What is the difference between a true wireless headset and a wired headset?
They both have their own advantages and disadvantages.
In general, the technology of wired headsets is more mature and the cost is relatively lower.
True wireless headsets are emerging products, they have made great progress in recent years, such ad sound quality, latency, etc.,
The main differences between the two are as follows:
1. Different Appearance:
True wireless headsets do not have any wires, and they can be used once out of the charging box, which is very convenient!
Wired headsets come with wires, which are easy to entangle. In addition, nowadays, mobile phones are popular to cancel the earphone jack, so more and more people tend to use the true wireless ones.
2. The transmission principle is different
True wireless bluetooth headset realizes wireless transmission through bluetooth chip.
Wired headsets transmit audio signals through wires.
3. The internal structure of the headset is different:
True wireless headset, in addition to implanting a sound unit, a Bluetooth module, battery module, etc. will also be implanted inside. It needs to Pay more attention to the structure and design.
Wired headsets only need to focus on the sound unit inside, The headset cable is composed of three lines, the left channel signal line, the right channel signal line and the common ground line.
4. Different sound quality effects:
Due to the reliance on wires to transmit audio signals, wired headsets have better sound quality without loss.
True wireless headset, transmitting audio signals through Bluetooth, the audio signal will be compressed, transmitted to the Bluetooth headset and then decompressed by the decompression module, and converted into an audio signal that can be understood by human ears!
In the process of compression and decompression, the audio signal will experience varying degrees of loss, causing so-called distortion.
However, true wireless headsets are more and more popular now, many headset manufacturers are working hard on compression algorithms. At present, there are many technologies that are close to lossless sound quality, such as the commonly used Bluetooth standard compression algorithm SBC, Android phones are generally SBC, Apple's AAC, Qualcomm's apt-X, SONY's LDAC, etc.
