It seems like you're looking for information about any potential issues or criticisms regarding the Huawei FreeBuds 4. Here are some points that have been highlighted in reviews:

Noise Cancellation: The active noise cancellation (ANC) is not as effective as some competitors, and ambient noise can still be heard.

Sound Quality: While the sound quality is decent, the bass could be deeper, and the earbuds don't get loud enough for some users.

Fit: The open-fit design might not provide a secure fit for everyone, which can be a concern during vigorous activities.

Battery Life: The battery life is shorter compared to some other models, especially when using ANC.

These points might be considered "deceptions" if you were expecting top-tier performance in these areas. However, the FreeBuds 4 do offer a comfortable design and useful features like touch controls and multi-device connectivity
