If you want marathon battery life and a low-latency USB-adapter Game Mode tuned for Xbox, choose LucidSound LS100X; if you need a budget-minded 2.4GHz dongle headset that also folds up and lights up, choose Krysenix 2.4. Both chase the same goal — cutting audio lag so explosions and footsteps land on time — but they get there in very different ways, and the right one depends on your platform and how long you play.
• LucidSound LS100X — biggest strength: up to 130 hours over Bluetooth or up to 72 hours in Game Mode through the USB adapter, plus a 50mm driver setup with three EQ modes (Signature, Bass Boost, FPS) and a detachable boom mic with a backup built-in mic.
• LucidSound LS100X — biggest trade-off: it's built around Xbox and the USB-adapter route, and it lists no active noise cancellation (noise control: None), so it won't isolate you the way a noise-cancelling set would.
• Krysenix 2.4 — biggest strength: a 2.4GHz dongle rated at ≤20ms latency with wide compatibility (PC, PS4, PS5, Mac, Switch and more), 50mm titanium-coated drivers, and RGB lighting you can toggle.
• Krysenix 2.4 — biggest trade-off: it's explicitly not compatible with Xbox in either mode, and the microphone isn't compatible in every mode, so Xbox owners are out and chat setup needs care.
• Who the LS100X is for: Xbox Series X|S players and long-session grinders who want low-latency Game Mode plus Bluetooth flexibility.
• Who the Krysenix 2.4 is for: PC, PlayStation, Switch and mobile players who want a low-latency dongle set with a foldable, travel-friendly frame.
The LS100X is built around one idea: low-latency wireless that doesn't quit. Its Game Mode connects through the included Wireless USB Adapter and is described as low-latency and interference-free, with a strong connection even in crowded Wi-Fi environments. That last point matters. If you game in a house where everyone's streaming and the airwaves are busy, a headset that holds its link is worth more than one that sounds slightly better on paper. Pairing is simple with the included adapter, so you're not fighting menus.
Then there's the battery story. You get up to 130 hours when connected over Bluetooth or up to 72 hours in Game Mode on a single charge. Bluetooth 5.2 is on board too, with a listed range of 100 meters, so the same headset that handles your console can flip to music and calls on a phone or tablet. For someone who hates mid-session charging, that's the headline.
Buy it if you're on Xbox Series X|S, you want low-latency Game Mode plus Bluetooth in one headset, and you play for hours at a stretch. Skip it if you need active noise cancellation or you're gaming on a platform outside its intended Xbox-and-Bluetooth mix.
Krysenix 2.4: Who It's For
Krysenix takes the opposite approach: maximum platform reach at a low-latency spec. The 2.4GHz lossless wireless mode is rated at ≤20ms latency, which is the number to focus on — it's designed to kill audio/video desync so gunfire and footsteps line up with what you see. You connect through a 2-in-1 transmitter (you combine it before plugging into PS5, PS4, PC or laptop), and Bluetooth 5.4 covers phones, tablets and Switch for wireless listening on the move.
The drivers are 50mm titanium-coated, tuned for clear highs and deep lows with the positional detail shooters rely on, over a 20Hz–20KHz range at 32 ohms. Controls are physical push buttons rather than touch, which some players prefer because you can feel your way to volume and mic adjustments without looking.
Battery is a 1200mAh cell that charges in 2.5 to 3 hours and runs 30–35 hours with RGB on or up to 50 hours with RGB off. That's a real, practical trade: the RGB lighting is a look, but turning it off roughly extends your session. The mic is adjustable up to 120° with noise-cancelling tech that targets background noise so your voice comes through clearly in chat. Comfort comes from an adjustable headband and soft imitation-protein leather earmuffs over breathable sponge, and the whole set is foldable for travel.
Two limitations are worth repeating plainly. Both wireless modes are not compatible with Xbox, and the microphone isn't compatible in every mode. So if you're an Xbox player, this isn't your headset — full stop. And if crystal-clear chat is your top priority, verify the mic works in the mode you'll actually use.
Side-by-Side: Which Should You Choose?
• Best for battery life → LucidSound LS100X. Up to 130 hours over Bluetooth or up to 72 hours in Game Mode beats the Krysenix's 50 hours (RGB off) or 30–35 hours (RGB on).
• Best for Xbox gaming → LucidSound LS100X. The Krysenix is explicitly not compatible with Xbox in either mode.
• Best for PC, PS5, PS4, Mac and Switch → Krysenix 2.4. Its 2.4GHz dongle and Bluetooth 5.4 cover those platforms; the LS100X is centered on Xbox plus Bluetooth devices.
• Best stated latency figure → Krysenix 2.4. It publishes a ≤20ms number; the LS100X describes low-latency, interference-free Game Mode without a millisecond figure.
• Best for crowded Wi-Fi environments → LucidSound LS100X. It's specifically engineered to hold a strong connection in busy wireless conditions.
• Best for competitive positional audio → LucidSound LS100X. Its FPS EQ mode plus Windows Sonic spatial sound are aimed squarely at hearing enemies first.
• Best for travel and packing → Krysenix 2.4. The foldable frame saves space; the LS100X ships with a carrying case but isn't described as foldable.
• Best for chat flexibility → LucidSound LS100X. The detachable boom mic with LED mute indicator plus a built-in backup mic is a genuinely useful redundancy.
• Best for a physical-button feel → Krysenix 2.4. Push-button controls versus the LS100X's touch controls — pure preference, but it matters to some players.
In my opinion, the LucidSound LS100X is the set I'd buy for low-latency gaming, mainly because it solves the two things that ruin long sessions: battery anxiety and a dropped wireless link. The 72-hour Game Mode and up-to-130-hour Bluetooth figures, the interference-resistant USB-adapter connection, and the FPS EQ with Windows Sonic make it the more complete gaming tool — provided you're on Xbox or happy with its Bluetooth side.
I'd steer to the Krysenix 2.4 if you're on PC, PlayStation, Switch or Mac and want a low-latency 2.4GHz dongle with a published ≤20ms rating and a foldable, RGB-lit body. Just remember it won't work with Xbox, and the mic isn't compatible in every mode. Either way, check the current price on Amazon before you commit, since that's the one thing these spec sheets can't tell you.
Low latency headphones minimize the delay between the audio source and what you hear. The Krysenix 2.4, for example, uses 2.4GHz lossless wireless rated at ≤20ms to keep sound in sync with on-screen action, while the LucidSound LS100X uses a USB-adapter Game Mode described as low-latency and interference-free.
Lower is better, and anything under roughly 20–30ms tends to feel in sync for gaming. Krysenix publishes a ≤20ms figure for its 2.4GHz mode; LucidSound doesn't list a millisecond number but markets its Game Mode as low-latency specifically to reduce chat lag and audio desync.
The LucidSound LS100X is a wireless gaming headset for Xbox Series X|S, so yes. The Krysenix 2.4 is not compatible with Xbox in either 2.4GHz or Bluetooth mode, so Xbox players should go with the LucidSound.
LucidSound wins on raw endurance: up to 130 hours over Bluetooth or up to 72 hours in Game Mode. Krysenix offers up to 50 hours with RGB off or 30–35 hours with RGB on from its 1200mAh battery, which charges in 2.5 to 3 hours.
