• UNVO S08 biggest strength: a 10mm dynamic driver in a translucent purple shell with an over-ear hook design, plus both 3.5mm and Type-C connectivity — unusually flexible for a wired in-ear.
• UNVO S08 biggest trade-off: passive noise cancellation only, and the single push-button remote is basic compared to a full inline control set.
• KASOTT SoundMaster Pro V1 biggest strength: purpose-built for gaming, with 10mm dynamic speakers, an inline mic with mute and volume control, and three eartip sizes in an aluminum body.
• KASOTT SoundMaster Pro V1 biggest trade-off: it terminates in a 3.5mm aux jack only, so USB-C-only phones and laptops are left out unless you have an adapter.
• Pick UNVO S08 if you split your time between music, calls and gaming across different devices and want one wired earphone to cover all of it.
• Pick KASOTT SoundMaster Pro V1 if you play on Xbox, PlayStation, Switch or PC and want controls at your fingertips mid-match.
The UNVO S08 is a wired in-ear monitor built around a 10mm dynamic driver, with an impedance of 16 ohm, a frequency response starting at 20 Hz and a sensitivity of 108 dB. In plain terms, that combination points to an easy-to-drive earphone — low impedance and high sensitivity usually mean you don't need a dedicated amplifier to get usable volume out of a phone, tablet or laptop headphone jack. The model name, S08HIFI, and the "HiFi Stereo Sound Stage" framing tell you where UNVO is aiming: a wide, spacious presentation rather than a bass-first tuning. I can't verify the sound signature from a spec sheet, but the driver size and spec profile are consistent with a general-purpose listening earphone rather than a single-purpose gaming set.
The design is the part that stands out. The housing is a translucent purple plastic shell that shows the internal components, which is a deliberate aesthetic choice — you either love that look or you don't. The fit is an over-ear hook style, meaning the cable routes up and over the back of your ear before dropping down. That's the same approach used on stage monitors, and the practical benefit is stability: the earphone resists tugging when you turn your head or move around, which matters if you wear them for long stretches or while moving.
Connectivity is where the S08 earns its keep. It ships with both a 3.5mm jack and Type-C compatibility, so it can plug into a phone with a headphone jack, a laptop, a tablet, a handheld console with a 3.5mm port, or a USB-C device. There's an inline microphone and a single push-button remote for calls and playback. Noise control is passive — the seal of the eartip does the work, not electronics. Weighing in at 30 g with a one-year warranty and an adult age rating, this is a straightforward everyday earphone.
Who should skip it: if you need inline volume and mute controls, or you want a metal housing, or you're plugging exclusively into a USB-C-only device and don't want to think about adapters, the S08's single-button remote and plastic shell won't be the fit.
KASOTT SoundMaster Pro V1: Who It's For
The KASOTT SoundMaster Pro V1 is unapologetically a gaming earphone. The spec sheet leads with 10mm dynamic speakers tuned to reproduce what KASOTT describes as powerful bass, and the language is all about in-game audio cues: explosions, character voices, gunshots and enemy footsteps presented with a sense of direction. That's the classic pitch for positional audio in competitive play, and a 10mm dynamic driver is a reasonable foundation for it. KASOTT also states the earphones work for music and calls, so it isn't locked to gaming only.
The physical design is where it separates from the UNVO. The housing is aluminum rather than plastic, which generally reads as a more premium feel in hand and a bit more resistance to everyday wear. The earbuds use a 45° inclined ergonomic shape, and KASOTT includes three pairs of eartips in small, medium and large. That's a real practical advantage: tip fit is the single biggest factor in both comfort and how much outside noise the seal blocks, and having three sizes in the box means you can actually find yours. The flexible material is described as reducing ear pain over long sessions — useful when you're three hours into a ranked run.
Controls are the other headline. The inline mic includes a mute and volume control, which is exactly what a console or PC player wants: mute yourself without reaching for a menu, and adjust volume without alt-tabbing. Connectivity is 3.5mm aux only, and the compatibility list is explicit — Xbox Series, Xbox One, PS5, PS4, Switch and PC with a 3.5mm jack. Noise control is sound isolation via the tip seal. It carries a two-year warranty, double the UNVO's one year.
Who should buy it: console and PC gamers who want in-game audio cues, inline mute and volume at their fingertips, and a metal-bodied earphone with three tip sizes to dial in fit.
Who should skip it: if you listen mainly on a USB-C phone or laptop with no 3.5mm port, the fixed 3.5mm aux jack is a real limitation, and if you prefer an over-ear cable routing for stability, this is a straight-down in-ear design.
• Best for connection flexibility → UNVO S08. It's the only one of the two with both 3.5mm and Type-C, so it covers more of your devices out of the box.
• Best for console and PC gaming → KASOTT SoundMaster Pro V1. The compatibility list names Xbox, PlayStation, Switch and PC directly, and the inline mute/volume controls suit live play.
• Best for inline controls → KASOTT SoundMaster Pro V1. Mute plus volume beats a single push button.
• Best for fit stability while moving → UNVO S08. The over-ear hook design holds the cable in place; the KASOTT is a conventional in-ear.
• Best for fit customization → KASOTT SoundMaster Pro V1. Three eartip sizes (S/M/L) versus a single supplied fit.
• Best housing durability feel → KASOTT SoundMaster Pro V1. Aluminum versus the UNVO's plastic shell.
• Best for long-session comfort claims → KASOTT SoundMaster Pro V1. The 45° inclined, flexible-material design is explicitly aimed at reducing prolonged-wear discomfort.
• Best warranty coverage → KASOTT SoundMaster Pro V1. Two years against the UNVO's one.
• Best for a distinctive look → UNVO S08. The translucent purple shell is a genuine design statement; the KASOTT is black and understated.
If I had to pick one, I'd buy the KASOTT SoundMaster Pro V1. In my opinion it does more of the specific things a wired in-ear buyer actually wrestles with: it gives you inline mute and volume, three eartip sizes so you can get a real seal, an aluminum body that should shrug off daily handling, and a two-year warranty. The gaming focus is narrow, but the controls and tip options are useful well beyond gaming.
I'd only steer you to the UNVO S08 if connection flexibility is your priority — that 3.5mm plus Type-C combination is the one thing the KASOTT simply cannot match, and the over-ear hook fit is better for wearing while active.
what is in ear earphones
In-ear earphones are small earphones whose tips sit inside the ear canal rather than resting against the outer ear. Both the UNVO S08 and KASOTT SoundMaster Pro V1 are in-ear models, which is why both rely on the eartip seal for passive noise isolation rather than active electronics.
what is in ear monitor earphones
An in-ear monitor, or IEM, is an in-ear earphone originally designed for performers to hear a mix on stage, typically worn with the cable routed over the ear. The UNVO S08 fits that description — its over-ear hook design and 10mm dynamic driver are consistent with an IEM-style build.
how to clean earphones ear wax
Wipe the eartips and nozzle gently with a dry cloth or a soft brush, and remove the tips periodically to clear wax from the sound tube. On the KASOTT SoundMaster Pro V1 you can pull the eartips off to clean them properly, and its three sizes mean you can swap in a fresh set while one is being cleaned.
how to ear earphones
Seat the tip so it seals the ear canal without pressure — a good seal is what gives you bass and blocks outside noise. The KASOTT SoundMaster Pro V1 includes small, medium and large tips plus a 45° inclined shape to help you find that seal; the UNVO S08 relies on its over-ear hook to hold position once seated.
