The HUAWEI FreeBuds Pro 4 enter the market as a premium pair of wireless earbuds designed for high-resolution sound, intelligent noise control, and long-lasting comfort. With a refreshed design, dual-driver audio system, improved ANC, and stronger battery efficiency, these earbuds aim to deliver a flagship listening experience for music lovers, travelers, commuters, and professionals who depend on clear sound during calls and daily use. This article explores everything you need to know, from design and comfort to sound performance, battery life, controls, connectivity, and durability.
Design and Build Quality
The HUAWEI FreeBuds Pro 4 come in three colors: Black, White, and Green. Each earbud weighs approximately 5.8 grams, making them extremely light and comfortable for long listening sessions. The earbuds measure 29.1 mm in height, 21.8 mm in width, and 23.7 mm in depth — a compact size tailored for ergonomic fit. The charging case is equally refined, measuring 46.9 mm × 65.9 mm × 24.5 mm and weighing around 47 grams. Its pocket-friendly profile ensures convenience for travel and everyday carry.
The build quality reflects Huawei’s attention to detail. The earbuds are rated IP54, offering resistance to dust and splashes, although the charging case is not waterproof. The overall structure is durable, sleek, and premium, giving users a sense of quality that matches the price point.
Audio Performance and Speaker Technology
Huawei integrates a powerful dual-driver system featuring an 11 mm dynamic driver and a planar diaphragm driver. This high-end setup allows the FreeBuds Pro 4 to deliver rich bass, crisp vocals, and detailed high frequencies. Whether listening to music, watching videos, or gaming, users can expect a balanced sound signature with improved clarity and separation.
The earbuds also include Digital Cross-Over technology, Triple Adaptive EQ, and advanced Active Noise Cancellation (ANC). The ANC performance is strengthened by the combination of microphones and internal tuning algorithms, allowing the earbuds to intelligently detect noise levels and adjust in real time. Transparency Mode lets users hear their surroundings without removing the earbuds, making them ideal for public transportation, offices, and outdoor activities.
Battery Life and Charging Performance
Battery life is one of the highlights of the FreeBuds Pro 4. Each earbud houses a 55 mAh battery, while the charging case includes a 510 mAh battery. Wired and wireless charging are both supported: the USB-C port accepts 5V-0.5A input or above, while wireless charging works up to 5W.
Charging takes approximately 40 minutes for the earbuds when placed inside the case. The charging case takes around 1 hour to charge via cable and about 150 minutes via wireless charging.
Battery performance varies based on ANC and codec mode:
With High-Resolution L2HC/LDAC Enabled
- 6.5 hours music playback (ANC off)
- 4.5 hours music playback (ANC on)
- Up to 31 hours total with case
With AAC Codec Prioritizing Connection
- 7 hours music playback (ANC off)
- 5 hours music playback (ANC on)
- Up to 33 hours total with case
Call Time
- 4.5 hours (ANC off)
- 3.5 hours (ANC on)
These numbers ensure all-day listening, making the earbuds suitable for travel, work, and extended entertainment.
Smart Controls and User Interaction
The FreeBuds Pro 4 offer intuitive touch and press controls:
- Two taps: Answer/end call, play/pause, next/previous track, wake voice assistant
- Three taps: Change songs
- Slide: Adjust volume
- Press and hold: Toggle noise cancellation, reject calls, activate voice assistant
These tactile gestures allow users to manage audio and calls quickly without reaching for their smartphone.
Connectivity and Compatibility
With Bluetooth 5.2, the earbuds maintain stable connections and low latency performance. They support Dual Device Connection, allowing users to switch between devices such as a laptop and smartphone without manually reconnecting.
Huawei devices running EMUI 10 or later benefit from a convenient pop-up pairing interface for faster setup. This seamless integration matches the experience typically associated with high-end ecosystems like Apple and Samsung.
Advanced Sensors and Smart Features
The HUAWEI FreeBuds Pro 4 include several sensors designed to improve accuracy and user experience:
- Infrared sensor
- Hall sensor
- Gyroscope
- Accelerometer
- Bone acoustic sensor
- Touch sensor
- Press sensor
These components enable intelligent ear detection, enhanced call clarity, and responsive controls. The bone conduction sensor improves voice call quality by separating speech from background noise, which is particularly useful in busy environments.
Durability and Water Resistance
The IP54 rating ensures protection against dust and splashes for the earbuds. Although not designed for swimming or heavy rain, they can handle sweat and light moisture during workouts or outdoor walks. Users should avoid exposing the charging case to water, as it has no waterproof rating.
