Krysenix PG3 Gaming Headset UK Review (2026). Tested & Rated

Here’s what eight years of testing headsets has taught me: the gap between budget and premium is shrinking, but most cheap wireless gaming headsets still cut corners where it matters. You’ll find decent drivers paired with awful mics, or solid audio with batteries that die mid-match. The Krysenix PG3 promises 48-hour battery life and dual connectivity modes at the budget end of the market. That’s ambitious. Too ambitious? I spent several weeks finding out whether this headset actually delivers on those claims, or if it’s just another forgettable Amazon listing.

What matters more than the spec sheet is how these drivers are tuned. Budget headsets often throw massive drivers in and call it a day, but driver size alone doesn’t determine audio quality. The tuning, the housing design, and the signal processing all play bigger roles.

Slightly recessed

Present but not harsh

This is a typical gaming headset tuning that emphasises explosions and gunfire over vocal clarity. Works well for action games but less ideal for competitive shooters.

The PG3 has a V-shaped signature that favours bass and treble over midrange. This works well for casual gaming in titles like Elden Ring or Cyberpunk 2077 where environmental immersion matters more than precise positioning. For competitive shooters? You’ll struggle to separate footsteps from background noise.

I tested the PG3 across Valorant, Warzone, and God of War Ragnarök. In single-player games, the boosted bass actually enhances the experience. Kratos’s axe throws have proper weight, and environmental audio feels immersive enough for the price point.

But in Valorant? That’s where the limitations show up. Footsteps get masked by the bass response, and the narrow soundstage makes it harder to judge distance. I could tell direction (left vs right), but front-to-back positioning was vague at best. In one match on Haven, I got caught by a flank I should’ve heard coming because the footsteps blended into the background audio.

Tested in Valorant, Warzone 3, and Apex Legends. The virtual 7.1 surround adds artificial reverb that makes positioning worse, not better. Stick to stereo mode for competitive gaming.

About that virtual 7.1 surround: it’s software processing that widens the stereo image artificially. In practice, it makes everything sound like you’re in a bathroom. Footsteps get washed out with reverb, and directional cues become less precise. I turned it off after the first hour and never looked back.

The wireless connection itself performs well. Krysenix claims sub-20ms latency over 2.4GHz, and I didn’t notice any audio lag during gameplay. No dropouts during my testing period either, though my PC is only about two metres from where I sit.

The mic is where most budget headsets fall apart, and the PG3 is… fine. Not terrible, not great. Just fine.

I recorded several Discord calls and asked for feedback. The consensus was that I sounded clear enough but slightly thin, like most gaming headset mics. The ENC (environmental noise cancellation) does help. My mechanical keyboard is usually quite loud on voice chat, but the PG3 filtered out most of the clacking.

What’s frustrating is the flip-up mute mechanism. There’s no audible click or LED indicator to confirm you’re muted. You just flip it up and hope. I accidentally left myself unmuted twice during testing because there’s no tactile feedback. A proper mute button would’ve been better.

The mic arm is flexible and adjustable up to 120 degrees, which is good. You can position it close to your mouth for better pickup, and it stays where you put it. When you don’t need it, the whole thing detaches easily.

I wear glasses, and the PG3 doesn’t cause pressure points on the frames. The clamping force is balanced – tight enough that the headset stays put when you move your head, but not so tight that it causes headaches.

The ear cups are deep enough that my ears don’t touch the drivers, which is important for comfort. But the protein leather material doesn’t breathe particularly well. After three hours of gaming, my ears were noticeably warm. Not unbearable, but enough that I wanted to take the headset off for a few minutes.

At 285g, the PG3 is lighter than many wireless gaming headsets. The weight distribution is good too – the battery sits in one ear cup but doesn’t make the headset feel lopsided.

The build quality surprised me. Budget headsets often feel like they’ll snap if you look at them wrong, but the PG3 feels reasonably robust. There’s metal reinforcement in the headband where it matters most, and the plastic doesn’t creak when you adjust it.

The RGB lighting is present but subtle – just a ring around each ear cup. You can turn it off to extend battery life, which is the sensible option since you can’t see it while wearing the headset anyway.

This is where the PG3 genuinely impresses. That 48-hour battery claim? It’s real.

I charged the headset fully and used it exclusively for gaming and Discord calls. With the RGB lighting turned off, I got 46 hours before the low battery warning kicked in. That’s nearly a week of gaming for most people without touching a charging cable.

Even with RGB enabled, I managed 34 hours, which is still exceptional for this price bracket. The Ozeino wireless headset claims similar numbers but costs more.

The dual connectivity is genuinely useful too. You can use the 2.4GHz USB dongle for low-latency gaming on PC or PlayStation, then switch to Bluetooth for your phone without unplugging anything. I used this to listen to Spotify between matches without needing a second headset.

One limitation: you can’t use both modes simultaneously. It’s either 2.4GHz or Bluetooth, not both at once. So you can’t have game audio through the dongle and Discord through Bluetooth on your phone, for example.

The lack of Xbox compatibility is frustrating but expected at this price point. Microsoft’s proprietary wireless protocol requires licensing fees that budget manufacturers skip.

Compared to the Ozeino, the PG3 offers dual connectivity modes and 18 extra hours of battery life. The audio quality is similar between both – decent but not exceptional. If you need Bluetooth for mobile gaming or music, the PG3 is the better choice.

Against wired options like the Recon 70, you’re trading audio quality for wireless convenience. The Recon 70 sounds slightly clearer in competitive games because there’s no wireless compression, but you’re stuck with a cable.

If you can stretch your budget to mid-range territory, the Corsair HS55 Wireless offers noticeably better audio quality and more precise positional audio. But it costs nearly twice as much.

The value proposition here is straightforward: you’re paying for wireless convenience and exceptional battery life, not premium audio quality.

If audio quality is your absolute priority, wired headsets in this price range will sound better. The HyperX Cloud II offers superior positional audio for competitive gaming but costs more and tethers you to your desk.

What the PG3 does well is eliminate battery anxiety. You can game for nearly a week without charging, which is genuinely liberating if you’ve used wireless headsets that die mid-session.

The audio quality is adequate for story-driven games, RPGs, and casual multiplayer. You’ll enjoy Elden Ring and Cyberpunk 2077 just fine. But if you’re grinding Valorant ranked or playing competitive Warzone, the muddied footsteps and vague positional audio will frustrate you.
