How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wireless work headset that connects to a PC or laptop with a plug-and-play dongle and also works over Bluetooth, choose Middle Rabbit SW4; if you need a wired, low-cost gaming earphone with an in-line mic and a 3.5mm plug for consoles and handhelds, choose KASOTT SoundMaster Pro V1.
• Middle Rabbit SW4 — biggest strength: dual connectivity (2.4GHz USB dongle plus Bluetooth 5.1) with four microphones, a companion app, and a charging case rated for up to 30 hours total.
• Middle Rabbit SW4 — biggest trade-off: it is a wireless, battery-dependent system, and the earbuds themselves are rated at only about 5 hours per charge, so long back-to-back days need the case nearby.
• KASOTT SoundMaster Pro V1 — biggest strength: a wired 3.5mm connection that never needs charging, with an in-line mic that has mute and volume control, and a 45° angled fit with three eartip sizes.
• KASOTT SoundMaster Pro V1 — biggest trade-off: it is wired only, so you are tethered to the device, and it relies on the source device for its connection rather than offering its own wireless link.
• Who each pick is for: the Middle Rabbit SW4 is for people who live in video meetings on a computer; the KASOTT SoundMaster Pro V1 is for gamers on Xbox, PlayStation, Switch or PC who want a cheap, no-battery wired option.
The Middle Rabbit SW4 is built around one idea: getting clean audio into a computer without fuss. It ships with a USB-C dongle plus a USB-C to USB-A adapter, so it can plug into a modern laptop or an older desktop with a standard USB port. That 2.4GHz link is the part that matters for work — the spec sheet lists audio latency at 40 milliseconds, which is the kind of number that keeps voices and lips roughly in sync during a call. If you have ever been the person whose Bluetooth headset drifted a half-second behind on a Zoom call, that figure is the whole pitch.
On top of the dongle, it also does straight Bluetooth 5.1, so the same earbuds can pair with a phone or tablet when you are away from the desk. Each earbud carries two microphones — four total — which is a lot of mic hardware for this category and is aimed squarely at making your voice legible in a meeting rather than just audible. The 10mm dynamic drivers cover a 20Hz–20,000Hz range, and there is a Music Mode and a low-latency Game Mode you can flip between in the Middle Rabbit app. The app also handles touch-control settings and battery monitoring, which is genuinely useful when you are trying to keep track of charge during a workday.
Who should buy it: remote workers, students, and anyone who spends hours a day in Zoom, Webex, or Skype and wants one headset that handles both the laptop and the phone. The claimed runtime is 6–8 hours per charge with three extra charges in the case, for up to 30 hours total, though the product information lists average battery life at 5 hours — treat the case as part of the system, not an accessory.
Who should skip it: console gamers, since this is a PC-and-laptop-first product. Also skip it if you want zero charging overhead, or if you dislike in-ear buds with rounded silicone tips. And if you need active noise cancellation, note this is passive isolation only — the seal does the work.
The KASOTT SoundMaster Pro V1 is the opposite philosophy: wire it in and forget about it. It terminates in a 3.5mm jack and lists compatibility with Xbox Series, Xbox One, PS5, PS4, Switch, and PC. There is no battery, no pairing, no dongle, and no charging case to keep track of — you plug it into a controller or a headphone jack and it works. For anyone who has watched a wireless headset die mid-match, that simplicity is the feature.
The audio side is a single 10mm dynamic driver per side, with 20 ohm impedance and 42dB sensitivity — both easy numbers to drive, meaning a controller or handheld can push them without a separate amp. The tuning is described as bass-forward with strong positional cues: footsteps, gunshots, and distant explosions placed in three-dimensional space, which is exactly what you want in a shooter. It is also positioned for music and calls, so it is not a one-trick gaming product.
The fit gets real attention here. The nozzles are set at a 45° angle, and KASOTT includes three eartip sizes — small, medium, and large — in a flexible material meant to reduce the soreness that comes from long sessions. The housing mixes aluminum, plastic, and stainless steel, which is a more substantial build than the price-adjacent plastic norm, and the color is green. Warranty coverage is listed at two years, which is unusually long for this segment.
Who should buy it: console and PC gamers who want a wired, latency-free connection, plus anyone who wants a cheap second pair for a Switch or a controller and does not want to manage another battery. Who should skip it: anyone who needs wireless freedom, anyone on a phone or laptop without a 3.5mm jack, and anyone who wants app-based EQ or touch controls — the only on-board control is the in-line volume and mute.
• Best for work calls and video meetings → Middle Rabbit SW4. Four microphones, a 2.4GHz low-latency dongle, and stated sync with Zoom, Webex, and Skype.
• Best for console gaming → KASOTT SoundMaster Pro V1. Native 3.5mm compatibility with Xbox, PlayStation, and Switch, with an in-line mute.
• Best for people who hate charging → KASOTT SoundMaster Pro V1. Wired means it is always ready; the Middle Rabbit relies on a 5-hour bud charge plus case top-ups.
• Best for switching between PC and phone → Middle Rabbit SW4. The dongle handles the computer, Bluetooth 5.1 handles everything else.
• Best for long-session comfort → KASOTT SoundMaster Pro V1. The 45° angled nozzle and three eartip sizes are aimed directly at extended wear.
• Best for tuning your own sound → Middle Rabbit SW4. The app gives you touch-control settings, battery readouts, and a music/game mode switch.
• Best for mic control at your fingertips → KASOTT SoundMaster Pro V1. Volume and mute sit on the cable, no app required.
• Best for a durable-feeling build → KASOTT SoundMaster Pro V1. Aluminum and stainless steel in the housing, backed by a two-year warranty.
In my opinion, the Middle Rabbit SW4 is the better buy for most people reading this, because the hard problem it solves — getting reliable, low-latency audio and a clear mic into a computer for meetings — is the problem most buyers actually have. The dongle-plus-Bluetooth combination means you are not locked to one device, and the app makes the battery and touch controls manageable rather than mysterious. That said, I would pick the KASOTT SoundMaster Pro V1 without hesitation if my priority were gaming on a console or handheld, or if I simply refused to think about charging again. Two genuinely different tools: pick the one that matches where you will actually use it. Check the current price on Amazon for whichever one fits your setup.
For consoles — Xbox, PlayStation, Switch — the KASOTT SoundMaster Pro V1 is the natural fit because it plugs straight into a 3.5mm jack. The Middle Rabbit SW4 does have a low-latency Game Mode at 40ms, but it is aimed at PC and laptop use rather than console hardware.
No. It is a wired earphone with a 3.5mm jack, so there is no battery at all. The Middle Rabbit SW4 is the opposite: about 5 hours per earbud charge, with three additional charges in the case for up to 30 hours total.
The Middle Rabbit SW4 carries four microphones — two per earbud — which is a lot of hardware aimed at call clarity. The KASOTT SoundMaster Pro V1 uses an in-line mic on the cable with mute and volume controls, which is simpler but gives you a physical mute button.
The KASOTT SoundMaster Pro V1 leans hardest into comfort, with a 45° angled nozzle and three eartip sizes in a flexible material. The Middle Rabbit SW4 uses rounded silicone tips and is light at 45g total, but it is a standard in-ear fit with no angle or size options listed.
