The Current Sounds and Bottom Noise of Bluetooth Headphones
We all have different feelings and opinions about the current sound of Bluetooth Headphones, because everyone can hear the frequency of the audio differently, you can refer to the professional headphone reviewer to do "Wake up your ears (next episode)"
There is confusion between the two concepts of current sound and noise, first of all, Bluetooth headphones have current sound which is definitely not normal (a quality problem), but Bluetooth headphones bottom noise is definitely there, now the current market of Bluetooth headphones are not possible to do 0 bottom noise, can only be optimized to reduce as much as possible.
Current sound is the "sound" of a very weak electrical signal being amplified by the irregular thermal movement of the electrons in the components, and the "hissing" sound heard after the volume is turned up will increase with the volume.
Bluetooth headset bottom noise is generated by the AMP amplifier and other components in the Bluetooth headset bottom noise, which is generated by components such as AMP amplifiers in Bluetooth headphones and then transmitted to the sound generating unit, is all that manufacturers can do to optimize the design of the sound generating unit and circuitry to minimize bottom noise. Each headset in the factory will be set up before its original frequency response curve, but this curve in different frequency bands set the high and low peak is not the same, plus each person's ear heard the frequency is also different, even if the volume is adjusted to the lowest or even 0 volume, in fact, the frequency response curve of the headset is still there, so some people will hear a similar "current sound This is because some people will hear a similar "current sound" and some people will not hear it.
