Headphones are becoming the absolutely necessary device of our lives that we use in our routines, but the question is, how do wireless headphones work?
In a short time, wireless headphones have become fashionable accessories that allow us to listen to music everywhere and also to stand out with beautiful design. We’ve lived with them and keep thinking about the technology behind the wireless headphones that make them work.
In this article, we are going to explain how wireless headphones work.
Introduction of Wireless Headphones
Wireless headphones are based on technology that receives signals from various sources and transmits them by converting them into sound. Best wireless headphones under 200 claim suitable battery life and are all designed well with required accessories.
How Do Wireless Headphones Work?
As the name suggests, wireless headsets receive their audio signals wirelessly, rather than through headphone cables (often referred to as “wired” headsets). Wireless headphones have built-in receivers that accept wireless waves that carry the audio signal that the headphone drivers are supposed to drive. This “radio signal” is rightly called a carrier wave.
The transmitters effectively encode the audio signal into a wireless format (the carrier wave) and broadcast the wireless signal through the air. The expected audio signal is called the modulation signal. This modulation signal is encoded into a carrier wave that is wirelessly transmitted to the receiver.
The carrier waves used to transmit the signals from the wireless headphones are either in the radio frequency range or in the infrared frequency range. You can skip to the sections of this article that explain these carrier waves in more detail by clicking the links in that paragraph.
It is important to note that the carrier wave is a single frequency wave within the ranges mentioned above. Audio signals typically consist of frequencies in the audible range of 20 Hz to 20,000 Hz. The wireless receiver is designed to read the carrier wave and decode the modulating signal (audio signal) of the wave.
Wireless receivers must be set to accept the specified carrier wave frequency. If the audio signal is digital, it is converted to an analog audio signal. The analog audio signal is then amplified to properly drive the headphone drivers.
To summarize, let’s review the chronological steps involved in transmitting audio from a wireless headset:
- The audio source sends its audio signal to a wireless transmitter.
- The radio transmitter encodes the audio signal (modulation signal) into a carrier wave.
- This single-frequency carrier wave propagates in space.
- The wireless receiver, tuned to pick up the single-frequency carrier wave, accepts the wireless signal and efficiently decodes the audio signal.
- The digital audio signals are then converted into analog signals via a digital-to-analog converter (if the headphones are designed for this).
- Headphone drivers (transducers) convert the audio signal (electrical energy) into sound (mechanical wave energy).
- Aside from the method by which the audio signal is carried from the source to the headphones and internal DAC / amplifier, wireless headphones behave like wired headphones.
What Range Can I Expect from Wireless Headphones?
The range of the wireless headphones is about 10 to 30 meters and the measured distance is the optical distance. Some barriers or other interference will affect range, so pay attention to all aspects when measuring range.
How Long Will the Wireless Headphones Battery Last?
The battery of the wireless headphones depends on various factors such as the quality of the battery, its type, its built-in capacity, and the frequency of use. But the average battery on wireless headphones lasts between 25 and 30 hours.
Why Choose a Wireless Headset?
Why choose a wireless headset? Why not other types of headphones. There are so many reasons to choose a wireless headset. Some of them are as follows.
If you’re listening to songs as low as 128 kbps or MP3 tracks, you won’t feel much of a difference with wireless headphones. However, if you are listening to a high-quality soundtrack, you may experience some glitches when using wireless headphones. However, if you can buy extensive wireless headphones from a quality sound provider, you’ll be fine.
All in all, if you don’t have a problem with wires and cables then wired headphones offer better sound quality.
If you are an athlete, you will better understand the benefits of wireless headphones. Because when you are playing a sport, gym, or other physical activity and you run that fast or just walk that fast, the wires can cause so much disruption and a whole range of problems.
By using wireless headphones, you can solve all of your problems and focus on your work.
If you use wired headphones and try to buy wireless headphones now, you may find that wireless headphones are more expensive. But when you compare the capabilities, quality, and portability, wireless headphones are worth more than the real price.
Wireless headphones have additional features like play, pause, and jump buttons that you can use without taking your device out of your pocket or pocket. At the end of the day, it all depends on your priorities. If you want to get rid of cables and wires and have no problem with the sound quality, you can buy cheap wireless headphones.
And if you want crystal clear sound quality and want to use bass and all sound effects, you have to pay a little more for it.
Wireless headphones are modern technology these days. And they work with radio or infrared signals. The range of wireless headphones is 10 to 30 meters. And the battery of the wireless earbuds can last between 6-30 hours. It also depends on the module of a wireless headset.
Wireless headphones are the best options to use as these types of headphones are more compatible, have good sound quality, are affordable, and are wireless too. So overall, we prefer your wireless headphones to wired ones.
