Although more and more people use Bluetooth earphones with mic for music, they are compact and easy to carry. But as far as the current Bluetooth technology is concerned, Bluetooth headsets still have shortcomings. As China's leading Custom Headphone Manufacturer in China, JiaWeiHua will tell you what are the disadvantages of Bluetooth headsets?

There are five reasons:

(1) Bluetooth headsets generally have Bluetooth delay

When using  Bluetooth earphones with mic for music to play games and watch videos, the phenomenon of "out of sync" is called Bluetooth delay. Almost all Bluetooth headsets on the market have delays, and the delays are generally between 200-300ms. Numbers can basically make playing games lose the "sense of experience". You can imagine that the enemies are in front of you before you hear the footsteps. This is why many game masters use "wired headsets" to play games.

(2) Bluetooth headsets will more or less have "noise floor". This may not be felt by ordinary people and using better headsets, but for people with sensitive hearing, they can still hear many Bluetooth headsets. There will always be a “shasha/pap” noise floor. This is a problem caused by the internal circuit of the Bluetooth headset. If you have high requirements for sound quality, you may not be able to accept this. Then you can only use wired headphones to listen to music.

(3) The music transmitted by the Bluetooth headset must be lossy. This loss is due to the Bluetooth encoding protocol. Every Bluetooth headset has it. In a certain sense, different degrees of loss also become the judgment of the sound quality of this Bluetooth headset. One of the most common standards, such as the most common SBC, basically supports Bluetooth headsets on the market, followed by AAC, and apt-X. Generally, mid-to-high-end headsets will support this code;

So how big is the difference between these codes?

The answer is: "99% of people can't hear it", especially if the player you use is only a mobile phone and a computer, it will be even more difficult to hear. why? This is very similar to the compression format of "MP3", because human ears hear the common sense that "big sounds will definitely overshadow small sounds", MP3 specifically covers the part that most people can't hear "being overwhelmed by loud sounds." "Small voice" is removed to reduce the audio size. I also answered this in a previous article. Those who are interested can also learn more about it. The same applies to this Bluetooth decoding format. The difference between different levels is "loss The amount of audio elements", apt-X decoding will lose less, SBC will lose more, but no matter how much, the loss is the part of the "small sound" that is overshadowed by the loud sound, that is, most people listen to it. Unable to sound; people who pursue higher decoding generally have high requirements for sound quality. If you do not have a good playback device or do not have the excellent hearing that very few people have, then I personally think that blindly pursuing Bluetooth decoding The need for high-end audio is not great; therefore, for many enthusiasts, no matter how high-end the decoding format, it is still lossy music that naturally cannot meet the demand for sound quality, so they can only continue to use wired headphones. This is one of the reasons why Bluetooth headsets cannot replace wired headsets.

(4) There are many HIfi players that do not support Bluetooth connection. Many players have 3.5/6.5 interfaces. There is very little Bluetooth, which has a lot to do with the previous reason. After all, people who are accustomed to using players are right. The sound quality is still very demanding.
