Key Features
49dB Smart Adaptive Noise Cancellation
This is the headline feature, and it’s genuinely impressive at this price point. The 49dB maximum noise reduction puts the Buds 3 in the same league as premium ANC earbuds that cost significantly more.
But what makes it “smart” and “adaptive”? The earbuds use multiple microphones to detect ambient noise levels and automatically adjust the ANC intensity based on your surroundings. In a quiet room, the ANC will be less aggressive to save battery. On a noisy train or plane, it will ramp up to maximum to block out engine drone and chatter.
In real-world use, the ANC effectively reduces low-frequency noise like air conditioning hum, engine noise, and traffic rumble. It’s less effective at blocking sharp, high-frequency sounds like crying babies or keyboard clicks—but that’s true of even the most expensive ANC earbuds.
Hi-Res Audio with LHDC 5.0
The OnePlus Buds 3 carries the Hi-Res Audio Wireless certification (the famous “小金标”), which is rare at this price point. This is made possible by support for LHDC 5.0, OnePlus’s high-resolution audio codec that can transmit audio at up to 1Mbps.
What does this mean for you? In simple terms, you get near-lossless audio quality when paired with a compatible device. You’ll hear more detail, better instrument separation, and a wider soundstage. However, note that LHDC 5.0 requires a OnePlus phone (or select other Android devices). Without it, you’ll default to AAC or SBC, which is still good but not quite the same level.
Sliding Volume Control
One of the most user-friendly features on the Buds 3 is the sliding volume control. Instead of tapping repeatedly to adjust volume, you simply slide your finger up or down on the stem of the earbud. It’s intuitive, accurate, and works really well in practice.
This is the kind of thoughtful design that makes daily use more pleasant. You don’t need to pull out your phone every time you want to tweak the volume—just a quick gesture and you’re done.
44-Hour Total Battery Life
Battery life is exceptional. The earbuds alone offer up to 10 hours of playback with ANC off and 6.5 hours with ANC on. With the charging case, that extends to a massive 44 hours without ANC and 28 hours with ANC.
This means you can easily go through a full week of commuting without worrying about charging. Even heavy users will only need to charge once every few days. The case charges via USB-C, though wireless charging isn’t supported.
Fast Charging: 10 Minutes for 7 Hours

Running late and your earbuds are dead? The fast charging feature is a lifesaver. A quick 10-minute charge gives you 7 hours of playback. This is perfect for those mornings when you forget to charge overnight or when you’re rushing to catch a train.
Dual Connection and Google Fast Pair
The Buds 3 supports dual connection, allowing you to connect to two devices simultaneously. This is incredibly convenient—you can listen to music on your tablet while staying connected to your phone for calls. Switch between them seamlessly.
Google Fast Pair makes the initial setup effortless if you’re using an Android device. Just open the case near your phone, and the pairing prompt appears instantly.
IP55 Water and Dust Resistance
With an IP55 rating, the earbuds are protected against sweat and light rain. They’ll handle gym sessions, jogging, and unexpected light showers just fine. However, they’re not designed for swimming or submersion, so keep that in mind.
Design & Build Quality
Appearance
The OnePlus Buds 3 has a sleek, modern aesthetic that’s typical of OnePlus products. Available in Splendid Blue and Metallic Grey, both finishes look premium. The glossy finish on the earbuds and case does attract fingerprints, but it’s nothing a quick wipe won’t fix.
The earbuds feature a stem-style design, similar to AirPods Pro, which sits comfortably and securely in the ear. The charging case is compact and pocket-friendly, with a satisfying magnetic closure.
Materials and Finish
The build quality is solid for the price. The case feels robust, and the earbuds themselves are lightweight. The glossy finish, while attractive, does mean that scratches will be more visible over time. A matte finish might have been more practical, but that’s a matter of personal preference.
Comfort and Fit
At just 4.8 grams per earbud, the Buds 3 are lightweight and comfortable for extended wear. They come with three sizes of silicone ear tips (S, M, L) to help you find the best seal. A good seal is crucial for both comfort and optimal noise cancellation.
Most users find them comfortable for 2-3 hours of continuous use. For longer sessions, you might want to take short breaks to give your ears a rest. The in-ear design provides passive noise isolation, which works together with the ANC for a more immersive experience.
Durability
The IP55 rating ensures the earbuds can handle sweat and minor dust exposure. However, like any electronic device, they should be treated with care. Avoid dropping them frequently, and keep them away from extreme temperatures.
Everyday Performance
Sound Quality
The 10.4mm composite dynamic driver delivers a sound signature that’s well-balanced, with a slight emphasis on bass—typical of consumer-oriented earbuds. The bass is punchy without being overwhelming, the mids are clear and detailed, and the highs are crisp.
With LHDC 5.0 enabled, the sound quality takes a noticeable step up. Tracks have better separation, and you can pick out details that might be lost with standard codecs. The soundstage is wider than expected for in-ear earbuds, making for a more engaging listening experience.
For most listeners, the sound quality will be more than satisfactory. Audiophiles might prefer a more neutral tuning, but the Buds 3 can be adjusted via the OnePlus’s built-in equalizer presets.
Noise Cancellation Performance
The 49dB Smart Adaptive ANC is genuinely impressive. In a busy office, it effectively drowns out keyboard clatter, distant conversations, and HVAC noise. On public transport, it significantly reduces engine noise and background chatter.
The adaptive aspect works well—the transition between ANC levels is smooth and automatic. You don’t need to fiddle with settings; the earbuds handle it for you.
There are also transparency modes that let ambient sound in when you need to hear your surroundings. A few taps in the app or quick gestures let you switch between ANC, transparency, and off modes. This is useful for announcements at airports or when you need to be aware of traffic.
Experience 49dB ANC for yourself!
Call Quality
With multiple microphones and AI noise reduction, call quality is solid. The microphones do a good job of isolating your voice from background noise, even in moderately noisy environments. Callers on the other end report clear audio, though it’s not quite at the level of dedicated business headsets.
The earbuds also support dual connection, so you can seamlessly switch between a work laptop and personal phone during calls.
Touch Controls
The touch controls are responsive and customizable through the OnePlus app. You can set up different gestures for playback control, volume adjustment, and ANC toggling. The sliding volume control is a standout feature—it’s accurate and avoids the frustration of inaccurate taps.
However, some users might find the touch controls a bit sensitive. It takes a little practice to find the right touch pressure to avoid accidental triggers. The OnePlus app allows you to adjust the sensitivity to your preference.
Connectivity and Range
Bluetooth 5.3 provides stable connectivity with excellent range. You can easily leave your phone in one room and move around without dropouts. The connection is reliable even in crowded areas with lots of wireless interference.
Google Fast Pair makes the setup process virtually instant on Android. The earbuds also support automatic connection to previously paired devices, making the whole experience seamless.

Discussion
Compared to the Sony WF-C700N, the OnePlus Buds 3 offers significantly more features. The ANC is more powerful (49dB vs 20dB), battery life is more than double, and the inclusion of LHDC 5.0 provides better audio quality. However, Sony’s audio tuning is more refined, and the WF-C700N has a more compact design.
Against the Nothing Ear (a), the competition is closer. Both offer excellent value with similar ANC levels and battery life. The OnePlus Buds 3 has an advantage with its sliding volume control and slightly better battery life. The Nothing Ear (a) has a distinctive transparent design and a more balanced sound profile. Your choice may come down to brand preference and design aesthetic.
Overall, the OnePlus Buds 3 stands out for its exceptional ANC performance and comprehensive feature set at a competitive price point.

Buying Guide: What to Look for in ANC TWS Earbuds
1. Noise Cancellation Level
Look for the ANC depth (in dB) . Higher numbers (like 49dB) indicate stronger noise cancellation. However, the effectiveness depends on the seal in your ear and the type of noise. Low-frequency sounds are easier to cancel; high-frequency sounds are more challenging.
Pro tip: Try different ear tips to achieve a good seal—it dramatically improves ANC performance.
2. Audio Codecs and Hi-Res Support
Codecs determine the quality of the wireless audio stream. LHDC 5.0, LDAC, and aptX Adaptive offer the highest quality, but they require compatible devices. AAC and SBC are more universal but lower quality. If you’re an audiophile, look for Hi-Res Audio certification.
3. Battery Life
Consider both earbuds-only and total battery life. 10+ hours with ANC off and 30+ hours total is excellent. Fast charging is a game-changer—it should give at least 3 hours of playback from a 10-minute charge.
4. Fit and Comfort
This is crucial. If the earbuds don’t fit well, the sound quality and ANC will suffer. Look for earbuds that come with multiple ear tip sizes. Lightweight earbuds (under 5 grams each) are more comfortable for long sessions.
5. Controls and Usability
Touch controls should be responsive and customizable. Features like sliding volume control or pinch controls are more reliable than tap-based volume adjustment. Dual connection is also a plus for multitaskers.
6. Water Resistance
IPX4 is fine for gym use; IP55 adds dust resistance. Unless you’re swimming, anything above IPX4 is suitable.
7. Brand Ecosystem
If you have a OnePlus phone, the Buds 3 will work better than any other brand. Similarly, Samsung, Apple, and others have ecosystem benefits. Consider your phone brand when choosing earbuds.
