Product Overview

Huawei FreeBuds 4 are premium true wireless headphones introduced in 2021. Compared to their predecessor, the FreeBuds 3, these earbuds are smaller and lighter; the new Open-fit Active Noise Cancellation 2.0 delivers strong ANC performance while keeping the wearer aware of important environmental sounds.
The FreeBuds 4 use Huawei's adaptive ear-matching technology to detect the wearer's unique ear shape and intelligently adapts the noise cancellation modes to improve the listening experience. Their new 14.3mm LCP dynamic drivers drivers extend the frequency range in both the top and low ends.
On the battery life front, the FreeBuds 4 extend the performance of the FreeBuds 3 and are able to deliver up to 22 hours of playback (ANC off). With fast charging, 2.5 hours of playback time can be added in 15 minutes.
Huawei also markets the FreeBuds 4i, which make for a more affordable option.

Reviewers from androidauthority have found the following***:
The FreeBuds 4 are rated for four hours of battery life with noise-cancelling turned off. Turning ANC on will reduce battery life to just 2.5 hours. The battery inside the case brings another 22 hours (ANC off) to the table. There is also a version of the FreeBud 4 that comes with a case that can be charged wirelessly.

Reviewers from t3 have found the following***:
Huawei Freebuds 4 have a one-size-fits-all approach. They are very light and comfortable in the ear, if that's the style of bud you prefer. To manage your music each bud has touch controls, you swipe up or down the stem to adjust the volume. You tap twice to pause or play the track and hold down to switch noise cancelling on or off. Each bud has a built-in microphone, calls were overall clear and loud.
