1. Must choose the 4.1 version of the Bluetooth headset?
The transmission effect of the earphone is mainly determined by the chip of the earphone. Now the Bluetooth earphone chip mainly includes the Broadcom of the United States and the CSR of the United Kingdom. The version of the Bluetooth chip on the market mainly has three versions of 3.0, 4.0, and 4.1. In fact, each version has its own characteristics.
Bluetooth 3.0 has been around for a long time, and the Bluetooth call transmission effect is the most stable. This is also the reason why 3.0 still exists today. Its shortcomings are relatively few functions, high power consumption, and low transmission rate.
Bluetooth 4.0 has a higher transmission rate, longer transmission distance, lower power consumption, enhanced wireless coverage, can be directly connected, no need to input passwords, and can also realize automatic connection, intelligent one-to-two functions, and a large number of compatible Today's digital devices.
Bluetooth 4.1 is an upgraded version of Bluetooth 4.0. It achieves higher HD and higher speed call effects on the basis of 4.0, and has more flexibility, but sometimes 4.1 compatibility is not stable, this should be noted.
2. How long is the headset life?
Life time determines how long your Bluetooth headset can last, and is divided into usage time and standby time. The decision on the battery life is related to the battery quality of the headphones and the volume of the headphones.
Most of today's Bluetooth headsets are based on polymer lithium batteries because of their small size, powerful power, long battery life and high usable life. The average Bluetooth headset has more than seven or eight hours of battery life.
The size of the earphone determines the size that the battery hardware can be assembled to determine the length of the battery life. Therefore, the larger the earphone, the larger the battery and the longer the battery life.
