The biggest advantage of Bluetooth headset is that it eliminates the fetters of connecting wires. It can be used within the connection range of 10 meters without restriction. It can be directly operated on the Bluetooth headset to complete music switching and phone answering. It is especially convenient to use a Bluetooth headset when driving or playing sports.

When making phone calls from the car, you can easily solve this problem by using a Bluetooth headset without losing important information.

Bluetooth headsets are compatible. With the increasing number of electronic devices that can be connected to headsets, compatibility is an issue that must be addressed if Bluetooth headsets are to become more popular. Many Bluetooth headsets can support Bluetooth devices of different systems, such as phones, tablets, laptops and so on. There is no need to worry about the case that they cannot be used because of the different interfaces.

Despite above, the drawbacks of Bluetooth headsets are also quite objective.

1. The main disadvantage of Bluetooth headsets is the low transmission rate due to the bandwidth problem. APTX technology with high quality sound quality can transmit 300kps audio signal, while SONY LDAC technology can transmit 900kps audio signal, which can reach the lossless standard. If the file number rate is 256kps when listening to music, the APTX and LDAC Bluetooth headphones have no problem. If it is a cheap Bluetooth headset, the transmission rate may be relatively low, not up to high quality or lossless standards, which reduces the quality of listening to music.

2. The Bluetooth headset is different from the traditional analog wired headset. The Bluetooth headset transmits digital signals, so it is necessary to add a decoding chip on the Bluetooth headset to convert the digital signals into analog signals, and then amplify the output to the speaker. So the quality of Bluetooth headset needs to see the quality of the decoding chip.

3. Bluetooth headset needs battery to support its device and decoding module, so the battery life of Bluetooth headset is short. Bluetooth earphones need their own battery. To pursue lightweight, the battery capacity of Bluetooth earphones for communication is relatively small, and many low-end models can only talk continuously for 4 to 7 hours and standby for 5 to 7 days. The headset is designed for listening to music. Because of its large appearance, the battery life will be increased considerably.

4. The sound quality of Bluetooth earphones is worse than that of wired earphones of the same price and type. Firstly, it is because of the complex structure and high production cost of Bluetooth headsets. Secondly, the wired way of transmission is more direct and less interference.
