Everything you should know about True Wireless Stereo Technology

By Cleer Audio

True wireless stereo technology is the "art" of transmitting sound over the air via Bluetooth. Wireless transmission is supported by a small chip built into the source and receiving device (device). Good wireless devices (earphones/phones and microphones) have many good features, but the most important thing is that there are no cables.

This not only means that you should not connect two or more of these devices to the system and the sound system with a cable, but also that you should not use the cable. They come in all shapes and sizes and have a variety of batteries that can last up to 12 or 15 hours, depending on price and quality. Cheaper headphones/earphones have shorter battery life (4 or 5-8 hours per charge).

A good wireless device can be used alone or as a series of devices connected. They are very small and can be used in different parts of your house, or even outside if the quality of their design allows.

What is True wireless stereo technology?

True wireless stereo technology is the "special technology" of wireless audio streaming via Bluetooth. A small chip installed in the source and sink equipment enables wireless communication (device). It is called Real Wireless Stereo (TWS) because it allows you to enjoy real stereo sound without cables or wires.

How does Qualcomm's TrueWireless Stereo Plus technology differ?

Qualcomm's TrueWireless Stereo Plus technology sends the signal to the left and right ears at the same time, instead of using the more traditional 'daisy-chain' method, with one earpiece on the other. This greatly reduces latency and speeds up the wireless connection. Like today's wireless headphones, TWS headphones communicate via Bluetooth using the 2.4 GHz band. The specific communication method depends on the Bluetooth chip in the headset and mobile phone.

The most popular and traditional method is where one of the first or the first audience is announced. This headset receives the signal (audio) from the mobile phone and transmits it to another handset so that it can reproduce the sound of this "part" (channel).

Although in the process of thinking our ears we do not understand a deviation of the signal that is played on the left and right channels, we still want the headphones (and the device we play music) to support the latest version of Bluetooth. The latest Bluetooth devices have implemented the Bluetooth Low Energy standard, which saves the battery of connected devices a lot, and has all the other advantages of the new technology, such as double and quadruple bandwidth.

In addition, the old version of Bluetooth has a high latency between connected devices, which is particularly noticeable in Android, where the Bluetooth signal from an application (such as Deezer or YouTube) to our ears passes through the software and hardware chain.

In practice, we have noticed that some TWS headphones based on the Bluetooth 4.2 chip have a slight delay for images when playing and watching videos on services such as YouTube.

When listening to music, the issue of latency is less important, because you have no reference to determine the delay in the signal (like moving your mouth).

How do headphones with TWS technology work?

Until good wireless technology came along, wireless headphones and earphones had some sort of connection between the left and right channels, either wired or wired. With real wireless headphones, even the short cable is gone, and each earbud has its battery, DAC, amplifier, and Bluetooth chip.

The headphones connect individually to the source device or control headphones that are connected to the source and then connect to a second headphone to provide a digital signal. In this way, each earpiece can work independently, but both work together to ensure that the listener receives stereo sound from the source device.

The obvious advantage of this design is the quality of the experience of listening to the air completely, which improves comfort and ease of use. It is helpful in many usage situations, including when you are working, in crowded places, travelling, or when you want to use your headphones while lying down.

Good wireless Bluetooth earbuds much like the Cleer ALLY PLUS II usually include a built-in microphone, allowing it to be used as a hands-free device with your phone. As long as the microphone is good enough to pick up sound from a distance, this makes wireless headphones the smartest and most efficient way to have a phone conversation going.

And while other factors can make in-ear headphones heavier than regular headphones, many new options have compact, lightweight designs that are comfortable and don't rely on wings or ear hooks to stay in place.

The benefits of TWS technology

Thinking about switching to True Wireless? Here are three advantages of this modern headphone.

  1. Total freedom

When you buy good wireless, you have complete audio freedom. Don't use your phone at any time; leave it on one side of the house while you dance on the other side, completely hands-free. Trust us: once you're wireless and tangle-free, there's no going back.

  1. Total versatility

As you may have understood, having complete freedom means having all kinds of flexibility. Share your music with your friends when you're away or only wear one ear at a time. You can wear this kind of earrings anytime, anywhere. Check out our FAQ section below for a detailed review of the best times to use your TWS headphones.

  1. Minimize potential damage

Just because there's TWS in the name doesn't mean your headphones are indestructible. However, the absence of wires prevents wire-related damage. When you use standard headphones, especially cheap ones, you run the risk of breaking the connection. This is mainly when the wire is connected to the headphone jack, which means one or both of your headphones stop receiving sound.

In summary

Since its inception, True Wireless Stereo Technology in audio industry has been a game changer in wireless audio. These devices have conquered the market and are becoming more and more popular.

Continued advancements in technology such as BA drivers, MEMS microphones, edge-to-edge DSP, connectivity, software, and AI algorithms will contribute to this rapid growth and adoption of new features in TWS devices.

Improved sound quality and advanced AI features will bring consumers the best experience from their TWS devices. Wireless Noise Cancelling Earbuds like Cleer ALLY PLUS II are making a big difference.
