Headphones have become a staple piece of tech equipment. Almost every person uses some sort of headphones at least occasionally.

They are widely available at stores like Walmart and Target, as well as online sites like Amazon and eBay. There are a huge variety of types of headphones, including earbuds, noise-canceling, studio monitors, and earphone variants.

All of these different types have one thing in common: they are all electromagnets. Yes, that is right! Even though you can’t see them, all headphones are tiny electromagnets. This is not a fact that is discussed often, but it is true!

How are they electromagnets, you ask? Well, let’s dig into the specifics so you can understand this fact better. This article will discuss all the details about how headphones are electromagnets.

How do they work?

Headphones work by using a electromagnet. Inside most headphones is a metal core, usually aluminum. This is where the speaker is located.

Around the core is a wound wire. When an electric current is run through the wire, it creates a magnetic field. This magnetic field is controlled by the strength of the electric current running through it.

The stronger the current, the stronger the magnetic field. This allows for different levels of sound to be created. When plastic or leather covers are placed over the wires, they act as amplifiers for the sound.

The shape of the plastic or leather helps direct the sound towards your ear, allowing you to hear what you are listening to more clearly. How cool is that?

You can also have headphones without this feature, but they will not provide better sound quality than normal earbuds.

Do all headphones use electromagnets?

No, actually headphones come in a few different forms. The most common type of headphones is over-ear or ear-covering headphones.

These have an internal housing for the speakers and an external cover that covers your ear. The wire that connects the two is usually coiled for storage.

In-ear headphones are just what they say- they insert into your ear canal! These are very common among athletes because they block out more noise than over-ears do.

Finally, there are Bluetooth headphones which do not have any wires at all. These sync with your device via wireless signal and therefore do not need any internal wiring either.

What are the advantages of using electromagnets?

Aside from being able to be turned on and off, electromagnets can also be adjusted in strength. This is very important when designing headphones.

If the magnet is too strong, it will pull the earpiece away from the phone or computer, breaking the connection. If it is too weak, it will not adequately produce sound.

The strength of the magnet can also be adjusted so that when you transition from listening to music to a phone call, the connection is not lost. In addition, stronger magnets help to preserve battery life due to less energy required to maintain their state.

Other uses for electromagnets in headphones include wireless charging capabilities and adjustable noise cancelling. Wireless charging is easily integrated into most headphones by placing a magnetic field generator under the cushion of the headphone frame.

What are the disadvantages of using electromagnets?

While headphones are a great way to isolate yourself from the world and enjoy your favorite music, listening to music too loudly can be very dangerous.

According to the United States Department of Health and Human Services, more than 1 in 8 people aged 12 to 22 say they listen to music at least half of the time at a level that would be unsafe for their hearing.

This is because people get used to the sound of music and do not adjust the volume higher or lower depending on what changes.

When listening to music through headphones, you are actually only hearing one side of the sound. The other side is being blocked by the headphone speaker itself.

This makes it easier to listen at higher volumes without realizing how loud it really is. As we said before, this can lead to permanent hearing loss due to exposure to high levels of sound.

The Department of Health and Human Services recommends that you turn down the volume on your devices by at least 50% or use earbuds instead of headphones to reduce your risk of hearing loss.

What materials are used in making headphones with electromagnets?

When looking for headphones, you will find many different types. The main two features that are sought after are sound quality and style. A third feature that is being looked for is magnet strength.

Sound quality is determined by how well the headphones reproduce sound. This is dependent on the specifications of the materials used to make the headphones.

Style is obviously depending on what design and color the headphones are. They must also match your personality!

The magnet strength refers to how strong the electromagnet in the headphone is. The higher the strength, the better quality music you will get out of them.

When buying cheap headphones, it is hard to tell if they are made with high quality materials or not.

Are there any disadvantages to using headphones with electromagnets?

Yes, unfortunately, there are some disadvantages to using headphones with electromagnets. First of all, listening to music or podcasts at a higher volume can lead to hearing loss.

In addition, since you are listening to music on your phone, tablet or computer, you are also exposed to EMFs. These EMFs come from the device and affect your cell signal.

By using headphones, you are blocking out this radiation and consequently, your brain is not being conditioned by the signals.

Studies have found a correlation between long-term cell phone use and brain tumors as well as other neurological disorders. Because of this, it is best to limit your cell phone use and switch to wireless headphones.

Another disadvantage is that people may listen to music at a lower volume when using wireless headphones but still for a long time which can lead to habituation.

What about wireless headphones?

Along with the ever-increasing demand for wireless everything, there has also been a growing market for truly wireless headphones. These are earbuds that do not have any connecting wires between them.

How are these made? While most companies do not discuss their manufacturing processes, some reveal some details.

Most use similar methods: each earpiece has its own mic and small processor, and they connect to a shared wireless chip that connects to your phone. Some use Bluetooth connection, others use Wi-Fi connection. Some even have both!

The biggest difference seems to be how much battery life you want. Companies try to balance the length of the battery life with the weight of the headphones- the lighter they are, the smaller the batteries can be. Some even use special materials to preserve battery life.

How much power do they have?

Although the average person will only consider two main factors when buying headphones, there are actually quite a few. The two main ones being sound quality and noise cancellation.

Sound quality is pretty self-explanatory. You want to buy headphones that have good, crisp sound. That happen to be tailored to your listening taste!

Noise cancellation is how effectively the headphones block out external noise. This is a pretty important feature if you are looking to spend money on headphones. How do they do this?

They are electromagnetic shields that actively cancel out external noise. How much power does the headphone require? It depends on the type of noise cancellation you choose.

Wearing headphones to bed has become a common practice, especially among young adults. With the rise of listening to music via smartphones, people have more access to music than ever before.

Music is a great way to relax and prepare for sleep. Some studies have even shown that music can improve sleep quality!

Having headphones in your ear already makes it difficult to hear outside noise. Adding music onto that makes for a very peaceful sleep.

The problem comes when people do not realize the risks of sleeping with headphones in. The most dangerous situation is when someone passes out and does not hear any emergency calls or noises.

Aside from that, pulling the headphones out while asleep can cause other issues. If they are wrapped around the neck or wrists, they may become tight and impede blood flow. If they are on the floor, then they may cause you to wake up due to feeling off balance.

There are ways to sleep with headphones on safely! This article will go over some of those ways.

Set a loud alarm

If you have trouble falling asleep with headphones on, then try setting a loud alarm. When the alarm goes off, you can take off your headphones and fall asleep!

This is a trick that many people use to help them sleep in uncomfortable places. By sleeping in a different place, your body recognizes that it is safe to sleep and you will get a good night’s sleep.

Sleep is one of the most important things for our health. If you struggle to sleep because you cannot listen to music or podcasts before bed, then try using this tip to help you fall asleep easier.

Some people may find it difficult to coordinate their music or podcast listening time with their bedtime. If this is the case, then try going to bed a few minutes earlier or later so that you can listen to your music or podcasts before bed.

Do not use loud music

While this may seem like a good idea, music or noise in general will keep you awake. Why?

Because you have to listen to the music or noise, your brain will not process the fact that you are asleep.

The fact that you are listening to something means that you are awake-your brain knows this and does not want to stop processing that fact.

To test this theory, try going to bed without music or noise and see how well you sleep. Then try sleeping with music or noise and see how well you sleep again. You will notice a difference!

It is best to have quiet, soothing music or no music at all when going to bed. Your brain will process that you are sleeping and will let down your guard so to speak.

Keep the volume low on your headphones

Although this may seem self-explanatory, it’s important to note that the volume on your headphones should be low. As mentioned before, there’s a risk of hearing loss if the volume is too high for prolonged periods of time.

It can be difficult to determine the appropriate volume for sleeping with headphones on, but it’s best to play it safe and have a low volume.

Experts recommend setting the volume no higher than 60% of the maximum output provided by the manufacturer. This way you will still hear enough of the music or audio to relax and fall asleep, but you will not be exposing your ears to too much noise.

Keep in mind that this varies depending on the brand of headphones you use. If you are using cheaper ones that do not have high quality sound protection, then you can probably put up the volume more.

Use a soft noise generator

If you find the sound of the ocean or rain too relaxing, then try a soft noise generator. You can find these online and in the app store.

Noise generators introduce a light background noise into your environment, like the sound of rain or surf, but with an adjustable volume. They are great for sleeping as you can adjust the volume to a level that is not too loud or distracting.

They are great for sleeping as they keep your mind focused on the sound instead of thinking about everything that day. They are also very relaxing, so if you are having trouble falling asleep, try investing in one!

If you have your own music and you do not want to lose the quality by reducing the volume, then turn off all of the other sounds on your phone such as notifications and set an alarm. That way, you will still hear your music but not your phone notifications.

Use white noise

If you struggle to sleep because of noise in your environment, you can use headphones to block out other sounds. But how do you sleep with headphones on?

For one, you can choose to listen to white noise instead of music or a podcast. White noise is an almost constant sound that blocks out other noises.

Advertisement

It can be the sound of a fan, the rustle of a paper bag, rainfall, or even the sound of a machine turning on and off. Any of these can help you sleep!

White noise is best because it continues even when you turn off your headphones. You can also choose to listen to white noise before bed, so that it helps you get into a relaxed state before sleep.

Use a sleeping app

If you do not feel comfortable using the two methods above, there is a third option. Use a sleeping app to monitor your sleep.

Many apps offer this feature for free, and some even have it as an ad-free paid feature. By having your phone next to you while you sleep, the app will monitor how long you sleep and how many times you wake up.

This is a great way to start sleeping with headphones on, as the app will tell you how well you slept!

Some of these apps offer more features such as setting a waking alarm based on how well you slept, or tracking how long it takes you to fall asleep each night. These are nice additions if you are looking for something else to track about your sleep.

Keep the headpones on all night

While this may seem weird, it is advised to sleep with your headphones on all night. This prevents you from having to adjust them multiple times in the night, and risk waking up your partner.

Many people have reported success in just putting the headphones on before bed and leaving them on until morning when they get up. This also helps you not worry about getting tangled in wires in the middle of the night!

Some models even have a built-up battery that keeps your music playing until the next morning so you do not have to re-charge before bed.

If you must take them off due to tangling or feeling too wired, just remember to turn them off before bed! Some models have a built-up feature that turns off the music automatically after a set time which can help with this.

Be careful when sleeping with headphones

While it may be tempting to fall asleep with headphones in, or even in your ear, it is not a safe idea. If you need a little white noise to sleep, try keeping the same device on standby with a playlist instead.

Many phones have a built-in setting that turns off the screen and stops all sounds after a certain time period so you do not need to set one yourself.

Removing the ability to hear sounds completely may help you get a better night’s sleep!

Some people use music to help them relax before bed, but if that makes you feel more awake instead, try switching it up. Perhaps listen to some soothing music before bed, or just take out the headphones!

Some people find that sleeping with items in their hair can be uncomfortable, so try moving them before bed.

Noise cancelling headphones have been growing in popularity as they are released in new models and models are updated. They are widely advertised as a necessary travel accessory as well as being a great gadget to have.

Noise cancelling headphones work by using special sensors to pick up ambient noise, a computer algorithm to process that noise, and then completely opposite noise to cancel it out.

This process requires power which is why most high-end headphones are charged via USB or have lithium ion batteries. The longer your headphones last on a charge or battery life, the more expensive they are likely to be.

There are two main risks with noise cancelling headphones: one physical and one psychological. The first will be discussed in this article, the second will be discussed later on.

Learn about noise cancelling headphones

Before you buy noise cancelling headphones, you should learn a little more about how they work and how safe they are.

Noise cancelling headphones use a device inside of them to monitor the noise in your surroundings. This is typically the earbuds that have the noise cancelling feature built into them.

Then, the headphones analyze this external noise and match it with the opposite sound. For example, if there was a loud bang nearby, the headphones would use a similar sound to cancel it out.

This process uses a lot of battery power, which is why most high quality headphones do not have this feature. It is up to you if you want to invest in batteries or spend a little less money for non-noise cancelling ones.

Before buying any pair of headphones, check if they are noise cancelling or not! If you are looking for pure silence, then get non-noise cancelling ones.

Understand the technology behind noise cancelling headphones

Before exploring if noise cancelling headphones are safe or not, it is important to understand how they work. Noise cancelling headphones use microelectronic circuitry to process sound waves.

Advertisement

They use a device called a mic that picks up external sounds, then send that information to a chip that processes the sound. The chip then sends processed sound to the speakers which process and give back internal sound to the user.

The first step of the noise cancelling process is to pick up external sound. The chip then analyzes the amplitude (loudness) and frequency (pitch) of the sound, then sends this data to a processor. The processor uses special algorithms to either increase or decrease the amplitude of internal sounds based on what was picked up from outside sounds.

The second step is to give back internal sounds that are processed based on what was selected by the user on their device.

How effective are they?

Although the main appeal of noise cancelling headphones is the ability to cut out external noise, they are not always very effective.

They work by using a sensor that detects ambient noise, a processor that identifies what type of noise it is, and an actuator that changes the incoming sound wave.

Advertisement

The problem is that if the noise is coming from inside the headphone or device, it cannot be cancelled. Also, if there is too much noise outside the headphone, it will not be fully cancelled.

Some higher-end models use more sophisticated sensors and actuators to better cancel out sound, but at about $300-$400 you are getting the best one! There are some cheap ones that claim to cancel sound, but do not work well.

And lastly, although they can reduce loud noises like plane engine sounds or street traffic, they have trouble with softer sounds like people talking.

What are the dangers?

While noise-cancelling headphones are an excellent tool for people who are overly sensitive to sounds, they have some drawbacks. They can create a false sense of sound safety.

People who wear them may still be exposed to loud noises depending on how much they pay attention to their surrounds. They can also increase stress by making it harder to hear external sounds that may be a threat.

Those with PTSD may experience higher levels of stress and anxiety due to the absence of external sounds. This is why it is important to use ones with a feature that turns off the internal music so you can still hear what is around you.

Others may simply pay less attention to their surroundings because they are focusing on their internal music instead. This can put people at risk if they do not take appropriate safety measures.

Noise-cancelling headphones make it easier for people to shut out external sounds, but only if you’re listening to music.

Are they safe?

Although noise cancelling headphones have several benefits, their safety has been questioned recently. Many people believe that the increased accessibility to silence due to the technology is a bad thing.

Noise cancelling headphones reduce the need to block outside sounds. This may lead to someone being more vulnerable to sound or noise in their environment.

They also may lead to a false sense of security, as someone with noise cancelling headphones in may not be aware of what is happening around them. This is a dangerous combination that could lead to serious consequences.

Those who are in the military, law enforcement, or civilian defense personnel use these headphones for a reason: They make your surroundings quieter so you can focus on what you’re listening to. You become more aware of your environment because of this fact. (This is why they give out free ear plugs at work- unfortunately, they do not last long.

What about Bluetooth speakers?

While the same safety concerns exist for Bluetooth headphones, the ability to play music from a distance via the wireless connection creates another hazard.

If you are listening to music on your phone via Bluetooth and have your headphones in, someone could connect to your device and play whatever music they want.

This is why it is important to keep track of your devices- if someone steals your phone or Bluetooth speaker, they cannot connect to any other devices unless you give them new ones.

While this may seem silly, it has happened before and could seriously disrupt a workout or day off.

Options for reducing noise without headphones or speakers

While noise cancelling headphones are a great tool to have, they are not the only tool. There are a few other ways to reduce noise that do not require spending money.

Noise can be reduced by staying indoors, closing windows and doors and using an air conditioner or fan to get fresh air. This was actually recommended by the World Health Organization during heat waves to help prevent respiratory diseases such as pneumonia.

You can also use ear plugs or ear muffs to reduce sound as well. These can be purchased for a reasonable price at most local hardware stores.

Another way to reduce noise is to stay in groups. If you hear something strange or see something that makes you worried, go with another person or group of people to check it out. This way, you can also help each other if something does happen.

Know when to use them

Noise cancelling headphones are a great tool, but like all tools, they can be harmful in the wrong hands. Since they reduce noise entering the ear, they can also reduce noise entering the ear of someone nearby!

This is not a good thing because you can’t tell if someone or something is too close for comfort when you have headphones on. This could potentially put you or someone else in danger.

Additionally, if you are listening to music or podcasts at a high volume, then people around you will not be able to hear any outside sounds. This could also put yourself or others in danger by not hearing important things such as phones ringing or people calling your name.

Noise cancelling headphones are best used for times when you need to block out all outside sounds. Try to have a setting on your phone that turns off the music after a certain amount of time so that this does not occur.
