The Huawei FreeLace is Bluetooth 5.0 in-ear headphones which are connected by a flexible cable passing behind the neck. They have two small tubes that contain the battery and the headphones magnetize when they are not in the ears. The peculiarity of the Huawei FreeLace is that they do not need a cable to be recharged. You can detach the right earpiece to reveal a male USB-C plug that you plug into the USB-C port of an Android smartphone.
It’s as weird as plugging a 1st gen Apple Pencil into an iPad’s Lightning port, but that makes for a device that we know charging won’t be a problem unless the smartphone runs out of juice, but in this case the headphones will be useless anyway.
In Search of the best Earphone
In order for the bought gadget to fulfill all requirements, it is necessary to choose the appropriate headphones based on certain criteria and pay attention to certain essential features. Indeed, the configuration, size, look, and function of this device for listening to music are all distinct from one another. Sound quality and loudness, noise isolation, sensitivity, power, and a design that is compatible with the anatomy of the ear are among the most important considerations when purchasing headphones. Aside from that, consumers are concerned with how heavy the gadget is and whether or not it has any extra features (such as a built-in microphone). The most essential elements are always stated on the package by the manufacturer; all that is left is for the consumer to learn how to interpret them.

The autonomy announced by Huawei is 18 hours, well above the BeatsX and Bullets Wireless (8 hours each). Five minutes of charging is enough to have four hours of battery life. The Huawei FreeLace will soon be on sale for 99 $ in four colors.
What Is Active Noise Reduction Technology?
The reduction of active noise is a wholly technology permits to reduce the surrounding noise. It should be distinguished from so-called “passive “noise reduction which simply consists of isolating your ears from the outside world by completely enveloping them.
There, this technology will have the merit of isolating you from external noise such as the blast of an aircraft engine or noise in public transport. Without it, the user would have to increase the volume sharply to hear properly, at the risk of damaging your ears after several minutes of listening.
How Does Active Noise Reduction Work?
This active noise reduction technology records outside noise and returns an opposing signal to cancel ambient noise. In terms of sound, 2 opposing signals cancel each other out. We have tested this technology several times. It is impressive by reducing 80% of the surrounding noise on the most efficient models. It is especially effective with low frequencies and less in the treble. In summary, users who travel a lot in public transport will appreciate this active noise reduction technology more.
What Are The Sound Characteristics Of The Headphones?
The sensitivity communicates a value of the sound level, between 89 and 107 decibels. More precisely, it expresses the audio power that the headphones need for 1 watt of power. For a power of 3 additional decibels, the power in watts will double. The higher the decibel value, the higher the volume of the device will be. The volume should be kept limited so as not to damage the ears.
Distortion affects unwanted changes in a signal. This is a value that reflects the difference between the input and output signal. In a majority of cases, this value drops below 1%, closer to 0, for sound reproduction faithful to reality. You will see clear differences between a value of 0.02% and 0.8%. The frequency is expressed in hertz as 2 distinct values (5-20,000 hertz). They reflect the ability of a signal to go low in the bass and go up high in the treble. It restores a sound as faithful as possible to reality.
