10 things to know when buying Headphones

Headphones are an essential piece of technology that has been evolving since their introduction in the late 1800s. From the very first headphones to today’s new features and different designs, they have undergone many changes throughout time. Here is a list of things you should know before buying your next pair.

“How to buy earphones guide” is a helpful article that provides 10 important things to know when buying headphones. It also includes the “Must Have” text.

Purchasing headphones is not as simple as it was a few years ago. Headphones have evolved into more than simply listening devices as technology has advanced. Headphones have evolved into gadgets that enhance the functioning of your phone by including functions such as active noise cancelling and step counting. 

However, because of this increased capability, headphones have been connected with a lot of technical jargon, significantly complicating the process of finding the proper set of headphones. So, how do you go about choosing the best headphones?

So, you de-mystify all of the technical language around headphones and consider what you want from them. However, before we get into all of the technical jargon, it’s important to understand the many types of headphones on the market.

Although earbuds and headphones utilise comparable technology, this essay will focus on over-ear headphones.

To make music seem more pleasant, most consumer-grade headphones boost particular areas of the audio spectrum. Sound coloration is a method utilized by headphone makers. Sound coloration is not used in the case of studio headphones.

As a result of the flat frequency response, music producers can detect any defects in the song. Studio headphones are designed to be as accurate as possible when it comes to reproducing sound. As a result, they use high-end electronics and have specified circuitry that may be found in consumer-grade headphones.

The impedance of studio-grade headphones is increased as a result of all of these design limitations. As a result, as compared to consumer-grade headphones, most studio headphones have a greater impedance. In the next portions of the essay, we’ll go over this in further detail.

If you’re a player, you’re well aware that gaming headphones sound nothing than conventional headphones. Gaming headphones are created with gamers in mind, whether it’s the RGB illumination or the bass-heavy sound output.

These headphones are intended to reduce latency and boost surround sound for a more immersive gaming experience. Furthermore, gaming headphones have specialized microphones with noise-cancelling capabilities to enable gamers communicate with their teammates in busy locations.

The majority of us have used consumer-grade headphones at some point in our lives, and they are the most common in the business. These headsets are intended to work with mobile devices and have a low impedance since they are powered by low-power electrical devices.

Not only that, but consumer-grade headphones are designed to be mass-produced, and the electronics used in them are inferior to those used in studio-grade headphones. Furthermore, each manufacturer controls the sound signature differently, and headphones from various manufacturers respond differently to the same music.

Many audiophiles have brand loyalty and prefer some brands over others as a result of this.

Now that we have a better understanding of the many headphones on the market, we can go further into the technical features.

Any electrical equipment we use has a certain amount of resistance. This resistance to the passage of electrons in any device is known as impedance, and in a headphone, this resistance to the flow of current is known as impedance. The impedance of headphones is usually between 8 and 600 Ohms; Ohms is the unit of measurement for impedance. 

Electrostatic drivers have high impedance values of up to 100,000 Ohms, necessitating the use of special amplifiers.

The majority of consumer-grade headphones have a 32 Ohm impedance, therefore if you’re searching for consumer-grade headphones, you shouldn’t be concerned.

On the other hand, if you’re looking for a professional set of headphones, you may get the same pair in a variety of impedance formats. The Beyerdynamic DT 770 pro, for example, is available in three impedance configurations: 32 Ohms, 80 Ohms, and 250 Ohms. So, out of the three, which one do you choose?

The answer to this issue is more dependent on how you intend to use the headphones than on their sound quality. If you want to use the headphones with a mobile device, the 32 Ohms version is recommended since it does not need extra amplifiers to attain maximum volume.

If you’re a music producer or a sound engineer, the 250 Ohm version would be a suitable match. The 80 Ohm version is compatible with mobile devices and amplifiers, making it ideal for sound editing and recreational listening.

What effect does impedance have on your listening experience?

The amount of power required to obtain maximum loudness is determined by the impedance of a pair of headphones. A higher impedance headset takes more power to attain its maximum loudness, while a lower impedance headphone accomplishes it with less power.

External amplifiers are required to power high impedance headphones as a result of this. Higher impedance headsets feature greater sound quality because they are manufactured with superior materials and have better voice coils.

When it comes to the sound quality of your headphones, impedance has no bearing on how they sound. Professionals that utilize high power amplifiers and mixers to assess their recordings instead use higher impedance headphones.

If you’re thinking about getting a professional high-impedance headset, be sure the amplifier and headphones have the same impedance. This impedance matching allows you to get the most out of your headphones.

The loudness of a headphone is determined by its sensitivity. It specifies the sound pressure that a headset produces at a given frequency and input power. In most applications, sensitivity is determined at 1 kHz and 1 milliwatt of input power.

Simply simply, headphones with a greater sensitivity will sound louder than headphones with a lower sensitivity. So, if loudness is important to you, paying attention to a headphone’s sensitivity is a smart idea.

Have you ever wondered how your device’s electrical impulses are turned to sound? The driver in your headphones is in charge of completing the work. The transducer, also known as the driver, turns electrical impulses from your mobile device into sound waves.

There are several sorts of drivers, and the following is a list of them:

• Dynamic or moving coil drivers are the most common kind of drivers, and they are used in the majority of headphones. To generate sound waves, these drivers use a diaphragm and a system of permanent and temporary magnets. They have the greatest price-to-quality ratio when compared to other drivers on the market. However, in large quantities, they are vulnerable to distortions.
• Electrostatic drivers: When it comes to drivers, electrostatic drivers are unrivaled. They are the best on the market, and they create music using electrostatic principles. However, these drivers are expensive and need specific amplifiers to operate. As a result, headphones with large drivers are not portable and must be used in a studio situation.
• Planar magnetic driver: These drivers work on the same concept as dynamic speakers, but with superior sound quality and less distortion. When compared to dynamic headphones, these headphones take more power to drive and are heavier and more expensive.

Size of the driver

Another feature that virtually all headphones have is the driver size. The diaphragm size is referred to as the driver size. The diaphram travels to and fro in response to an audio source, creating sound waves. For headphones, the diaphragm size ranges from 20 to 50 millimetres, with a larger diaphragm producing a louder sound. The reason for this is because a larger diaphragm can displace more air molecules, resulting in improved bass.

However, a larger diaphragm does not imply superior sound quality, since larger diaphragm headphones have problems reproducing high frequencies.

What are the best drivers to get?

Electrostatic drivers are the greatest on the market if you’re seeking for the best. A set of high-end electrostatic headphones, on the other hand, may cost anywhere from $2,000 to $5,000. Not only that, but you’ll need an external amplifier to power it, so they aren’t the ones for you if you’re searching for anything portable.

If you’re on a budget, dynamic drivers are generally your best pick, but if you have a little more cash and aren’t looking for anything ultra-portable, planar magnetic drivers are a good option.

As previously stated, no two headphones are alike, and various manufacturers use different sound coloration methods to improve the sound quality of their products. So, how can you figure out how a set of headphones is tuned and which frequencies they excel at? 

The frequency response of a set of headphones, on the other hand, may aid in this understanding. Most headphone specs provide a frequency range that they can reproduce.

Humans can only hear noises in the 20 Hz to 20000 Hz range. 

In most situations, the frequency response of headphones is listed on the spec sheet as the human hearing range. However, some headphones have a predetermined frequency response ranging from 4 Hz to 40,000 Hz. Humans cannot hear frequencies over 20,000Hz, hence this wider range of frequency reproduction has little bearing on sound quality. 

Simply defined, a headphone’s frequency response graph depicts the amount of amplification it provides at various frequencies. So, if you look at a headphone’s frequency response curve, you can see how it performs in various frequency ranges. 

Without using the headphones, the frequency response of a headset may help you grasp its sound character. If you can’t locate the headphones in a shop near you but want to hear how they sound, this is a good option.

Most headphone datasheets don’t provide this information, so you’ll have to depend on third-party reviews to find it. 

What happens when external noise is added to the mix? A set of headphones may sound fantastic in a calm area, but what happens when external noise is added to the mix? If noise from outside may reach your ears, the quality of the music may suffer significantly. Here’s when noise-cancelling technology comes in handy.

Simply simply, noise-cancelling technology keeps undesirable background sounds out of your ears. In headphones, there are two forms of noise cancellation: passive and active noise cancellation. 

Noise-cancelling headphones are passive noise-cancelling headphones.

Passive noise-cancelling, as the name implies, removes noise from the ears using passive or non-electronic components. Earcups with noise-isolating material and closed-back designs are used to block out ambient sounds.

This kind of noise reduction works well for removing high frequencies but not so well for removing lower frequencies. As a result, sound from jet engines inside aircraft cannot be suppressed using this method. 

Transparency mode and active noise cancellation

Active noise cancellation, unlike passive noise cancellation, removes external noise using electronics. Microscopic noise is removed using digital signal processors and microphones. In the lower and mid-band frequencies, this method works effectively. There are three kinds of active noise-cancelling technology, depending on where the microphone is placed. 

• The microphone is positioned on the exterior of the headset in feedforward active noise cancellation. As a result, it takes up outside noise, which is subsequently removed by the digital signal processor, leaving the consumer with clear audio. 
• The microphone is inserted into the earcups for feedback active noise cancellation. The microphone has a greater noise resolution with this arrangement, although the lower frequencies of the music may suffer. 
• Two microphones are incorporated in the headphones for hybrid active noise cancelling. One is on the inside, while the other is on the exterior. Among all the designs, this one has the finest noise cancellation.

Transparency mode is available on most active noise cancelling headphones. This function is the polar opposite of noise cancellation, and it allows users to hear what’s going on outside.

Also, since the electricity from the headphone port is insufficient to power active noise cancelling, it is only found in headphones with batteries. If you can’t live without active noise canceling, wireless is most likely the best option.

Should you invest in active noise cancelling headphones?

If you travel often, a set of headphones with active noise cancellation will revolutionize your journey. However, if you’re searching for headphones for a studio, you’ll probably be able to find a set without active noise cancellation.

It’s also important to remember that active noise suppression only works at lower frequencies. This implies it can only suppress low-frequency sounds like those produced by an airplane engine, but not higher-frequency noises like those made by a newborn wailing.

Wireless headphones have saturated the market thanks to advancements in Bluetooth technology. Furthermore, the lack of 3.5mm connectors on most smartphones and tablets has prompted users to switch to wireless headphones. Are wireless headphones, on the other hand, superior to their tethered counterparts?

When it comes to sound quality, wired headphones are superior than their wireless counterparts. Bluetooth technology is to blame for the loss of sound quality in wireless headphones.

Audio signals are transferred via the headphone jack while using wired headphones. As a result, the audio signals have a lot of bandwidth and can send a lot of data to the headsets.

Wireless headphones, on the other hand, are a different story. Audio files must be compressed in order to be sent to the headphones using Bluetooth technology. The audio quality suffers as a result of this. Lossless music cannot be played using Bluetooth headphones because of this.

Wireless headphones, although not as good as wired headphones in terms of sound quality, provide users with more mobility since they are not linked to their gadgets by cables.

This mobility, however, comes at the expense of batteries, and owning a set of wireless headphones entails the duty of keeping them charged. Although keeping your headphones’ batteries charged might be a pain, they are necessary for features like active noise cancellation.

What kind of headphones should you buy?

If you’re an audiophile who like to listen to high-quality music, wired headphones are definitely the preferable option since they can also play lossless music. Getting a set of wireless headphones, on the other hand, is a better idea if you find yourself traveling and listening to music on the move.

Since its introduction in the late 1990s, Bluetooth technology has advanced in leaps and bounds. From Bluetooth version 1 in 1999 to Bluetooth 5.2 in 2020, Bluetooth has come a long way, but what exactly is the difference between these many Bluetooth technologies, and is it worth upgrading? 

Despite the fact that there are multiple Bluetooth versions, most gadgets on the market come with Bluetooth version 4 or 5. As a result, we’ll compare the two and look at some recent Bluetooth 5 variants. 

When it comes to Bluetooth technology, there are three key characteristics for each user to consider: range, bandwidth, and battery consumption.

When compared to Bluetooth version 4, Bluetooth 5.0 delivers double the bandwidth. This makes it easier to link devices and improves sound quality. Not only that, but Bluetooth 5 has four times the range of Bluetooth 4.

Furthermore, as compared to version 4, Bluetooth 5 consumes less power. So, if you have a set of Bluetooth version 4 headphones, upgrading to Bluetooth 5.0 is absolutely worth it. 

If you intend on purchasing a Bluetooth 5.0 headset, you must first ensure that your streaming device supports the technology.

Bluetooth 5.2 is the most recent version of Bluetooth technology.

Although Bluetooth 5.0 provides several enhancements over version 4, Bluetooth version 5.2 has recent advancements that are well worth the upgrade.

To begin with, Bluetooth 5.2 has low-energy audio, which allows audio to be sent across low-power channels. Audio files were previously sent through Bluetooth classic, which required more power to transmit. Music files will be transferred with improved quality and less battery usage using low energy audio.

Aside from that, Bluetooth 5.2 has multistreaming and broadcasting modes.

Bluetooth 5.2 was introduced in early 2020, and technology like low energy audio will take time to reach the market.

As it is, music from your smartphone can’t be transferred to your wireless headphones. To send audio files to a Bluetooth device, they must be compressed. This job is performed using several codecs (coders-decoders), and the compression efficiency might affect the music quality.

There are a variety of codecs on the market, and a codec with a larger bitrate provides better sound quality. The following is a list of audio codecs and associated bitrates.

Except for SBC, all other codecs are proprietary and produced by Apple (AAC), Qualcomm (aptX), and Sony (Sony) (LDAC). As a result, it’s crucial to double-check that both devices are compatible with the codecs. If this is not the case, SBC will be used as the default codec.

Higher bitrate codecs provide greater sound quality, but they sacrifice connection. As a result, using a high bitrate codec over a long distance might cause audio to drop.

In addition to these codecs, Bluetooth 5.2 will provide L3C, a new codec that will allow audio to be transmitted across lower-power channels.

If you’re thinking about obtaining a set of wireless headphones, you should think about how long they’ll last. The majority of the headphones on our list can last up to 40 hours on a single charge.

When it comes to batteries, it’s also crucial to keep an eye out for technologies like fast charging, which may help your batteries charge up quicker. Not only that, but if you acquire a set of headphones with active noise cancelling, be sure to check the battery life they provide while ANC is switched on, since it affects battery life.

When it comes to headphones, the majority of them are not water resistant. So, if you’re searching for a set of headphones to use while working out, waterproof earbuds are the way to go.

Now that we’ve covered all of the technical aspects of headphones, it’s time to tackle the most essential question of them all. Which headphones are the best for you?

Well, it depends on how you use your headphones: are you a gamer, an audiophile, or just a regular shopper? Do you like electronic music or bass-heavy music?

You’ll be able to choose the ideal pair for all of your requirements after asking these questions and learning about the technical aspects of headphones. Not only that, but it’s crucial to try on a set of headphones since the human ear’s transfer function causes everyone to hear music differently while listening to surround sound.
