TWS101: What is True Wireless Stereo (TWS)? Why do I need it?

Over 68 million pairs of true wireless stereo earbuds were sold in the first quarter of 2022, yet another sales record. TWS earbuds continue to increase in popularity with each new model release, and this trend shows no signs of abating.

Transmission of stereo sound over Bluetooth wirelessly is the "art" of true wireless stereo technology. A tiny chip in both the sending and receiving devices facilitates wireless communication. The best wireless equipment (headphones/phones and microphones) eliminates the tangle of wires that can be so frustrating.

Not only should you not use a cable to connect several such devices to the system and the audio system, but you should also not connect such devices. They are available in a wide range of sizes, with batteries that, depending on the model, may last anywhere from 12 to 15 hours. Lower-priced headphones and earbuds often have a lower battery life (between 4 and 8 hours).

What is True Wireless Stereo Technology?

Bluetooth signals are used in True Wireless Stereo (TWS) to transmit sound. TWS is different from wireless gadgets that only work when they are near a media source; they still need to be physically connected for everything to work properly. One great example is the wireless sports headphones that connect with a cable the user wears around their neck.

On the other hand, real wireless accessories are truly wireless in every sense. There is no need for cords to attach the earbuds or speakers or to connect them to a device that can play audio. Bluetooth chips provide a wireless connection.

What is the function of TWS technology in headphones?

Before reliable wireless technology became available, wireless headphones and earbuds still required a wired or wireless link between the left and right channels. In contrast, true wireless headphones eliminate even the short cord and equip each earbud with its battery, digital-to-analog converter (DAC), amplifier, and Bluetooth chip.

Each set of headphones has its cable to connect to the audio source or the headphones used to manage the audio source, and then another set of headphones to which the digital signal is sent. Each earpiece is detachable, yet they coordinate to provide stereo sound from whatever is being listened to.

The apparent benefit of this design is the enhanced comfort and ease of usage that comes from hearing every sound in the room. It's useful in various contexts, from the workplace, busy public spaces, airplanes, and when you want to lie in bed and listen to music on your headphones.

For hands-free phone calls, look for wireless Bluetooth earbuds like the Cleer ALLY PLUS II with a built-in microphone. With a decent microphone, wireless headphones are the most convenient and effective means of carrying on a phone call.

While several things may add weight to in-ear headphones, many modern alternatives feature sleek, lightweight designs that fit snugly and don't need wings or ear hooks to keep them in place.

Is Bluetooth the Same Thing as True Wireless?

The True Wireless Stereo system is a Bluetooth-based system for transmitting audio. Despite what the name would lead one to believe, it is not a standalone signal. When paired with a source of sound, the Bluetooth signal carries the sound from the source to the receiver.

Bluetooth facilitates communication between mobile and stationary devices using a short-range wireless technology standard. It's limited to local connections and LANs. A Bluetooth signal may travel up to 10 meters in the open air.

Earbuds no longer need wires, thanks to Bluetooth transmissions. Connecting them to a sound system allows for convenient and cord-free listening.

Bluetooth is different from cordless earbuds. Earbuds that don't need wires provide sound messages through radio or infrared. Bluetooth-enabled users perform the same thing by exchanging data over short-range radio waves.

There is a delay in Bluetooth and all other wireless audio communications. Latency is the delay in a signal caused by its journey between two devices. The lag might be in milliseconds, depending on the Bluetooth implementation of the data transmitter.

Benefits of using TWS

Full independence

If you invest in high-quality wireless equipment, you can listen anywhere. Keep your hands free when you dance on the opposite side of the house, and refrain from using your phone at any moment. After becoming wireless and tangle-free, you won't want to go back.

Complete adaptability

As you already guessed, total liberty entails a great deal of adaptability. When you can't listen to your music, you are alone, or you only have one ear, share it with your buddies. These earrings are appropriate for any occasion. Please go to our Frequently Asked Questions section for a comprehensive analysis of when you should wear your TWS headphones.

Keep the harm to a minimum.

Just because your headphones have TWS in the moniker doesn't make them bulletproof. However, because there are no cables present, destruction from wires is avoided. Using regular headphones, particularly low-quality ones, might disrupt the signal. This occurs most often when the cable is plugged into the jack for your headphones, rendering one or both of them useless.


True Wireless Stereo (TWS) technology has changed the way we listen to music by eliminating the need for wires. TWS earbuds' popularity has skyrocketed because of its practicality, mobility, and high-quality sound. TWS earbuds are ideal for music lovers, commuters, athletes, and anybody else who wants a hassle-free audio solution because they don't become tangled and don't impede movement’s earbuds are already rather advanced, with characteristics like long battery life, high-quality sound, and customization options that appeal to a wide spectrum of users.


 What is True Wireless Stereo (TWS) technology?

TWS, which stands for "true wireless stereo," is a wireless audio technology that allows two earphones to operate independently of one another and of a playback device. With TWS earphones, you may enjoy wireless stereo sound from your connected device and the earbuds themselves through Bluetooth communication.

 How do TWS earbuds work?

TWS earphones link to a media player through Bluetooth, which might be a phone, tablet, or computer. With the ability to receive audio signals individually, each earbud can faithfully replicate the left and right stereo channels.

How is the sound quality of TWS earbuds?

Thanks to improvements in audio technology, many TWS earbuds do, in fact, produce high-quality sound. However, there might be noticeable differences in audio quality between various makes and models. Before buying something, it's a good idea to do some research and maybe even give it a try first.
