Seven Things to Know About TWS (True Wireless) Headphones

True Wireless Earphones
If you've ever struggled with the tangled wires of regular headphones, wireless headphones could be your lifesaver. With its wireless and compact design, whether we are listening to music, exercising, working, or doing other things on the go, TWS earphones can bring us an unparalleled wearing experience.

Faced with so many options on the market, how should we choose the TWS earphones that suit us? In this blog, let's dive into the knowledge base of TWS earphones.


We must first be able to distinguish between "truly wireless" headphones and "wireless headphones". Importantly, there are neither wires nor wires between the earpieces of "truly wireless" headphones. Since they have no wires, the microphone, controls, and battery are all built into the earbud's housing. "Wireless" headphones are still somehow connected,

2. What is the Difference Between the Bluetooth Version?

Open the specifications of the TWS headset, you will find that the Bluetooth version of the headset mainly has two versions: BT4.2 and BT 5.0. As the latest version of Bluetooth, BT5.0 brings many changes and improvements, including eight times the amount of transmitted data, twice the speed, and four times the range of BT 4.2. In short, Bluetooth 5.0 devices have better endurance performance and longer effective working distance, which is definitely a better choice for TWS headsets.

3. Bluetooth Chipset and Bluetooth Code.

We can think of the Bluetooth chipset as the brain of your device, it does the job of sending and receiving signals. Then the bluetooth code acts as your brain's way of thinking, which determines how the signal is compressed and decoded. These two factors together determine the stability and sound quality of TWS earphones.

In general, the larger, well-known Bluetooth chipset manufacturers offer a safe bet.

Then check which encodings are supported by the TWS earphones. The most basic model can only be used with SBC, it does not support higher-resolution music and generally sounds a bit flat. If you're an Apple user, check to see if your headphones support AAC. Apple devices only support SBC and higher-quality AAC.

4. Battery Life: in and out of the Box.

The battery life of a pair of TWS can be considered from two aspects: the first is the built-in lithium battery of the headset, which can provide 3-6 hours of playback time, and the second is the battery of the charging box, which can generally provide battery life from 12 hours to 48 hours. Battery life is of course also largely dependent on how loud you listen to music and whether you have ANC turned on.

5. What is the Difference Between ANC (Active Noise Cancellation) and ENC (environmental Noise Cancellation)?

ANC is designed to benefit headphone users only. ANC technology uses a built-in microphone to pick up noise and then generate sound waves identical to external noise. This eliminates ambient noise. The result is a listening experience unaffected by external noise.

In contrast, ENC is designed to benefit both headset users and the people they communicate with through the headset. In noisy environments, your teammates will also hear the ambient noise around you when communicating with you. ENC technology utilizes the built-in microphone to detect and cancel ambient noise picked up by the microphone. Enable users to communicate clearly with others.

6. Water Resistance: Prepare to Not Sweat

If one of your main uses for your TWS earbuds is to wear them while exercising, get yourself a pair of earbuds that are at least sweat-resistant. The waterproof standard of most TWS earphones is marked with IPXX, which is the abbreviation of "International Protection". This is an international standard for measuring a product's resistance to dust, dirt, and water. The first number after "IP" tells you how resistant the product is to dust, dirt, and other solids. An "X" indicates that the product has not been tested. Since most people aren't worried about dust inside their earbuds, most earbuds are rated IPX.

7. AI Interface Control

As TWS earphones become more and more popular, more and more advanced technologies are adopted to improve user experience. Go out and ask the earphones to use artificial intelligence interaction as the core technology. Most earphones have intelligent control functions such as gesture control and touch control so that you can truly free your hands whether you are exercising, listening to music, or outdoors.
