Bluetooth stereo and wired stereo what is the difference?

The same price range of Bluetooth audio sound quality is not as good as wired audio.

One, the sound quality is different:

It is subject to the cost of Bluetooth audio in more related chips, Bluetooth transmission technology bandwidth is not enough to transmit lossless audio signal, Bluetooth decoding will also have an impact, in addition to the wireless transmission will be a packet loss phenomenon. Focusing on the sound quality performance, it is recommended to choose a wired audio product in the same price range.

The same price of Bluetooth audio and wired audio sound quality comparison, due to Bluetooth audio need to join the Bluetooth chip and decoding chip, in the cost will be higher, in addition to Bluetooth transmission technology will lead to audio signal compression in the transmission, to a certain extent, will affect the sound quality.

2, the transmission technology is different:

Bluetooth 4.2 transmission rate is 1Mbps, Bluetooth 5 and Bluetooth 4.2 compared to the theoretical transmission rate doubled from 1Mbps to 2Mbps, this transmission rate is equivalent to the general MP3 resolution is sufficient, if the transmission of lossless and the current HiRes audio is obviously a little bit of a struggle, the need for data compression to achieve an effective audio quality. This means that you will need to compress the data in order to achieve an efficient transfer.

3, the environment is different:

Because of the wireless transmission, by the current electromagnetic environment is more complex, in the transmission of the phenomenon of packet loss, the sound quality will also cause different degrees of impact;

Expansion of information:

Maintenance of audio

1. Take care to prevent covering. Please be careful not to place other items on the amplifier clutter (such as DVDs, tablecloths, etc.) This facilitates heat dissipation.

2, with audio to the correct boiler. Many people mistakenly think that audio can be bought directly to any use, in fact, not. Audio needs a period of time to break in, after the break-in audio can really play out its charm, that is, boiler.

3, speaker cleaning. Available soft dry cloth to clean the speaker system, do not place a sprayer on the side of the system or let the liquid penetrate into any openings, can not use any chemical solvents or medicines, or the use of alcohol, ammonia-containing liquids or sandpaper to clean the machine.

4, normal operating temperature. Normal operating temperature of audio equipment should be 18 ℃ ~ 45 ℃. Temperature is too low will reduce the sensitivity of the machine; temperature is too high is prone to burn components, or make components premature aging. Audio equipment should not be direct sunlight, but also to avoid close to heat sources, such as heaters, refrigerators and so on.

5, to be regularly energized. In the case of long-term non-use, especially in the humid, hot season, it is best to energize half an hour a day. This can use the heat generated by the components inside the machine to drive away moisture, to avoid internal moisture, mold.
