• Ulian Gaming Headphone — biggest strength: True low-latency 2.4GHz USB and Type-C dongle connection plus Bluetooth 5.4, wrapped in a lightweight open-ear hook design that never seals your ear canal.
• Ulian Gaming Headphone — biggest trade-off: Short 10-hour battery life and no 3.5mm jack, so wired fallback isn't an option.
• Globalsades Defender — biggest strength: A massive 1050mAh battery rated for up to 45.5 hours in Bluetooth mode, backed by 50mm drivers and RGB lighting.
• Globalsades Defender — biggest trade-off: Bluetooth 5.3 tops out below the Ulian's 5.4, and the over-ear build is heavier than an open-ear hook.
• Who each pick is for: Ulian for marathon gamers who want low latency and breathable comfort; Globalsades Defender for players who want long battery life, deep bass and a classic over-ear feel.
The Ulian Gaming Headphone is built around one idea: keep latency low and keep your ears open. Its headline feature is the upgraded low-latency connection that runs over a 2.4GHz USB dongle or a Type-C dongle, which is the setup most competitive players reach for when they want the tightest possible audio response. On top of that it supports Bluetooth 5.4, so you can swap to a phone or tablet without juggling cables. There is no headphone jack at all, which tells you Ulian wants you living in wireless mode.
The design is the other half of the story. It uses an open-ear hook made from skin-friendly silicone that sits over your ear rather than sealing the canal. That means stronger breathability than traditional headphones, less heat buildup, and ears that stay dry through long sessions. If you've ever pulled off a sealed headset after three hours and felt like your ears were cooking, this is the alternative Ulian is offering.
Audio-wise it covers 20Hz–20kHz at 32 ohm, and the detachable boom mic doubles as a mute switch — install it to talk, pop it off to go silent. There's also a built-in mic, so you get two ways to communicate. An IPX5 rating means sweat won't kill it, which opens the door to workouts and cycling, not just gaming. It charges in 1.5 hours for up to 10 hours of play, with over 110 hours of standby.
Buy it if you want low latency, an open-ear fit and a mic you can physically remove. Skip it if you need all-day battery or a wired 3.5mm option — 10 hours is the ceiling here, and there's no jack to fall back on.
The Globalsades Defender takes the opposite approach: more battery, more driver, more immersion. Its 1050mAh rechargeable battery is rated for up to 45.5 hours of playtime in Bluetooth mode, which is the kind of number that lets you stop thinking about charging entirely. Pair that with 50mm dynamic drivers and you get a fuller, bass-forward sound than a small open-ear hook can physically produce. If you play cinematic single-player games or watch movies between matches, the Defender is tuned for that job.
Connectivity is broad in a different way. It runs Bluetooth 5.3 with up to 10m of range, plus a 2.4G USB transmitter for low-latency wireless, and it also carries a 3.5mm jack for wired use. That wired option matters if you ever want zero-latency audio or a dead-battery rescue. The detachable microphone handles chat, streaming and calls, and there are built-in controls for volume and audio management without leaving your game.
The trade-offs are real, though. Bluetooth 5.3 is a step behind the Ulian's 5.4, so expect slightly older wireless efficiency. The over-ear design with soft cushions is comfortable but heavier — listed at 11.36 ounces — and it uses passive noise cancellation rather than active processing. RGB lighting gives it a gaming look, though that's atmosphere, not performance. Sensitivity is rated at 121dB with 20 ohm impedance, which means it's easy to drive.
Buy it if you want huge battery life, deep bass from 50mm drivers, and the flexibility of wired or wireless. Skip it if you want an open-ear fit or the newest Bluetooth version.
Side-by-Side: Which Should You Choose?
• Best for low latency → Ulian Gaming Headphone. Its 2.4GHz USB and Type-C dongle plus Bluetooth 5.4 is the more latency-focused setup of the two.
• Best for battery life → Globalsades Defender. Up to 45.5 hours versus the Ulian's 10 hours is not close.
• Best for bass and immersion → Globalsades Defender. 50mm drivers move more air than a small open-ear hook.
• Best for wired backup → Globalsades Defender. It has a 3.5mm jack; the Ulian has none.
• Best for workouts and sweat → Ulian Gaming Headphone. IPX5 waterproofing is a feature the Defender doesn't list.
• Best for switching between console, PC and phone → Ulian Gaming Headphone. PS5, PS4, Xbox, Switch, PC, phone and tablet support via dongle or Bluetooth.
• Best for a traditional gaming look → Globalsades Defender. RGB lighting and over-ear cups read as classic gaming gear.
If I were buying for competitive play, I'd take the Ulian Gaming Headphone. The 2.4GHz dongle path, Bluetooth 5.4 and open-ear design are all pointed at the thing that actually matters in a firefight — hearing footsteps the instant they happen without your ears overheating. The 10-hour battery is the price of that openness, and I can live with it.
The Globalsades Defender is the better pick if you want to charge once a week and feel every explosion through 50mm drivers. In my opinion, most players chasing low latency should start with the Ulian, and heavy single-player or movie watchers should lean Defender. Either way, check the current price on Amazon before deciding, since that's the one number that can tip a close call.
Low latency headphones minimize the delay between the audio source and what you hear, so game audio stays synced with on-screen action. Both headsets here target that with 2.4GHz USB transmitters, and the Ulian adds Bluetooth 5.4 while the Defender uses Bluetooth 5.3.
For gaming, you want delay low enough that you can't perceive a gap between action and sound — 2.4GHz dongle connections are the standard way to get there. The Ulian's 2.4GHz USB/Type-C dongle and the Defender's USB transmitter both exist specifically to deliver that faster response.
The Ulian lists compatibility with PS5, PS4, Xbox, Switch, PC, phones and tablets, though Xbox buyers should confirm their model supports the 2.4GHz USB or Type-C dongle. The Defender is listed as compatible with consoles, Switch and mobile, and it adds a 3.5mm wired option for devices that need it.
The Globalsades Defender wins comfortably, rated for up to 45.5 hours in Bluetooth mode from its 1050mAh battery. The Ulian charges in 1.5 hours and provides up to 10 hours of playtime, with over 110 hours of standby.
