I brought it for Rs 1, 700/-.the main featurer in this product is extra bass it’s really amazing, with micro speaker so that we can answer calls, play &pause button, with flat wire which is tangle free, but sound quality is amazing.it is totally made of plasticof good quality, I suggest you to buy this product.
