Guys Sony is one of my favorite company. I have purchased Sony MDR-XB450 extra bass Fold able Headphones last month. After listening to it, I was amazed at the bass it produced. Complete justification to the title of this product. Very clear and crisp. I use these headphone with phone and it produced awesome sound quality. Headphone come with flat wire which makes tangle free. The pads are thick and very comfortable. The colour and built quality is good. So, please use this product.
