If you want a complete, cable-and-go in-ear gaming headset that turns any 3.5 mm device into a gaming rig, choose ASUS ROG Cetra II; if you need a broadcast-quality boom mic that clips onto the headphones you already love, choose Antlion Audio ModMic Uni 2+. These two products sit on opposite sides of the same problem — one gives you sound in your ears, the other gives you a voice on the wire — and picking wrong means buying something that never solves the job you actually have.
• ASUS ROG Cetra II — biggest strength: A self-contained wired in-ear headset with ASUS Essence dynamic drivers made of liquid silicone rubber, a wide 20 Hz–40 kHz frequency range, and a 90° angled 3.5 mm connector built for handheld and console play.
• ASUS ROG Cetra II — biggest trade-off: It's a headset, not a microphone upgrade, and fit is everything — ASUS itself notes that mismatched earbud tips or a loose seal can change both sound quality and call performance. It's also a wired, passive-only design with no active noise cancellation.
• Antlion Audio ModMic Uni 2+ — biggest strength: It converts headphones you already own into a headset. Uni-directional, noise-cancelling capsule, in-line analog mute switch, 2 m integrated cable, and a patented neodymium N45 magnetic clasp system that lets you detach the mic when you don't need it.
• Antlion Audio ModMic Uni 2+ — biggest trade-off: It makes no sound of its own. You need headphones first, and console use may require adapters that Antlion sells separately.
• Pick ASUS ROG Cetra II if you want one box, one cable, and audio + mic working on PC, Mac, PlayStation, Xbox, Switch and mobile without extra parts.
• Pick Antlion Audio ModMic Uni 2+ if you already have a favorite pair of headphones and want to add a serious voice channel to them.
The ROG Cetra II is the simpler answer to "I want to game on everything I own." It's a wired 3.5 mm in-ear headset — no dongle, no charging, no pairing. That single jack is why it works across PC, Mac, PS4, PS5, Xbox One, Switch and mobile devices. If you're the kind of player who hops between a console in the living room and a laptop at a desk, that universality is the whole point.
The audio story here is the ASUS Essence driver. It's a dynamic driver built with liquid silicone rubber, which ASUS says gives more stable speaker performance and especially strong bass. The rated frequency range runs 20 Hz to 40 kHz with 32 ohm impedance, so it's an easy load for a controller jack or a phone. The housing is aluminum — lightweight, scratch-resistant, and styled in the Moonlight White finish. There's a 90° cable connector, which is a genuinely thoughtful detail: on a handheld or a controller, the cable drops straight down instead of jutting out and snagging your hand. Noise control is passive, meaning the silicone tips physically block some outside sound rather than cancelling it electronically. Touch and push-button controls are listed for the headset, and it ships with a Moonlight White carrying case.
Who should buy it: players who want a compact, durable, single-cable headset for handheld, console and mobile gaming, and who like the idea of a low-profile in-ear instead of a bulky over-ear. Who should skip it: anyone who already owns great headphones and only needs a better mic, and anyone who wants active noise cancellation or a wireless setup — neither is here. Also skip it if you're unwilling to experiment with earbud tip sizes. ASUS explicitly warns that a poor fit or loose seal will drag down both sound and call quality, so budget a few minutes to find the right tip.
The ModMic Uni 2+ solves a different problem entirely: you love your headphones and you don't want to give them up. This is a detachable 3.5 mm microphone that attaches to your existing headphones via a patented neodymium N45 magnetic clasp system. A base clasp sticks to the headphone (Antlion includes a top clasp, two base clamps, two spare adhesives and an alcohol prep pad), and the mic snaps on and off magnetically. When you're done talking, you pull the mic off and your headphones go back to being headphones.
The part that matters for voice chat is the capsule. It's uni-directional and noise-cancelling, which is the right pattern for gaming — it favors the sound directly in front of it and rejects more of the room around it. Antlion describes it as broadcast-quality audio in a tiny package, and it includes a pop filter to tame plosives. There's an in-line analog mute switch on the integrated 2 m cable, so muting doesn't require diving into software. Connector is 3.5 mm auxiliary, and power comes from the cord — no battery.
The kit is unusually complete: the mic, pop filter, 2 m cable, hard travel case, two base clasps, five cable clips, two extra adhesives, the alcohol pad and a manual. Cable clips are a small thing that make a big difference in daily use, because a mic cable flopping across your lap gets old fast. Antlion also notes that for console gaming, adapters may be required and are sold separately — that's the one compatibility caveat worth planning for. Compatibility is listed for gaming consoles, laptops, headphones and PCs, which covers smartphones, tablets and VR too.
Side-by-Side: Which Should You Choose?
• Best for a one-box setup → ASUS ROG Cetra II. Headphones and mic in a single 3.5 mm package, no assembly, no extra parts.
• Best for upgrading headphones you already own → Antlion Audio ModMic Uni 2+. It exists purely to add a mic to existing cans.
• Best for multi-platform plug-and-play → ASUS ROG Cetra II. PC, Mac, PS4, PS5, Xbox One, Switch and mobile all run through the same 3.5 mm jack.
• Best for voice-chat clarity → Antlion Audio ModMic Uni 2+. A dedicated uni-directional, noise-cancelling capsule with a pop filter beats a headset mic sharing housing with a driver.
• Best for handheld and portable play → ASUS ROG Cetra II. The 90° connector and lightweight aluminum in-ear housing were designed around portable gaming comfort.
• Best for commuting or noisy rooms → ASUS ROG Cetra II. In-ear silicone tips plus passive noise cancellation block more ambient sound than any open-back headphone with a mic clipped on.
• Best for travel and storage → ASUS ROG Cetra II carries a Moonlight White case, while Antlion Audio ModMic Uni 2+ ships with a hard shell travel case and cable clips — both are travel-friendly, just for different gear.
• Best for flexibility over time → Antlion Audio ModMic Uni 2+. Move the magnet base between headphones and the mic follows; the Cetra II is one fixed headset.
My Verdict
It's a full wired in-ear headset. It carries the ASUS Essence dynamic driver for audio and is listed with touch and push-button controls, so both listening and voice are handled by the same 3.5 mm connection.
No. It's a detachable microphone only — it produces no sound itself. You attach it to headphones you already own using the magnetic clasp and adhesive system, then plug the 3.5 mm jack into your device.
The ASUS ROG Cetra II, on paper, because its 3.5 mm jack is listed for PS4, PS5, Xbox One and Switch directly. The ModMic Uni 2+ is listed for gaming consoles too, but Antlion notes adapters may be required and are sold separately, so check your console's mic input before buying.
Based on the specs, I'd expect the ModMic Uni 2+ to have the edge for voice, because it's a dedicated uni-directional, noise-cancelling capsule with a pop filter built for one job. The Cetra II's mic shares a compact in-ear body, and ASUS notes that fit and tip size affect call performance. For pure voice quality, the ModMic is the more specialized tool.
