T 1 is the flagship product of Baiya, and it is said to be the first Tesla headset, which is a breakthrough in the headset industry. . When listening to classical music, the intermediate frequency is relatively concentrated and stable, and the high frequency is relatively bright. It is a semi-open earphone, and the sound quality density is also well controlled. . This headset is called 10,000 yuan HIFI on the Internet. I just heard it at an audio exhibition. I believe it should be equipped with a good front end to give full play to its strength.
