There is a leap in the sound quality of earbuds in each generation of earbuds. SONY MDR-XB90EX was one of the best choices when it came to selecting an earphone that keeps quality for generations. It used to be one of the best bass earbuds under 100.
It gives the best sound quality at its price range. Regardless the mirific listening experience, as the price is now around the $300 price tag (it used to be less than $100 in 2017 however the price increased as the cost of production as well as demand increased)
