• KASOTT SoundMaster Pro V1 — biggest strength: a complete wired gaming headset in one package, with 10 mm dynamic drivers, a 3.5 mm jack, and an in-line remote that handles mute and volume.
• KASOTT SoundMaster Pro V1 — biggest trade-off: it's a single pair of in-ear buds, so only one person listens, and the passive noise cancellation relies on the seal in your ear rather than active electronics.
• IIISOGNO 3.5mm — biggest strength: two TRRS female ports that both carry full mic and stereo audio, so two headsets share one device at once.
• IIISOGNO 3.5mm — biggest trade-off: it's an adapter, not a listening device. It makes no sound on its own and needs a TRRS headset with a built-in mic to pass mic audio through.
• Who KASOTT is for: the solo player or listener who wants one ready-to-go wired headset for Xbox, PlayStation, Switch, or PC.
• Who IIISOGNO is for: couples, friends, or family who want to split one phone, tablet, laptop, or PC between two headsets.
The SoundMaster Pro V1 is built around a simple idea: one wired headset that covers gaming and everyday listening. It uses 10 mm dynamic drivers with a 20 Hz–20,000 Hz frequency range and 20 ohm impedance, which is a low-impedance, easy-to-drive setup — the kind of load a controller jack or laptop headphone port handles without trouble. The 3.5 mm wired connection keeps latency out of the picture, which matters for games where audio cues need to land on time.
The in-line remote is the practical heart of it. Three quick-action buttons give you volume control and a mute, so you can kill your mic mid-match or nudge levels without Alt-Tabbing into a menu. The housing is aluminum in a Flaming Red finish, and the rounded-tip in-ear design leans on passive noise cancellation — the eartip seal blocks some outside noise, which helps at home, on a commute, or anywhere you want to shut out a noisy room. KASOTT backs it with a 2-year warranty.
Buy it if you're a console or PC player who wants a single wired headset with a mic you can mute on the fly, and you like the idea of in-ear buds you can also use for music and calls. Skip it if two people need to listen together — this is one headset for one person, and if you want to share a source you'll need a splitter like the IIISOGNO instead.
The IIISOGNO 3.5mm is a different kind of product entirely — a 1-foot TRRS splitter that turns one 3.5 mm output into two. Both female ports support full mic and stereo audio, so two people wearing TRRS headsets can share music, movies, calls, or games with complete headset features, not just sound. That's the important distinction: many cheap splitters only pass audio one way, but here both jacks carry mic and audio.
Compatibility is broad — phones, tablets, laptops, and PCs. One caveat worth knowing before you buy: TRS headphones or speakers will work on it for sound only. To use a mic, you need a headset with a TRRS plug and a built-in mic. The build is travel-friendly: a braided nylon cable that resists tangling, an aluminum housing that's lightweight, scratch-resistant, and anti-corrosion, and gold-plated connectors to cut signal loss for clearer audio. It weighs about 20 g and carries a 1-year warranty.
Buy it if you regularly want two people on one screen or one phone — a couple watching a movie on a laptop, two friends on a call, or a parent and kid sharing a tablet. Skip it if you need something that actually produces sound. This is an accessory; you still need headsets to plug into it.
Side-by-Side: Which Should You Choose?
• Best for two people sharing one device → IIISOGNO 3.5mm. Two TRRS ports, mic and audio on both.
• Best for console compatibility → KASOTT SoundMaster Pro V1. Designed for Xbox Series, Xbox One, PS5, PS4, Switch, and PC over 3.5 mm.
• Best for phones, tablets, and laptops → IIISOGNO 3.5mm. Works across most 3.5 mm TRRS devices.
• Best for blocking outside noise → KASOTT SoundMaster Pro V1. Passive noise cancellation from the in-ear seal.
• Best for durability on the move → IIISOGNO 3.5mm. Braided nylon cable plus aluminum housing.
• Best for a complete out-of-the-box setup → KASOTT SoundMaster Pro V1. It's the headset; the IIISOGNO needs headsets you already own.
• Best for travel and shared listening → IIISOGNO 3.5mm. Compact, 1 FT, tangle-resistant.
In my opinion, these two aren't really rivals — they solve different problems, and the right pick comes down to how many people are listening. If you're the one wearing the headset and you want a wired gaming setup with a mic you can mute instantly, I'd buy the KASOTT SoundMaster Pro V1. If your priority is letting a second person hear and talk through the same device, I'd buy the IIISOGNO 3.5mm — just remember it's an adapter, so you'll need your own headsets. For a single buyer who games solo, KASOTT is the more complete purchase.
KASOTT. It's an actual headset with 10 mm drivers, a 3.5 mm jack, and an in-line mic with mute, built for Xbox, PlayStation, Switch, and PC. The IIISOGNO makes no sound on its own.
Yes — both female TRRS ports support mic and audio together, so two people can talk and listen at once. You do need TRRS headsets with built-in mics; TRS headphones will only pass sound.
Yes. It uses a standard 3.5 mm wired jack, so any device with a compatible 3.5 mm port can drive it. The 20 ohm impedance makes it easy to power.
They complement each other. Use the KASOTT for solo gaming and calls, and keep the IIISOGNO around when a second person wants to join on one screen. Check the current price on Amazon before deciding.
