Do you have any echo problems with iphone4 using headphones?

I just ran into this issue and mine is 4s. You see, there's a small hole next to the headphone jack, and that's the noise-canceling microphone. Look at the earpiece, how close it is to that place.

So the sound coming out of the earpiece is sent from the noise canceling microphone again. So the other party hears their own echo. The solution is transparent glue.

Or press and hold that microphone while finger tapping **. So there is no more. I'll figure it out again.

Mine too, and every time, I don't know what's going on, how yours solved it, and is there any one that still exists.

A lot of phones do that! And sometimes it's good, sometimes it's bad!! ·

Presumably a problem with the earpiece

Mine is the same way....Everything else is good....I guess the earpiece is broken....Go for a change.

Normal, this is related to the signal, not the mobile phone!

……Is the person you're talking to on hands-free? You try to change someone to call **, this should have nothing to do with your machine.

Occasionally, there is an echo, then it is not a ** problem, it is due to network interference. If there is an echo every time, it is a ** problem, and you can only find a merchant.

This is because the ** noise cancellation feature is not turned on, and the solution is as follows:

1. Click on the iPhone4 desktop icon to open "Settings".

2. Open the settings, find the "General" option under the settings option and turn it on.

3. Then you can see a "Accessibility" in the general options.

4. After seeing the accessibility options, here click on the accessibility function with your hand.

5, then, go to the Accessibility option and find "Noise Cancellation" below it.

6. After finding the ** noise cancellation option, then click the "Open" button behind it, and click to turn it on.

Earpiece problem, looking for after-sales service, my classmate also has this kind of problem.

Try to change the headphones first, and then try to change the volume cable, or not, that is the motherboard, the audio IC is problematic, change this to about 200.

Are the headphones with MIC.

If it is, only Apple's MIC will be recognized.

There are 3 of them that I am using here, and none of them have the problem you mentioned.

After reading what you said--- it only means that the machine you changed can't do it. Let's go back to Unicom and continue to change.

Hope to change to the wood problem IP4 as soon as possible

Re-swap and don't miss the opportunity.

iphone4 hit ** there is an echo of this problem in fact, many users have encountered, many people think that it is the problem of the operator or the other party's mobile phone, in fact, the other party occasionally hears the other party's own echo, it may really be related to the operator (such as signal), but every time you call** can hear the echo, it is your own mobile phone problem.

Let's take a look at the solution for iphone4 to play ** with echo:

Method steps.

Before solving the problem, you must understand the structure of the mobile phone, because you can find a better solution by understanding the general principle of the mobile phone. Take iPhone4s as an example, look at the bottom of the phone first. When I saw two speakers, the one on the right was the one on the right and the one on the left was the microphone, so I made it into a horn shape for the sake of symmetry and good looks.

Look at the top of the mobile phone,The slightly larger round hole on the left is the headphone jack,The small hole located in the middle of the headphone jack and the power button is the microphone,Some people may want to ask why get two microphones,In fact, this design is now more common in other mobile phones,It's called"Double Microphone Noise Cancellation",The purpose is to connect ** outdoors,The microphone on the top can filter the noisy sound,So as to improve the quality of the call。 And the problem of the other party hearing the other party's own call echo is in this small hole.

Looking at the bevel of the mobile phone, the upper part of the mobile phone screen is the earpiece, and then look at the distance between the earpiece and the microphone, whether it is very small. This causes the sound coming from the earpiece when the other party hits ** to be received by the microphone, so the other party can hear his own voice as long as he speaks.

After understanding the above principles, let's look at the solution:

Method. 1. Use headphones. Both wired headphones and Bluetooth headphones are available, which avoids the microphone distance at the top of the phone, but it is not convenient to carry a headset all the time.

Method. 2. Plug the microphone hole next to the headphones, don't worry that the other party won't be able to hear the conversation, because there is another one under the phone. This method seems clumsy, but it is actually efficient, and the disadvantage is that it affects the aesthetics.

Method. 3. If you have a screwdriver to disassemble your iPhone, it is recommended to open the phone and pad some pieces of paper, plastic, etc. under the metal frame corresponding to the hole, which will not affect the appearance and the effect will be better.

When I saw the landlord's problem, I wondered how such a low-level problem could occur in such a bullish mobile phone, no wonder many people said that the iPhone was just a fame collapse.

iPhone 4 is very famous "antenna door", because its antenna is made of metal frame, so the posture of holding the phone when talking determines the quality of the call, buy a bumper shell.

Add a rubber jacket to the iphone4.

There are many reasons for this, most likely due to a delay in the wireless encoder of the phone. If it is a fixed line dialed, it is ** threading is normal.

Two test methods are available.

If there is still an echo, it is not a problem with the mobile phone, it is a problem with the nearby network, if there is no echo, the sensitivity of the mobile phone microphone is too high, find after-sales coordination to replace it.

The second is to find a friend to dial the same ** in the same place, if his mobile phone also has an echo, it is a mobile phone problem. The mobile phone signal is electromagnetic waves, and if there are too many reflectors around, the mobile phone will not be able to receive multiple signals at a time.

It's very simple, network problems, it's okay to have fewer words, adopt hehe.

Try it back on.

Because there is a noise-canceling microphone on the top of the iPhone, which is used to collect ambient sound and cancel out the noise during the call. You put it in your pocket, and this noise-canceling microphone can't pick up noise, so of course it's going to be noisy.

iphone4 now everyone takes it out in their hands, and some people even have one on their left hand and one on their right hand, how can they put it in their pockets, haha.

It is recommended to turn off the wifi function and try again.

The description is a pocket interference signal.

The headset has a microphone. It is possible to hit **.

There is a rectangular switch on the cable near the earphone to control the song: previous, next, pause. Press and hold the one in the middle and there is a small hole in the top that will make a sound, which is the microphone.

I'm glad to answer for you, the headphones have a microphone, and there is a rectangular switch on the headphone cable near the headphones to control the song: previous, next, pause. If you press and hold the one in the middle, there is a small hole in the top that will sound and it will be a microphone, and Apple's products are small and delicate.

Yes, yes, you can also adjust the ** sound of your iPod and the previous song after it.
