Big-name bose and Sony can be considered if the budget is above 1000 yuan, and NineKa headphones can be seen if the budget is in 500 yuan. Recently, it has been highly discussed and recommended by many digital and running experts. I've personally been working on NineKa headphones for some time. Although it is not as exaggerated as the advertised sound quality of 1000 yuan, I can't find my opponent at the same price. Indeed, the sound quality and comfort are very pleasant.
