honestly i was very excited to get this product at first but now after using it for about a month ive come up with this review1 sound quality is not excellent for anyone who loves to listen to songs on earphones that have rubber tips with good isolation but these are fairly cheap headphones too2 the whole thing about the thumping bass is a gigantic hoax im not sure if it has bass at all3 battery backup is good enough to keep you going for a day with average usage4 sound se
