How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a low-latency wireless gaming headset with a boom mic, 2.4GHz and Bluetooth, and up to 50 hours of battery, choose Krysenix 2.4; if you need simple wired over-ear headphones with memory foam earcups, a 3.5mm plug and no charging at all, choose Sunicon Over Ear Headphones.
• Krysenix 2.4 — biggest strength: true wireless gaming flexibility: a 2.4GHz dongle for PC, PS4, PS5, Mac, laptop and Switch, Bluetooth 5.4 for phones and tablets, plus ≤20ms latency and a battery rated at up to 50 hours with RGB off.
• Krysenix 2.4 — biggest trade-off: it is the more complex product. It ships as a 2-in-1 transmitter setup, needs 2.5–3 hours to charge, and works with neither mode on Xbox.
• Sunicon Over Ear Headphones — biggest strength: zero fuss. A universal 3.5mm jack, memory foam pads, a nine-notch adjustable headband and folding earcups with 90/180° swivel — nothing to charge, nothing to pair.
• Sunicon Over Ear Headphones — biggest trade-off: it is wired only, has no microphone and no wireless mode, so it cannot be used cable-free with a phone or console controller at a distance.
• Who each pick is for: Krysenix 2.4 is for gamers who want wireless freedom and voice chat; Sunicon is for listeners who want a comfortable, portable wired pair for music, study, travel and studio-style listening.
The Krysenix 2.4 is built around one idea: cutting the cable without cutting the speed. Its 2.4GHz dongle mode is the part that matters most for gaming, because it delivers lossless wireless audio at ≤20ms latency — low enough that what you see and what you hear stay locked together. If you have ever played a shooter over ordinary Bluetooth and felt that half-second disconnect between a sound and its source, this is the feature that fixes it. The 50mm titanium-coated drivers and 20Hz–20KHz range are aimed at the same job: separating gunfire from footsteps so you can place a direction rather than just hear noise.
Around that core, Krysenix adds the things a headset needs for long sessions. The battery is rated at 30–35 hours with RGB lighting on and up to 50 hours with it off, and a full charge takes roughly 2.5 to 3 hours. The microphone is adjustable up to 120° with noise-cancelling technology, so you can park it near your mouth for chat and swing it out of the way when you are done. The adjustable headband and imitation protein leather earcups are designed to reduce pressure, including for glasses wearers. The whole thing folds, and there is a Type-C charging cable, a wireless transmitter and a manual in the box, backed by a one-year warranty.
Buy it if you play on PC, PS4, PS5, Mac, laptop or Switch and you want one headset that swings between dongle mode for gaming and Bluetooth 5.4 for your phone. Skip it if you are on Xbox — neither mode supports it — or if you dislike managing a battery and a transmitter. Also note the setup detail that trips people up: you combine the 2-in-1 transmitter before connecting to PS5, PS4, PC or laptop. Read the manual once and you are fine. You can check the current price on Amazon if you want to see where it lands for you.
The Sunicon Over Ear Headphones go the opposite direction, and do it deliberately. There is no battery, no dongle, no pairing and no charging. You plug the 3.5mm jack into a phone, laptop, desktop, audio interface, mixer, gaming console or MP3 player and it works. That universality is the entire appeal: one cable, every device with a headphone socket, no compatibility list to memorise and no mode to switch.
The comfort story is where Sunicon puts its effort. The memory foam ear pads are designed to conform to your ears over time and create a tight seal, which gives you passive noise isolation — the kind that blocks out an office, a commute or a noisy room without any electronics involved. The nine-notch adjustable headband is meant to fit a wide range of head shapes and sizes with just enough tension to stay put, whether you are moving around a studio or sitting still for a long session. The earcups swivel 90/180° and fold down, so the whole thing packs small.
On sound, Sunicon quotes a 20Hz–20KHz frequency response — the full range of human hearing — and 110dB sensitivity, which tells you it does not need much power to get loud. Deep bass is part of the design brief. The frame is ABS in black, and the package is just the headset itself, with a 90-day manufacturer warranty.
Side-by-Side: Which Should You Choose?
• Best for gaming audio with low latency → Krysenix 2.4. The ≤20ms 2.4GHz mode is the whole point.
• Best for voice chat → Krysenix 2.4. Sunicon has no microphone at all; Krysenix has an adjustable, noise-cancelling boom mic.
• Best for battery life → Krysenix 2.4. Up to 50 hours with RGB off, 30–35 hours with it on, from a 1200mAh battery.
• Best for wireless convenience across devices → Krysenix 2.4. 2.4GHz dongle plus Bluetooth 5.4 covers PC, PS4, PS5, Mac, laptop, Switch, phones and tablets.
• Best for plug-and-play simplicity → Sunicon Over Ear Headphones. A 3.5mm jack works with virtually anything, with no charging or pairing.
• Best for all-day comfort on a budget-minded wired setup → Sunicon Over Ear Headphones. Memory foam pads, a nine-notch headband and passive noise isolation.
• Best for travel and packing → tie, with a lean to Sunicon. Both fold, but Sunicon adds 90/180° swivel earcups and a lightweight build.
• Best for Xbox owners → Sunicon Over Ear Headphones. Krysenix works with neither its 2.4GHz nor Bluetooth mode on Xbox.
In my opinion, most people reading this comparison should buy the Krysenix 2.4. The reason is not that it is fancier — it is that it does more of the jobs a headset actually gets asked to do. Wireless gaming on PC or PlayStation, voice chat with a real boom mic, Bluetooth for your phone, and a battery that lasts long enough that you stop thinking about it. The Sunicon is the better pick only if your priority is a simple, comfortable, wired pair for music and listening. If you game with a mic, I would take the Krysenix 2.4. Check the current price on Amazon for both before you decide — the numbers move, the trade-offs above do not.
FAQ
No. They are wired over-ear headphones with a 3.5mm jack, so there is no battery to charge and no pairing step. That is a genuine advantage if you dislike managing cables and charge cycles — the trade-off is that you cannot move away from your device.
No. The manufacturer states that neither the 2.4GHz dongle mode nor Bluetooth mode is compatible with Xbox. It supports PC, PS4, PS5, Mac, laptop, phone, tablet and Switch, and you combine the 2-in-1 transmitter before connecting to PS5, PS4, PC or laptop.
Both are designed for extended wear, in different ways. Krysenix uses an adjustable headband with soft imitation protein leather earcups and a foldable frame; Sunicon uses memory foam pads that conform over time plus a nine-notch headband. If you wear glasses, Krysenix explicitly designs its earcups to reduce pressure — that is the detail I would weigh most.
