Huawei FreeBuds 4i Test | CHIP

This is how CHIP tests true wireless in-ear headphones

The different models of true wireless in-ear headphones are tested in the CHIP test center. They have to convince in the categories of sound quality, mobility as well as comfort and equipment.

The Klang naturally makes up the largest part of the overall grade, namely 40 percent. In the test, we stream music in maximum quality via Spotify, while the headphones are connected to a smartphone via Bluetooth. This is a practical test scenario in which we evaluate exclusively subjectively. Two testers rate the clarity and naturalness of the sound, the bass character and the voice representation. There are extra points for active noise cancellation (ANC).

The category carries 30 percent mobility contributes to the overall rating. Here the CHIP testers check the battery life of the headphones and the total runtime including the battery case as well as the charging time and Bluetooth range. It is also relevant whether the case can be charged wirelessly.

To the category Comfort and equipment30 percent of the total score also includes features such as automatic switching on and off, noise canceling, the available control functions and wireless standards. On the other hand, the CHIP editors subjectively rate the firm and comfortable fit of the headphones in a practical test.
