Bluetooth headset solution development

1. Introduction to Bluetooth headsets

With the rapid development of science and technology, more and more new thinking and new technologies have begun to truly affect our lives. With the upgrading of technology in recent years, the field of earphones has also started a huge revolution, that is, wireless bluetooth earphones replace wired earphones.

Wireless Bluetooth headsets have recently become the standard equipment for hipsters, fitness experts, and digital enthusiasts. The unfettered audio experience cannot be provided by wired headsets.

2. Types of Bluetooth headsets

Bluetooth headsets can be divided into mono type, stereo type, true wireless type (TWS technology), and noise reduction type. There are two types of noise-canceling Bluetooth headsets, namely environmental noise reduction and active noise reduction.

3. Advantages of Bluetooth headset solution

1. True wireless

As a new concept wireless Bluetooth headset, it realizes the wireless connection between the left and right ears. The outside of this type of earphone completely abandons the way of wire connection, and the left and right earbuds can work independently, so hands-free calls are under control. When you need to transform into a two-channel stereo, turn on the other earbud and close it to automatically form a two-channel stereo mode. When sharing music, you will not be tied down by wires, and it is more convenient to use.

2. Stereo

The stereo Bluetooth headset is based on the mobile phone supporting the A2DP Bluetooth stereo protocol. As long as the mobile phone supports the A2DP Bluetooth stereo protocol, then our Bluetooth headset can be connected to the stereo Bluetooth headset to enjoy Bluetooth headset music.

3. Excellent sound quality

With the large composite diaphragm dynamic coil, the bass is mellow, the midrange is soft, and the treble is bright. The sound quality is pure and transparent, and the listening experience is delicate and natural.

4. Easy to use

Built-in microphone for hands-free calling

Built-in lithium battery can be recharged cyclically (with charging box)

The headset can support up to 2 hours of call or music playback time when fully charged

5. How to use Bluetooth headsets

1. Bluetooth headset pairing steps

First, find the corresponding Bluetooth name from the Bluetooth list of the mobile phone and click to connect and pair. The voice prompt will be successful in about 5 seconds. The left and right earphones will have a soft "bang" sound to indicate that the connection is successful. To use the same phone again, you only need to take out the earphones from the charging compartment and the phone will automatically complete the connection and pairing operation. If you use it with another phone, you need to repeat the above pairing steps.

Then, open the charging case, the two earphones will be automatically paired, and then you can wear it to enjoy the functions of calling and listening to music.

2. How to charge the Bluetooth headset

Our bluetooth headset solution adopts the way of charging in the charging compartment. The principle is similar to using a power bank to charge a mobile phone, except that the charging interface type is a pocket type dedicated to the headset. The charging method is very simple, that is, put the secondary directly in the charging compartment, and it can be charged automatically.

3. Can the Bluetooth headset be charged together with the charging case?

It is not recommended to charge together, the best charging method is to charge separately. Because the charging case generates heat when it is charging itself. If it is allowed to charge the earphones at the same time, then in the process of charging and discharging, the heat will be higher than that of charging or discharging alone, making the product hot and hot, and there may be safety issues. Therefore, it is recommended that when you use the charging compartment to charge the Bluetooth headset, do not also charge the charging compartment at the same time.
