What is True Wireless Stereo (TWS)?

Introduction

In this article, we go through a brief historical timeline explaining how True Wireless Stereo (TWS) technology came to market plus some interesting facts we have learnt selling and using Bluetooth audio devices over the years.

The early 2000s was our first recollection of a wireless Bluetooth earphone when mobile phone provider SONY Ericsson launched the T39. Voice call communication was achieved but it was never designed for high-resolution audio.

By 2008 (TWS) technology made some positive strides when Sennheiser released the MX W1 which came with two earpieces able to transmit audio to each earpiece.

The MX W1 were not Bluetooth compatible because it worked by a small matchbox-sized transmitter that had to be strapped with a small elastic band to a device that can be plugged into any 3.5mm AUX input using the short audio cable from the transmitter.

Sending the same audio to a pair of True Wireless earphones at the same time is the focus of this example and not so much the connectivity side because the importance of connectivity will play a key part later on.

The World’s First Bluetooth Earbuds

In 2015 Japanese electronics company Onkyo show-cased the W800BT’s as the world’s first True Wireless Stereo in-ear earbuds at the IFA exhibition in Berlin Germany.

We cannot confirm if the Onkyo W800BT earbuds were ever released fully into the market, but they are certainly the blueprint to a vast variety of earbuds available on the market today.

Instead of having to attach a transmitter via 3.5mm jack-plug, it used Bluetooth technology across any device with a built-in microphone for hands-free calls and portable charging case with its own internal battery for charging on the move.

Up to this point, TWS earbud earphones was a niche market in the UK due to the heavy price tags, but then came the Apple Inc with the very popular AirPods, released in December 2016. According to the counterpoint hearables research 2020 the TWS market beat expectations in 2019 with Apple to continue dominating in 2020.

This Is How True Wireless Stereo Connectivity Works

First, you have to turn on Bluetooth on your chosen device. For this example, we are going to connect a pair of our EDIFIERS TWS200 Qualcomm Bluetooth Earbuds to an Android Smartphone which has a very simple setup process, here is how the technology works.

The diagrams confirm that transferring sound through True Wireless Stereo technology is very easy to accomplish with just a press of a button thanks to a small Qualcomm Microchip built-in to the earbuds which transmits the audio signal to your chosen source device i.e. smartphone.

Advantages of True Wireless Stereo Technology

  • Cable free earphones for easy movement and no length restrictions.
  • Single pairing option means you can use one earbud at a time.
  • Delivers high quality audio in comparison to some older Bluetooth versions.
  • Better handsfree option for drivers and motorcycle riders.

Disadvantages of True Wireless Stereo Technology

  • Battery life has a limited life before needing a recharge.
  • Sound quality may defer depending on the type of earbud manufacturer being used.
  • Risk of losing or damage is higher compared to some wired equivalent earphones.
  • There is a learning curve in relation to Bluetooth pairing and device compatibility.

It is important to mention the improvements in Bluetooth advancements since the introduction of version 5.0. This upgrade provides stronger connectivity, longer battery life and sharper audio experience.

Conclusion

It is important to mention the improvements in Bluetooth advancements since the introduction of version 5.0. This upgrade provides stronger connectivity, longer battery life and sharper audio experience.
