The timbre of this kind of USB flash drive is really different from that of ordinary USB flash drives. However, the publicity of this kind of USB flash drive is exaggerated, such as vinyl chip, lossless audio, 6D sound effect and so on. For example, the concept of vinyl is a record, and a U disk is a carrier for storing data. Digital signals only need to be stored in -1. Can vinyl still be put into the chip? It's a concept. According to this theory, you also have a vinyl chip in your mobile phone.

regarding lossless audio, what are the compatible audio files for all models? That's just an MP3 file! Other lossless audio formats are not compatible with all models, so the music file in the U disk is MP3! The volume of an MP3 is 3-5M. Friends who listen to songs with cool dogs know that there is a high sound quality option, and the file size will be doubled, which will improve the music details to some extent, but it will definitely not have a thoroughly remoulding effect. As for the 6D sound effect, it's just a gimmick.

however, the sound effect of this kind of USB flash drive is better than that of ordinary USB flash drive when it is used on vehicles without sound modification. Why not say that the timbre is better? Because sound effects have nothing to do with timbre. As we all know, car stereos, which have not been modified, have thin timbre, lack of low frequency, dark middle frequency and weak high frequency. The listening environment in the car is complex, which is very different from the listening room. The effect of playing a set of audio in the car will be far worse than that of playing indoors. Therefore, in order to pursue timbre, someone will spend money to modify the sound, and only the luxury car sound will be better. For example, the sound of Berlin will be configured.

most car stereos are bland when playing music, because the source of music is standard and universal audio, which is suitable for all audio equipment, including headphones. Therefore, the various frequencies in music will not be decorated too much, and the pursuit is the original flavor. And some high-end stereos have high fidelity, deep dive at low frequencies, bright midrange and slender treble, so HIFI stereos will also have excellent effects in playing ordinary music. HIFI pursues a sense of live restoration.

and why does the modified car stereo feel better when playing ordinary music? In fact, this is the effect of DSP processor, which can also be said to be an equalizer. In view of the listening environment in the car, the sound quality has been modified and some frequencies have been moderately improved. That is to say, the frequency of music is modified by hardware, and the effect you hear is the effect after DSP processing. For example, the low frequency is boosted, the intermediate frequency is moderately enhanced, and the high frequency gain is improved. The essence of DSP is adjustment, so every sound engineer can adjust different sound effects. By delaying the signal processing, better sound effects will be driven.
