5 Things to Know When Choosing Perfect Headphones

Headphones are available in a lot of different styles, brands and prices, which make it hard to find a right pair for you.

Are you aware of the celebrity-endorsed headphones trend? If so, then just be clear that when you open up the spec sheet, things are still confusing. In this article, we’ll discuss in detail the key headphone specifications and why they matter.

1. In-ear Headphones

The first and the foremost are the in-ear (canal) headphones. These ear pieces fit directly into your ear canal, also called as in-ear monitors. In-ear headphones offer two significant benefits to the wearer. First of all, they deliver excellent sound quality because it’s nearer to the ear drum. Secondly, it fills out way into the ear; that’s why it’s quite useful in sealing out external noise.

These headphones are available in different sized tips, so you can choose accordingly. If you want to attain the best performance, it’s important to get the right size.

2. On-ear Headphones

These headphones are also called supra-aural headphones, which sits on the top of the ear. Similar to the in-ear headphones, they also send the sound straight into the ear canal, but can’t block out outside noises. Moreover, people sitting next to you can hear what you’re listening to.

A lot of people find on-ear headphones more comfortable as they don’t trap heat on your ears, unlike over-ear headphones. But clamping might be an issue for some folks out there as they may complain of headphones squeezing too tightly and irritating their ears. Try to find a pair that sits well.

When it comes to sound quality, on-ear headphones offers you a good balance of high sound quality along with a decent level of portability.

3. Over-ear Headphones

Over-ear headphones are also called circumaural headphones as they encase the entire ear. They are large; that’s why also contain a large driver with enhances bass performance and louder volume. When it comes to positioning, it is placed far away from the ear and produces a more spacious sound, which resembles the sound of the speakers.

4. What Are Drivers?

The driver of a pair of headphones is believed to be a critical component. It can convert an electrical signal to sound pressure. In other words, you can say that it produces sound.

Drivers are of different types, but all of them primarily contains magnets, a diaphragm and voice coils.

The diaphragm vibrates due to these components and then these vibrations produces sound waves, which we interpret as sounds.

On a spec sheet of a pair of headphones, the driver is indicated by the diameter of the diaphragm is mentioned in mm (millimeters). Most of the time, the driver size is directly proportional to the sound quality, particularly when it comes to bass performance. Take over-ear headphones for example. A 40mm driver proves to be a good size for sound quality.

On the other hand, in-ear headphones are smaller in size, so can’t fit a larger driver easily. That’s why some technical experts use the dual-driver approach, in which your headphones have two drivers; one for bass and the other for mid and high frequencies.

5. Paying Attention to Sensitivity and Sound Pressure Level

When it comes to the SPL (sound pressure level) or sensitivity; both terms are related. It indicates the loudness of your headphones. You can explain the sensitivity as something that measures how competently an electrical signal is converted into an acoustic signal. Similarly, sound pressure is how you measure the sensitivity.

Some of the top Bluetooth headsets lie within the range of 80-120 dB SPL/mW. To provide some context; a shouting voice is around 105 dB, regular city traffic 80 dB and the plane take off 135 dB.

Can Technology have Biases Like Humans?

Can Technology have Biases Like Humans?

Technology has taken a vantage leap in providing solutions for man. Before now, technology used to appear complex and would require a great deal of expertise to handle solutions available. Today, we have technology applicable in the simplest human activities as smart products with intelligent algorithms powering them as they make error-free judgments and provide intelligent and analytic solutions.

Does technology have all the answers?

This article from Credit Suisse, tells us that technology does not have all the answers because it has been found to exhibit “similar biases,” as humans. No one can discredit the impact of technology, but it is not totally free of human input and this is the reason we experience these biases in many areas we have technology holding foot.

Creating technological solutions transparently

This article suggests that the process of creating technological solutions be made transparent and subject to contribution from many people who would end up as users of the product – male, female, young, old, learned, unlearned and all other preferences as we have them. It also underscores the importance of having women on product development teams. This approach is not sure to eliminate all forms of bias, but it is a good way to start in order to appraise the full benefits of technology.

Technology as the connecting tool

Technology so far has been a major connecting tool amongst us humans. It is used and appreciated by all regardless of race, language and sex. In order to keep it less subjective to these arguments about human biases. I believe we should gather opinions on products and solutions before making them available to the public. This could be done by gathering input from intended target users and receiving feedback across the stages of production.

“Recognizing the problem is a start…success will depend on inclusive technologies that meet this vast untapped market.” This cannot be more apt especially at a time when we look up to technology for solutions. We should not muzzle our progress with technology by battling algorithm bias. The first way to avoid this battle is by reading this article here.
