The Huawei Freebuds Pro 4 use an in-ear fit and are fully true wireless, with no cables or neckband involved. Each earbud weighs 11.6 grams and comes with stereo speaker support, while wingtips are not included. The design carries an IP54 ingress protection rating, making the earbuds resistant to sweat — a practical consideration for on-the-go use. There is no RGB lighting, UV light, or display present on either the earbuds or the case, keeping the overall form factor straightforward and understated.
The Freebuds Pro 4 feature both active noise cancellation (ANC) and passive noise reduction, providing two distinct layers of sound isolation during use. Audio is handled by an 11 mm driver unit capable of reproducing a wide frequency range spanning from 14 Hz up to 48,000 Hz. Spatial audio is supported, adding a dimensional quality to compatible content, though Dolby Atmos and Dirac Virtuo are not present. The driver does not use a neodymium magnet.
Each earbud houses a 55 mAh rechargeable battery delivering up to 7 hours of playback, and that figure remains the same when ANC is active. The charging case holds a 510 mAh cell, bringing the combined total battery life to 26 hours. A full charge takes 1.5 hours, and the case supports wireless charging, removing the need for a cable in day-to-day use. A battery level indicator is included so users can keep track of remaining power at a glance. Solar charging is not available on this model.
The Freebuds Pro 4 connect wirelessly via Bluetooth 5.2 with a maximum range of 10 meters, and the charging case uses USB Type-C for wired power input. In terms of audio codecs, LDAC and AAC are both supported, while the aptX family of codecs — including aptX, aptX HD, aptX Adaptive, aptX Low Latency, aptX Lossless, and aptX Voice — are not available. Bluetooth LE Audio and Auracast are likewise absent, and pairing options do not include NFC or fast pairing functionality.
The Freebuds Pro 4 include a solid set of everyday features, starting with ambient sound mode, in-ear detection for automatic playback pause, and a find device function for locating misplaced earbuds. They support multipoint connection across two devices simultaneously and can be used as a headset with a mute function available during calls. Controls are handled through a panel placed on the device itself rather than an in-line control panel on a cable. Fast charging is supported, and voice prompts are present to guide users through settings and status changes. A travel bag is included in the box, and the product is backed by a 2-year warranty. Notification readout, a body temperature sensor, and a built-in camera remote are not part of the feature set.
The Freebuds Pro 4 are equipped with an array of 8 microphones, and noise cancellation is applied to the microphone input to help reduce unwanted background sound during calls and voice interactions.
