TWS technology is not limited to devices like earbuds or chargers. The actual meaning of TWS that its a technology that allows connecting devices via Bluetooth.

So all those devices which are not connected physically but connect via Bluetooth fall under TWS technology.

So always remember there is a difference between the TWS earbuds and TWS technology. However, earbuds and chargers are some devices using TWS technology extensively.

The technology was first introduced by Apple, where they came up with this technology and started providing earbuds with their Apple Phone, and nowadays, the TWS earbuds are in trend.

What is TWS Earbuds Mean

TWS in earbuds means the earbuds are accessible without any cable, and you can connect it via Bluetooth. Moreover, the TWS technology allows you to transmit the L channel, your left earbud, and the R channel means the right earbud separately.

The significant advantage of TWS earbuds is you don’t have to start connecting with the cables to stick to your phone or PC for your work.

These earbuds allow you the freedom to move without being sticky in a place. 

How does TWS Bluetooth works in earbuds?


TWS  earbuds comprise 9 components: Speaker, audio codecs, Bluetooth, the system on a chip or SoC, PCB (printed circuit board), Lithium-Ion battery, accelerometers, and MEMS microphones, and some of them use Noise cancellation.

The first set of circuit boards has the Bluetooth chip, accelerometers, and the SoC, which compresses the audio stream sent from the smartphone.

From the first circuit board, another board is connected, which contains an audio codec associated with the battery and antenna.

The same circuit board holds the MEMS microphones and the small two circuits charging the earbuds, and once everything gets assembled, we get our TWS earbuds.

Types of TWS earbuds technology?


TWS are basically of two types the one is single-source earbuds, and another is dual-source earbuds. Let me explain it a little more to understand the difference between them.

• Single-source earbuds:-  The single source earbuds primarily connect with one earbud from the source device and pass the signal to the secondary earbuds.

• Dual-source earbuds:- These earbuds tend to connect both earbuds direct from the source. That means you can able to use only one earbud at a time.

Types of TWS earbuds


There are two types of TWS earbuds available one is Half In-ear, and another is Full In-ear. The same is shown in the image. 

• Half In-ear:- The Half In-ear earbuds are best for those looking for earbuds for casual use. 

• Full In-ear:- The Full In-ear earbuds are for those looking for the best earbuds for exercise like running, Gym, and many more. 

TWS earbuds vs Wireless Headphones

The significant difference between the Wireless earphones and TWS earbuds is obese the wire. Yes, you read it right. 

If you observe, the wireless earphones are not connected with the wire with their sources like smartphones or Laptops but are internally connected with themself.

However, the TWS earbuds do not have any connected wire to connect them internally.
