If you want to protect and carry a pair of ASUS ROG Cetra True Wireless SpeedNova earbuds without scratching or losing the case, choose DAYJOY 2; if you need a complete wired gaming headset with a detachable boom mic, choose Olnverath G6.
• DAYJOY 2 — biggest strength: a two-pack of soft silicone sleeves with a charging cutout, so you can charge the earbuds without pulling the cover off. Biggest trade-off: it is a case only, so you still need to own the ASUS ROG Cetra earbuds (and it fits those models specifically).
• Olnverath G6 — biggest strength: a full wired in-ear headset with a detachable boom mic plus a built-in inline mic, so it covers gaming chat and everyday calls out of the box. Biggest trade-off: it is wired with a 3.5mm jack, so you need a device with that port (or an adapter).
• Who DAYJOY 2 is for: owners of ASUS ROG Cetra True Wireless / SpeedNova earbuds who want drop protection, grip and a carabiner carry option.
• Who Olnverath G6 is for: someone who wants one affordable wired headset for PC or phone gaming, calls and music without charging anything.
• The core difference: one is an accessory that protects hardware you already own; the other is the hardware itself.
The DAYJOY 2 is a two-pack of soft silicone protective cases with carabiner keychains, made specifically for the ASUS ROG Cetra True Wireless Gaming Earbuds and the ASUS ROG Cetra True Wireless SpeedNova Gaming Earbuds. The fit is not universal — the silicone is shaped around those two charging cases, so it will not stretch usefully over a random pair of earbuds. If you own either of those models, this is the kind of accessory that quietly earns its keep.
You also get two covers — one black, one blue — plus two keychains, so you can rotate the look or keep one as a spare. The trade-offs are honest ones. There's no warranty listed, and a silicone sleeve will never feel like a rigid hard shell. It's also strictly a protector: it adds no sound, no features and no battery. If you don't already own the compatible Cetra earbuds, this product has nothing for you. If you do own them and you're tired of a bare, slippery case rattling around, it's a sensible pickup.
Olnverath G6: Who It's For
The Olnverath G6 is a different animal entirely — a wired in-ear gaming headset with a 3.5mm jack and a dual-microphone design. The headline feature is the detachable boom microphone: clip it on for game chat, pull it off and the headset works like a normal pair of earphones with the built-in inline mic handling calls. That flexibility is genuinely useful, because most wired gaming buds force you to live with a mic arm hanging off your face even when you're just listening to music on the bus.
Sound-wise, the design brief points at a punchy, bass-forward tuning — the kind that suits game effects, movies and music where you want some weight behind the low end. The 1.2 m cable is a normal desktop length: plenty of slack to reach a PC tower or a laptop, short enough not to tangle into a mess. The housing is ABS with TPE, which keeps the buds small and light — around 0.02 kg for the headphone itself — so they sit in the ear rather than weighing on it, and the ergonomic shape is aimed at staying put during sport or long sessions.
Compatibility is the simple part: anything with a 3.5mm jack, which covers most PCs, laptops and phones. The catch is the flip side of that simplicity — no jack means no G6, so USB-C-only phones and consoles without a headphone port need an adapter. There's also no wireless mode and no charging case, and the package is a single headphone with no carry pouch listed. If you want zero-latency wired audio for gaming and calls on a PC or a phone with a headphone port, the G6 is built for exactly that.
• Best for protecting ASUS ROG Cetra earbuds → DAYJOY 2. It's cut for those two models and nothing else.
• Best for a complete, ready-to-use headset → Olnverath G6. It's the actual earphones, mic included.
• Best for charging convenience → DAYJOY 2. The bottom cutout lets you charge with the sleeve on.
• Best for gaming voice chat → Olnverath G6. The detachable boom mic with noise reduction is purpose-built for in-game comms.
• Best for carrying around → DAYJOY 2. The carabiner clips to a bag for running, hiking or commuting.
• Best for portability with no battery worries → Olnverath G6. Wired means nothing to charge, ever.
• Best for device flexibility → Olnverath G6, as long as your device has a 3.5mm jack.
• Best for a spare or a second color → DAYJOY 2, since the pack includes two covers and two keychains.
These two barely compete — they solve opposite problems. If I owned ASUS ROG Cetra True Wireless SpeedNova earbuds, I'd buy the DAYJOY 2, because a two-pack of grippy silicone sleeves with a charge cutout and a carabiner is cheap insurance for a case I'd otherwise scratch and misplace. If I needed a headset to actually play and talk with, I'd buy the Olnverath G6, because the detachable boom mic plus inline mic covers gaming and calls without any charging routine. In my opinion, the G6 is the better pick for most people starting from zero, and the DAYJOY 2 is the better pick for anyone who already owns the Cetra earbuds.
FAQ
The G6 uses a 3.5mm wired connection, so it needs a device with that port. USB-C-only phones and consoles without a headphone jack will need an adapter, since there's no wireless option.
For actual gaming audio and voice chat, the Olnverath G6 — it's a headset with a detachable noise-reducing boom mic and a built-in inline mic. The DAYJOY 2 adds no audio at all; it just protects a case.
