Is the noise suppression safe?
Relaxed and safe - the Huawei FreeBuds 4i in the stress test
How well do Active Noise Cancellation and Awareness Mode work in the hustle and bustle of everyday life?
Listening to music, radio plays or podcasts can mean a liberating switch-off in noisy situations, but can also be distracting in some situations, such as in traffic, so that we no longer concentrate sufficiently on the surroundings. With active noise suppression and awareness mode, the new Huawei FreeBuds 4i manage the balancing act between audio entertainment, feeling good and being safe - with a battery life of up to 10 hours.
Especially if you live in the big city, you can tell a song about it: Noise is everywhere. Regardless of whether it is caused by construction sites, road and air traffic or other sources, something often interferes with the urgently needed music enjoyment, one's own relaxation or concentration. If you are also outside and cannot simply close the windows, blocking out the noise is always difficult and therefore annoying.
The new Huawei FreeBuds 4i address exactly this problem - with Active Noise Cancellation (ANC). But their shape not only shields the ears from unpleasant background noises quite well and thus allows us to go through the day more relaxed. No, they also have an additional function that is particularly useful in road traffic: the awareness mode.
How magic works
A detailed physical treatment is not expected at this point, but we still want to briefly explain the function of ANC and Awareness Mode, because both are quite astonishing. Active noise cancellation does not try to keep the noise as low as possible, on the contrary, it is actually amplified - at least for the time being. How it works: The microphones of the Huawei FreeBuds 4i pick up the ambient noise, a dedicated processor detects volume, pitch and other characteristics in milliseconds, reverses the wave profile of the noise and sends it to the ear in addition. The reverse polarization of the sound waves cancel each other out and the noise is faded out. In music production, this phenomenon is used in a similar way using terms such as "phasing".
In Awareness Mode, the principle is a bit simpler, but no less impressive: the integrated microphone analyzes and recognizes external signals, noises, sounds - in short: the sound of the environment - and, if necessary, highlights them in addition to the music being played so that events can be the surroundings are not covered, but made even more audible.
»Loss mi anglahnt!« By noise suppression
In the big city, the next construction site is usually not far away. Often annoying, but very practical for an active noise cancellation test. That's why our tester sat down next to a construction site with the Huawei FreeBuds 4i and listened to music. Not very intuitive, but everything for science!
And lo and behold! It works! The ANC sometimes reacts with a delay when things are really going on on the construction site and some machine is having a particularly good day, but basically the filtering out of background noises works really well. On public transport, you hear much less of the conversations of the people sitting next to you and even loud children's screams are muffled and faded out - this makes it easy to relax.
Safe and sound in awareness mode
If you prefer to use a bicycle as a means of transport or if you like to walk in areas with heavy traffic, the noise suppression could lead to us not noticing relevant events in the area. Such isolation in a situation in which you are the second strongest participant compared to a motor vehicle could be tricky. With a gentle touch gesture on the new Huawei FreeBuds 4i, you can quickly switch between the modes. A friendly voice explains which mode we are currently in.
In Awareness Mode you can hear if someone buzzes you at the pavement or zebra crossing for all the dancing, or if someone rings the doorbell behind you. This effect also seems to work differently depending on the frequency of the ambient noise, but the mode always fulfills its purpose in any case.
Our conclusion: thumbs up!
The Active Noise Cancellation and Awareness Mode of the new Huawei FreeBuds 4i do exactly what they are supposed to do - and it works really well. At first it might be a somewhat unusual listening experience, but it also makes interesting sound experiments possible and you perceive the surroundings in a completely different way. So you can get through the hustle and bustle of everyday life relaxed and safe. Double thumbs up!
Apart from Active Noise Cancellation and Awareness Mode, what else is there to say about the new Huawei FreeBuds 4i? They are characterized by their compact design and comfortable to wear. They offer crystal clear sound for all types of audio entertainment. And thanks to two microphones, the highest quality calls are guaranteed. But the best thing is: Enjoying music with the new Huawei FreeBuds 4i can last up to 10 hours at a time; Thanks to the innovative fast charging technology, 10 minutes of charging time is sufficient for another 4 hours of audio experience.
From now on, the new Huawei FreeBuds 4i are at participating trading partners available at a price of 79 euros. The Huawei FreeBuds 4i come in the colors Carbon Crystal Black and Ceramic White and will also be available in a striking Honey Red at a later date.
