What are Bluetooth headphones

Bluetooth headphones come without a cable. You can make use of Bluetooth technology to connect wirelessly to your device. The headphones receive the digital audio wirelessly through the Bluetooth protocol when you pair them with the Bluetooth-enabled digital audio devices.

The Bluetooth headphones are almost similar to that of the wired headphones. However, the method in which they get & receive the audio signals are completely different. It is done through their drivers or transducers.

The idea of the headphone is to act like the transducer. The transducer converts electrical energy (audio signals) into sound waves. Transducers convert audio into the sound signals, therefore, are the important components of any headphone.

The wireless headphones work when an analog audio signal comes through the drivers. It then causes a proportional movement in the diaphragm. The movement of the diaphragm moves the air to produce audio signals that mimic the shape of the AC voltage of the audio signal.

It is required no matter the kind of driver than your headphones come with. You can find that the dynamic type if the commonly used in the market. One of the best examples of that is the Sony WH-1000XM4, which is a wireless headphone.

Why are they called Bluetooth headphones?

Why are they called Bluetooth headphones

You would be surprised to know that the term Bluetooth was conceived many centuries ago. According to history, the name Bluetooth was found in King Harald “Bluetooth” Gormsson. Kign Harald was popular for uniting Denmark and Norway in 958.

That is right. The shape of the blue brand is a mix of the Roman alphabet representing “H” and “B”. They are the initials for Harald Bluetooth. It is an image that is made of two runes that have been blended.

This radio technology was designed and released onto the market in 1989. It was done by Nils Rydbeck, CTO at Ericsson Mobile in Lund, Sweden. They wanted to design headphones that work without the use of wires and cables.

The headphones are pretty stable and offer you with a decent audio quality. When you are not satisfied with the ordinary Bluetooth that is meted out to you, then you can use high-quality Bluetooth codecs.

Then we have the battery life. Now, this can be a debatable topic. Though the battery life reduces each time, you use a Bluetooth headphone, it may not be the same with all models. For example, when you make use of a top-end model from Apple or Sony, then they can last a good 6-8 years without hassle.

Some of the units come with a battery time of 20 or more hours. Isn’t that amazing? Then you have to place them for charging. This gives you the freedom to use them where you want to. It could be the gym, office, travel, and so on.

Who should buy them

That is because they provide you with an eloquent audio quality. As a professional gamer, you do not have any degree of latency. These delays can cause you to lose the game or the race that you are playing.

Since these are Bluetooth headphone models, you may not want to wear them for more than 60 minutes. That is because of the harmful effects of Bluetooth that can cause radiation in your body. Moreover, it helps in protecting your hearing ability.

What are the factors to consider before buying them?

factors to consider before buying them

Bluetooth and sound quality

The first thing that you would want to note in the Bluetooth headphones is the sound quality. Now, the sound quality depends on the audio codec that you are using.

The codec is a software that encodes the audio at one end and decodes it at the other. That means, your headphones and audio player need to be able to support these features. The early versions of Bluetooth compressed the audio immensely.

That produced a harsh, digital sound. They then began to work on improving the audio quality with the introduction of the advanced audio distribution profile (A2DP). It enabled streaming of high-quality stereo audio.

This was possible through the SBC codec. Then we have the aptX. After that came the aptX HD, which is a high-definition upgrade. There is a growing number of devices that can support aptX HD.

Now, Apple devices do not support aptX on the iPhone or iPad. They make use of the AAC, which is an enhanced version of the SBC. You may want to know that the efficiencies in the codec make it comparable to aptX.


This is a main issue with the models. The latency is the delay that happens between the audio and the signal that is being sent to you when you can hear it. This is not that obvious when you are listening to music but playing games.

So, if you play games too often, then you might want to keep an eye on it. The latency depends on the hardware and software setups present on your devices. Please do note that the aptX HD has a reduced latency compared to the older codecs.

Battery life

It goes without saying that the battery life of the Bluetooth headphones is the most important factor to notice. They get to work using the built-in rechargeable battery. While some models come with powerful batteries that can last more than 18 hours, some models come with a battery life of 6-8 hours.

Then you have to place them for charge. This can be annoying considering the fact that they are Bluetooth models. However, you can charge them through the USB cable. Like we said, some models like the JBL Everest can work for 25 hours non-stop on a single charge.

Pairing Bluetooth headphones

The connecting ability of the Bluetooth headphones also have to be verified. You would be delighted to know that the W1 chip of some of Apple’s headphones has come down to 3 seconds.

Some headphones use NFC to increase the speed. It is possible only in the wireless technology and nothing else. Headphones can be paired with the device by tapping them against it. You can pair them manually if you want.

Remote controls in the wireless headphones

The wired headphones come with a remote on the cable. That is not required in the Bluetooth headphone. They come with some basic controls that are infused in them.

It has a microphone, form of buttons or touch sensors. There can also be a button to activate voice controls. Bose and Sony produce Bluetooth headphones that can work similar to the Google Assistant.

Form factor and size

Now, the wireless headphones have three sizes. They include over-ear, on-ear, and in-ear. The first two function like the wired headphones. The third option, which is the in-ear, is quite different.

Several devices make use of the Bluetooth technology that can make your connections easier. They can connect and exchange data on short distances using radio transmissions. Besides, they also let you connect to multiple devices simultaneously.

However, they do emit low levels of nonionizing radiation. It is not harmful to humans, and according to the Food and Drug Administration (FDA), exposure to nonionizing radiation is perceived as harmless to humans.
