• Sony IER-EX15C — biggest strength: USB-C plug-and-play with zero battery, zero latency and zero pairing, plus an in-line remote with volume, a multi-function button and a built-in mic.
• Sony IER-EX15C — biggest trade-off: It's a passive in-ear design with no active noise cancellation, and it only works with USB-C / USB Audio Class 1.0 devices.
• AOC Gaming Headset — biggest strength: 50mm dynamic drivers, over-ear cushions, static RGB lighting and a USB-A plug-and-play connection aimed at PC and console gaming.
• AOC Gaming Headset — biggest trade-off: It's a wired USB-A headset weighing in at 12.8 ounces, it's not compatible with Xbox, and the Switch support only works in docked mode.
• Pick Sony IER-EX15C if you want something tiny, tangle-resistant and travel-friendly for music, calls and casual listening on a phone or laptop.
• Pick AOC Gaming Headset if you want a dedicated over-ear headset for long PC or PlayStation sessions with a proper boom mic.
The IER-EX15C is Sony's take on the simplest possible headphone: a wired USB-C in-ear with no battery to charge and no Bluetooth to fight with. You plug it into a USB-C port — phone, laptop, tablet, handheld console — and it just works, provided the device supports USB Audio Class 1.0. That's the whole pitch, and for a lot of people it's exactly what they want. No pairing menus. No "connected" chime. No dead earbud at the worst moment.
Sound-wise, Sony describes a compact dynamic driver paired with a high-compliance diaphragm, tuned to keep the housing light while still reproducing punchy bass and clear vocals. The frequency range is listed at 20Hz–20,000Hz, which is the standard full-range spread. In practice that means it's a generalist tuning — fine for pop, podcasts, YouTube and calls, not a specialist monitor. The in-line remote handles volume up/down, play/pause, track skipping, call answering, voice assistant activation and mic mute, all from one small module on the cable. That mute/unmute function is genuinely useful on work calls.
Who should buy it: commuters, students, office workers and anyone who wants one pair of earbuds that lives in a bag and works instantly on a USB-C phone or laptop. Who should skip it: if you need active noise cancellation, a boom microphone, or compatibility with a device that only has USB-A or a 3.5mm jack, this isn't the right tool. It's also not the pick for marathon gaming sessions — an in-ear with a cable remote is the wrong form factor for that.
AOC Gaming Headset: Who It's For
The AOC ACG2510 is unapologetically a gaming headset. The headline spec is a pair of 50mm dynamic drivers — physically large for a headset at this tier — with a stated frequency response of 20Hz–20,000Hz and 110dB±3dB sensitivity at 16 ohms impedance. Big drivers and high sensitivity generally mean the headset gets loud easily and can push bass with some authority, which is why AOC frames it around "gaming explosions, music depth and vocal clarity." The microphone is spec'd at -56±3dB sensitivity, which is on the sensitive side — good for picking up your voice clearly in voice chat without shouting.
Setup is deliberately dumb-simple: it's a USB Type-A plug-and-play headset. Plug it into a PC or laptop and the system recognises it as both input and output automatically, no drivers. There's also a static RGB backlight running at DC5V±5% for the classic late-night desk glow. The cable is a 79-inch (roughly 2-meter) braided cord, reinforced against fraying, which gives you real slack to move around at a desk or lean back in a chair. The over-ear oval cushions and plastic enclosure keep it in the "comfortable for extended wear" category rather than the "premium materials" one.
Compatibility matters here and it's worth reading carefully. AOC lists PC, laptops, PS4, PS5, and Nintendo Switch in docked mode. It is explicitly not compatible with Xbox. That's a hard stop for Xbox players, and it's the single biggest caveat on this product. The switch to docked-mode-only for the Switch is the other one — handheld Switch players are out of luck.
Side-by-Side: Which Should You Choose?
• Best for portability → Sony IER-EX15C. In-ear, 0.05 kg, tangle-resistant cable and a cable adjuster. It disappears into a pocket. The AOC is a 12.8-ounce over-ear you'll leave on the desk.
• Best for gaming → AOC Gaming Headset. 50mm drivers, over-ear isolation, a dedicated boom mic and RGB. This is what it was built for.
• Best for phone and laptop calls → Sony IER-EX15C. The in-line remote gives you volume, call answer and one-touch mic mute without touching your device.
• Best for long desk sessions → AOC Gaming Headset. Over-ear cushions plus a 79-inch braided cable mean you can lean back and stay plugged in.
• Best for console flexibility → AOC Gaming Headset, but only if you're on PS4, PS5 or docked Switch. Xbox players should look elsewhere.
• Best for no-fuss, no-battery use → Sony IER-EX15C. Wired USB-C means no charging, no latency and no dropouts, ever.
• Best for fitting your own ears → Sony IER-EX15C. Three ear tip sizes (XS, M, XL) versus a fixed over-ear design.
• Best for style options → Sony IER-EX15C. Four colors (black, white, blue, pink) versus black only on the AOC.
• Best for a single device that never moves → AOC Gaming Headset. USB-A plug-and-play with automatic input/output recognition on PC.
If I had to buy one, I'd buy the Sony IER-EX15C — but only because my listening is mostly phone-and-laptop based and I value the grab-and-go simplicity of a wired USB-C in-ear with no battery to manage. In my opinion, it's the better everyday companion for the average person, and the tangle-resistant cable plus three tip sizes make it genuinely livable.
That said, if your primary use is PC or PlayStation gaming, the AOC is the correct answer and I wouldn't hesitate. The 50mm drivers, boom mic and over-ear comfort are built for exactly that, and the Sony simply isn't. Match the tool to the job.
FAQ
No — in my opinion the AOC is the better gaming pick. It has 50mm over-ear drivers, a dedicated boom microphone and a long braided cable. The Sony is an in-ear with an in-line remote, which is fine for casual play but not designed for competitive gaming.
Neither one. Both are wired — the Sony via USB-C and the AOC via USB Type-A. There's nothing to charge, which also means no latency and no dropouts. That's the main appeal of wired audio in 2026.
No. AOC states the ACG2510 is compatible with PC, laptops, PS4, PS5 and Nintendo Switch in docked mode, but it is not compatible with Xbox. If you're on Xbox, skip this one.
Think about where you'll use it. In-ear (Sony) wins for commuting, phone calls and travel — it's tiny, light and fits in a pocket. Over-ear (AOC) wins for sitting at a desk or couch for hours, where bigger drivers and a boom mic matter more than portability.
