What to do if the mobile phone headset is distorted, the bluetooth headset is distorted

What brand of mobile phone is obvious, the decoder problem basically can't be changed If you use backgammon and so on, such ** mobile phone is distorted, that is the problem of headphones (backgammon oppo is Microsoft's *** processing software) or *** problem After all, *** is a lossy audio file If you use a high-end product like iPhone4 It supports lossless audio format (a song is about 20m to 30m), so if it is still distorted, it is definitely a problem with headphones If you want me to see it, it's a problem with your mobile phone itself, and the interface is unlikely to be distorted (even if there is only a trace of copper wire connected, the sound quality can be guaranteed) You either check the internal audio output port of the mobile phone to see if there is a false connection (poor contact, the wire, etc., may directly change the sound quality) or re** song and then try to change the headphones If it doesn't work, it's a problem with the decoder itself Basically, no one goes to repair the money to rebuy a **mobile phone, I hope it helps you.

Distortion: The output of the device does not fully reproduce its input, resulting in distortion of the waveform or increase or decrease in signal components. The distortion of headphones is generally very small, and its total harmonic distortion (THD) is less than or equal to 1% at the maximum withstand power, which is basically indistinguishable by the human ear, and much smaller than the distortion of speakers.

Pivoful Punofi Bluetooth headset has done a good job in this regard, and the distortion rate is relatively low in China.

The root cause of the poor sound quality of Bluetooth audio devices is very simple, because the audio signal is compressed by lossy coding during the transmission process. In order to achieve a larger compression ratio and a smaller amount of data during compression, lossy coding will discard some of the original information in the audio signal. The compressed information is insufficient, resulting in distortion in the process of decompression and restoration.

At present, the sound quality of Bluetooth transmission may be limited by two aspects. First of all, because of the protocol, Bluetooth transmission of audio mainly relies on the A2DP (Advanced Audio Distribution Profile) protocol, which specifies the conditions that must be met when audio is transmitted over Bluetooth. If the A2DP protocol is not used for transmission, the receiver will not be able to recognize the audio data sent by the sender.

The protocol, which was established in the early days of the Bluetooth standard, did not take into account the current situation, and limited the amount of data that could be transmitted, so that the audio data could only reach about 328kbps. So even though the new Bluetooth standard can bring higher transmission speeds, these protocols are not updated and their use will still be limited by the speed they limit.

Secondly, Bluetooth is also based on the frequency band, and WiFi, wireless keyboards and mice will use this frequency band. When the data is transmitted, there will be some interference, resulting in intermittent sound, especially for audio devices, which can have a noticeable impact on the user experience.

Hello, I have seen your question and am sorting out the answer, please wait for a while Hello dear, the headphones are too bad, or the phone does not support your headphones. I've used those headphones before, so it's nice to get a new one.

Suddenly the phone is plugged into the headphones, the sound is good, and the noise is very loud without headphones, and it is okay just now, and it is all of a sudden.

Hello dear, it's the small speaker that the phone is playing outside is too broken, and there will be broken sound and noise when the volume is loud. It is very difficult for the small speaker on the mobile phone to achieve high power without breaking the sound. The sound of the earphones is actually very small, only about one-tenth of the external speaker, so there is generally no broken sound.

It's the same with the **, it's the phone that has a problem.

Either the horn is broken.

Licensed goods can go directly to the after-sales service for a new one, it is recommended to change the equipment and try again, and the general socket is not compatible.

This kind of problem should be caused by the mismatch between the earbuds and the phone.

It should be a problem with the headphone jack.

Landlord, are your headphones good now? I'm having the same issue with my Magic Headphones.

Does anyone know what's going on? Ask for help!!

What to do?

There are 4 reasons, first, the so-called headphones that are not shocked, the diaphragm may be artificially damaged, if it is in-ear, it may be that the earphone shell is not tightly sealed, second, check your headphone jack and plug to see if it is not plugged in, and then see if there is anything dirty on the headphone plug that causes contact problems.

Third, check whether the wire at the root of the headset has been injured, and fourth, change the device, such as a computer, to try if there is a problem with the headset, if there is no problem, it is a problem with the mobile phone socket or the device.

Is there no sound from your headphones used on your computer? It is possible that your headphones are not standard and are not supported! You can change to a standard good headset and look at it.,It's almost a jack problem with your headphones.,And mine,.
