If you want a true multi-device gaming headset with a boom mic, ultra-low 20 ms wireless latency and a huge 60-hour battery, choose Fachixy Gaming Headset; if you need tiny, ultra-light sleep earbuds with hybrid ANC that blocks up to 98% of noise, choose Ertuly T33.
• Fachixy Gaming Headset — biggest strength: over-ear design with 50 mm titanium-coated dynamic drivers, 2.4GHz dongle plus Bluetooth 5.4, ENC boom mic and up to 60 hours of playtime.
• Fachixy Gaming Headset — biggest trade-off: it's a 280 g full-size headset that does not support Xbox at all, and the mic only works in dongle mode on Switch.
• Ertuly T33 — biggest strength: ≈3 g per bud, hybrid ANC cutting up to 98% of noise, a sleep mode that mutes alerts, and IPX6 sweat resistance.
• Ertuly T33 — biggest trade-off: it's a Bluetooth earbud, not a gaming headset — no boom mic, no low-latency dongle, and only 8 hours per charge (48 hours with the case).
• Pick Fachixy if you play on PS5, PS4, PC or Switch and want one headset for chat, streaming and long sessions.
• Pick Ertuly T33 if you sleep on your side, travel, or need to shut out snoring and background noise without anything pressing on your ear.
The Fachixy VK81 is built around one idea: keeping audio locked to the screen. Its 2.4GHz USB/Type-C dongle runs at a claimed 20 ms latency, which is the slowest-sounding number you'd ever want to see and, in practice, means footsteps, reloads and ability cues land when they happen rather than a beat later. The 50 mm dynamic drivers with a 32 ohm impedance are tuned for a big, bass-forward 3D stereo presentation, so it suits FPS, RPG and open-world games where you want to feel the low end.
Connectivity is the other headline. You get 2.4GHz wireless for PC, PS5, PS4, Mac, laptops and Switch, plus Bluetooth 5.4 for phones and tablets within a 10 m range. The boom mic uses ENC noise cancelling to cut background sound, and it's flexible, so you can park it where your mouth actually is. The whole thing folds for storage, the RGB lighting can be switched off if you'd rather not glow, and the battery is rated up to 60 hours — with a 48-hour average figure listed — so charging is a weekly chore rather than a nightly one.
Who should buy it: anyone who wants one headset for console and PC gaming, voice chat, streaming and video, and who values long battery life over portability. Metal-and-plastic construction and a 280 g over-ear fit mean it's a sit-down-at-your-desk product. Who should skip it: Xbox owners, full stop — Xbox One and Series X|S aren't supported because Microsoft's proprietary audio path doesn't accept a standard 2.4GHz dongle or Bluetooth. Skip it too if you game on Switch over Bluetooth and need the mic; on Switch the microphone only works in dongle mode. And if you want something to wear in bed, a 280 g over-ear headset is the wrong shape entirely.
The Ertuly T33 is a completely different animal, and it's honest about it. It's a sleep-first earbud: each bud weighs roughly 3 g, the shape is ultra-thin and in-ear, and it's specifically designed so side sleepers don't get a pressure point against the pillow. The glossy black plastic build and soft ear tips keep it light, and the compact charging case makes it a genuinely pocketable travel item.
Its core feature is hybrid ANC with dual microphones, rated to neutralize up to 98% of disruptive sound — snoring, traffic, appliance hum. A triple tap flips between ANC and Transparency mode, so you can seal yourself off or let the world back in without taking the buds out. There's also a sleep mode triggered by four quick taps that mutes all alerts and blocks accidental touch input, which is exactly the thing that ruins sleep earbuds for people who roll around at night.
Audio is handled by 13 mm dynamic drivers with a 38 ohm impedance and a balanced, bass-rich tuning — pleasant for music and podcasts, not a positional-audio gaming tool. Bluetooth 6.0 gives a stable 10 m connection with instant pairing when you open the case, and ENC microphones keep calls clear. You get about 8 hours per charge and 48 hours total with the case, recharged in 1.5 hours over USB-C, with an LED indicator on the case so you know where you stand. IPX6 means sweat and splashes are fine. You can use both buds in stereo or either one solo for calls.
Who should buy it: side sleepers, light sleepers, frequent flyers, commuters and anyone who wants a near-invisible earbud for work calls and workouts. Who should skip it: competitive gamers. There's no dongle, no boom mic and no low-latency gaming mode here — the T33 is about quiet and comfort, not about hearing a reload two rooms away.
• Best for console and PC gaming → Fachixy Gaming Headset. 2.4GHz dongle, 20 ms latency, 50 mm drivers, boom mic.
• Best for sleep and side sleeping → Ertuly T33. ≈3 g per bud, ultra-thin shape, sleep mode that mutes alerts.
• Best for battery life in one sitting → Fachixy Gaming Headset. Up to 60 hours on a charge versus 8 hours per bud on the T33.
• Best for noise cancelling → Ertuly T33. Hybrid ANC rated to block up to 98% of noise; the Fachixy relies on passive sound isolation instead.
• Best for voice chat while gaming → Fachixy Gaming Headset. The adjustable ENC boom mic is the right tool; the T33 has ENC call mics but no boom.
• Best for travel and pockets → Ertuly T33. Tiny buds plus a compact USB-C case, versus a foldable but still full-size 280 g headset.
• Best for workouts and sweat → Ertuly T33. IPX6 protection; the Fachixy has no water-resistance rating listed.
• Best for Xbox owners → neither. The Fachixy explicitly doesn't support Xbox, and the T33 is a Bluetooth earbud built for sleep and calls.
• Best for phone and tablet audio → Ertuly T33. Bluetooth 6.0 auto-pairing is simpler than the Fachixy's Bluetooth 5.4 mobile mode, though both work.
In my opinion, these two barely compete — they solve different problems, so the honest answer is to buy based on your main use. If you're a gamer on PS5, PS4, PC or Switch, I'd take the Fachixy Gaming Headset: the 2.4GHz low-latency link, the boom mic and the up-to-60-hour battery are the three things a gaming headset has to get right, and it gets all three. If your problem is noise at night, I'd take the Ertuly T33 every time — 3 g buds, 98% ANC and a sleep mode that kills alerts are exactly what a bad sleeper needs, and no over-ear headset can replace that. Only buy one if your needs are genuinely one-sided.
Neither is "better" overall — they're different categories. Fachixy is a gaming headset with a dongle, boom mic and up to 60 hours of battery. Ertuly T33 is a sleep earbud with hybrid ANC, IPX6 and 48 hours total with its case.
Yes. It connects over 2.4GHz USB or Type-C to PS5, PS4, PC, Mac, laptops and Switch, and over Bluetooth 5.4 to phones and tablets. It does not support Xbox consoles, and the mic only works in dongle mode on Switch.
You can use it for casual audio, but it's not a gaming earbud. It's Bluetooth-only with no low-latency dongle and no boom mic, so it can't match the Fachixy's 20 ms 2.4GHz connection for competitive play.
The Ertuly T33 is the one designed for that — its dual-mic hybrid ANC is rated to neutralize up to 98% of noise like snoring and traffic, and a triple tap switches to Transparency mode. The Fachixy uses passive sound isolation, which reduces some outside noise but isn't active cancellation.
