Those who want to isolate themselves from the environment with their headphones and enjoy music intensively are less well served with the Freebuds 4. The Huawei headphones have other qualities: they sit incredibly comfortably, sound well-balanced and support simultaneous connection with multiple devices including automatic switching...
The Freebuds 4 shone with the best sound in this comparison. Here, Huawei focuses less on rich detail and more on undistorted voices and warm tuning. The earplugs do not seal the ears. This makes them comfortable to wear, but the noise-cancelling is weak. The operation by touch and tip is pleasing, and the good app is a practical addition. However, the battery life is a little short.
If in-ears in the ear canal bother you, the FreeBuds 4 are an open-fit alternative with decent ANC. You should not expect sound miracles.
