What are True Wireless Earbuds?
True wireless earbuds, as the name implies, have no wires (or) cables connecting the two earbuds. These earbuds are packed in a case with two slots for each earbud. Each earbud has its own Bluetooth chip and antenna that allows them to connect, eliminating the need for a wire between them. “Piconet” is the ad hoc network that connects both earbuds via Bluetooth technology protocols. Although Bluetooth technology is used by many modern devices, some devices employ other wireless technologies such as infrared and radio frequency waves.
True wireless earbuds are equipped with a built-in battery, speaker drivers, playback controls, volume controls, and other functions. Additionally, these earbuds come with some advanced features like noise cancelation, water resistance, touch controls, voice assistant, and customized ear tips for delivering premium sound quality. Moreover, they can be easily paired with all Bluetooth-enabled devices like smartphones, tablets, laptops, and so on.
How do True Wireless Earbuds Work?
The working process of true wireless earbuds is neither magic nor a mystery. Its functioning is quite similar to regular wired earbuds with slight advancements. Primarily. Let’s break down the earbud and examine the parts to understand their functioning. True wireless earbuds are housed with four essential components namely: dynamic drivers for high-resolution audio, rechargeable battery, signal-boost antenna for Bluetooth connectivity, and beamforming microphones for crystal-clear calls.
However, here is the detailed working process of true wireless earbuds.
Firstly, pair your earbuds with Bluetooth-enabled devices such as a phone, laptop, tablet, etc.
[Note: if you encounter any trouble (or) unable to pair the earbuds, refer to the user manual]
|
| Once after establishing a reliable and stable connection with the audio source, wait for the earbuds to connect. As you know true wireless earbuds comprise left and right earbuds, even they must be synchronized. So, wait for a while to pair them automatically. |
| After pairing the earbuds, the audio source will wirelessly send audio content to the earbuds over Bluetooth. The audio data is delivered from the audio source to the primary earbud often the right earbud, which then transmits the audio signal to the secondary earbud the left earbud for synchronized playback. |
| Now, built-in receivers accept the audio signals from the audio source. Then they are sent to the transmitters where the audio signals are encoded into wireless waves and propagated through the air. |
| Finally, the audio signals are transferred to the amplifier, where they are transformed into sound signals and amplified to drive the earbuds drivers. |
| You can control music, volume, pair, turn on, turn off, and other features via touch-sensitive surfaces located on the earbuds. |
| To enjoy wireless streaming the power must be supplied to the internal batteries. Put the earbuds in their charging case, where they will be recharged and ready to use for the next time. |
As a recap, the following are the sequential stages involved in wireless earbuds’ audio transmission.
- First, the audio source sends an audio signal to the wireless transmitter.
- The audio signal is then encoded into a carrier wave by the wireless transmitter.
- Later, the wireless receiver takes the wireless signal and decodes it properly.
- DAC then converts digital audio signals to analog signals.
- The analog audio signal is amplified by an internal amplifier.
- Finally, the earbud drivers receive the amplified audio signal and convert them into sound signals which you hear.
Benefits of True Wireless Earbuds
True wireless earbuds not only look great, but they also feature a slew of advantages that set them apart from the crowd. Check out the benefits of true wireless earbuds.
| Less chances of slipping out | Wires often add a lot of weight to your earbuds, which is another reason they tend to fall out. Since true wireless earbuds don’t have any wires at all, they fit snuggly into your ears and do not fall out during intensive workouts as well |
| Ease of use | As true wireless earbuds don’t come with wires, you will have complete freedom in your movements without any restrictions |
| No more tangles | Traditional earphones often have wires which get tangled up frequently while on the go. But on the other hand, true wireless earbuds are completely cord-free. This feature frees you from having to deal with tangles and managing the wires |
| Great battery life | True wireless earbuds include a USB-C charging case, so they’re always charged and ready to go. These cases store an extra charge, allowing you to avoid being hooked to a wall more frequently. Instead, when you put them back into the case, they start charging automatically |
| Easily portable | Because of their compact size and unique design, they will not eat up much space and you can carry them anywhere easily in your pocket |
| Protective storage case | The storage case is robust and made of high-quality materials. They do more than just keep the earbuds charged; they also protect them from unexpected turbulence |
| Compatibility | True wireless earbuds are compatible with the majority of Bluetooth-enabled Android and iOS devices. They can be easily paired with your laptop, smartphone, tablet, and other devices with a single tap |
| Water-resistant | Water-proof (or) water-resistance technology protects the earphones from rain, water spills, and other liquid attacks. And, these days, most earbuds have this technology, allowing you to use them without worrying about sweat (or) water |
Moreover, these earbuds can be connected to any Bluetooth-enabled device seamlessly. And, today many devices use Bluetooth 4.0 (or) 5.0 technology for reliable and stable connectivity. Besides, some are equipped with the most advanced features like built-in voice assistant, noise-cancelation, noise isolation, touch controls, customized fit, and so on for delivering outstanding sound quality, and flexibility.
Limitations of True Wireless Earbuds
Every technology has its benefits and drawbacks. Even true wireless earbuds come with a few limitations, which are listed below.
| Expensive | True wireless earbuds may appear amazing with all of their modern capabilities, but they are quite expensive and may not be affordable to everyone |
