The wireless headphones Huawei FreeBuds 4 allow unrestricted movement, which increases the comfort of using the headphones. This feature is particularly popular with headphones for casual use. However, a certain limiting factor of wireless headphones compared to wired ones is a certain delay in sound transmission between the source and the headphones (but almost indistinguishable for the average user) and the need for regular charging. Unlike wired headphones, wireless headphones are charged separately. The technology used for the sound transmission used by the headphones is Bluetooth 5.2.
The headphones are designed as in-ear headphones, which are inserted inside the ear to provide more or less isolation from ambient noise. The level of isolation may vary depending on whether the ambient noise isolation feature is present or not. One of the main advantages of these headphones compared to over-the-head ones is their stackability and easy portability.

The sound quality can be affected by many factors. When it comes to frequency range, a wider range will allow more detail to be heard during your listening session. However, it is important to note that the ability to perceive frequencies varies from person to person. The average person is able to hear frequencies in the range of 16 to 20 000 Hz. That is why headphone manufacturers usually focus on the 20 to 20 000 Hz range. If the lower values are lower, headphones are better able to reproduce bass tones, as these represent frequencies up to approximately 256 Hz. Conversely, values from 2 048 Hz upwards are treble. Thus, headphones with a high upper limit will provide a much more accurate reproduction of high tones. Headphones Huawei FreeBuds 4 have a frequency range of 20 - 20000 Hz.
The headphones are composed of many various components, one of the most important is the diaphragm. Diaphragm transforms the electrical signal into sound and therefore its quality affects the overall listening experience. There are three types of diaphragms: thin, medium-thick, and thicker. A thin 6 mm thick diaphragm responds quickly to high frequencies but less sensitively to bass. The medium-thick 10 mm diaphragm provides a balanced sound profile, allowing you to enjoy both bass and treble. The thicker 20 mm diaphragm is more sensitive to higher frequencies but has a poorer bass response. These headphones are equipped with the 14.3 mm.
Active Noise Cancellation provides an even quieter listening experience.

These headphones have a battery capacity of 30 mAh. In terms of headphone battery life as a significant factor in the purchase decision, it depends on what you want to use the headphones for and potentially how often you will be able to recharge them. Headphones with up to a few hours of battery life are more suitable for home use as they will require more frequent charging. Headphones with a battery life of around 10 hours or more are already more suitable for commuting and shorter journeys. However, nowadays you can also find headphones on the market that have a battery life in the higher tens to hundreds of hours. In this case, you do not have to worry about your headphones simply running out of power on longer journeys, and you will not have to deal with constant recharging. The battery life of the Huawei FreeBuds 4 reaches up to 4 hour(s).
Charging time is 1 hour(s).
