How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a proven Logitech wireless gaming headset with big 50 mm drivers and a huge install base of PC players behind it, choose Logitech G935; if you need a modern wireless headset with Bluetooth 5.4, multi-device compatibility and dramatically longer battery life, choose Krysenix 2.4. Both are over-ear wireless gaming headsets with 50 mm dynamic drivers. They are not the same product at all once you look at how they connect, how long they run, and how they were built.
• Logitech G935 — biggest strength: Logitech's 2.4 GHz RF wireless with a 15 m range gives you a rock-solid, low-fuss PC connection, and the 50 mm dynamic drivers cover a full 20 Hz–20 kHz range. Biggest trade-off: this is a renewed unit with a 90-day limited warranty, and battery life is modest — 8 hours with default lighting and 12 hours without.
• Krysenix 2.4 — biggest strength: a 1200 mAh battery rated for 30–35 hours with RGB on and up to 50 hours with it off, plus dual 2.4 GHz dongle and Bluetooth 5.4 modes. Biggest trade-off: it skips Xbox entirely, and the PS5/PS4/PC setup requires combining the 2-in-1 transmitter first.
• Pick Logitech G935 if you're a PC-first player who wants a simple RF dongle connection and a refurbished unit is fine by you.
• Pick Krysenix 2.4 if you want one headset for PC, PS5, PS4, Switch, phone, laptop and tablet, and you hate charging mid-session.
The G935 is a PC gaming headset through and through. Its wireless tech is RF at 2.4 GHz with a stated range of 15 metres, which tells you Logitech built this around a dedicated dongle rather than Bluetooth pairing. That's a design decision with real consequences: you get one clean, dedicated link to your machine instead of juggling pairing menus. The 50 mm dynamic drivers and 20 Hz–20 kHz frequency range are the standard recipe for full-range gaming audio — deep enough for explosions, high enough for footsteps and voice chat.
The physical design leans gamer: over-ear cups in faux leather and plastic, a blue colourway, and media controls built into the headset. Noise control is listed as sound isolation, so this is a passive seal rather than active noise cancelling — fine for a quiet room, less useful if you game next to a noisy fan or an open window. Charging takes up to 12 hours, and battery life runs 8 hours with default lighting or 12 hours with lighting off. In practice that means you're charging it most days if you play long sessions, and you'll want to think about your charging routine before you commit.
The honest caveat is the listing itself: this is a Renewed product. That means the unit has been inspected and tested to work and look like new, and it carries a 90-day limited warranty rather than a full manufacturer term. If you're comfortable with refurbished gear and you want a Logitech-branded PC headset with a straightforward RF dongle, this fits you. If you want a brand-new unit with a one-year warranty, or you need to connect to a PS5, Switch or phone, this is not your headset.
The Krysenix 2.4 is the opposite philosophy: one headset for everything. It ships with a 2.4 GHz dongle for PC, PS4, PS5, Mac, laptop, phone and Switch, and you can flip to Bluetooth 5.4 for phones, tablets and Switch on the fly. That dual-mode design is the headline feature — you can be on a PC game over the dongle and take a call on your phone over Bluetooth without swapping hardware.
Battery is where it runs away from the G935. A 1200 mAh cell charges in 2.5 to 3 hours and is rated for 30–35 hours with RGB lighting on, or up to 50 hours with lighting off. For someone who games several evenings a week, that's roughly a week of play between charges, and it removes the daily-charge chore entirely.
The rest of the package is built for long sessions and travel. The headband adjusts, the earcups use soft imitation protein leather over breathable sponge, and Krysenix specifically calls out comfort for people who wear glasses — a detail most budget headsets ignore. The microphone is flexible, adjusts up to 120°, and uses noise-cancelling tech to cut background noise while keeping your voice clear. The whole thing folds, which matters if you carry it between a desk and a console. RGB lighting on the shell is there if you want the aesthetic, and you can turn it off to double your runtime.
Two limitations are worth repeating plainly: it does not work with Xbox at all, in either mode, and for PS5, PS4, PC or laptop you must combine the 2-in-1 transmitter before connecting. It also uses button controls rather than the touch/media control style — a matter of preference, but worth knowing if you're used to a different layout.
Side-by-Side: Which Should You Choose?
• Best for PC-only simplicity → Logitech G935. A single 2.4 GHz RF dongle, 15 m range, no mode switching.
• Best for multi-device use → Krysenix 2.4. 2.4 GHz dongle plus Bluetooth 5.4 covers PC, PS5, PS4, Switch, Mac, phone, laptop and tablet.
• Best for console and handheld owners → Krysenix 2.4. PS5, PS4 and Switch are supported (just remember to combine the transmitter); Xbox is not supported by either headset.
• Best for warranty confidence → Krysenix 2.4. A 1-year warranty versus 90 days on the renewed G935.
• Best for refurbished-savvy buyers → Logitech G935. If a professionally inspected renewed unit with a Logitech badge appeals to you, it's a legitimate route.
• Best for travel → Krysenix 2.4. The foldable design is the only one of the two built to be packed away.
• Best for wearing glasses long-term → Krysenix 2.4. The breathable sponge-and-leather earcups are specifically designed with glasses wearers in mind.
I'd buy the Krysenix 2.4. The battery gap is the deciding factor for me — 50 hours versus 12 is not a small difference, it changes how you live with the headset. Add Bluetooth 5.4, PS5 and Switch support, folding portability and a 1-year warranty, and it simply covers more of what a modern gamer needs from one pair of headphones. I'd only pick the Logitech G935 if I were strictly a PC player who wants a dedicated RF dongle and is comfortable buying renewed. Check the current price on Amazon before you decide — that's the one variable that can flip this call.
Not on the numbers. The G935 has a 15 m RF range and Logitech's brand behind it, but it's a renewed unit with a 90-day warranty and only 8–12 hours of battery. The Krysenix 2.4 offers Bluetooth 5.4, multi-console support and 30–50 hours of playtime.
It works with PS5 and PS4 over the 2.4 GHz dongle, but you must combine the 2-in-1 transmitter first. It does not work with Xbox in either 2.4 GHz or Bluetooth mode.
Logitech G935: 8 hours with default lighting, 12 hours with lighting off. Krysenix 2.4: 30–35 hours with RGB lighting on, up to 50 hours with it off, from a 1200 mAh battery that charges in 2.5–3 hours.
The Krysenix 2.4 is the safer bet. Its adjustable headband and soft, breathable sponge-and-leather earcups are specifically designed to reduce pressure and accommodate glasses during extended wear.
