This article will list five types of current popular headphones and their specs. Moreover, we will list five recommended suppliers and their products to you.
Introduction:
With a variety of headphones on the market with different features to choose from, there are certain common core specifications such as sound quality which can be used to assess which product is right for you. In this piece, we’ll list five types of the headphones and their specs that you’ll need to know as a business man.
In terms of types, there’re earbuds, over-ear headphones, on-ear headphones, bone conduction headphones and Bluetooth headphones.
Earbuds
Earbuds are also known as in-ear headphones, this type is a classic choice especially for sports fans and teenagers who need the sound in a rather noisy place. It is easy to carry and can offer some nice sound quality to the ear while providing some level of noise-cancelling function by physically block them out.
Over-ear Headphones
Over-ear headphones sit on top of your head and use adjustable earcups to hold you ears. This type can be closed-back or open-back according to different purposes. Open-back headphone allows air to go through the earcup from the back of the speaker driver, thus making the resonance and low-frequency sound very robust, however, it provides less privacy and you can barely use it with noises around. Regarding the close-back headphones, the sound could be less natural and the low frequencies might be too strong, but the privacy and noise-proof is much better.
On - ear Headphones
On-ear headphones have smaller earcups compared with over-ear headphones. In terms of sound quality, there are no major differences between over-ear and on-ear type, but on-ear headphones are generally lighter and easier to carry. The only type difference would be on-ear headphones can not have ANC(active noise cancellation) function, which would be a important spec for certain type of people.
Bone Conduction Headphones
Bone conduction headphones are unique for its style and sound system. Instead of blocking the ear canal, this type of headphone send vibrations to the bones in the inner ear, making it possible for hearing-disabled people to use.
Bluetooth Headphones
Bluetooth headphones are also known as wireless headphones, using Bluetooth technology to connect two devices via radio waves. The best part of this kind is the convenience of getting rid of the pesky cord while sacrificing part of the sound quality. There are different forms of this type including earbuds, headphones and bone conduction as mentioned above.
Specs of different headphones:
Despite all the different forms of the headphones, they do share some common traits regarding the sound quality. There are some specs to judge their performances on the most basic level without taking their unique features into account.
Headphone drives
The driver functions as the element that transmits and converts electrical signals into sound waves perceivable for the user. Manufacturers often emphasizes on the diameter of their drivers due to the fact that it is generally considered the larger it gets, the better sound quality it can offer. That is particularly true for low-frequency sounds.
Sensitivity and sound pressure
Sensitivity means the ability to perform on the largest volume. This trait is also referred to as the sound pressure. This parameter indicates how efficiently an electrical signal is transformed into a sound wave and it also helps to understand how the volume changes the voltage.
Impedance (electrical resistance)
Impedance is measured in Ohms which indicates how much power is required to boost the headphone. The higher it is, the more energy it needs.
However, low-impedance is not exactly the perfect solution. The current low-impedance headphone requires often tends to bring vibration and noise, causing perceivable background hiss when running.
Frequency response
Frequency response indicates the frequency range the headphone can produce, which is measured in Hertz(Hz). The higher number represents the higher notes while the lower number brings bass sound.
The curve of frequency response can help to choose the type of headphone that suits the demand, for instance: if the bass sound is important, choose the ones with lines fall late into the deep base, if the headphone is used for singing, choose the ones that is heavy on the mid-range frequencies where there is no major rise and fall, if the headphone needs to resonate on trebles. Choose the ones with good extension in the high frequency range and seemingly flat in that area.
Total harmonic distortion (THD)
Total harmonic distortion refers to the amount of distortion happens to the sound, which is usually more perceivable at a high volume. This happens because the headphones produce sound via vibrations on the diaphragm, which might not be vibrating fast enough at high volumes and causing the sound distortion, the smaller it is, the better it sounds.
However, low-impedance is not exactly the perfect solution. The current low-impedance headphone requires often tends to bring vibration and noise, causing perceivable background hiss when running.
