wireless noise cancelling earbuds

Without a doubt, wireless Bluetooth earphones wireless noise cancelling earbuds are one of the most innovative smart accessories launched in the last two years. It cancels the long connecting line of traditional earphones, which is more convenient to wear and use, and has been loved by many users for some time. Now in addition to Apple, there are many wireless earphones that are constantly being launched in China. With the cancellation of the 3.5mm headphone jack, we can only use Bluetooth headphones, and we have to feel that the development of society is really fast. But, you know what? Although the Bluetooth headset is convenient, it still has these three shortcomings, you must think about it before buying it!

Signal range

Bluetooth headsets can be connected wirelessly, and the Bluetooth versions used by headset products are different. The signal control range of the connection is also different. The longest distance of the Bluetooth 5.0 signal is about 10-15 meters, and the distance below 4.2 is even shorter, and this is not perfect for distances including walls or enterprise electronic technology equipment. interference.

battery life

Unlike wired headsets, Bluetooth headsets need to have their own charging or charging warehouse, so there will be some requirements on battery life. If you typically use more partners, you might consider a longer-lasting Bluetooth headset.

Delay

The first thing to understand is that both wired and bluetooth headphones have sound delays. Latency is caused by the time it takes for sound to travel from the phone or computer to the headset. For wired headphones, after the device generates a digital audio signal, the digital audio signal is converted into an analog audio signal through a DAC, and the digital audio signal can be directly transmitted to the headphones through the wire. The whole process is very simple, usually less than 10ms. The delay of sound is difficult for the human ear to perceive.

However, the research on the conversion and development process of bluetooth earphones is relatively long. Due to the limited bandwidth of data transmission through bluetooth, it is first necessary to compress Chinese digital audio into a bluetooth technology protocol audio code, transmit it to bluetooth earphones, and then perform self-decompression on the earphones Convert it to digital audio, and then convert it to DAC to simulate different audio. After this long process, the sound reaches your ears. It is precisely because the processing time of Bluetooth headsets is much longer than that of wired headsets, which also explains the reason why the delay of sound information is much higher than that of our country.
