In general, Huawei FreeBuds 4 they do meet the value for money formula with active noise cancellation, touch sliders and Bluetooth 5.2. The case design is nice, simple and comfortable to carry in your pockets. Glossy plastic can make it a bit slippery and this gray detail blew me away, but it’s just a cosmetic issue.
The design of the headphones makes them comfortable and safe, despite the lack of a silicone nipple. Personally I find the length of the headset somewhat annoying, since it comes out a lot and if you are one of those who wear bicycle helmets or wear something else on your head, you will have some discomfort.
At least, the weight of the headphones is 4.1 grams and hardly feels, and they feature an IPX4 splash protocol. Sensitivity is also just right by having commands like tap, hold, and swipe, giving you control over playback, noise cancellation, and volume. Unfortunately, you can only customize the double tap feature on each earbud.

Regarding noise cancellation, it meets expectations and is capable of blocking out a fair amount of ambient noise. Even with those, keep in mind that it does not bring a pacifier and the insulation will depend on how well the headset fits. Those of Huawei explain that the headphones are capable of canceling up to 25 dB and the system applies one of 16 different ANC modes. This sounds great, but it still doesn’t isolate the ear from noise for a better experience.
The performance of FreeBuds 4 must be evaluated with the AI life, the application that allows you to make adjustments to the headphones. From there you can activate or deactivate the ANC and HD calls, manage the dual connection if you have other pairs of headphones, modify the gestures, search for the headphones, activate or deactivate the position detection and update the system.

What is needed is an equalizer, so you will not be able to customize the performance of the headphones. The factory settings, likewise, do a good job for the treble and bass, even though the support is generic. Broadly speaking, the sound is good and balanced, whether for listening to music or receiving calls. By the way, HD calls are not that they suppose a quality jump. Yes you hear something better, but nothing more.
To finish, autonomy does have some drawbacks. Huawei says the earbuds can last for four hours of playtime and a total of 22 hours with the charging case. If you use noise cancellation, the autonomy drops to 2.5 and 14 hours, respectively. At least, the charging case has good speed for the headphones: in about 15 minutes you can have them half charged without problems.
