The headphone from Sony priced at around 600 rupees or in a sale you can get it for about 450 rupees is the best budget headphone anyone can find.I bought it for rs.450 from flipkart.The bass delivered by the audio drivers is great.The build quality is not so good as it is made up of entirely plastic , but considering the price point of the headphones it is not the deal breaker.The only con in this headphone is the amount of treble. I feel that the treble could have been little boosted.But above all, it is the best you can get in around 600 rupees.The 5 star rating is given considering the value for money.
