That's the problem with the headphone jack.

Advantages of headphones: When I first got started, I heard that this is an entry-level artifact, maybe the ears are relatively wooden, and I don't think it's particularly brilliant when I use it, but after a long time, I found that there is indeed a mellow feeling. I tried my classmate's recording engineer and tried the magic sound in my ears, but I think that in addition to the heavy bass, it is indeed a good headphone.

Disadvantages: The line is relatively short, and I don't know if it's a quality problem, the arc rubber ring on the top of the head is not strong enough, and sometimes it will fall off a little and clip the hair.

Summary: As the review said, three-frequency balance, at first glance, I think that's what it is, but after a long time, I can't do without it.

It may be caused by a short circuit caused by moisture in the headphone jack of your mobile phone, or due to a foreign object that causes poor contact between the contacts in the headphone jack, which can be cleaned with a cotton swab or paper towel; If the problem still cannot be solved, it is recommended to check and repair at an after-sales service point. Here's a closer look:

1. In general, this is caused by the dampness of the mobile phone or the water entering the headphone jack, try to throw out the water in the earpiece, and then gently screw in the water with a cotton swab, and then use the hair dryer to turn on the hot air and slowly dry the remaining moisture, and restart the mobile phone;

2. It may also be due to poor contact in the headphone jack of the mobile phone, or it may be caused by foreign objects inside, use a cotton swab or paper towel to clean it up;

3. If it still can't be solved after cleaning, it may be caused by the failure of the headphone jack, and it is recommended to take the mobile phone to the after-sales maintenance point for inspection and repair.

If the mobile phone is not plugged into the headphones, the mobile phone has this prompt, it is recommended:

1).Turn off your phone and restart it.

2).Eliminate software factors: back up your phone data (**book, short message, multi** files, etc.), and restore factory settings.

3).The switch reed inside the headphone jack is dirty and rusty or loses its elasticity, resulting in the headset detection switch cannot be disconnected normally, and the mobile phone system will mistakenly judge that the headset is still plugged in, so the headphone mode will be displayed. You can try to plug and unplug the earphones a few more times, and you can also twist the tissue into a small stick shape and gently screw it into the jack in the direction of the twist, bringing out the dust, and see if it can return to normal.

If it does not return to normal, you will need to replace the headphone socket.

Reasons and solutions for the headphone mode to be displayed when the phone is not plugged in.

1. Foreign objects enter the earphones.

This situation is mostly related to the user's sloppiness and carelessness, and the solution is very simple, find a relatively thin thing, clean the headphone jack, and clean up the dirt inside.

2. The mobile phone is flooded and causes a short circuit.

In this case, you can go to a repair shop and have a professional repair it; If you can disassemble the phone yourself, you can also repair it yourself.

3. The tail plug is damaged.

See if it's because the copper pieces of the headphone jack are stacked on top of each other, and if so, you can solve it by picking it open directly with a needle.

4. See if the tail plug of the mobile phone is moldy and rusty.

Many mobile phones may be moldy and rusty due to the humid environment of use, coupled with foreign objects inside, in this case, just brush it with a brush.

5. The protective tube of the motherboard is damaged.

This is a serious hardware problem and should be repaired by a professional.

6. Software problems.

You can try plugging and unplugging the headphones to see if they are still in headphone mode, and if so, you can go to the profile mode settings. If the above steps don't work and you can't set it up, then restore it to factory settings. Generally, if there is a problem with the software, restoring the factory settings can mostly solve it.

No headphones are plugged in to show headphone mode, what's going on.

There may be dust on the headphone jack and charging port, and there may be virtual soldering of the IC module.

The phone's headphone jack was short-circuited, causing the CPU to think that you were plugged in with headphones, so the speaker was not working. The battery heats up and the battery life is short, which is also caused by a short circuit.

You have broken the earpiece and speaker, if you have strong hands-on ability, you can disassemble it to see if it is caused by loose soldering joints. Just repair the weld. If you don't have strong hands-on ability, send it for repair.

No water or sweating too much, I used to accidentally drink a Coke bottle on the phone also quickly through ** with you a wrong solution: remove the dry wind and clean it with alcohol, hoping to help you.
