• Ulian's biggest strength: an open-ear hook design with a detachable noise-cancelling boom mic plus a built-in mic, so you get breathable comfort and two ways to talk.
• Ulian's biggest trade-off: it's an open-ear design with no active noise control, so it won't block out the room around you, and battery life is rated at 10 hours per charge.
• Monster Mission 300's biggest strength: 7.1 surround sound with positional audio cues and RGB ambient lighting, backed by a 48-hour battery rating.
• Monster Mission 300's biggest trade-off: 2.4GHz ultra-low latency is the headline mode, but the spec sheet lists Bluetooth as the wireless technology and Bluetooth 4 as the version — so I'd treat the 2.4GHz dongle question as one to verify before buying.
• Who each is for: Ulian suits all-day comfort seekers, glasses wearers, and gamers who want to hear their room; Monster suits players who want immersion, surround staging, and a long battery rating over ear-canal comfort.
The Ulian headphone is built around one idea: keep your ears open. Instead of sealing a cup over or into your ear, it hangs from a silicone ear hook, so your ear canal stays clear and air moves freely. That matters more than it sounds. If you've ever pulled off a headset after a long session and felt that hot, damp, itchy feeling, the open-ear hook design is aimed squarely at you. Ulian also states the design protects your hearing and keeps ears clean and dry — reasonable claims for a set that never plugs the canal.
Audio-wise, you're working with a 32-ohm impedance and a 20 Hz – 20,000 Hz frequency range, and Ulian describes the tuning as bright, with the goal of making in-game sound effects easy to pick out. It's a stereo presentation, not a surround format, so positional accuracy comes from the tuning rather than a virtual 7.1 processor. Connection options are unusually broad for the category: a 2.4GHz USB dongle, a 2.4GHz Type-C dongle, and Bluetooth 5.4, covering PS5, PS4, Switch, PC, laptops, phones, and tablets. Xbox buyers should check their model's compatibility with the 2.4GHz USB/Type-C dongle before ordering — Ulian flags that explicitly.
The mic setup is the other standout. There's a detachable boom mic with noise reduction for clear in-game chat, and removing it puts the headset into mute mode — a physical, obvious mute. There's also a built-in microphone, so you keep voice capability even with the boom detached. Charging runs on a magnetic cable, takes about 1.5 hours, and Ulian rates play time at up to 10 hours with over 110 hours of standby. IPX5 water resistance means sweat is fine, which is why Ulian pitches it for gaming, working, relaxing, exercising, cycling, and climbing.
Monster Mission 300: Who It's For
The Monster Mission 300 takes the opposite approach. This is an over-ear headset with plastic, silicone, and fabric construction and touch controls, and it's aimed at immersion first. The headline feature is 7.1 surround sound, which creates a wider, more detailed 3D stage so you can place footsteps, gunshots, and directional cues more accurately. For competitive shooters, that's the reason to pick this over the Ulian — surround staging is a different tool than bright stereo.
The second headline is latency. Monster rates 2.4GHz mode at under 20ms, which is the range where audio stays in sync with what you're seeing. Note the connectivity listing here: Bluetooth is the stated wireless technology with Bluetooth 4 as the version, so if you specifically need the 2.4GHz dongle path, confirm exactly what's in the box for your console or PC before you commit.
Then there's the lighting. Dynamic RGB effects sync with your gameplay, which is purely cosmetic — but if you stream, record, or just like a setup that looks alive at night, it's a real feature, not filler. Monster also lists a 3.5mm jack, so wired use is an option alongside wireless, and the audio side uses a dynamic driver with a 20 Hz – 20,000 Hz range.
Battery is where Monster separates itself: the spec sheet lists a 48-hour average battery life and a 48-hour charge time. Read that carefully — the two figures match, which is unusual and worth clarifying with the seller, since a 48-hour charge time for a 48-hour runtime is a strange pairing. Either way, the rated runtime is far longer than the Ulian's 10 hours. Monster also leans hard on after-sales support, promising dedicated service for every customer, and includes a 1-year manufacturer warranty.
Buy it if you want surround sound, positional audio, RGB flair, wired-or-wireless flexibility, and a long battery rating. Skip it if you hate on-ear or over-ear pressure, want to hear your surroundings, or need a detachable boom mic and a guaranteed hardware mute.
Side-by-Side: Which Should You Choose?
• Best for surround and positional audio → Monster Mission 300. 7.1 surround is the whole point of this headset; the Ulian is stereo.
• Best for battery rating → Monster Mission 300. 48 hours rated versus 10 hours on the Ulian.
• Best for chat control → Ulian Gaming Headphone. Detachable boom mic with physical mute mode, plus a built-in mic as backup. Monster lists no microphone spec at all.
• Best for device flexibility → Ulian Gaming Headphone. 2.4GHz USB dongle, 2.4GHz Type-C dongle, and Bluetooth 5.4, with PS5, PS4, Switch, PC, mobile, and tablet support.
• Best for sweat and movement → Ulian Gaming Headphone. IPX5 water resistance and a hook fit that stays put during exercise or cycling.
• Best for wired fallback → Monster Mission 300. It has a 3.5mm jack; the Ulian has no jack at all.
• Best for setup aesthetics → Monster Mission 300. RGB ambient lighting synced to gameplay.
In my opinion, the right pick depends entirely on what's ruining your current sessions. If it's ear fatigue, heat, or a mic you can't trust, I'd buy the Ulian Gaming Headphone — the open-ear hook, the detachable mic with a real mute, and the triple connection options solve practical problems that RGB never will. If your problem is that you can't hear where enemies are coming from and you're tired of charging every night, I'd buy the Monster Mission 300 for its 7.1 surround and long battery rating. For most people who game for hours and want to stay comfortable and clearly heard, the Ulian is the one I'd put on my own head. Check the current price on Amazon for both before deciding — the numbers move, and value matters here.
FAQ
The spec sheet doesn't list a microphone for the Mission 300, so if voice chat is essential, confirm with the seller before buying. The Ulian, by contrast, ships with a detachable noise-cancelling boom mic plus a built-in mic.
Ulian says the headset works with Xbox but warns that Xbox users should verify their specific model supports the 2.4GHz USB or Type-C dongle first. Compatibility varies by Xbox model, so check before ordering.
By the ratings, the Monster Mission 300 at 48 hours versus the Ulian at 10 hours. The Ulian does charge faster — about 1.5 hours — and offers over 110 hours of standby, so it's the easier one to top up between sessions.
