I bought this headphone because my old headphone jbl j03 stopped working. That was a good headphone for its prize. So I wanted a headphone thats under 2000₹ and has good bass. Checked many reviews online and bought sony mdr xb 450 and I was blown by the bass it produces. Even jbl which is known for its quality bass camt match sony. Sony has been a trustable brand when it comes to audio.the headphone has good bass , sound sound quality , good build quality , quality wires , great comfort and the list goes on. The things I dont like is low trebble and sound tends to crack at high volume feels like uncontrolable. Overall a great product. It works even more great with an equilizer
