How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a single wireless headset that covers consoles, PC and mobile with an open-ear fit you can wear for hours, choose Ulian Gaming Headphone; if you need maximum passive isolation and a wired, serviceable in-ear monitor built for competitive positional audio, choose KZ Axas HiFi Gaming.
• Ulian's biggest strength: true wireless freedom across 2.4GHz USB, 2.4GHz Type-C and Bluetooth 5.4, plus a detachable noise-cancelling boom mic and an open-ear design that keeps your ear canal clear.
• Ulian's biggest trade-off: open-ear means almost no passive isolation, and its noise control field is listed as "None" — you'll hear your room, your keyboard and your fan.
• KZ Axas's biggest strength: 37dB of passive isolation from a deep in-ear seal, a 10mm dynamic driver tuned with controlled bass and a boosted upper-mid range so footsteps and reload cues sit forward in the mix.
• KZ Axas's biggest trade-off: it's wired only, with a 3.5mm jack and a 3.96ft detachable silver-plated cable. There's no battery, no dongle and no Bluetooth of its own.
• Pick Ulian if you want one headset for PS5, PS4, Switch, PC, tablet and phone with no cable tether.
• Pick KZ Axas if you play competitive shooters in a noisy room and want isolation plus wired reliability.
The Ulian is a wireless open-ear gaming headphone, and its whole identity is flexibility. You get three ways to connect: a 2.4GHz USB dongle, a 2.4GHz Type-C dongle, and Bluetooth 5.4. That means one headset can follow you from a PS5 to a laptop to a phone without swapping gear. Ulian explicitly notes that Xbox owners should confirm their model supports the 2.4GHz USB or Type-C dongle before buying, which is the honest way to frame console compatibility.
The detachable boom mic is the feature I'd point at first. Install it and you get voice pickup with noise reduction for clearer in-game comms; pull it off and the headset drops into mute mode, with a built-in mic still available as a backup. That dual-mic setup is genuinely useful if you switch between squad chat and solo play.
The open-ear hook design is the other defining trait. The silicone ear hooks sit around your ear rather than sealing the canal, so air moves, your ears stay dry, and there's no pressure build-up over a long session. Ulian rates it IPX5 for sweat, and the battery runs up to 10 hours on a 1.5-hour charge, with over 110 hours of standby. At 32 ohm impedance and 20Hz–20,000Hz, the tuning is a general-purpose profile rather than a specialist one.
KZ Axas HiFi Gaming: Who It's For
The KZ Axas is a wired in-ear monitor, and it's built around a very different priority: focus. KZ states 37dB of passive isolation from the deep in-ear seal and the included tips — a figure that reflects how much outside noise an IEM can block when it's seated properly. In a room with a loud PC, a fan or traffic outside, that's the difference between hearing a footstep and hearing nothing but your own case fans.
The sound profile is deliberate. KZ describes tuning developed with professional esports players, with brilliant highs, precise spatial imaging, a slightly boosted upper-mid range so reload sounds pop, and controlled bass that lets footsteps separate from explosions. The 10mm dynamic driver, 20 ohm impedance, 107dB sensitivity and 20Hz–20,000Hz range describe a set that's easy to drive from a controller, a phone or a laptop jack without extra amplification.
Physically, it's an ear-hook IEM with a detachable 3.96ft silver-plated cable, and a 3.2ft extension in the box. Because the cable detaches, it's compatible with KZ Bluetooth modules if you later want to go wireless, and every part is described as serviceable rather than disposable. KZ backs it with a three-year warranty. The 3.5mm jack means it works with anything that has a headphone port, plus USB-C devices via the appropriate option — no dongle required for modern iPhones, iPads, Samsung, Google, Motorola or OnePlus hardware.
Who should buy it: competitive players who want isolation, positional clarity and a wired connection that never needs charging. Who should skip it: anyone who wants wireless freedom, a boom mic for voice chat, or an open-ear feel — the Axas has none of those.
Side-by-Side: Which Should You Choose?
• Best for maximum isolation → KZ Axas HiFi Gaming. 37dB of passive isolation is the headline number here.
• Best for multiplatform flexibility → Ulian Gaming Headphone. PS5, PS4, Xbox (dongle permitting), Switch, PC, phone and tablet, plus Bluetooth 5.4.
• Best for competitive positional audio → KZ Axas HiFi Gaming. Boosted upper-mids and controlled bass are tuned to make cues stand out.
• Best for long sessions without ear fatigue → Ulian Gaming Headphone. Open-ear hooks and IPX5 sweat resistance keep ears dry and pressure-free.
• Best for zero charging hassle → KZ Axas HiFi Gaming. Wired means no battery, no 1.5-hour charge cycle, no 10-hour ceiling.
• Best for voice chat → Ulian Gaming Headphone. The detachable noise-reducing boom mic plus built-in backup mic is the more complete comms setup.
• Best for repairability → KZ Axas HiFi Gaming. Detachable cable, serviceable parts and a three-year warranty.
In my opinion, most people shopping for a low-latency gaming headphone should buy the Ulian Gaming Headphone. The 2.4GHz dongle connections are the whole point of the category, and Ulian bundles two of them plus Bluetooth 5.4, a removable noise-cancelling mic and an open-ear fit that stays comfortable past the ten-hour mark. I'd only steer you to the KZ Axas HiFi Gaming if isolation and positional accuracy matter more to you than wireless convenience — for example, if you play ranked shooters in a noisy room. Both are good at what they target; they just target different players.
what are low latency headphones
Low latency headphones are built to minimize the delay between the audio source and what you hear. In gaming, that delay is what makes footsteps, gunshots and voice chat feel out of sync with the screen. Both products here address it differently: the Ulian uses 2.4GHz USB and Type-C dongles plus Bluetooth 5.4 for a stable, ultra-low-latency wireless link, while the KZ Axas avoids the problem entirely with a wired 3.5mm connection.
how much low latency is good for gaming headphones
There's no single published number that fits every product, and neither data sheet quotes a millisecond figure. What matters is the connection type: a wired 3.5mm link like the KZ Axas has no wireless transmission step at all, and a dedicated 2.4GHz dongle like the Ulian's is designed specifically for lag-free play, unlike general-purpose Bluetooth audio.
No. Its noise control field is listed as "None," and the open-ear hook design deliberately leaves your ear canal unblocked for breathability. It reduces noise on the microphone side, not on what you hear coming in.
That depends on what tires you out. The Ulian's open-ear silicone hooks avoid pressure and heat, and it runs up to 10 hours per 1.5-hour charge. The KZ Axas uses in-ear tips that seal deeply — great for isolation, but you'll want to check tip fit for comfort over hours.
Yes. It uses a 3.5mm jack, so it works with PS4, PS5, Xbox, PC, laptops and tablets, and KZ notes USB-C options work with modern iPhones, iPads and Android phones without a dongle.
