How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want flagship-style sound with adaptive noise cancellation and a long battery, choose ONEPLUS Buds 4; if you need featherweight, near-invisible earbuds built for small ears and all-day comfort, choose VISOUND Air Skin Tones.
• ONEPLUS Buds 4 — biggest strength: a serious audio and noise-cancelling package, with dual drivers, dual DACs, up to 55dB adaptive ANC and up to 45 hours of battery.
• ONEPLUS Buds 4 — biggest trade-off: it's a full-size, feature-dense earbud in a bold Green finish, not a discreet or minimal one, and its best extras lean on the OnePlus ecosystem.
• VISOUND Air Skin Tones — biggest strength: a 3g-per-bud, stemless, skin-matching design that disappears in your ear and comes in 7 shades, including Light Bisque.
• VISOUND Air Skin Tones — biggest trade-off: it prioritizes comfort and discretion over raw audio hardware and active noise cancellation, with 24 hours total battery and IPX5 water resistance.
• Who each pick is for: the ONEPLUS Buds 4 suits Android and OnePlus users who want maximum sound and quiet; the VISOUND Air Skin Tones suit small-eared, comfort-first users who want their earbuds to go unnoticed.
The ONEPLUS Buds 4 is the earbud you pick when sound quality and noise control sit at the top of your list. The spec sheet reads like a flagship: dual DACs paired with dual drivers, Hi-Res LHDC 5.0 support for near-lossless playback, OnePlus 3D Audio, and a 20Hz–40,000Hz frequency range that reaches well past what most people can hear. In my opinion, that combination is aimed squarely at listeners who care about detail in the highs and weight in the bass, not just a background soundtrack.
The headline feature is the noise cancellation. OnePlus rates it at up to 55dB of adaptive ANC, and describes it as significantly upgraded from the Buds 3, with a real-time Adaptive Mode that shifts between cancellation and transparency automatically. Add a 3-mic system with an AI Clear Call algorithm, and this is a set built for noisy commutes, open-plan offices and crowded streets. Battery is rated at up to 45 hours, and the touch controls cover active noise cancellation plus voice-assistant wake with a tap.
VISOUND Air Skin Tones: Who It's For
The VISOUND Air Skin Tones solves a different problem entirely: earbuds that stay comfortable and stay hidden. At just 3g per earbud, VISOUND claims they're 43% lighter than standard earbuds, which is the kind of number that matters if you've ever pulled out a normal pair after two hours and felt relief. The stemless flat geometry is designed to adapt to any ear shape, and VISOUND explicitly targets small or sensitive ears, shipping with two ear tip sizes so you can get a secure, pressure-free fit that won't slip.
The skin-matching angle is the real differentiator. It's available in 7 shades — Deep Espresso, Warm Cocoa, Copper Amber, Golden Toffee, Soft Sand, Bare Peach and Light Bisque — so the bud blends with your skin tone instead of announcing itself. For anyone who dislikes the look of a stem hanging out of their ear, that's a meaningful design choice, and it's paired with IPX5 water resistance for sweat and splashes.
On the tech side, it runs Bluetooth 5.4 with one-tap pairing, auto-reconnect and multi-device switching, plus a 50ms latency figure that VISOUND positions for calls, video and gaming. Battery is 6 hours per charge plus 18 from the USB-C case, for 24 hours total, and the case has a digital LED display. Noise control here is Environmental Noise Cancellation rather than active ANC — it helps with calls, but it is not the same tool as the Buds 4's adaptive system.
Buy it if comfort, weight and discretion are your priorities, or if standard earbuds simply don't fit your ears. Skip it if you want maximum bass depth, active noise cancellation, or the longest possible battery between charges.
• Best for noise cancellation → ONEPLUS Buds 4. Up to 55dB adaptive ANC versus environmental noise cancellation on the VISOUND.

If I had to buy one, I'd take the ONEPLUS Buds 4. In my opinion it's the more complete product: real adaptive noise cancellation, a far stronger audio architecture, and up to 45 hours of battery make it the better everyday companion for commuting, calls and music. The VISOUND Air Skin Tones is genuinely clever at what it does — 3g buds in seven skin tones is a niche almost nobody else serves — but that's a comfort-and-discretion purchase, not a sound-and-silence one. If your ears are small or you want your earbuds invisible, flip the decision without hesitation. Otherwise, go ONEPLUS.
Yes, on the specs. The Buds 4 uses adaptive active noise cancellation rated up to 55dB with an Adaptive Mode; the VISOUND uses environmental noise cancellation, which is a lighter approach aimed mainly at call clarity rather than blocking out a train carriage.
That's exactly who they're designed for. At 3g per bud with stemless flat geometry and two included ear tip sizes, they're built for small or sensitive ears and a pressure-free fit that won't slip.
The ONEPLUS Buds 4, by a wide margin — up to 45 hours versus 24 hours total on the VISOUND (6 hours per charge plus 18 from the case). If you hate charging, that gap matters.
The VISOUND Air Skin Tones is the simpler pick, since it pairs over standard Bluetooth 5.4 with iOS, Android and other devices. The Buds 4 still works as a Bluetooth headset, but its extras like AI Translation and Steady Connect are tuned for the OnePlus ecosystem. Either way, check the current price on Amazon before deciding.
