Reasons to purchase At the university, I had soaked some audio forums. I also learned from the jars that hydroelectric nuclear power had a negative impact on the sound quality. Unfortunately, my home was a thermal power source that could not be changed from the source. I had to start with hardware to improve sound quality. The family has a Passat version, the most common power, the most common audio, usually playing music with SD card, recently bubble XX home, get a conclusion, the car audio playback quality is CD> AUX> SD card >Bluetooth, due to the high cost of genuine CDs, and the fact that it is not cost-effective to buy a whole album for a song, it is secondarily followed by a decision to change the main playback method from SD card to AUX. Idle the hand of a Dafa X1060. The song inside was dumped all the way from college. It can be said to be full of sentiment, so I missed a pair of recorded lines and went online. Privately divided the recorded lines into three grades, followed by fancier brands, mass consumer joint venture brands, and domestic brands. Corresponding cards are as follows: In fact, I have always believed in HiFi metaphysics, but my wallet does not believe, and my car stereo is also not worthy of such high-end wire, so I have chosen China Green Union, known as silver plated wire, gold-plated plugs, and monsters. To make a comparison, it feels that your monster is more than ten times more expensive, but its performance is also about 20% higher through the brain. The back describes some product highlights Feeling high quality Engraved brand logo, exquisite sense of puff Resilient A plug-in machine AUX interface, a plug in the player The length was a bit slender, and the shortest 0.5 meter bought at that time was estimated to be too long if it was 1 meter. The wire is very strong, and the plug is also very delicate. If it is not destroyed by violence, it should be no problem to use it for 10 to 20 years. I do not know is the individual reason or other, the player through the AUX and the car machine always has annoying bottom noise, I try to change to a mobile phone, the noise still exists, and it is clear that the elimination of noise, car audio playback effect is indeed Have improved, treble crisp, midrange pure, bass rich, of course, the premise is that the player must be professional, is the so-called surgery industry specializing in the use of mobile phone playback, no difference between the effect and SD card, of course, if you use some Mobile phone with independent decoding chip, when I did not say Advantages: 1, affordable 2, excellent workmanship 3, the use of materials (although I did not dismantle, but I believe that domestic) Inadequate: not found yet Vacuum Cleaner Brushless Motor-BLDC Vacuum Cleaner Brushless Motor-Bldc,Brushless Motor Cordless Vacuum Cleaner,Brushless Motor Vacuum Cleaner,Vacuum Cleaner For With Brushless Motor Zhoushan Chenguang Electric Appliance Co., Ltd. , https://www.vacuum-cleaner-motors.com
