Do you often find yourself fumbling through pockets or bags to locate your earbuds when rushing to catch the subway? This fragmented carrying experience is precisely the motivation behind HUAWEI’s WATCH Buds series.
On April 20, 2026, HUAWEI officially launched the WATCH Buds 2, deeply integrating a smartwatch with true wireless earbuds. This single device meets triple demands for communication, health, and audio. The iterative product represents comprehensive optimization rather than simple hardware stacking. How does it perform? We conducted a week-long in-depth test.
Design: Lighter and Thinner, Premium Feel Elevated
The first impression of WATCH Buds 2 is “lightweight.” The entire device weighs approximately 54.5 grams, 12 grams lighter than its predecessor, with thickness controlled at 14.69mm. Extended wearing no longer causes noticeable heaviness.
The body adopts aerospace-grade titanium alloy combined with ultra-hard nano-coating technology, achieving 200% improvement in wear resistance. This material combination ensures both lightweight portability and durability.
The earbud design is equally compact. Each earbud weighs approximately 4 grams, with volume reduced by 50% compared to traditional TWS earbuds. The octagonal cylindrical shape conforms to ear canal contours. During testing, three hours of continuous wearing caused no discomfort.
The watch body and earbud charging case feature a 360° magnetic adsorption design. When returned, they automatically align and dock precisely. This satisfying “click” magnetic placement eliminates the frustration of repeatedly adjusting angles.
The screen upgrades to a 1.5-inch LTPO flexible display with 36% narrower bezels and 11.6% improved screen-to-body ratio. The 3000-nit peak brightness ensures clear visibility even under bright outdoor light.
The WATCH Buds 2 offers three color options: Obsidian Black, Amber Brown, and Titanium Silver. The Obsidian Black and Amber Brown versions are priced at 3,488 yuan, while the Titanium Silver version with titanium strap costs 3,988 yuan.
Audio: Quality Sound from a Compact Body
Don’t underestimate the audio quality despite the compact earbud size. The WATCH Buds 2 features a full-range micro-planar driver unit combined with triple sound optimization technology, dynamically compensating for sound differences caused by varying ear canal shapes.
Call quality is a highlight of this product. Using bone conduction sensors with DNN deep neural network noise reduction algorithms, callers can hear your voice clearly even in noisy subway cars or busy street environments. Testing confirmed significant environmental noise filtering with high voice fidelity.
The earbuds support hybrid active noise cancellation with two modes: noise cancellation and transparency. Activate transparency mode during commuting to hear both music and surroundings; switch to noise cancellation in the office for focused work.
Touch controls receive a major upgrade. The expanded touch area covers the auricle and cheek, with double-tap for play/pause and triple-tap to switch noise cancellation modes—discreet and efficient, avoiding the awkwardness of pulling out a phone.
The unique left-right adaptive recognition makes usage more casual. No need to distinguish left from right; pick up and wear, and the system automatically calibrates channel allocation. Both single or dual earbud use works seamlessly.
The wrist-controlled earbuds feature is particularly practical. Directly control earbud playback status, volume, and noise cancellation modes through the watch dial. Check remaining earbud battery with a raised wrist—no need to remove the earbuds.
Health: From Recording to Proactive Management
The WATCH Buds 2 runs HarmonyOS 6, with health monitoring capabilities rivaling professional smartwatches.
The health summary feature integrates exercise, heart rate, blood oxygen, sleep, and mood data for comprehensive analysis, automatically generating personalized health reports and improvement suggestions. This one-stop service eliminates the hassle of switching between different functions.
Heart health monitoring supports pulse wave atrial fibrillation and premature beat detection. Users can participate in the HUAWEI heart health research program, with the system continuously tracking cardiac rhythm changes and alerting abnormalities. This feature proves particularly valuable for those with high-stress work schedules.
Sleep monitoring adds sleep apnea screening. The system automatically analyzes deep sleep and light sleep stages while identifying sleep apnea risks, providing targeted improvement plans. After one week of continuous wearing, testers reported significantly detailed sleep reports.
Blood glucose risk assessment represents a key upgrade. After wearing for three or more days, the system analyzes blood glucose trends based on physiological data, providing early risk warnings. It’s important to note this function serves as consumer-grade reference and cannot replace professional medical testing.
Mood monitoring analyzes user stress and fatigue states in real-time, guiding breathing exercises to relieve tension. Combined with 90+ exercise modes, AI automatically interprets exercise data, covering running, swimming, and fitness comprehensively.
SmartFeatures:Empowered by HarmonyOS Ecosystem
Detaching the earbuds, the WATCH Buds 2 itself functions as a fully capable smartwatch.
Digital car key features enable automatic vehicle unlocking when approaching, supporting mainstream vehicle brands. NFC tap-to-pay covers supermarkets, convenience stores, and other scenarios—complete payments with a raised wrist.
Multi-device collaboration breaks boundaries between phones, tablets, and computers. Audio playback and message notifications seamlessly switch across devices, enhancing cross-device collaboration in office scenarios.
Regarding system compatibility, this product perfectly adapts to HarmonyOS, iOS, and Android systems, ensuring both Apple and Android users can purchase with confidence.
Battery performance proves satisfying. The watch delivers up to 3 days of comprehensive battery life, with earbuds lasting 3 hours in noise cancellation mode or 4 hours with it disabled. Combined with watch charging functionality, all-day usage is essentially covered.
Comparison with First Generation: Four Core Upgrades
| Upgrade Dimension | First Generation | WATCH Buds 2 |
| Weight and Material | Heavier, noticeable plastic feel | 54.5g, titanium alloy |
| Audio Performance | Basic driver unit | Full-range micro-planar + bone conduction noise cancellation |
| Health Features | Basic heart rate and sleep monitoring | New blood glucose risk and mood monitoring |
| Interaction Experience | Traditional touch controls | 360° magnetic adsorption + expanded auricle touch |
Target Users and Purchase Recommendations
The WATCH Buds 2 isn’t for everyone. Users in the following scenarios should prioritize consideration:
Commuters and frequent travelers represent the primary target users. The dual-function design significantly reduces burden—one device handles subway calls and café emails. Office professionals benefit from discreet call features, answering meetings with gentle auricle taps and wrist control to avoid frequent phone reaching. Health-conscious individuals gain comprehensive health monitoring data for proactive body management. Tech enthusiasts experience the innovation of the dual-function form factor.
However, audiophiles seeking ultimate sound quality may be disappointed—limited by earbud volume, sound quality cannot match high-end professional TWS products. Users with slender wrists should also try before buying, as the 47mm case diameter may appear too large.
Conclusion
The HUAWEI WATCH Buds 2 represents a new approach in smart wearables—not feature stacking, but scenario deep cultivation. It precisely addresses the user pain point of “too many devices, cumbersome carrying” through innovative form factor design that maximizes value from a single device.
Lightweight design solves wearing comfort issues. Dual online audio and health capabilities ensure practical value. HarmonyOS ecosystem support enables smoother multi-scenario usage. If you frequently travel for business, pursue efficient office work, and dislike device fragmentation, this product deserves a place in your shopping cart. Available across all channels from April 25, with purchases before May 31 receiving one year of HUAWEI Care+ service.
