How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a pocketable, noise-cancelling set of true wireless earbuds that disappear into small ears and travel everywhere with you, choose Sennheiser CX Plus In-Ear; if you need a full-size wireless gaming headset with a boom mic, room-filling spatial audio and week-long battery for marathon sessions, choose Corsair Void v2. Those are genuinely different jobs, which is why this comparison comes down to how and where you actually listen — and if small or hard-to-fit ears are your problem, the fit story matters more than any spec on paper.
• Sennheiser CX Plus In-Ear — biggest strength: a proper in-ear design with four ear adapter sizes, ANC, Transparent Hearing and up to 24 hours of total playtime. Biggest trade-off: it's earbuds, so there's no boom mic and no headband to spread weight.
• Corsair Void v2 — biggest strength: simultaneous 2.4GHz wireless plus Bluetooth, Dolby Atmos spatial audio, a noise-reducing mic and up to 70 hours of battery. Biggest trade-off: it's an over-ear headset, so it's bulky, not pocketable, and there's no wired jack.
• Team Sennheiser CX Plus In-Ear if you want music-first sound, active noise cancellation and something that stays put in small ears.
• Team Corsair Void v2 if you game across Xbox, PC, PlayStation and Switch and need voice chat to just work.
• In my opinion the deciding question is simple: do you need a microphone and spatial audio for games, or do you need discreet, comfortable earbuds for everything else?
The CX Plus is built around one idea: give you serious audio in the smallest possible package. Sennheiser's TrueResponse transducer sits at the heart of it, paired with Bluetooth 5.2 and support for AAC, aptX, aptX Adaptive and SBC. In plain terms, that codec list matters because it keeps latency and audio quality solid across both iPhones and Android phones, rather than locking you into one ecosystem. The frequency range runs from 5 Hz to 21,000 Hz, and there's a Bass Boost EQ preset in the Smart Control app if you like your low end pushed forward.
Where this pair earns its keep is fit and daily carry. The in-ear shape is lightweight, and Sennheiser includes ear adapters in four sizes — that's the detail that makes these a genuinely good candidate if you normally struggle to keep earbuds seated. Small ears and narrow ear canals are exactly the case where a fourth size option changes everything; a secure seal is also what makes Active Noise Cancellation actually work, because ANC on an in-ear depends on blocking the physical gap first. Add IPX4 splash resistance and a charging case that pushes total playtime to 24 hours (8 hours in the buds, 16 more in the case), and you have something you can wear through a commute, a workout, a flight or a full workday without babysitting the battery.
Controls are touch and voice based, with customizable taps and quick access to Siri or Google Assistant, plus a Transparent Hearing mode when you want the outside world back in without pulling a bud out. The two-year manufacturer warranty is a reasonable safety net.
Who should buy it: commuters, students, office workers, gym-goers and anyone whose priority is music and calls on the move. It's also my pick for people who've given up on earbuds because nothing fits — the four-size adapter set is the whole point here.
Who should skip it: anyone who needs a boom microphone for competitive team chat, wants a headband rather than something inserted in the ear, or wants spatial audio processing tied to a console. For those jobs, earbuds simply aren't the right tool.
The Void v2 MAX is the opposite philosophy: it's a dedicated gaming headset that happens to be wireless, and it's built to stay on your head for a very long time. The headline feature is simultaneous 2.4GHz wireless and Bluetooth. You can run low-latency 2.4GHz audio to your console or PC for the game itself while Bluetooth handles a phone call or a music app at the same time — or you can just switch between them. That's an underrated convenience if you've ever had to choose between hearing your game and hearing your phone.
Audio hardware is a step up in scale too: custom-tuned 50mm drivers, 32 ohm impedance and 116 dB sensitivity. Big dynamic drivers in a sealed over-ear cup generally mean more physical impact and a wider sense of space than any earbud can produce, and Dolby Atmos Spatial Audio adds directional processing so footsteps and explosions sit in specific places around you rather than in a flat stereo line. For shooters and anything where you're listening for cues, that's the real argument for a headset like this.
The practical side is equally game-focused. Battery life is rated up to 70 hours over 2.4GHz with RGB off, and a 15-minute top-up gets you roughly 6 more hours — that's the kind of number that means you charge it on a weekend, not every night. The omni-directional microphone uses NVIDIA Broadcast technology to cut background noise, though that specific feature needs a compatible NVIDIA GeForce RTX graphics card. On-ear game/chat balance controls let you mix team comms against in-game audio without alt-tabbing, and iCUE software handles sound tuning and RGB customization. Connectivity covers Xbox Series X|S, Xbox One, PC, PS5, PS4, Switch 2 and mobile, with Bluetooth 5.3 and a 30-foot wireless range. Two-year manufacturer warranty applies.
Who should buy it: console and PC gamers who play with friends, want one headset that works across several platforms, and value long battery life and a real microphone over portability.
Who should skip it: anyone who mostly listens to music on the go, wants something that folds into a pocket, or needs a wired connection — there's no headphone jack here.
• Best for small ears and secure fit → Sennheiser CX Plus In-Ear. Four ear adapter sizes and a lightweight in-ear shape are purpose-built for narrow canals.
• Best for gaming audio and positional cues → Corsair Void v2. 50mm drivers plus Dolby Atmos Spatial Audio are made for locating enemies and feeling explosions.
• Best for battery life → Corsair Void v2. Up to 70 hours over 2.4GHz with RGB off versus up to 24 hours total on the Sennheiser.
• Best for voice chat and team comms → Corsair Void v2. A dedicated noise-reducing boom mic with on-ear game/chat balance beats earbud mics for clarity.
• Best for commuting, travel and workouts → Sennheiser CX Plus In-Ear. ANC, Transparent Hearing, IPX4 splash resistance and a charging case are exactly what portable listening needs.
• Best for blocking out an office or a plane → Sennheiser CX Plus In-Ear. In-ear ANC with a good seal is the more effective tool for that specific job.
• Best for one headset across Xbox, PC, PS5 and Switch → Corsair Void v2. Simultaneous 2.4GHz plus Bluetooth 5.3 covers consoles, PC and mobile in one device.
• Best if you hate charging things → Corsair Void v2, again on raw endurance — 70 hours is measured in weeks of casual play.
If you're shopping for a kid or a smaller-framed player, note the honest limitation here: both of these are adult-oriented products. There's no kids' model in this comparison, and if you're specifically after extra bass kids headphones for small ears, or wireless clip on earbuds for small ears, neither of these is that product — though the CX Plus's four-size adapter set is the closest thing to a small-ear solution of the two. If what you actually want is the best gaming headset for small ears, the honest answer is that the Corsair's over-ear memory foam cushions are more forgiving on head size than its bulk suggests, but it's still a full-size headset.
If I had to buy one, I'd buy the Sennheiser CX Plus In-Ear — and the deciding factor is fit for small ears. Four ear adapter sizes, a lightweight in-ear shell and ANC that only works properly once you get a seal make it the more adaptable of the two for people who usually can't wear earbuds comfortably. It also does the most jobs in the most places: commute, desk, gym, flight. That said, if your evenings belong to Xbox or PC and you talk to friends while you play, I'd point you to the Corsair Void v2 instead, because a boom mic, 50mm drivers, spatial audio and 70 hours of battery solve problems earbuds can't touch. Before deciding, check the current price on Amazon for both — the value call is yours to make, not something a spec sheet can settle.
In my opinion, yes — it's the stronger of these two for small ears because it ships with ear adapters in four sizes and uses a lightweight in-ear design. A proper seal is also what makes its Active Noise Cancellation effective, so getting the right tip size genuinely improves both comfort and sound.
Yes. It supports Bluetooth 5.3 alongside 2.4GHz wireless, and you can listen to both at once, so music and calls work fine. Just remember it's an over-ear headset with no headphone jack, so it's not the portable option.
The Corsair Void v2 by a wide margin — up to 70 hours over 2.4GHz with RGB off, plus a 15-minute charge that adds about 6 hours. The Sennheiser delivers up to 24 hours total, split between 8 hours in the buds and 16 in the charging case.
For competitive and immersive gaming, I'd go with the Corsair. Dolby Atmos Spatial Audio, 50mm drivers and on-ear game/chat balance are built for that. The Sennheiser is the better choice for everything outside the game.
