fit, in-line mic with mute and volume control, and a 3.5mm jack that plugs straight into Xbox, PS5, PS4, Switch and PC.
• KASOTT SoundMaster Pro V1 — biggest trade-off: It is a wired 3.5mm headset built around gaming and voice chat, so it is not the pick for someone who mainly wants a USB-C earbud for a phone with no headphone jack.
• jechan Earbud — biggest strength: Two connection types in one package (USB-C and 3.5mm), a hybrid dual-driver setup, an ENC noise-canceling mic for calls, and replaceable S/M/L tips for long listening sessions.
• jechan Earbud — biggest trade-off: Its focus is calls and everyday music rather than positional game audio, and its 32-ohm impedance means it wants a bit more power to reach its full output than a low-impedance set.
• Who each pick is for: KASOTT for console and PC gamers who want chat controls on the cable; jechan for commuters, callers and phone-first listeners who need both plug types.
The SoundMaster Pro V1 is, first and foremost, a gaming earphone. KASOTT builds it around 10mm moving-coil drivers with a 20 Hz–20,000 Hz range and a low 16-ohm impedance, which is the kind of spec sheet that tells you it is meant to be driven easily straight from a controller, a handheld or a laptop headphone jack. The pitch here is positional audio: explosions, gunshots and footsteps rendered with enough separation that you can tell roughly where they are coming from. In-ear noise isolation backs that up by cutting down room noise so the quiet cues stay audible.
Who should buy it: anyone gaming on a 3.5mm source — Xbox Series, PS5, PS4, Switch or a PC with a headphone jack — who wants voice chat controls within reach and a fit that survives a long session. Who should skip it: if your main device is a phone or tablet with only a USB-C port and no adapter, or if you want one earbud for both your laptop and your phone without carrying anything extra, this is not the simpler choice. It is wired, it is 3.5mm, and that is the whole point.
jechan Earbud: Who It's For
The jechan Earbud plays a different game. Its headline feature is connectivity: it ships with both a USB-C plug and a standard 3.5mm plug, so the same set covers a USB-C phone, a tablet, a laptop and any older device with a headphone jack. jechan even notes a small practical detail — press firmly until you hear a slight click — which is the kind of thing that matters when a loose USB-C connection ruins a call. Internally it uses a hybrid dual-driver arrangement with a 10mm driver, 32-ohm impedance and a 20 Hz–20,000 Hz range, tuned for deep bass and clear vocals rather than competitive positional accuracy.
The call side is the other half of the story. The built-in microphone uses environmental noise cancellation to pull your voice out of background chatter — useful on a train, in an open office or on a busy street. The inline control handles volume and calls, and the metal housing with a brown finish gives it a more finished look than the typical plastic bud. jechan also includes replaceable soft tips in S/M/L, so you can swap sizes as your ears fatigue or as the originals wear out, which is a genuinely nice touch for all-day listening.
Who should buy it: commuters, remote workers and anyone who takes a lot of calls and wants one earbud that plugs into almost anything. Who should skip it: if your priority is hearing enemy footsteps in a shooter and you want a mute switch on the cable, the KASOTT's gaming tuning and inline mute are the better fit. The jechan is a generalist; the KASOTT is a specialist.
• Best for console gaming (Xbox, PS5, PS4, Switch) → KASOTT SoundMaster Pro V1. Native 3.5mm jack and gaming-tuned 10mm drivers.
• Best for mixed devices (USB-C and 3.5mm) → jechan Earbud. Two plug types in the box means fewer adapters to carry.
• Best for voice-chat control → KASOTT SoundMaster Pro V1. The inline mic includes a mute switch and volume control on the cable.
• Best for phone calls in noisy places → jechan Earbud. Environmental noise cancellation is built specifically for call clarity.
• Best for easy driving from a controller or handheld → KASOTT SoundMaster Pro V1. At 16 ohm it needs very little power to get loud.
• Best for long listening sessions with tip swaps → jechan Earbud. Replaceable S/M/L soft tips let you refresh the fit over time.
• Best for positional game audio → KASOTT SoundMaster Pro V1. The angled in-ear fit plus isolation is aimed at locating sound cues.
• Best for a single everyday carry earbud → jechan Earbud. It covers commuting, calls and music across more port types.
In my opinion, the KASOTT SoundMaster Pro V1 is the one I would buy if gaming is the reason you are shopping — the 3.5mm jack, inline mute, 16-ohm low-impedance tuning and angled fit all line up with that job, and nothing in the jechan sheet replaces them. I would pick the jechan Earbud instead if your life is split across a USB-C phone and a 3.5mm laptop and you want one set plus a call-focused mic. Buy for the job you actually do most, not the spec sheet that looks longest. If price is the deciding factor, check the current price on Amazon before you commit.
For gaming specifically, yes, in my view. The KASOTT uses a 3.5mm gaming-focused design with a mute switch and gaming-tuned drivers, while the jechan is built around calls and general music listening.
Yes. jechan lists both a USB-C plug and a standard 3.5mm plug, so it covers USB-C audio devices and older 3.5mm jacks. Press until you feel a slight click for a secure connection.
The jechan Earbud. Its environmental noise cancellation is designed to reduce background interference during calls, which the KASOTT's sound-isolation approach does not target in the same way.
The KASOTT SoundMaster Pro V1. Its 3.5mm jack plugs directly into Xbox, PS5, PS4, Switch and PC, and the inline mute and volume controls are built for in-game chat.
