Anonymous users2024-02-07The three modes of noise cancellation, transparent transmission, and off cannot be turned on at the same time, and the earbuds default noise cancellation status when leaving the factory.
You can press and hold the touch panel of the left earphone to set the noise cancellation mode, and there will be a prompt sound to remind the corresponding status during operation.
Only the left earbud supports the touch function, when your hands are wet or dirty, etc., it will affect the touch accuracy, please dry your hands and clean them before trying.
If you only want to set two of them through the earphone touch, you need to check the "More" in the Bluetooth settings menu of the above or Magic versions or the noise control of the Smart Life app.
Set it up via your Huawei phone.
When the earbuds are connected to a mobile phone or tablet of above or above or Magic or above, go to the mobile phone settings - Bluetooth - paired settings - earphone settings to set the relevant settings.

Anonymous users2024-02-04The noise cancellation of Bluetooth headsets can be divided into 3 types according to the principle.
1.Passive noise cancellation.
This refers to in-ear earbuds, because the earbuds are plugged into the ear through a silicone cover, so it has a better effect of isolating external sounds. And this noise reduction is full-range, that is, it is effective for sound from 20Hz to 20000Hz, and this dynamic noise reduction is lossless sound quality. Basically, the general HIFI earbuds are in-ear for this reason.
2.Call noise cancellation.
Call noise cancellation refers to the design of making a call with a Bluetooth headset so that both parties to the call can hear clearly. Common ones such as Qualcomm's CVC noise reduction. Its principle is to use the chip inside the Bluetooth headset to filter the signal received by the call microphone to reduce the wind noise in the outside world.
At the same time, it can also weaken the echo of the call source transmitted by the other party. CVC noise reduction does not have an additional microphone to collect external noise, so the noise reduction effect still cannot fully meet the actual application. Therefore, some Bluetooth headsets are also designed with an additional microphone to collect ambient noise, and then the internal processor will subtract the external ambient noise collected by the additional microphone from the signal of the call microphone.
Therefore, this noise reduction effect is much better, and this noise reduction is what we often call "uplink noise reduction".
3.Active Noise Cancellation.
Active noise cancellation refers to the regular noise (aircraft engine noise) of the outside world (aircraft engine noise) collected through a noise pickup microphone in some specific occasions, such as high-speed rail aircraft. Through the circuit or algorithm, the reverse noise signal is added to the ** signal, that is to say, the sound heard by the human ear and the external noise are directly canceled, so as to achieve the effect of noise reduction.

Anonymous users2024-02-03How to turn on noise cancellation for Bluetooth headphones:
1. Turn on the switch of the Bluetooth headset. When connecting to Bluetooth headphones, the on/off key can also be used as a pause button.
2. Turn on your phone, enter the main interface, and click the "Settings" button to enter the page.
3. Find the "Bluetooth" option and click to enter the page.
4. At this time, you will find that the Bluetooth is not turned on, just gently flip the switch to turn on the Bluetooth of the mobile phone.
5. After a period of retrieval of Qisun He, the Bluetooth headset is detected, click it, and the display will be "connected".
6. Press the button in the left plug earphone to turn on noise cancellation.
Bluetooth headset is to quietly focus on the hand-free headset application, so that users can avoid the stumbling of annoying wires and easily talk in various ways. Since the advent of Bluetooth headsets, it has been a good tool for mobile business people to improve efficiency. Bluetooth is a low-cost, high-capacity, short-range wireless communication specification.
The Bluetooth specification operates in the microwave frequency band, with a transmission rate of 1m bytes per second, a maximum transmission distance of 10 meters, and can reach 100 meters by increasing the transmission power. Bluetooth technology is open to the world, with good compatibility on the global scale, and the whole world can be connected by low-cost invisible Bluetooth networks.
Noise cancelling headphones are mainly divided into two kinds according to the principle: one is passive noise cancellation (passivenoise-cancelling) headphones, the other is active noise cancellation (activenoise-cancelling) headphones 1, passive noise cancelling headphones, also known as physical noise reduction, in fact, it is to do sound isolation is through the sound insulation materials or special structures on the headphones, and try to isolate noise mainly in-ear earbuds and full-cover earphones, but due to the overly tight design, Long-term wear will make the ears swelling and painful, excessive sound pressure will even affect the hearing 2, active noise reduction headphones, through the noise reduction module in electronic noise reduction, is set up in the earphones A special noise reduction circuit is generally through the audio receiver (such as a micro microphone) and the anti-noise output chip, through the reception, analysis of the frequency of external noise and the opposite frequency, mutual weakening or canceling, so as to achieve the purpose of shielding noise Generally speaking, active noise cancelling headphones, the headphones themselves have an "ear", "ear" It is used to listen to external noise, because its "ear" is very close to our cochlea, the ambient noise it hears is very close to the noise that is about to reach the human ear, but there is still a slight deviation; After receiving the noise, the internal electronic noise anti-noise chip will calculate the audio (set to a) and the audio of the noise (set to b) of the file itself, and the actual audio broadcast is actually a b, and the noise b will still be transmitted to the cochlea, then the audio received by the cochlea is a b b a extended information: noise cancelling headphones refer to a kind of earphone noise reduction headphones that use a certain method to reduce noise, using active noise control, different from the passive sound isolation of general headphones, its principle is: >>>More

magus？Looks like hype. In the case of Bose, the sound quality is average, but the three frequencies are relatively positive, and the noise reduction ability is very strong, but it seems to be over budget.
Yes, noise cancellation is an essential feature in games. Noise is canceled out by emitting sounds of the opposite wavelength to the outside sound. For example, Daryou Darknight Streamer EH925 Noise Reduction Edition ensures the clarity of teammates' calls in the fierce game battle, and turns on environmental noise cancellation through Daryou software, canceling external noise, and creating a quieter chat atmosphere.
Taking AirPods2 as an example, the solution to the loss of Apple's Bluetooth headset is as follows: >>>More
