It depends on the acoustics of the Bluetooth ear (such as the number of speakers in the earphone, the size of the moving coil, the size of the diaphragm, and the professional debugging effect).

Sports: Sports listening to songs is also the main purpose of Bluetooth headsets. Generally, you need to choose a Bluetooth headset that is light, fit, and not easy to drop. It can be used with both ears and ears. If it is a binaural ear, pay attention to the thickness of its line.

If you care about wearing comfort, then it is recommended to go to the store to wear the experience before buying.

4, 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. 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 Bluetooth call transmission is the most stable. It 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, direct connection, no need to input passwords, automatic return 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. It has more flexibility, but sometimes 4.1 compatibility is not stable. Please pay attention to this.

5. How long is the headset life time?

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 headset and the volume of the headset.

Most of today’s Bluetooth headsets are based on polymer lithium batteries, because of their small size, powerful functions, long battery life and high usable 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.related articles http://ts80hou.com/en/buy china mobile.html
