In 2019, with the upgrade of the Bluetooth chip, the TWS Bluetooth headset also transitioned from version 4.2 to 5.0.
Some manufacturers directly replace the hot-selling products from 4.2 to 5.0, so the product appearance is the same, but the product operation is different, the actual application feedback to the market, consumers do not understand the specific differences, the following will describe in detail :
The difference of the chip in theoretical data:
1. Compared with the Bluetooth 4.2 version, Bluetooth 5.0 can bring twice the data transmission speed and increase the data transmission capacity by 8 times. In other words, using Bluetooth 5.0 can transmit and receive more data at a faster speed.
2. Compared with Bluetooth 4.2 version, Bluetooth 5.0 has increased the bandwidth (transmission speed) from 1Mbps to 2Mbps, and the transmission distance has been increased by 4 times, that is, the theoretical effective working distance is 300 meters, and the low power consumption mode is also available.
3. Compared with Bluetooth 4.2 version, Bluetooth 5.0 can broadcast 255 Byte data packets instead of 31 Byte, thereby reducing the loss of transmission efficiency caused by 2.4GHz band interference.
4. Compared with Bluetooth 4.2 version, Bluetooth 5.0 also strengthens the indoor and outdoor positioning, that is, it can pass much more information to other compatible devices, without the need to establish an actual connection.

Differences in feedback on actual product applications: 1. TWS Bluetooth headset 5.0 is compared to 4.2, and automatic pairing has been implemented, that is, the headset leaves the charging base and automatically starts pairing. If the charging base has a Hall switch, the headset is automatically powered on the moment the lid is opened. Pairing mode, while the Bluetooth headset version 4.2 is basically manual mode boot pairing. 2. TWS Bluetooth headset 5.0 is compared with 4.2. When making and receiving a call, there is sound in both ears, while in Bluetooth headset 4.2, when making and receiving a call, only the main ear has one ear.
